Machine Tool Bearings: Making Manufacturing What it is

10:17, 11/6/2012 .. 0 comments .. Link
Since before the very earliest days of the industrial revolution, machinery has managed todramatically alter the fabric of our lives and our day-to-day interaction with the many things that have made the world an increasingly connected place. Whether the machine in question is a simple wooden lathe or an extremely advanced and precise machine tool, responsible for grinding and drilling sensitive components, machines of every complexity rely on bearings to give them the motion they need to keep doing what they do to provide the products we use every day. As one of the most essential components of machine tools everywhere, the performance and reliability of the spindle bearingare absolutely critical. After all, machine tools work every day to create and manufacture products with their capability to move in the productive ways they're engineered to do so. Without effective spindle bearings, those spindles would not be able to move, and the machine tools would be rendered virtually useless. When it comes to machine tools, the speed, precision, rigidity, and resistance of the spindle bearing directly influences the performance of the machine, the quality of the finished product, and by correlation, the efficiency, energy consumption, and profitability of whoever is doing the machining. tapered roller bearings have also become increasingly important over the years, especially due to pressure to conserve energy and contribute to "green" business practices. With this in mind, significant development has been made to produce high-speed and eco-friendly machine tools, which rely on machine tool bearings that help to achieve that efficiency. Machine tool bearings are usually deep groove ball bearings, cylindrical roller bearings, angular contact ball bearings, thrust bearings, and tapered roller bearings with an extremely wide variety of configurations and structures. When it comes to the precision of machine tool bearings, the bearing precision is divided into a variety of different grades ranging from p0 to p6. In this case, ultra high precision machine tools require p4 or greater bearings. Other specific varieties of high-speed machine tool bearings often take advantage of ceramic materials for their ability to perform at high speeds and lower temperatures than other materials. This makes ceramic and ceramic hybrid machine tool bearings an ideal solution for high speed and high precision applications. Regardless of the kind of bearing used in machine tools, under most circumstances a "machine tool bearing" refers to the spindle bearings that ensure proper motion in the machine. Given the fact that machine tools help manufacture so many of the things we take advantage of today, the bearings that make them move are equally integral. So next time you take something like your car or your computer for granted, think about what went intomaking it so readily available. Chances are, machine tool bearings were there to help.

Something about Bearing Manufacturing Process

At present, parameters of the internal structure of China's sealed Deep Groove Ball Bearing are almost the same as that of foreign products. However, the level of vibration and noise of such products is very different from that of foreign products. It is mainly resulted from the manufacturing factors and working conditions. From the point of view of the bearing industry, the working condition factors can be considered through making reasonable demands on the main engine. However, how to reduce vibration and noise that are caused by the manufacturing is become an urgent problem for the bearing industry. Many tests from home and abroad show that: the processing quality of the cage, bearing ring, and steel balls has different effect on the bearing vibration. Among all of them, the processing quality of steel balls has the most significant effect on the bearing vibration. The main factors that have influences are roundness of bearing rings, the waviness, surface roughness and surface bump and hurt. The most prominent problem of China's steel ball products is that vibration value is large. The surface has serious defects (such as single point, cluster points and pits). Even though the surface roughness, size, shape and errors are not lower than the level of outside rings, the bearing vibration value is very high after the combination. The main problem is that the ripple is not controlled. As to the rings, most serious impacts on the bearing vibration are the channel waviness and surface roughness. For example, if the circularity of inside and outside channel of small and medium sized Deep Groove Ball Bearing is larger than 2m, it will have distinctive effect on the bearing vibration. The waviness is resulted from grinding as to the steel balls and rings. Although superfinishing can improve the waviness and decrease roughness, the most fundamental measure is to reduce the grinding process of waviness and avoid random bump and hurt. How to reduce noise of ball bearing? There are two points which should be taken into consideration. One is the manufacturing process. The refinement of the manufacturing process mainly refers to the shortness of the process and the combination of the process and manufacturing. The process of the manufacturing should be clean. Besides, bearings should be produced in a large scale for this can improve the competitiveness in the world market. The other is the equipment. High-speed grinding, spindle accuracy, stiffness and many other detection performances have much impact on the grinding accuracy and efficiency.

