This part of the process is the main thrust angular contact ball bearing overhaul process procedures, the repair industry is different from the main symbol of the locomotive manufacturing industry. Bearing into the repair process can continue to use, how to meet the requirements, will be this part of the process to solve the central problem.

Before cleaning, check the grease to maintain the basin to identify and judge the current fuel supplement the effectiveness of the oil system. Second, check the physical and chemical state of the fat, to see whether the fat one thousand, hardening, caking, the analysis of the oil, thinning, discoloration and other deterioration of the situation, to determine and judge the grease aging reasonable replacement cycle, adjust the oil change intervals and oil fill systems.

Bearing cleaning is a necessary part of recovery thrust angular contact ball bearing cleanliness and check the measurement of the bearing parts. Before cleaning to try to erase the old dirty grease, be careful not free to rotate the bearing during operation, in order to avoid the process of disintegration into the impurities strain rolling face of the person; moving bearing light light up, to prevent bruising.

Insist on the use and maintenance of the principle of combining operators bearing routine maintenance work to do Miyoshi (control good use, maintenance), the four (will maintenance checks, troubleshooting), understand (understand the structure, to understand principles, understand the performance). A variety of bearing the operator (driver), must be trained to achieve this thrust angular contact ball bearings operating level should have known, will be asked to obtain an operating permit, after passing the examination, before taking.

Strict implementation of routine maintenance (maintenance) and maintenance (servicing) system on a regular basis. Routine maintenance: the operator in each class as usual for maintenance, including the check in front of the class; class, pay attention to check the thrust angular contact ball bearings is functioning properly; classes after cleaning, maintenance, and found hidden in a timely manner to exclude.
