Motor assembling tool

Abstract

The invention discloses a motor assembling tool, and belongs to the technical field of machinery. The assembling tool comprises a support assembly and a pulley assembly, wherein the support assembly comprises a first support seat and a second support seat; a dummy shaft is arranged on the first support seat; the dummy shaft extends along a direction from the first support seat to the second support seat; one end of the dummy shaft is used for being fixedly connected with one end of a motor shaft group; the second support seat is used for being fixedly connected with the other end of the motorshaft group; the pulley assembly comprises a track and flatcar; the track is located between the first support seat and the second support seat; the track extends along the length direction of the dummy shaft; the flatcar is glidingly arranged on the track; and the flatcar is used for mounting a motor shell. The motor assembling tool is capable of facilitating the motor assembling.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a motor assembly tool. Background technique [0002] The motor as a whole is divided into two parts, the motor housing and the motor shaft assembly, in which the motor housing is the fixed part of the motor on which a pair of stationary main magnetic poles with DC excitation are installed; the motor shaft assembly is the rotating part of the motor. The part, also known as the armature core, is equipped with an armature winding, which generates an induced electromotive force after being energized, acting as a rotating magnetic field. [0003] In the process of assembling the motor housing and the motor shaft group, there is a magnetic field generated by the permanent magnet in the motor housing, and the armature winding of the motor shaft group moves axially in the motor housing, cutting the magnetic induction The wire generates an electromotive force, and then gene...

AI Technical Summary

Problems solved by technology

[0003] In the process of assembling the motor housing and the motor shaft group, there is a magnetic field generated by the permanent magnet in the motor housing, and the armature winding of the motor shaft group moves axially in the motor housing, cutting the magnetic induction The line generates electromotive force, and then generates another magnetic field. Under the interaction of the two magnetic fields, it is difficult for the motor shaft group to remain concentric with the motor housing

For large motors, during the assembly process of the motor housing and the motor shaft assembly, it is necessary to move at least 2500mm relative to the axial direction, resulting in a greater impact on the motor assembly due to the interaction of the magnetic field
