Problems solved by technology

Due to the operation error of this method, when the air gap of the motor is large, the center position of the stator and rotor is prone to misalignment, which may cause friction or even collision between the upper and lower plates of the bearing.

Abstract

The invention discloses a bearing protection tool for motor rotor filling. The bearing protection tool comprises a tool body (1) which is cylindrical; an end cover (2) is arranged at the bottom of the tool body (1), fixedly connected with the bottom of the tool body (1) and fixed to the shaft end of a rotor shaft; chamfers (5) are arranged on outer sides of a cylinder, opposite to the end cover (2), of the tool body (1). According to the technical scheme of the bearing protection tool for motor rotor filling, in a motor rotor filling process, the occurrence probability of friction or collision between a rotor and a bearing is lowered and even eliminated under the guidance action of the tool, and the bearing is protected.

Description

technical field [0001] The invention relates to the technical field of auxiliary tooling, in particular to a bearing protection tooling used for filling of motor rotors. Background technique [0002] Motor refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. It generates driving torque as a power source for electrical appliances or various machinery. [0003] The motor is mainly composed of a stator, a rotor and other accessories. When some large and medium-sized motors are performing the rotor filling process, the rotor is generally lifted by a tooling and then horizontally loaded into the stator cavity. [0004] When the motor uses rolling bearings, usually the lower part of the bearing is shrunk onto the corresponding position on the shaft first, and the upper part of the bearing (with cage and roller) is first fixed in the bearing sleeve. When the rotor is filled, the worker adjusts the positio...
