Abstract

The invention relates to an axial positioning structure. The axial positioning structure comprises an annular slot which is arranged on an outer stretching end of a shaft, two half bushing brushes which are embedded in the annular slot, a sleeve ring which is sleeved outside the two half shaft bushings and an elastic retainer ring, wherein a retainer ring slot which is arranged outside and a limiting step which is arranged inside are arranged on outer circumferential surfaces of the two half shaft bushings; the elastic retainer ring is blocked in a retainer ring slot; and the sleeve ring is arranged between the elastic retainer ring and the limiting step. The axial positioning device solves the technical problem that the current axial positioning structure is difficult to mount and dismount, and a locking gasket is easily damaged in a dismounting process, has a small integral axial dimension, a large bearing axial force, a broad application range, high reliability, and is convenient to mount, change and maintain. The axial positioning device is very convenient to mount, change and maintain as the base structure is simple.

Description

technical field

[0001] The invention relates to an axial positioning structure, in particular to an axial positioning structure for a rotating rotor. Background technique

[0002] Existing axial positioning structures for rotors include lock nuts, circlips, cotter pins, and shaft head screw structures. The size of the lock nut is large, and the thread cannot bear a large axial force, and it must also prevent circumferential rotation; neither the circlip nor the cotter pin can bear large axial force; the shaft head screw structure generally adopts a shaft head screw and A locking washer is used to axially locate the rotor. This structure is difficult to install and disassemble and the locking washer is easily damaged during assembly and disassembly. Contents of the invention

[0003] The object of the present invention is to propose an axial positioning structure for a rotating rotor. It solves some of the disadvantages of existing axial positioning devices.
