Xiangyang Automobile A3910739 Bearing function
In terms of its function, it should be support, that is, it is used to support the shaft literally, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood as it is used to fix the shaft. The automatic selection of bearings is included. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. The motor cannot work at all without bearings. Because the shaft may move in any direction, and the motor is required to only rotate when it is working.
Causes of heating of rolling bearings and their elimination methodsLow bearing accuracy: select bearings with specified accuracy grades.
The spindle is bent or the box hole is not concentric: repair the spindle or box.
Poor lubrication: use the lubricating material of the specified brand and clean it properly.
Low assembly quality: Improve assembly quality.
Bearing inner and outer shell running ring: replace the bearing and related wear parts.
Axial force is too large: cleaning and adjusting the sealing ring gap between 0.2mm and 0.3mm, correcting the diameter of the impeller balance hole and verifying the static balance value.
Bearing damage: replace the bearing.
