Measuring device for model selection of motor shaft assembly gasket

The invention discloses a measuring device for model selection of a motor shaft assembly gasket. The measuring device for model selection of the motor shaft assembly gasket comprises an outer shaft sleeve, a measuring structure fixedly arranged on the outer shaft sleeve, and a positioning moving structure arranged on the outer shaft sleeve. The positioning moving structure at least comprises a limiting clamping part arranged on the outer shaft sleeve in the circumferential direction of the outer shaft sleeve, and a moving distance measuring part movably arranged on the outer shaft sleeve in the axial direction of the outer shaft sleeve. One end, far away from the outer shaft sleeve, of the limiting clamping part is provided with a limiting hook claw of which the distance in the radial direction can be changed, and the moving end of the moving distance measuring part is in contact connection with the measuring end of the measuring structure. The effects that the measurement mode is convenient, the measurement
