Surface bearing installation principle
The plane bearing mainly bears the axial load in the assembly, and it is widely used. Although the plane bearing installation operation is relatively simple, but in actual maintenance, there are still frequent errors, that is, the bearing's tight ring and loose ring installation position is not correct, the result of which makes the bearing lose its function and the journal is quickly worn.
The figure shows that the tightening ring is installed on the end face of the stationary part, that is, wrong assembly. The inner ring of the tightening ring and the journal are in transition coordination. When the shaft rotates, drive the tightening ring and friction with the end face of the stationary part. When the axial force (Fa) is applied, the friction torque is greater than the internal diameter matching resistance.
