How to extend the life of the rotor bearing?

Rotor bearings are one of the frequently replaced parts of the impact crusher. How to extend the life of the rotor bearing? The following Asian fluid network small series is explained in the following three aspects.

First of all, to choose the appropriate model and specifications, the common column-center spherical rolling bearing has strong pressure resistance, high wear resistance and good self-aligning. It is more suitable as a rotor bearing for impact crusher, and its service life is long and its average life is 10,000 hours or so.

Secondly, it is necessary to adjust the force of the impact crusher rotor bearing. The force of the rolling bearing depends on the impact force of the broken rock of the rotor and the supporting force of the bearing seat. Moderate adjustment of the flexibility of the bearing seat will reduce the rolling pressure of the bearing to a certain extent, and the user can pass the bearing seat. A rubber sheet is added in the middle of the bracket to increase the flexibility of the bearing seat, thereby damping the bearing's rotational pressure, reducing bearing wear and prolonging the service life of the rotor bearing.

Finally, it is necessary to ensure that the rotor balance accuracy is within the appropriate range. The quality of the counter crusher rotor and the plate hammer is very large. If the plate hammer is eccentric when the rotor rotates due to quality error or misalignment, the bearing rotational pressure will be increased, and the crusher will generate abnormal vibration and damage other zeros. component. Therefore, when installing the hammer, the staff must strictly follow the instructions on the drawings to reduce the error as much as possible, so that the rotational pressure of the rotor bearing becomes smaller and the service life is prolonged.
