Problems solved by technology

[0003]The existing bearing pressure plate is generally a plate-shaped compression structure, one side of the bearing pressure plate contacts the outer ring of the bearing and compresses the bearing, but the installation of this plate-shaped pressure plate is biased After tilting, there will be an overturning force on the outer ring of the bearing. The overturning force will cause the outer ring of the bearing to deflect with the pressure plate, resulting in incorrect installation of the outer ring of the bearing, resulting in shaft noise, and uneven compression of the outer circle of the bearing. The problem of force deflection will cause the motor shaft to ring and vibrate, which will lead to problems such as unstable operation of the motor, high operating temperature of the bearing, and short life.

Abstract

The invention provides a bearing pressing assembly and a motor comprising the same. The bearing pressing assembly comprises: an outer ring pressing ring, wherein the axial first end face of the outer ring pressing ring forms an outer ring abutting face and is used for abutting against an outer ring of a bearing, and the axial second end face of the outer ring pressing ring forms an outer ring pressure bearing face; and an outer ring pressing plate used for being fixed to a bearing pedestal and providing pressing force for the outer ring pressing ring, wherein an outer ring pressing face is formed on the outer ring pressing plate, the outer ring pressing face makes contact with the outer ring pressure bearing face and provides pressure for the outer ring pressure bearing face, and the outer ring abutting face and the outer ring pressing face are in face-line contact. The pressing reliability of the bearing can be improved, so that the running stability of the bearing is improved, and abnormal sound during running is avoided.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a bearing pressing assembly and a motor including the same. Background technique [0002] The bearing in the motor plays the role of supporting the rotating part of the motor, and the normal and stable operation of the bearing ensures the smooth operation of the motor. The installation accuracy and installation process of the bearing affect the life and smooth operation of the bearing. The bearing positioning of the existing motor is generally the inner ring of the bearing positioned by the shaft shoulder and the retaining ring for the shaft, and the outer ring of the bearing positioned by the wave pad and the bearing pressure plate. [0003] The existing bearing pressure plate is generally a plate-shaped compression structure, and one side of the bearing pressure plate is in contact with the outer ring of the bearing to compress the bearing. However, after the plate-shaped press...
