Smooth method of rolling bearing
Rolling bearing is an important mechanical element. Whether the function of a mechanical equipment can be fully utilized depends on whether the INA bearing is smooth or not. Smoothness is a necessary condition to ensure the normal operation of the bearing. It is about improving the bearing capacity and service life of the bearing. Counting has an important effect. No matter which smoothing method is selected, smoothing can achieve the following effects in rolling bearings.
The composition of the oil film increases the touch area and reduces the touch stress. Eliminate the conflicting heat, lower the bearing surface temperature and avoid burns. It has anti-dust, anti-rust and anti-corrosion effects. Reduce the conflict between metals and slow down their wear. Ensure that the rolling bearing can work normally for a long time under high-frequency touch stress, extending the fatigue life.
Therefore, the correct smoothness is very important to the normal operation of the rolling bearing. The content of the smooth description of rolling bearings mainly includes: the determination of a reasonable smoothing method, the correct selection of the smoothing agent, the quantitative calculation of the amount of the smoothing agent and the determination of the oil change interval. Rolling bearing smoothness can usually be divided into three categories: oil smoothness, grease smoothness and solid smoothness according to the types of smoothing agents used.
Among them, oil lubrication has a wider temperature application range than other lubrication methods, and is more suitable for bearings operating under high-speed and high-load conditions. Because oil lubrication also has equipment protection and ease of replacement of lubricants, conflict pairs in the system such as gears can be combined The advantages of smoothness, so until now, the use of oil smooth bearings has been widely used.
Grease lubrication has the advantages of simple sealing equipment, low repair cost and lower lubricating grease cost. It is widely used in bearings that operate at low speed, medium speed and medium temperature. In particular, the appearance of anti-wear additives in recent years has improved the smoothing function of grease and has made grease smoother more widely used. If the use of oil smoothing and grease smoothing fails to meet the smooth conditions required by the bearing, or cannot meet the specific operating conditions, you can use solid smoothing agents or try to improve the smoothing function of the bearing itself.
