Puller

Abstract

The invention discloses a puller, comprising: a support gasket system, the support gasket system has a diameter-adjustable installation inner hole, and the installation inner hole can be fixedly matched with the shaft (1); A threaded sleeve (2) arranged outside the shaft (1), the threaded sleeve (2) has an external thread structure, and the end of the threaded sleeve (2) can be positioned with the support gasket system Contact; claw support frame system, the claw support frame system includes a sleeve rotating nut (3) matched with the external thread structure and a claw axially positioned with the sleeve rotating nut (3) A support frame (4), the claw support frame (4) has a ring member claw (8) capable of hooking the ring member (12) on the shaft (1). The above-mentioned puller only needs to adopt the threaded sleeve that can be sleeved on the outside of the shaft to realize the disassembly of the ring part without being limited by the length of the shaft, thus improving the versatility of the puller.

Description

technical field [0001] The invention relates to the technical field of pulling equipment, in particular to a puller. Background technique [0002] There are mainly two types of existing pullers, one is three-claw type or two-claw type (hereinafter collectively referred to as "claw type"), and the other is cylinder type, but the principles of the two types of pullers are the same. That is to say, the tip of the central bolt is pushed against the end surface of the shaft, the tip of the three claws (or two claws) or the auxiliary gasket is installed on the end surface of the tension bearing, and the bearing is separated from the shaft by rotating the central bolt. It can be used to remove ring parts such as bearings or gears on the shaft of the engine gearbox or gearbox. [0003] Although the structure of the claw or barrel puller is simple and easy to operate, because it must push the tip of the center bolt against the end face of the shaft, the bearings that can be removed ...

AI Technical Summary

Problems solved by technology

[0003] Although the structure of the claw or barrel puller is simple and easy to operate, because it must push the tip of the center bolt against the end face of the shaft, the bearings that can be removed will be limited by the length of its own claw (or barrel). The only way to disassemble the bearing on the longer shaft is to use a large-scale long-jaw (or long-barrel) puller, but there are few pullers with such long claws on the market, which need to be specially customized, thus reducing the number of such pullers. The versatility of the puller
