Description

Technical Field

[0001] The utility model relates to the technical field related to motor jump test, in particular to a motor jump test tool. Background Art

[0002] In the motor production process, the vibration of the rotating body is a critical parameter. If the vibration value is too large, the motor will vibrate, which will further increase the wear of the rotating body and affect the service life of the motor. Therefore, it is necessary to perform motor vibration testing.

[0003] After massive searches, it was found that the prior art announcement number is CN207113754U, which discloses a motor shaft center hole radial runout measurement tool with a simple structure and easy operation. The tool includes a fixture for clamping the motor shaft, and the motor shaft and the fixture form an axial limit and circumferential rotation connection. The tool also includes a cylindrical detection block connected to the center hole of the motor, and a dial indicator is set on the side of the detection block. The end of the measuring head of the dial indicator is against the surface of the detection block. In the above scheme, the detection block is fixedly connected to the center hole, and the motor shaft is rotated one circle. The radial runout of the detection block is measured using a dial indicator to indirectly measure the radial runout of the center hole. It is simple and convenient.

[0004] In summary, the existing testing method is generally to directly contact the motor rotating body with the dial indicator, but this method may cause damage to the rotating body during the test, and the adjustment of the horizontal position of the dial indicator is more troublesome.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a motor vibration test tooling to make it more valuable for industrial use. Utility Model Content
