The most important parts of the bearing are the first choice of the bearing. If the quality of the bearings is to improve the quality of the bearings during the production process, the China Bearing Network told you that it mainly improves the quality requirements of the bearings in production in production.
1. The motor assembly site should be kept clean. After the bearing is painted with fat, there is no dust on the scene. The parts after the bearing must be assembled by strict inspections, and any tiny link cannot be ignored. For example, the shaft shoulder at the coordination of the shaft and the bearing, if the roots have no rounded corners, it is easy to produce stress concentration during operation and twist the shaft here; The amount of transmission of the inner set is super worse, or the bearings cannot be in place.
2. Dynamic balance quality is an important factor that affects the life of the bearings. The larger the motor, the higher the speed, and the higher the quality requirements of the balance of the balance.
3. The components related to the bearing, the coa of the machine seat, end cover, rotor, bearing, and inner and outer cover of the bearing, and ensure that it should not be destroyed by the deformation of the components during the operation of the motor. Large -sized parts, such as machine seats, end covers, etc., must be processed.
4. The processing accuracy of parts related to bearings should be improved. Because the processing accuracy of the bearing itself is very high, and when the bearings are matched with related components, the tiny overweight volume will cause the bearing damage. Practice verification, the use of CNC machine tools with a "fixed -dimensional tool" processing bearing room can control the tolerance zone within a range of about 0 and 02mm. The roughness of the coordination with the inner and coat circle should also be improved as much as possible. Otherwise, after the "knife peak" processing of gold processing after multiple disassembly, the original design of the original design will also change.
5, the lubricating fat should be appropriate, otherwise the bearings should be heated. If the ambient temperature is higher than 40 ° C, you should choose a high degree of stitching fat. Conversely, the acupuncture degree should be used low or special lubrication.
It is inevitable when faulty in the use of bearings. If the quality of the bearings is improved, it depends on how the bearing is used. We can also understand through the above five aspects when choosing a bearings to refer to the quality of the bearings.
