Multi-purpose bearing extractor

Abstract

The invention discloses a multi-purpose bearing extractor. According to the multi-purpose bearing extractor, an internal shaft sleeve is arranged on the inner side of an external shaft sleeve, a screw rod is arranged on the inner side of the internal shaft sleeve, and a tip is arranged at the bottom end of the screw rod; the internal shaft sleeve is mounted in the external shaft sleeve in a sliding manner, the screw rod is mounted in the internal shaft sleeve through threads, the outer end of the external shaft sleeve is connected with a connecting sleeve, and the connecting sleeve is connected and mounted on external threads of the external shaft sleeve through threads; a base is arranged on the bottom end of the connecting sleeve, steps are arranged on the upper end of the base, flanges are arranged on the steps, three groups of external pull rods are arranged on the periphery of the flanges, three groups of internal pull rods are arranged in the middle of the external shaft sleeve, three groups of pull hooks are arranged on the lower ends of the flanges, the upper ends of the internal pull rods are mounted and connected on the external shaft sleeve through upper connecting pins of the internal pull rods, and the lower ends of the internal pull rods are connected and mounted on the pull hooks through lower connecting pins of the internal pull rods. The multi-purpose bearing extractor is simple in structure, reasonable in design, complete in function, and convenient to use.

Description

technical field [0001] The invention relates to a tool for dismantling a bearing, specifically a bearing dismantling tool. Background technique [0002] Bearings are commonly used accessories in the machinery industry. They are installed on the wheel shaft or bushing by the inner or outer edges according to the needs. Since the installation clearance of the bearing is a tight fit and is blocked by the shell or various conjoined parts, It is extremely difficult to disassemble. Currently, the existing dismantling tools have single functions and unreasonable structures, especially the control of the claws is almost zero. Because the claws of the puller are messy and up and down, it brings a lot of inconvenience to the disassembly work. Originally, the workload of one person requires two people to cooperate, which is not only labor-intensive and time-consuming, but also easily causes industrial accidents. Contents of the invention [0003] Therefore people have great demand t...
