Abstract

The invention discloses a household appliance motor comprising bearing outer covers, bearings, bearing inner covers, a support installed on a stator and provided with bearing chambers, a shaft penetrating through the stator and the support, and movable gaps arranged between outer ring end faces of the bearings and inner spigots of the bearing outer covers. The bearing outer covers, the bearings and the bearing inner covers are sequentially installed on the shaft; each bearing is located between one bearing outer cover and one bearing inner cover; a plurality of fixing pieces for fixing the bearings are formed on the peripheries of the bearing chambers in an integrated mode; the support comprises a flat-plate-shaped substrate and two supporting arms extending along the axial direction of the shaft from two ends of the substrate and fixed on the stator, and the bearing chambers are located in the middle of the substrate and concave inwards. The movable gaps are arranged between the outer ring end faces of the bearings and the inner spigots of the bearing outer covers, movable space is provided for the bearings, friction between one bearing and the other bearing is not prone to occurrence, the temperature of the motor cannot be exceedingly high, and service life of the motor can be prolonged.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a household appliance motor with high operating reliability. Background technique [0002] Electric motors are widely used in industrial production and daily life, and are one of the more important tools. Since most electric motors need to run continuously for a long time, higher requirements are placed on the production quality of electric motors. For most existing asynchronous motors, an important factor affecting the service quality of the motor is the operating temperature of the bearing. If the operating temperature of the bearing is high, the bearing is very easy to be damaged. And the electric motor on the market needs to locate the bearing during routine assembly and production at present, often need to be installed in the inside of the bracket with the special supporting limit plate in this positioning bearing process, and blocks the bearing and prevents from shifting in ...
