On spherical roller bearing and the cause of injury
Clicks:46073 Date:1-15
In the process of using spherical roller bearing, improper use or improper maintenance, it is very likely that spherical roller bearing will be damaged. Spherical roller bearing should be lubricated well and properly obstruct sundries and moisture, indicating that the oil seal should not be worn. However, it is best to open the spherical roller bearing spherical roller bearing check box, and periodically check the oil seal, check the roller bearing near spherical oil seal condition, to ensure that they are adequate to prevent corrosion of hot liquid or gas or liquid infiltration along the axis of the spherical roller bearing, oil seal ruoyi wear should be replaced as soon as possible. High temperature spherical roller bearing often said in unusual circumstances, high temperature is also harmful to the spherical roller bearing spherical roller bearing lubricant, sometimes overheating can be attributed to the spherical roller bearing spherical roller bearing lubricant, if long-term operation in more than 125 degrees Celsius temperature, will reduce the spherical roller bearing life.
Spherical roller bearing high temperature damage include: lack of lubrication or excessive lubrication, lubricant contains excessive load, spherical magazine, roller bearing damage, lack of space, and oil have high temperature friction and so on. Spherical roller bearing rolling body and the inner and outer raceway surfaces are subjected to periodic pulsatile loads, thus the periodic changes of contact stress. When the number of stress cycles reaches a certain value, the fatigue exfoliation is produced on the working surface of the rolling body or the inner and outer raceways. If the load of spherical roller bearing is too large, this fatigue will be aggravated. In addition, spherical roller bearing installation is not correct, shaft bending, also produce raceway exfoliation phenomenon. The fatigue exfoliation of the spherical roller bearing raceway reduces the operation precision of the shaft and causes the mechanism to vibrate and noise. The metal of the cage is attached to the roller, the possible reason is that the roller is stuck in the cage or is not lubricated.
The spherical roller bearing of the burn raceway and rolling body temper on. The cause of the burn is usually insufficient lubrication, the quality of the lubricating oil is not conformed to the requirement or deterioration, and the assembly of spherical roller bearing is too tight. Uneven pits appear on the contact surface of the raceway and roller of spherical roller bearing, indicating that spherical roller bearing produces plastic deformation. The reason is that the local stress of the spherical roller bearing under the static load or impact load exceeds the yield limit of the material, which usually occurs on the low speed rotating spherical roller bearing. The reason for cracks in the spherical roller bearing seat ring may be the tight fitting of spherical roller bearing, the loosening of spherical roller bearing, the loosening of the foreign or inner rings, the deformation of the containment parts of spherical roller, and the poor surface processing of the installation. The spherical roller bearing holder fragmentation is due to the lack of spherical roller bearing lubrication, the crusher of the rolling body, the skew of the seat ring, etc.
