Plane bearing installation method and matters needing attention

by:JNSN     2021-11-04
There are two types of plane bearings, one is a plane bearing with needle rollers, and the other is a plane bearing with balls. Bearings play an important role in the social development of industrial machinery. Bearings are everywhere. How to install plane bearings do you know? If you don’t know, please see below.

The installation method of the plane bearing: The plane bearing mainly bears the axial load in the assembly and is widely used. The installation and operation of the plane bearing is relatively simple, but there will be errors in the actual maintenance. If the tight ring and loose ring of the bearing are installed incorrectly, the bearing will lose its function and the journal will be quickly worn out. The inner ring of the tight ring and the journal are in transitional fit. When the shaft rotates, it drives the tight ring and rubs against the end surface of the stationary part. When the axial force is applied, the friction torque will be greater than the resistance torque of the inner diameter fit, resulting in the tight ring and the shaft. Forced rotation of the mating surface increases the wear of the journal. The correct installation method is to change the position of the loose and tight rings.

Some things should be paid attention to when installing the plane bearing, distinguish the static parts of the mechanism, that is, the parts that do not move, mainly refer to the assembly. Distinguish the tight ring and loose ring of the bearing. According to the inner diameter of the bearing, the difference in bore diameter is 0.1-0.3mm. In any case, the loose ring of the bearing should always rest on the end face of the stationary part.

The above is the installation method and precautions of the plane bearing. For some simple operations, if you do not pay attention, you will make mistakes. We should avoid these mistakes so as not to affect our work.
