Bearings are the key parts of mechanical equipment, and the application quality is the first choice of bearings. In the production process, we want to improve the quality of bearings and improve the quality regulations of bearings.

1. The motor installation and construction site should be kept clean. After the bearing is coated with grease, there can be no dust flying on the spot. The parts matched with bearings need to be assembled through strict inspection, and any minute stage can not be ignored. For example, the shaft ring where the drive shaft and the bearing cooperate with each other, if the root is cleared without arc, it is easy to cause stress when running, and the shaft will be broken here. If the Angle is too large, or the grinding process is not timely, the interference quantity of the inner throwing ring needs to be deviated when the suction bearing is installed, or the bearing is not timely, which is the disaster of early damage.

3. The parallelism of bearing related parts -- motor shaft, bearing end cover, motor rotor, bearing inner and outer cover is better, and ensure that it does not have to be destroyed because of the deformation of parts in the operation of the motor. Parts with relatively large specifications, such as motor shafts and bearing end covers, must be conditioned.

4. The processing accuracy of parts related to bearings should be improved. Because the machining accuracy of the bearing itself is very high, and the bearing and the corresponding parts cooperate with each other, the very small interference will cause the damage of the bearing. Practical activity certification, the use of multi-pull CNC lathe with "fixed specification CNC blade", production and processing bearing room can manipulate the tolerance level within the range of 0, 0Am. The torsional roughness of the matching place with the bearing inner and outer ring should also be improved as much as possible. Otherwise, after grinding away the "edge peak" of the gold production and processing through several slope removal, the matching size of the original design scheme will also be changed.

5, the grease should be appropriate, otherwise the bearing should be hot. If the temperature exceeds 40 ° C, choose a grease with a strong needle insertion degree. On the contrary, low needle penetration or special grease should be used