Deep Groove Ball Bearing is the simple mechanism, convenient used and widely sphere of application bearing. It is the most common type in rolling bearing. This kind is mainly used to carry radial load, also a certain degree of axial load. When increasing the radial clearance, it has the nature of the angular contact ball bearing, and it also can withstand large axial load. It is usually composed of an outer ring, an inner ring, a row of steel balls and cage. A Deep Groove Ball Bearing is formed on each inner and outer ring enabling them to sustain radial and axial loads in either direction as well as the complex loads which result from the combination of these forces. It mainly bears radial loads, but it can also bear a small amount of axial loads. Axial carrying capacity will increase when selecting large radial clearance. It has the minimum friction loss and the maximal limit speed when compared to other types of the bearing. Their cages are mostly wave-shaped steel stamping cage, large-scale vehicle system use entities bearing cage. Their basic types are open, with double-sided or double-ring ceremony with dust cover, in production, with sealed bearings in the outer ring can be mounted on the open ring of the dust cover or trench. Pressed cages are generally used in deep groove ball bearings. However, machined cages are used for large bearings and high speed bearings. Firstly, it can be mainly used to bear radial load, but also bear certain axial load, when the bearing radial clearance time increased with the performance of angular contact ball bearings can bear large axial load. Secondly, it has a simple structure and it is very easy to maintain. Thirdly, it has solid durability, versatility and low noise operation. Fourthly, it can operate at high speed and easy to install. It is suitable for precision instruments, low noise motors, automobiles, motorcycles and general machinery, the machinery industry, the most widely used class bearings.

Features and Structures About Rolling Bearings

10:07, 11/6/2012 .. 0 comments .. Link
Rolling bearing is a very important type among all different bearing categories. Therefore, it is rather necessary to have a clear idea about this type. The construction of the tapered roller bearings is the basic knowledge for you to learn. Most of them consist of rings with raceway (inner ring and outer ring), rolling elements (either balls or rollers) and cage. First of all, let us see the raceway. The "raceway surface" refers to the surface on which rolling elements roll. The contact surface can support the load that is placed on the bearing. It is common that the inner ring and outer ring are placed at different places. Generally, the inner ring fits on the axle or shaft, whereas the outer ring will be placed on the housing. Secondly, let us see the rolling elements. Basically, they can be classified into two types, i.e. balls and rollers. The latter ones can be further divided into four types: cylindrical, needle, tapered, and spherical. Thirdly, let us see something about cages. There are also many different kinds of cages such as the pressed cages, machined cages and formed cages. They can prevent the rolling elements from falling out. Now let us move to the classification of rolling bearings. They can be classified to ball bearings and roller bearings. As to the former, there are different ways to further classify them. For example, they can be further divided into Deep Groove Ball Bearing and angular contact type according to ring configurations of products. If we classify them according to the shape of the rollers, there are four types. They are cylindrical, needle, tapered and spherical. Besides, if we classify them according to direction in which the load is applied, there are radial bearings and thrust bearings. It is no doubt that roller bearings have many special characteristics. Compared to many other kinds of bearing products, they have many advantages. For instance, most of them can carry both radial and axial loads at the same time. Their rigidity can be improved by preloading. Except for this, these products can be easily lubricated, thus, they will consume less lubricant. Some commonly applied rolling bearings are deep groove ball bearing, angular contact ball bearing, thrust ball bearing, cylindrical roller bearing, needle roller bearing, and thrust roller bearing, etc. All these different products are quite important in industries. They can be applied in various places to meet customers' requirements.

