Motor

Abstract

The invention belongs to the technical field of motors, and particularly relates to a motor. The embodiment of the invention aims to solve the problem that the bearing is difficult to detach from the driving shaft due to the interference fit between the inner ring of the bearing and the driving shaft in the prior art. According to the motor provided by the embodiment of the invention, the housing encloses to form the accommodating channel, one end of the accommodating channel is covered with the first end cover, and the other end of the accommodating channel is covered with the second end cover; a bearing hole is formed in the second end cover, the bearing is arranged in the bearing hole, and the rotating end of the driving shaft is arranged in an inner ring of the bearing in a penetrating mode; the driving shaft is sleeved with an abutting-against pipe, one end of the abutting-against pipe abuts against the side face, facing the containing channel, of the bearing inner ring, and the other end of the abutting-against pipe extends out of the bearing hole. When the bearing is disassembled, the abutting pipe located outside the bearing hole is knocked, the abutting pipe abuts against the bearing inner ring, then the bearing inner ring is separated from the driving shaft, separation between the bearing inner ring and the driving shaft is easy, and the disassembling difficulty of the bearing is reduced.

Description

Technical field [0001] Technical Field The present invention relates to an electric motor, in particular, it relates to an electric motor. Background technique [0002] With the increasing popularity of the railway network, rail train has become an important way land transport; which, most of the power from the motor rail train set in the bogie. [0003] In the related art, the motor comprising a housing, a stator, a rotor, a first end cap and second end cap; receiving channel is provided on the housing, a stator disposed on an inner wall of the accommodating channel, a stator disposed around the cavity to rotate the rotor is provided in the rotation chamber; a first end cap disposed at one end of the accommodating channel on the rotor shaft and an output terminal through a first end cap outwardly so as to output power to the drive shaft; a second end cap disposed on the receiving channel the other end, the second end cap is provided with a bearing bore, the bearing disposed in t...
