This part of the process is the main process of the maintenance process of thrust angular contact For Cleaning ball bearing and the main symbol that the repair industry is different from the locomotive manufacturing industry.
Whether the bearing entering the repair process can continue to be used and how to meet the use For Cleaning requirements will be the central problem to be solved in this part of the process.
1. Before cleaning, first check the condition of the oil retention basin to determine and judge the effectiveness of the current refueling and replenishment system. Secondly, check the For Cleaning physical and chemical state of the oil to see whether there is deterioration such as hair loss,
hardening, caking, oil precipitation, thinning and discoloration, so as to determine and judge the rationality of the aging For Cleaning replacement cycle of the oil, and adjust the oil change cycle and oil replenishment system.
2. Bearing cleaning is a necessary link to restore the cleanliness of thrust angular contact ball bearing and check and measure bearing parts. Before cleaning, wipe off the old dirty grease as much as possible.
During the operation, pay attention not to rotate the bearing at will, so as not to damage the rolling For Cleaning working surface by impurities entering during disassembly; Handle the bearing with care to prevent bumping.
Adhere to the principle of combination of use and For Cleaning maintenance, and the operators shall do three things (manage, use and maintain well), four skills (use, maintenance, inspection and troubleshooting), and three understandings (structure, principle and performance).
The operators (drivers) of various bearings must be trained to meet the technical level of thrust For Cleaning angular contact ball bearing operation. They should know and be able to meet the requirements. They can take the post only after passing the examination and obtaining the operation certificate.
The system of daily maintenance (maintenance) and regular maintenance (repair) shall be strictly implemented. Daily For Cleaning maintenance: the operator carries out maintenance as usual every shift, including pre shift inspection;
During the shift, pay attention to check whether the thrust angular contact ball bearing operates normally; Clean and maintain after shift, and eliminate hidden dangers in time.
Adhere to the principles of reasonable planning and scientific maintenance, and focus on the maintenance of thrust angular contact ball bearings, which is reflected in improving the quality of maintenance work, reducing failure downtime and improving the operation rate of bearings.
To do this, we must make reasonable planning, preventive planned maintenance, and pay attention to the use of scientific maintenance methods to achieve greater efficiency.
