Problems solved by technology

[0004] The motor needs to detect the axial runout of the rotor before leaving the factory. If the axial runout of the rotor is large, the noise of the motor will also be large.
In the past, the axial runout of the motor was detected by starting the motor and listening to the noise generated by the motor to judge whether the axial runout of the motor rotor was qualified. This method relied on the worker's supervisor's feeling and could not make a reliable judgment. necessary to change

Abstract

The invention discloses a motor and a play detection device of an output shaft thereof, which comprise a casing and a speed reducer, wherein a rotor is arranged in the casing, an output shaft of the rotor extends out of the casing, the speed reducer comprises a worm wheel, a casing body and a worm, the worm is arranged at the end part of the output shaft, the worm wheel is connected to the casing body in a rotating way, the casing is fixed on the casing body, the output shaft extends into the casing body, the worm and the worm wheel are matched, the end part of the output shaft is provided with a sleeve of which the outer surface is a spherical face, a positioning component is arranged in the casing body, a hole is arranged on the positioning component, the sleeve is connected to the hole in a rotating way, grooves communicated with the inner wall of the hole are arranged on the positioning component, and a clamping arm is formed between the grooves. When the deviation of the installation position of a body occurs, the installation of the body still can not be influenced even if a certain angular offset exists between the output shaft and the positioning component because the outer surface of the sleeve is the spherical face.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a device for detecting movement of a motor and an output shaft of an automobile window lifter. Background technique [0002] The automobile is provided with an automobile window regulator for raising and lowering the window glass. The main part of the automobile window regulator is a motor. The motor includes a casing and a reducer. The casing is provided with a rotor. The output shaft protrudes from the casing, and the speed reducer includes a worm gear, a casing and a worm, the worm is arranged at the end of the output shaft, the worm wheel is rotatably connected in the casing, and the casing is fixed on the On the housing, the output shaft extends into the housing, and the worm is matched with the worm wheel. [0003] Generally, the part of the output shaft of the motor that extends into the housing is connected to the housing through ball bearings. In this way, the installati...
