Ring fixing structure of motor bearing of washing machine

Abstract

This invention discloses a ring fixing structure for a washing machine motor bearing including a motor shaft fixed at the center of a motor rotor, a bearing connected with the shaft, a spacing ring for limiting the bearing, in which, limiting cams are formed at the bearing on the shaft for clamping the spacing ring, which is a round plane sheet one with the shaft passing through, more than two spacing humps are set on the shaft and the ring fixing structure is processed with a broach cutting on the original shaft to heave the edge of the shaft to clamp the spacing ring.

Description

technical field [0001] The invention relates to a washing machine motor. In particular, it relates to a ring fixing structure of a washing machine motor bearing with simple structure and low manufacturing cost. Background technique [0002] The motor consists of a rotor that is press-fitted to a rotating shaft, and a stator that keeps a certain distance from the rotor to rotate the rotor. [0003] The stator includes an iron core and coils. Wherein the stator core includes a plurality of protruding winding portions and slots formed between the winding portions. The coil is wound around the winding portion of the iron core. The shape and size of each winding part and groove are consistent. When power is applied to the coil of the stator, a magnetic flux will be formed in the gap between the stator and the rotor, and the distribution of the magnetic flux in the gap must be in the form of a sine wave, which is beneficial to the performance and noise of the motor requiremen...

Problems solved by technology

[0007] However, the limit snap ring 4 of the above-mentioned structure is an imported product, and the tariff freight cost is relatively high, and then localization is implemented, but the strength of the domestic product cannot meet the required requirements of the product.
