Bearing dismounting device and dismounting method

Abstract

The invention discloses a bearing dismounting device and dismounting method. The bearing dismounting device comprises a base plate provided with an opening groove, a first mounting hole and a second mounting hole, a first upright post, a second upright post, a pressing plate, a first fastening part, a second fastening part and a jacking mechanism. The first upright post can be mounted in the first mounting hole and is provided with a first adjusting piece; the second upright post can be mounted in the second mounting hole and is provided with a second adjusting piece; the pressing plate is provided with a first connecting hole and a second connecting hole; the first fastening part is arranged on the first upright post; the second fastening part is arranged on the second upright post; and the jacking mechanism can apply pressure parallel to the axial direction of a shaft to the pressing plate, one end of the jacking mechanism can abut against the pressing plate, and the other end of the jacking mechanism can abut against the end face of the shaft. According to the bearing dismounting device, the base plate is in contact with the end face of the bearing to be dismounted for positioning, so that the stress area of the bearing to be dismounted is increased, the bearing to be dismounted is stably stressed, the phenomena of deviation, deflection or loosening and the like are not prone to occurring, then the possibility that workers are injured is reduced, and the safety of bearing dismounting work is improved.

Description

Technical field[0001]The present invention relates to the field of disassembly tools, and more particularly to a bearing removal device and a disassembly method.Background technique[0002]At present, the common tool for bearing disassembly is Rama. Rama is mainly composed of a spiral, screw and claw. When used, the top of the screw is positioned in the center hole of the shaft end, so that the tip hooks the outer ring of the bearing, and the rotary rotary rotation makes the pulling to move away from the axial direction.[0003]Since the Rama is positioned with the center hole of the screw and the center hole of the shaft end, when the bearing to be removed is mounted on the shaft end without the center hole, the positioning accuracy of the mounting clip in the shaft end cannot be guaranteed, causing the bearing along the axial direction. Even if the offset or skew during the moving process, even the claws are loose to the outer ring of the bearing, so that the staff is damaged, and the...

Problems solved by technology

[0003] Since the puller is positioned by the top of the screw and the center hole of the shaft end, when the bearing to be removed is installed on the shaft end without a center hole, the clamping and positioning accuracy of the puller at the shaft end cannot be guaranteed, which will cause the bearing to move along the axial direction. In the process of outward movement, it is easy to be offset or skewed, and even the claws are loose on the outer ring of the bearing, which will cause injury to the staff and reduce the safety of the bearing disassembly work.
