Analysis and maintenance and lubrication of SKF imported bearings caused by high temperature

Bearing failures are often due to a variety of factors, all design and manufacturing process factors and SKF bearing failures, and their analysis is not easy to determine. Under normal circumstances, in general, you can consider and analyze factors and internal factors.

The main factors used for adjustment are installation, use and maintenance, maintenance, etc. in line with technical requirements. The mounting conditions are one of the factors that use the bearing is the primary factor that often causes the change in state of the state between the various parts of the package, the operation in the abnormal state and early failure. According to the technical requirements of the installation, use, maintenance and maintenance of SKF bearings, the bearing contact load, speed, temperature, vibration, noise and lubrication status are monitored and checked, and abnormalities are immediately found to find the cause and adjusted back to normal. In addition, the quality of the grease and the surrounding medium, the atmosphere is also very important for analytical testing.

Internal factors mainly refer to structural design, quality manufacturing processes and materials. There are three factors that determine the quality of the bearing.

First, the structural design and advanced will have a longer SKF bearing life. Bearing manufacturing is subjected to multiple processes of forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of the treatment will also affect the service life of the bearing. Affecting the heat treatment and grinding process of bearings, there is often a more direct relationship with the bearing faults associated with product quality. In recent years, studies of the deterioration of the surface layer of the bearing have shown that the grinding process is closely related to the quality of the bearing surface.

The influence of the metallurgical quality of SKF bearing materials is the main factor in the early failure of rolling bearings. With the advancement of metallurgical technology (such as bearing steel, vacuum degassing, etc.), the quality of raw materials has been improved. The proportion of raw material quality factors in bearing failure analysis has dropped significantly, but it is still one of the main factors of bearing failure. The choice of proper or not is still a bearing failure analysis that must be considered.

The main task of SKF bearing failure analysis is based on a large number of background materials, data and failure mode analysis to identify the main factors causing bearing failure, so that targeted improvements can be made to extend the service life of the bearing to avoid unexpected events of the bearing. Early failure.