Structures and Performance Characteristics of Five Types of Bearings

10:04, 11/6/2012 .. 0 comments .. Link
1. Thrust Tapered Roller Bearing Because the rolling body in thrust tapered roller bearings is the tapered roller, and the structure of the rolling roller bus and bus washers are the axis lines intersect at a point bearing, which can form pure rolling on the surface, with speed higher than the thrust cylindrical roller bearings. They can bear axial load in one direction. And their type code is the 90000. Due to their less production, most of the types the plants have produced are in non-standard shapes and sizes, while when it comes to standard series, species production is relatively fewer, and thus there is no such national standard for present dimensions of bearing. 2. Thrust Angular Contact Ball Bearing Generally, the contact angle of this type is 60 . Commonly used angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used in precision machine tool spindles. And they usually used with double row cylindrical roller bearings which can bear two-way axial loads, with advantages of high accuracy and good rigidity, low temperature, high speed and easy assembly and disassembly. 3. Double-row Tapered Roller Bearings There are various structures about this type of product, among which the most massive is the 35000 type. This kind of bearing may withstand the bidirectional axial loading at the same time when bearing radial loads. Moreover, they may limit the axis and the outer covering axial shifting in bearing's axial float scope. 4. Deep Groove Ball Bearing It usually has simple and easy structure. It is the most common type in rolling bearing. It is usually composed of an outer ring, an inner ring, a row of steel balls and cage. It mainly bears radial loads, but it can also bear a small amount of axial loads. Axial carrying capacity will increase when selecting large radial clearance. 5. tapered roller bearings The type code number of this type is 30000. It is a kind of separating bearing. Generally, the addendum circle angle as well as outside the roller conveyer diameter size has been stipulated same as the external dimensions by the standardization. They are mainly used to bear both the radial loads and the axial loads. When compared to the angle contact ball bearing, their bearing capacity is bigger, and the limitation speed is lower.

Tapered Roller Bearings

09:59, 7/6/2012 .. 0 comments .. Link
Tapered roller bearings are similar in construction to cylindrical roller bearings except that instead of the cylinders being perpendicular to the ring, they are angled and offset. This construction has the added benefit of additional load support and the ability to spin the bearing more quickly. They are used often in the automotive industry and heavy equipment industry.

Advantages :
1. The first benefit of the tapered roller bearing is its cone shaped design. Each roller in the bearing can align itself perfectly between the tapered faces of the cup and cone, without guidance by the cage. That is a major development in bearing design and operation. The large end of each roller has been ground so that it is square against the rib along the back of the inner race . Without the "rib," rollers would be forced from the cage. As each roller revolves about the cone, a wide area of contact is made between the large end of the roller and the rib. This wide area of contact compels each roller to maintain accurate alignment. With each roller perfectly aligned between the two races, the bearing works to maximum productivity. Each roller has an equal share in the total workload.

2. The second benefit – the bearing's ability to support radial and thrust loads simultaneously – is a result of its internal design. A radial load on a tapered bearing produces both a radial and thrust reaction. The rib restrains the rollers and counteracts the load.

3. One construction feature makes tapered roller bearings unique from most other designs: the races are separable. When mounted, the inner race (cone) and rollers are assembled as one unit and the outer race (cup) as another. Industry standards in size and design permit cups and cones to be interchanged when necessary.

Introduction to Tapered Roller Bearings

Tapered roller bearings are roller bearings with a capacity to carry large axial forces. They are in good thrust that can withstand high radial forces as well. In tapered roller bearings, inner track ring and the outer ring raceway segments and got the pin when the rollers are made of a cone so that the conical surfaces and the bed of the shaft of the roller, when there are finally meets a common point of the main shaft bearings.

This conical geometry is used because it gives a greater contact area and better allows for large loads can be transported in non-spherical ball bearings. tangential velocity in the roller surface are actually the same for the whole length of the bed and touch the surface. This leads to the prevention of the difference between rubbing. Rollers to guide the inner ring of the collar, which prevents them from slipping out at high speeds because of an extract from them.

Tapered roller bearings are separable and consists of the outer ring, inner ring and roller assembly. The inner ring and roller assembly, which can not be separated is called the cone while the outer ring is called the cup. Tapered roller bearings are used in the pair back in the car and rear wheel bearings of vehicles, where they are exposed to radial and axial forces.

