Description

Motor assembly wave washer detection device that targets in place

Technical Field

The utility model relates to a motor manufacturing technology field, in particular to motor assembly wave washer detection device that targets in place.

Background

In the running process of the motor, the rotor part can displace in different degrees in the axial direction and the radial direction, and the adverse phenomena of noise, vibration and the like of the motor are shown, and axial movement is shown when the axial relative displacement is large.

In the whole motor design process, the thermal expansion factor of the motor material can be considered, a certain gap is reserved in the axial direction, meanwhile, in order to prevent hard contact and disconnection in the axial displacement process, the mode of additionally installing the wave washer is adopted to solve the problem, if the wave washer is not installed in the assembling process or the quality of the wave washer is in problem, axial stop failure can be caused, and the shaft fleeing can be directly shown.

In the final assembly process of the existing motor manufacturing factory, before a rotor is placed in a stator, a corrugated gasket coated with lubricating silicone grease is manually placed in an end cover bearing chamber at the center of the stator in advance, the corrugated gasket is easily leaked and damaged corrugated gaskets are easily placed in the overshoot process, after the final assembly is finished, the process of detecting whether the corrugated gasket is placed in place is also lacked, and the trouble and the labor are wasted when the rotor shaft is simply pulled outwards by hands to confirm the axial movement. And the motor can not be accurately measured at the spot check position, and the axial play amount occupies an important position in the aspects of analyzing the noise of the motor and the like.

Therefore, a tool which can conveniently detect whether the wave washer is in place after the motor is assembled and can accurately measure the axial play amount of the motor is needed to solve the problems.
