[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is commonly used as a reduction gear between a prime mover and a working machine. It matches speeds and transmits torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

Since the wear and leakage mostly occur at the joint surface of the housing, it is necessary to screen out the gaps at the joint surface of the reducer housing for repair during inspection. However, when inspecting the reducer housing, it is necessary to frequently move it to the inspection device, which is not only laborious but also affects the inspection efficiency.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
