Abstract

The invention discloses an axial eccentric anti-loose fixing structure. The axial eccentric anti-loose fixing structure comprises a rotor, an inner cavity, and an eccentric cover, an axial member is mounted in the rotor through a spline structure, a shaft lever is welded to one end of the axial member, a thread hole is formed in the shaft lever, the inner cavity is formed in the axial member, a clamping groove is formed in the inner cavity, a bolt is fixedly mounted in the axial member through the thread hole, a screw head is welded to one end of the bolt, the eccentric cover is mounted at thebottom of the screw head, and the rotor and the shaft end surface are positioned and locked through the eccentric over and the bolt. According to the axial eccentric anti-loose fixing structure, thecentripetal central point can be offset through combination of eccentric design of the bolt and the axial member, the centripetal force borne by the bolt and the rotor is different, the bolt rotates and is screwed at the high speed along with the rotor, loosing of the bolt is prevented, the breakdown due to the failure of rotor positioning is reduced, the maintenance efficiency of the device is reduced, the service life of the device is prolonged, and the practicality of the device is improved.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to an axial eccentric anti-loosening fixing structure. Background technique [0002] In the structural design of the pump, the rotating parts such as the rotor or the impeller and the end face of the rotating shaft are usually locked by threads. The threads may become loose during long-term operation. At this time, an eccentric anti-loosening fixing method is needed to solve the problem. This problem guarantees the correct axial displacement of the rotating parts. [0003] The defects in the existing axial eccentric anti-loosening fixing structure are: [0004] 1. Circumferential rotation generates centripetal force, which may cause the screw head to loosen during the rotation process, which will cause failure of rotor positioning and failure; [0005] 2. The thread may become loose during long-term operation, and it needs to be stopped for inspection. [0006] For this reason, we ...
