Bearing is a key part of mechanical equipment. Application quality is the first choice of bearing. If the quality of bearing is to be improved in production, the quality standard of bearing is to be improved.

1. The motor installation and construction site should be kept clean. After the bearing is coated with grease, dust can not fly on the spot. After matching with bearings, parts need to be assembled through strict inspection, and any small 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 type, it is easy to cause the stress field here when running, the shaft will be broken. If the Angle is very large, or the grinding processing is not timely, the interference quantity of the inner throw ring when the suction bearing is installed, then the deviation is needed, or the bearing is not immediately, which is the disaster of premature damage.

3, bearing related parts -- motor shaft, bearing bearing bearing end cover, motor rotor, bearing inner and outer cover better flatness, to ensure that the motor does not have to be destroyed because of the bending of parts during operation. Parts with large specifications and technical parameters, such as motor shaft, bearing bearing end cover, etc., need to carry out heat treatment and quenching.

4. The processing accuracy of parts related to bearings should be improved. Because the processing precision of the bearing itself is very high, and the bearing and the matching parts cooperate with each other, the very small interference will cause the destruction of the bearing. Social practice certification, the selection of numerical control machining center plus "set specifications of technical parameters numerical control blade". The production and processing bearing room can keep the tolerance grade table within the range of 0 and 0Am. The torsional roughness at the matching place with the bearing inner and outer ring should also be increased as far as possible. Otherwise, after grinding away the "edge peak" of gold production and processing based on several slope removal, the matching size of the original system will also change.

5, grease as far as possible, otherwise the bearing should be hot. If the temperature exceeds 40℃, should choose to use a needle into the grease is very strong. On the contrary, low needle penetration ratio or unusual grease should be used
