A motor output shaft concentricity detection device

Abstract

The inventio provides a motor output shaft concentricity detection device. The device comprises a detection mechanism and an execution mechanism; a detection mechanism is arranged on the detection mechanism in a sliding cooperative way; in the normal revolving process of the output shaft, the revolving of the concentric output shaft cannot produce an elliptic motion trajectory, when the output shaft produces the eccentricity, a shrinkage block moves since the elliptic trajectory motion causes the contacting with an arc resisting plate, and the eccentricity can be displayed on an arc plate through an adjusting connecting rod, thereby facilitating the observation of the detection personnel; the problems that the tiny eccentricity of the motor output cannot be detected since the existing detection device is complex in operation, and the detected output shaft eccentric degree cannot be marked, the detection effect is unsatisfactory, a large amount of detection error is existent, and the motor has the safety loophole that the output shaft frequently fractures in the later use process can be solved.

Description

technical field [0001] The invention relates to the technical field of shaft detection, in particular to a concentricity detection device for an output shaft of a motor. Background technique [0002] The function of the motor is to convert electrical energy into mechanical energy. During the energy conversion process, the output shaft is equipped with a pulley or coupling, and then the torque is transmitted through the belt or coupling to drive the equipment to run and do work; but the motor is interrupted during the working process. Shaft failures occur from time to time, and the fracture locations are basically concentrated at the root of the shaft extension, the root of the bearing position, and the web end of the web shaft. [0003] Usually, when the output shaft of the motor itself is installed, it is not concentric with the mounting hole of the motor casing, so that the motor bearing is subjected to excessive radial load during load, which eventually leads to metal fat...

AI Technical Summary

Problems solved by technology

[0006] The present invention can solve the problem that the operation of the existing detection device is complicated, the small eccentricity of the output shaft of the motor cannot be detected, and at the same time, the degree of eccentricity of the output shaft after detection cannot be marked, resulting in unsatisfactory detection results and a large number of detection errors, which lead to the failure of the motor in the later stage. During use, there are often safety hazards such as output shaft breakage.
