Description

Technical Field

[0001] The utility model relates to the technical field of motor front end cover end face detection, in particular to a motor front end cover end face runout detection device. Background Art

[0002] The end face detection of the motor front end cover is a relatively important link in motor detection. It will affect the performance and service life of the motor. The commonly used motor front end cover end face runout detection is to place the motor horizontally, but there is a problem that needs attention. That is, since the motor is placed horizontally when it is measured, the rotor will sink under the action of its gravity, causing its axis to deviate from the center position (the theoretical deviation value is half of the radial clearance of the bearing used), and the end face of the motor front end cover may also sink. When measuring the end face of the motor front end cover, it may cause measurement value errors, which brings certain difficulties to the final result judgment and even leads to misjudgment. For this reason, we propose a motor front end cover end face runout detection device to solve the above problems that may arise. Utility Model Content
