This part of the process is the main thrust angular contact ball bearings overhaul process is the repair industry different from the main locomotive manufacturing industry flag. Bearing into the repair process can continue to use, how to meet the requirements, will be the center part of the process to solve the problems.
1. Prior to cleaning, first check the grease retains basin to determine and judge the current refueling, the effectiveness of the system up the oil. Second, check the grease of the physical and chemical state, to see whether the fat one thousand, hardening, caking, condensate oil, thinning, discoloration, deterioration, and to determine and judge the grease aging reasonable replacement cycle, adjust the oil change intervals and fill oil regime.
2. Bearing cleaning to restore the thrust angle contact ball bearings cleanliness and necessary part of the bearing parts check measurement. To try to erase the old dirty grease before washing, careful not to rotate freely bearing strain to avoid the disintegration of impurities into the scroll face during the operation; moving bearings to gently to prevent bruising.
Insist on the use and maintenance of the combination of the principles of, day-to-day maintenance of the operator in bearing do Miyoshi (tube with good maintenance), four will be (will be used, will be maintenance checks will troubleshoot), three understand (understand the structure, to understand the principle of to understand performance). Various bearings operator (driver), must be trained, should reach the technical level of the thrust angular contact ball bearings operating knowledge, will be asked to obtain an operating permit, after passing the examination, before taking a post.
To strictly implement the day-to-day maintenance (maintenance) and maintenance (servicing) system on a regular basis. Routine maintenance: the operator in each class as usual maintenance, including classes before the examination; class attention to check whether the normal operation of the thrust angular contact ball bearings; classes after cleaning, maintenance, found hidden in a timely manner to exclude.
Rational planning principles of scientific maintenance, Axial angular contact ball bearings to maintain focus, reflected in improve the quality of repair work, reduce downtime, improve the bearing operating rate. To do so it must be reasonable and planning, preventative planned maintenance, while paying attention to the scientific method of maintenance in order to achieve the maximum efficiency.
