Problems solved by technology

[0006] In this connection method, first of all, when disassembling the puller, a tool must be used to unscrew the nut out of the puller, so that the puller can be taken out from the main body, and the puller is a common tool, and a lot of waste is wasted when disassembling the puller. The time and efficiency need to be improved; in addition, in this connection method, it is necessary to preset threads on the pull claws, and the pull claws are generally made of relatively hard materials, and it is not easy to process threads, and the cost is high

Abstract

The invention discloses a two-claw puller and a dismounting structure and method for a bearing and a shaft. The two-claw puller comprises a long-strip-shaped supporting plate and two pulling claws, ascrew hole is formed in the middle of the supporting plate, a screw rod is arranged in the screw hole in a threaded fit mode, and through U-shaped openings are formed in the two ends of the supportingplate, and the two pulling claws are in sliding fit with the openings of the supporting plate. When the two-claw puller is disassembled and assembled, only the pulling claws need to be directly pulled out of the openings of the supporting plate, and the disassembling and assembling efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of pullers, and in particular relates to a two-jaw puller, a disassembly structure and a disassembly method of a bearing and a shaft. Background technique [0002] The puller is a commonly used tool in the field of mechanical maintenance, and the puller is a disassembly tool that separates the bearing from the shaft. When in use, use three claws to hook the bearing, and then rotate the ejector rod with a threaded buckle, and the bearing will be slowly pulled out of the shaft. [0003] The three-jaw puller is a tool often used in mechanical maintenance. Mainly used to dismantle damaged bearings axially from the shaft. It is mainly composed of a handle, a screw rod and a claw. Its main dimensions are the length of the claws, the distance between the claws, and the length of the screw to adapt to bearings with different diameters and different axial installation depths. When in use, the top of the screw is ...