Deep Groove Bearings

Among other types of ball bearings, the deep groove bearing is the most common and consists of an outer, inner ring with steel balls and cages. These are used as radial bearings and has the ability to operate at very high speed.Deep groove bearings are actually a non separable bearings that can carry axial loads  in both the directions. It consists of uninterrupted raceways that are also deep. The ring grooves are in the form of circular arcs that have radius more than that of the radius of the ball. Height of inner ring shoulders is equal to outer ring shoulders. Contact of the ball with raceways is point and elliptical when loaded.

Types of Deep Groove Bearings
Low Friction
Small Shielded
Large Shielded
Sealed ones are made from the synthetic rubber and oil with the sheet steel reinforcement. These can operate in wide range of temperature i.e. between -40° C to 120° C.Low friction seal types can also operate between the same temperature range as the sealed ones. It is the kind of non-rubbing bearing as the a narrow gap is formed by the lip of the seal with the land of inner ring.Small shielded ones have a sheet steel shield making a long sealing gap.Large shielded has no cylindrical section and preferred when the rotation of the inner ring is required.

Things About Deep Groove Ball Bearings

09:53, 7/6/2012 .. 0 comments .. Link
A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as well as by the directions of applied loads they can handle. There are many different types of bearings among which the ball bearing is rather common. They have various applications. They are commonly used in machinery industry and in wheels of vehicles like cars, buses and motorcycles. It is very important to maintain them. If the maintenance is done properly, the life span of these products will be maximized.

When they are installed in the shaft, they can limit the axial displacement of the shaft or housing in both directions within the axial clearance. Therefore, they can make axial positioning in two directions. Additionally, this type of product has a certain ability of aligning. Most of their cages are steel stamping ribbon cages. The manufacturing costs of them are relatively low. In addition to basic models of deep groove ball bearings, there are still many others such as deep groove ball bearings with dust cover, or with a rubber seal ring and double row deep groove ball bearings, etc.

There are many advantages of this kind of bearing products. Firstly, they are suitable for high speed and high rotation operation. Secondly, they are very durable even without regular maintenance. Thirdly, they have small friction coefficient and low costs of manufacturing. Fourthly, they have various sizes and models which can meet different requirements. Like many other kinds of bearing products, deep groove ball bearings also have a wide range of applications such as gearboxes, instruments, motors, pumps, household appliances, internal combustion engines, agricultural machinery, construction machinery, and engineering machinery.

Things About an Angular Contact Bearing

09:37, 7/6/2012 .. 0 comments .. Link
Angular contact bearing is a kind of ball bearing. It is able to carry radial load and axial load at the same time, meanwhile, it can also endure pure axial load, together with high limited speed. The carrying capacity of axial load is decided by the contact angle, the bigger contact angle, the higher carrying capacity of axial load. They are widely used in heavy industry, such as manufacturing, chemical and agricultural, etc. Moreover, they can also be applied in turbines, heavy transportation equipment like airplanes.

It can be further divided into other types such as single-row angular contact ball bearings and double-row angular contact ball bearings. The former one can only carry axial load from single direction, and additional axial force will be caused when carry radial load, and the shaft and housing are only restricted moved in one direction. And as to the latter, if paired bearings are installed, make a pair of outer ring opposite, that is wide faces and narrow faces are opposite separately, which can avoid additional axial force, and also limit shaft and housing into the axial clearance range in two direction. And the single-row angular contact ball bearings are mainly used in spindle of lathe, motor with high frequency, gas turbine, centrifugal machine, front wheel of small auto, and differential gear shaft. And the double-row angular contact ball bearings are mainly applied in oil pump, roots blower, air compressor, all kinds of gear box, fuel injection pump, and printing machinery, etc.

Since they are so important products in our industries, it is quite necessary for us to know something about its operation. Generally, the angular contact bearing's races (metal surfaces between the bearing balls) and bearing balls are installed at an angle, typically of 15, 30 or 40 degrees, relative to the bearing's operating axis. This design enables the bearings to handle loads with both a radial and axial component. And there is also much friction which is caused by the radial-axial load combinations. This kind of bearing can work to greatly reduce the tremendous amount of friction.

All in all, the angular contact bearing is an important category of ball bearings. Its application is very wide. And it can be used to meet various requirements.

