Smoothing method for rolling bearings

Rolling bearing is an important mechanical component. Whether the function of a mechanical equipment can be brought into full play depends on whether the smooth bearing is appropriate. Smoothness is a necessary condition to ensure the normal operation of the bearing. It plays an important role in improving the bearing capacity and service life. Regardless of the choice of smooth method, smooth in the rolling bearing can play the following effects.

The composition of the oil film increases the touch area and reduces the touch stress. Eliminate conflict heat, reduce the temperature of the bearing working surface, and avoid burns. From dust, rust, corrosion effect. Reduce the conflict between metals and slow down their wear. To ensure that the rolling bearing can touch stress in high frequency, a long time to normal operation, extend the fatigue life.

Therefore, the correct smoothness is very important for the normal operation of the rolling bearing. The content of smooth description of rolling bearings mainly includes: the judgment of reasonable smooth method, the correct selection of smooth agent, the quantitative calculation of smooth agent dosage and the judgment of oil change period. Rolling bearing smoothness can usually be divided into oil smoothness, grease smoothness and solid smoothness according to the type of smoothing agent used.

Among them, oil smooth has a wider temperature application range than other smooth methods, and is more suitable for bearings operating under high speed and high load conditions. Because oil smooth also has the advantages of equipment protection and smooth agent replacement convenience, and conflict pairs such as gears in the system can be smooth together, so far, the use of oil smooth bearings is more widespread.

Grease smooth has the advantages of simple sealing equipment, low repair cost and low cost of smooth grease. It is widely used in bearings operated at low speed, medium speed and medium temperature. In particular, the availability of anti-wear additives in these years has improved the smooth function of the grease and made it more widely used. If the use of oil smooth and grease smooth can not meet the smooth conditions required by the bearing, or can not meet the specific operating conditions, you can use solid smooth agent, or try to improve the smooth function of the bearing itself.
