Protective device for rotor bearing fault simulation experiment

A protection device for a rotor bearing fault simulation experiment comprises a base, the top of the base is fixedly connected with a U-shaped frame plate, an L-shaped baffle is rotationally connected between the two sides of the middle of the U-shaped frame plate, the middle of the end, away from a rotating shaft, of the L-shaped baffle is fixedly connected with a trapezoidal insertion rod, and an insertion groove is formed in the position, opposite to the trapezoidal insertion rod, of the top of the base. The bearing protection device has the advantages that the anti-collision sponges are arranged on the inner walls of the U-shaped frame plates and the L-shaped baffles, when a bearing is broken, broken parts collide with the anti-collision sponges, protection is achieved, and meanwhile noise can be lowered; when the trapezoidal insertion rod is inserted into the base, the trapezoidal insertion rod is clamped by the limiting block, and the L-shaped baffle is prevented from being bounced off when the bearing