What Is a Deep Groove Ball Bearing?

10:35, 4/6/2012 .. 0 comments .. Link
Are you familiar with the deep groove ball bearing? If not, this article will help you broaden your eyes. Here you can get a general idea about this bearing. Commonly speaking, this bearing is often composed of a pair of ferrules, a group of retainers and a group of rigid spheres. Its type code is 6 and it is a very common bearing. Owing to its simple structure and convenient usage, this bearing is widely used in different equipments.

The deep groove ball bearing mainly supports the pure radial load. At the same time it also supports the radial load and axial load. When it only bears the pure radial load, the contact angle is zero. When the bearing has a wider radial clearance, it gains the nature of the contact angle bearing and supports the large axial load. Compared with other bearings in the same size, this bearing has a very small friction coefficient and quick limit speed. Especially under the working situation with a very large axial load, it has more advantages than the thrust ball bearing. After the bearing is installed on the axis, the displacement of the axis can be controlled in the range of the axial clearance.

Because this bearing has the simple structure and can easily achieve the high manufacturing accuracy, it is quite convenient to produce it on a large scale. According to different structures, there are a lot of deep groove ball bearings such as deep groove ball bearing with a dust cap, deep groove ball bearing with rubber sealing ring, deep groove ball bearing with a snap. Although they have some differences, all of them have the following features. In the first place, form the perspective of the structure, there is a continued groove raceway whose cross section is about one third of the sphere circumference on every ferrule. The function of this raceway is to support the radial load and axial load. In the second place, with the increase of the radial clearance, the bearing can support axial bearing which is altered at two different directions. In the third place, the friction is very low but the rotating speed is quite high. Last but not least, the stamping wave type retainer is often used. But for the bearing with more than 200mm inner diameter or with high rotating speed, it is better to adopt the vehicle-made retainer.

Bearings Are Backbone For Machine

10:33, 4/6/2012 .. 0 comments .. Link
The life span and proper functionality of machine completely relies on the quality of bearings. The major role of bearing is to provide the frictionless shifts and movement between the parts of the machine. And hence it is made up of silicon nitride and stainless steel. The coating of titanium carbide makes the bearing to rotate in all range of speed without any complication. Stainless steel resists the body of the bearings from all kind of environmental changes. Pacamor Kubar Bearings, ABI Industries, Schaeffler Group USA, Pacific International Bearing and Shuster Corp are legendaries in manufacturing bearings.

In all rotary devices the contribution of ball bearing is very important for a safety and durability. Hybrid materials and ceramic are used in making of high quality ball bearings. Radial and thrust are two types of ball bearings whereas generally these are ring shaped. Ball bearings used in aerospace application like turbine and transmission. It designed in such a way to endure combination loads and reversible thrust. The whole weight of aircraft gets transformation from airframe to the ground only through the landing wheels in meanwhile extreme heat is generated and accelerates from 0 to 2000 RPM. So either it is small airplane or commercial aircraft tapered roller bearings are implemented in wheels to make a safe landing.

Tapered roller bearings is one of the aerospace bearings there are few more different design are in exist for several parts of aircraft. Cylindrical roller bearings are mainly used in gearbox and turbine engine. It controls the function over extended range of speed. Needle Roller Bearings are used for the purpose of moderating the speed in application of high load within small space. It implemented in landing system and airframe of aerospace and in helicopter rotor blades. Spherical roller bearings are used to moderate the capacity of thrust load and also combine the capacity of radial load. Precision ball bearings are not only used in aerospace but also in all general industry like machine tool, health, and robotics. These super precision ball bearings are manufactured to tolerance class operations. It fits the requirements like machine uptime, rigidity, high speed and accuracy. The main application of this bearing is in grinding spindles, milling spindles, boring spindles, speed routing, vertical or horizontal spindles. It features either 15 or 25 degree angels in thrust and radial combination.

In case of bearing maintenance, there are few things to be noted carefully. First and fore most is the quality of the component and certainly it is not safe to use low quality bearing in high heat generating machines. Design would be the next consideration, obviously there are highly sophisticated designs are available to fit the different demands of machines and aircrafts. And above all the density of lubrication is very important for the proper maintenance of bearings.

