Detailed Description

As shown in fig. 1 and 2, an air bearing thrust plate tool comprises a cylindrical hollow sleeve seat 1, a shaft rod 2 coaxially arranged in the sleeve seat 1 in a penetrating manner, a reducer pipe 3 and a stop wrench 4 respectively arranged on the upper surface and the lower surface of the sleeve seat 1 in a penetrating manner, external threads are arranged on the outer surface of the shaft rod 2, internal threads are arranged on the inner side wall of the sleeve seat 1, the shaft rod 2 is rotatably connected with the sleeve seat 1 through the external threads and the internal threads, and a cap nut 5 is arranged at one end, away from the reducer pipe 3, of the shaft rod 2.

When the device works, the shaft lever 2 vertically penetrates into one end of the thrust bearing, the pipe diameter of the reducer pipe 3 is amplified, the amplified reducer pipe 3 is locked by rotating the braking spanner, the shaft lever 2 is rotated by rotating the cap nut 5, and the thrust bearing is ejected; the utility model discloses can prevent because the footstep bearing damage that the installation or dismantlement caused, extension footstep bearing life-span.

As shown in fig. 1 and 2, a braking through hole 11 is formed between an inner side wall and an outer side wall of the sleeve seat 1, a stopping rod 41 is arranged in the braking through hole 11, the stopping wrench 4 is in driving connection with the stopping rod 41, a stopping groove 42 is formed at the bottom of the reducing pipe 3, and after the reducing and amplifying of the reducing pipe 3, the stopping wrench 4 drives the stopping rod 41 to rotate and be inserted into the stopping groove 42 for locking; in this embodiment, after the reducing pipe 3 is enlarged, the stop rod 41 is screwed into the stop groove 42 through the stop wrench 4 to lock the enlarged reducing pipe 3, so that the reducing pipe 3 is prevented from following up when the shaft rod 2 rotates, the damage of the thrust bearing caused by installation or disassembly can be prevented, and the service life of the thrust bearing is prolonged.

As shown in fig. 1 and 2, the reducer pipe 3 includes a left reducer block 31 and a right reducer block 32 which are arranged in a semicircular shape, the left reducer block 31 and the right reducer block 32 are arranged in an opposite manner, and the left reducer block 31 and the right reducer block 32 surround to form the reducer pipe 3; in this embodiment, the contact surfaces of the left reducing block 31 and the right reducing block 32 repel each other or attract each other, so that the diameter of the reducing pipe 3 is enlarged or reduced.
