Roller Bearings Higher, More Professional Requirements
Jun 05, 2017

Reducer as a power transmission mechanism, in the current for the transmission of power and movement of the body, the application of a wide range of reducer. With the continuous development of science and technology, various industries for the reducer requirements continue to increase. Corresponding to the reducer for its supporting parts of the requirements are getting higher and higher, especially for high precision and rigidity of the higher and more professional.

The following are the same as the

However, most of the current domestic reducer are low-end products, such as harmonic reducer, RV reducer and robot reducer and other high-end reducer is mainly dependent on imported brands, especially in recent years to show the head of the robot and the field of aviation And so the pursuit of light limit, LCD, semiconductor manufacturing equipment by the system production line height restrictions, are in the pursuit of "ultra-thin" limit. In these industries use high-end reducer also tend to high-precision, small size, modular and functional, these high-end reducer made a higher, more professional requirements.

The following are the same as the 

High-precision cross-roller bearings as the main bearing, showing other bearings irreplaceable superiority, in the high-end reducer in the gradual replacement of other conventional bearings, precision cross roller bearings are generally built on the output side of the reducer as the main bearing , Combined with the main body of the reducer as a whole, the first substantial reduction in the volume and expand the scope of application; the use of rigid precision cross roller bearing built-in way, the load can be directly applied to the output, get a higher torque; At the same time, reduce the difficulty of the combination and the overall cost.

High precision cross roller bearings Use:

1. Machine tool: turret knife indexing, indexing plate, loader

2. Robot: rotation, joint drive

3. Semiconductor manufacturing equipment: handling robots, inspection platform

4. LCD manufacturing equipment: handling robots, inspection platform, photosensitive agent coated roller drive

5. Printing machine: photosensitive agent coated roller drive

1, thrust roller bearings into the thrust roller bearings should be flexible after the rotation without blocking sense. If there is a clear rotation is not flexible, it means that the size of the shaft is too large, the tolerance to be reduced. Such as thrust roller bearings into the shaft after the hand by hand there is a clear "rust" feeling, it may be too much tolerance of the shaft or shaft roundness is not good. So in the control of shaft and thrust roller bearing room tolerance to control the roundness, the current domestic manufacturers only to control the tolerance, there is no control of the roundness.

  2, thrust roller bearing assembly: Because the thrust roller bearings are high-precision products, such as improper assembly is easy to cause damage to the thrust roller bearing channel, resulting in damage to the thrust roller bearings. Thrust roller bearings in the assembly should have a dedicated mold, can not be tapping, in the press into the shaft when only a small circle of force, pressure circle can only large circle force. Assembly requirements of the use of air pressure or hydraulic pressure in the upper and lower mold to be outside the horizontal state, if the tilt will lead to thrust roller bearing groove due to damage to the force, leaving the thrust roller bearing guide.

  3, the installation of foreign body to prevent: thrust roller bearings in the load on the rotor to do when the dynamic balance is easy to balance the iron into the thrust roller bearings into the internal, so it is best to install thrust roller bearings before the dynamic balance The There are some manufacturers in order to facilitate the assembly, the assembly in the thrust roller bearing room coated with some oil or grease from the lubrication effect, but often the operator is difficult to control the amount of good, if the oil or grease in the thrust roller bearing room accumulated more , It is easy to enter the thrust roller bearing along the shaft when the thrust roller bearing is rotated. Thrust roller bearing room is best not to oil or grease, if not coated can not be controlled in the thrust roller bearing room can not stay.

  4, the prevention of paint rust: paint rust is characterized by multiple in the sealed motor, the motor sound in the assembly is very good, but put some time in the warehouse, the motor varies greatly, remove the thrust roll Sub-bearing a serious rust phenomenon. Many manufacturers will think that before the thrust roller bearing the problem, through our continuous publicity, and now the motor factory has been aware of the problem is mainly insulating paint. The problem is mainly due to the insulating material of the acidic material in a certain temperature, humidity, the formation of corrosive substances, the thrust roller bearing channel corrosion caused by thrust roller bearings damaged. The problem is currently only a good choice of insulating paint, and after the ventilation in a period of time after the assembly. Thrust roller bearings in the use of the process, the most important is the length of life. The length of life and bearing manufacturing, assembly, use are closely related. In the use of the process must pay attention to the daily maintenance.