Spherical roller thrust bearings are specifically designed for handling high loads, serious misalignments, severe applications, vibrations, and shocks. A spherical roller thrust bearing has the highest rating for load handling in the industry and thus, almost all manufacturers and distributors sell roller thrust bearings. The friction level of a roller thrust bearing is much lesser than other types of radial ball bearing products. This helps to maintain a low operating temperature and also facilitates less consumption of lubrication and power. The speed, although a little lesser than other bearings, is also increased in the advanced versions, allowing more scope and environments of application.Unlike other bearings, spherical thrust bearings go through an exclusive heat treatment to maintain the stability of their dimensions. The temperature capacity in for the metallic cages in these bearing can measure as much as up to 200 degree C. They are also capable of handling real severe misalignments with maintaining the same load capacity. There are a variety of spherical roller bearings available in the market. The YM spherical roller bearings belong to the one piece brass cage with machined, finger type. These bearings have one piece roller riding machined brass cage and are designed for severe environmental conditions. The load ratings of these items are very high.The other type of one piece brass cage finger type roller bearings are land piloted and are known as YMB. The feature specifications, usage, and application areas of this type are similar to that of the YM type roller bearing. The YMD type has two piece brass cage and belong to the finger type, land piloted group. Along with the similar features of one piece brass cage bearings, these bearings have more advanced features to suit extreme conditions and a last for a longer period of time. The CJ type has a two piece steel cage and belongs to the window type with a cage of stamped steel. These bearings are used for a variety of applications. Some of the other types of spherical roller bearings include the C, CA. CD, and EA. While the C, CD, and EA types have pressed steel cages, the CA type has machined brass cages. Oil grooves and holes are present on the outer rings for lubrication.Accessories used with spherical roller bearings such as locking devices and bearing sleeves are easily available in the market. These accessories are found in different dimensions and sizes to match the both kinds of shafts (straight and stepped). The latest addition to the designs available is the new range of sealed and split spherical roller bearings. Although based on the standard designs, these new bearings can be customized as per the job requirement and condition.

One Kind of Roller Bearings--- Tapered Roller Bearing

Roller bearing is a very important category among all the different kinds of bearing products. Compared to ball bearings, they have higher radial load capacity. This kind has disadvantages, too. For example, they have a low axial capacity and higher friction under axial loads.

The roller bearings can be future divided into cylindrical roller bearing, spherical roller bearing, taper roller bearing, etc. Among all these kinds, the taper roller bearing is quite important. They can take large axial forces, besides, they are able to sustain large radial forces. They are composed of many parts such as the outer ring, inner ring, and roller assembly which contain the rollers and a cage. The non-separable inner ring and roller assembly is called the cone, while the outer ring is called the cup.

This kind of product has a very long history. At the end of the 19th century, roller bearings came into being. Actually, it is in the year of 1898 that the famous bearing company called Timken was awarded a patent for the tapered roller bearing. And it is this product that makes the company become quite successful. Due to the development of the tapered roller bearing, journal bearings which function on the basis of the lubricants are replaced for that they will fail if there is no proper lubrication. The failure is caused by the friction. Fortunately, the Timken succeeded in creating the tapered roller bearings which can reduce the friction by using a cup and cone design.

It is no doubt that the appearance of the tapered roller bearing brings customers a great surprise. They can withstand high accelerations and decelerations, heavy loads and a variety of temperature and environmental conditions. When compared to other kinds of roller bearings, they can support both radial and axial loads. Because of its greater contact area, they can take higher loads. They have a wide range of applications such as the helicopter transmissions, speed reduction transmissions, gas turbine engines and so on. Addition to this, they can also be commonly applied in many simple machines like most cars, trucks, and buses.

Due to the complexities of the manufacturing process, they are usually more expensive than ball bearings. Although they have this disadvantage, this kind of bearings is still widely accepted by customers. They can not be replaced by others in some occasions. And people can choose these products for their special features to meet requirements.
