When installing tapered roller bearings, you can use installation tools such as hammers and copper rods to hit the bearings. During the process, the steel rods are pressed against the cage or the cage is directly hit with a hammer, causing the ribs to break. It is mainly reflected in that improper operation causes the bearing cage to withstand abnormal and continuous impact of external force, resulting in the deformation of the cage and the impact of the guide roller on the rib of the inner ring. When the small rib exceeds the impact load that it can bear, brittle fracture occurs, causing Bearing failed.
Installation suggestion:
(1) It is recommended that when installing the bearing, the user can choose an appropriate assembly method such as cold fitting or hot fitting according to the bearing size and operating conditions. When cold installation is adopted, the installation sleeve should be used as far as possible to cooperate with the installation, which can effectively avoid abnormal impact on other parts of the bearing and ensure that the end face and the journal are vertical when the bearing is installed. When the sleeve installation cannot be used on site, the copper rod should be pressed against the inner ring of the bearing, and the hammer should be symmetrically and circularly struck in the diameter direction. .
(2) Improve the installation skills of the installers and operate in accordance with the correct bearing installation requirements to prevent damage to the bearings due to operational errors, especially violent operations.
