Abstract
The utility model relates to a magnet ring fixing structure, which comprises a magnet ring fixed on a motor shaft. The two ends of the motor shaft are supported on a bearing, the magnet ring is sheathed on the motor shaft through a through hole arranged on the magnet ring, a radial positioning structure is arranged between the through hole of the magnet ring and the motor shaft, and one end of the magnet ring contacts with the bearing for axial positioning and the other end thereof is provided with a positioning element for axial positioning and fixation. The radial positioning structure arranged between the through hole of the magnet ring and the motor shaft disenables the rotation of the magnet ring in the radial direction of the motor shaft, so as to achieve the effect of fixing the magnet ring. In addition, one end of the magnet ring contacts with the bearing for axial positioning and the other end thereof is provided with the positioning element, and the magnet ring is fixed between the bearing and the positioning element, so as to disenable the reciprocating motion of the magnet ring in the axial direction of the motor shaft and fix the bearing in the axial direction. The magnet ring fixing structure has the advantages of simple installation and operation, reasonable structure, good strength, stable quality and low cost.

The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of to guarantee magnet ring radially can not the rotating of motor shaft, and also makes the axially back and forth play of magnet ring at motor shaft, thereby reaches the fixedly magnet ring fixed structure of the effect of magnet ring.The utility model fitting operation is simple, and is rational in infrastructure, and intensity is good, steady quality, and cost is low.
The technical solution of the utility model is: magnet ring fixed structure of the present utility model, include the magnet ring that is fixed on the motor shaft, wherein the two supports of motor shaft is on bearing, magnet ring is sleeved on the motor shaft by its set through hole, be provided with the radial location structure between set through hole of magnet ring and the motor shaft, and an end of magnet ring and bearing touch and carry out axial location, and the other end of magnet ring is equiped with and carries out axial location and fixing keeper.
Above-mentioned motor shaft is provided with the positioning edge that carries out radial location with magnet ring, the corresponding positioning edge interference fit that is provided with by its through hole and motor shaft of magnet ring.
Above-mentioned motor shaft is provided with the location notch that carries out radial location with magnet ring, the location notch interference fit that corresponding positioning edge that is provided with by its through hole of magnet ring and motor shaft are provided with.
Above-mentioned keeper is a split washer.
Above-mentioned split washer is fixed on the location notch that motor shaft is provided with.
Owing to be provided with the radial location structure, make magnet ring radially can not the rotating of motor shaft, thereby reach the fixedly effect of magnet ring between set through hole of the utility model magnet ring and the motor shaft.In addition, one end of magnet ring and bearing touch and carry out axial location, and the other end of magnet ring is equiped with and carries out axial location and fixing keeper, and magnet ring is fixed between bearing and the keeper, make the axially back and forth play of magnet ring at motor shaft, also make simultaneously bearing axially obtained fixing.The utility model fitting operation is simple, and is rational in infrastructure, and intensity is good, steady quality, and cost is low, is a kind of function admirable, convenient and practical magnet ring fixed structure.
