It is very important to keep SKF imported bearings and lubrication clean.
Clean the surface of the machine before inspection, and then Key Steps remove the parts around the bearing. The oil seal is a very fragile part, so it needs to be disassembled carefully.
Do not apply excessive force, and then carefully check the oil seal and its surrounding parts. If there are bad symptoms, be sure to Key Steps replace it. The bad oil seal will lead to bearing damage and strict equipment shutdown.
Check the lubricant. Rub a little Key Steps lubricant between your fingers. If there are pollutants, you can feel it, or apply a thin layer of lubricant on the back of your hand, and then seal it for inspection.
Change the lubricant. After draining the old oil, fill in fresh oil if possible and let the machine rotate at low speed for a few minutes. Make the engine oil Key Steps collect residual pollutants as much as possible, and then drain the engine oil. The engine oil is filtered before use.
For grease lubricated bearings, the arbor used when replacing grease should avoid connecting the angle of cotton to any part of the Key Steps bearing, because these residual fibers may wedge between the rolling parts and cause damage, especially for the application of small bearings.
Cover the exposed SKF imported bearings. When inspecting the bearings, do not expose the bearings to pollutants or moisture. If the work is interrupted, the machine shall be covered with oil paper, plastic sheet or similar materials.
If it is possible to clean the naked bearing without disassembly, Key Steps clean it with a brush coated with white spirit, and then dry it with a piece of lint free cloth or blow dry with compressed air (be careful not to start the rotation of the bearing assembly).
Do not clean the sealed cover or dust-proof bearing; Just wipe the outer surface. If the bearing is Key Steps damaged, it needs to be replaced. It is much more economical to replace the bearing during the regular shutdown and maintenance period than the loss of sudden shutdown due to the damage of the array bearing.
This part of the process is the main process of the maintenance process of thrust angular contact ball bearing and the main symbol that the repair industry is different from the locomotive Key Steps manufacturing industry.
Whether the bearing entering the repair process can continue to be used and how to meet the use 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 Key Steps refueling and replenishment system. Secondly, check the 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 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 working surface by impurities entering during disassembly; Handle the bearing with care to prevent bumping.
Adhere to the principle of combination of use and 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 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 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.
