Correct installation steps for bearings
1, using the bearing to install and disassemble special tools
Advanced mounting tools to avoid bearing damage due to improper tooling and handling during installation. For example, when installing the bearing, the staff used the copper rod knock-in method, which easily caused the bearing axial force to be uneven, causing the cage to deform, the rolling element to be damaged, the clearance to become large, and the copper rod during the tapping process. The copper powder flies into the bearing cage, which is easy to cause bearing failure.
2. Check the bearing before installation.
For old bearings, check the ball (column) surface for burrs, scratches, and cracks. Whether the radial clearance and axial clearance of the old bearing are qualified, generally only the radial clearance is measured. For new bearings, first check that the bearing model is correct. Refer to Table 1 for the radial clearance criteria for rolling bearings. For example: Model 6318 deep groove ball bearing, bearing inner diameter of 90mm, its radial clearance range is 0.016 ~ 0.046mm, can also be found that the maximum wear of the bearing is 0.25mm.
3, check the bearing and rotor shaft fit size
When assembling the motor, it is necessary to carefully check the fit size of the bearing and the rotor shaft when the bearing is installed (Table 2). The fit size of the outer ring of the bearing and the end cap hole
