Gear Shaft Removal Tool

Abstract

The invention discloses a gear shaft system dismounting tool. The gear shaft system dismounting tool comprises a shaft positioning system and a gear positioning system, wherein the gear positioning system comprises a rotary disc and a slide block; the rotary disc forms a guide rail; a distance between the starting point of the guide rail and the circle center is greater than that between the final point of the guide rail and the circle center; the starting point and the final point are on different radiuses; the slide block forms a guide block; the guide block is in sliding fit with the guide rail; the shaft positioning system comprises a pressure head and a pressure cylinder, wherein the pressure head abuts against the shaft in the gear shaft system from one end; and a piston rod of the pressure cylinder abuts against the shaft from the other end. According to the gear shaft system dismounting tool disclosed by the invention, the rotary disc rotates, so that the guide block matched with the guide rail drives the slide block to move in the radial direction of the rotary disc; when the gear shaft system is dismounted, the shaft positioning system is used for positioning the shaft, and the rotary disc rotates to regulate the position of the slide block, so that the slide block abuts against the end surface of the gear block; and finally, the shaft positioning system applies axial force to the shaft, so that the shaft and the gear are dismounted.

Description

technical field [0001] The invention relates to a dismantling aid, in particular to a gear shaft dismantling tool. Background technique [0002] The gear shaft system is one of the core components of the gearbox. The quality of gears, synchronizers and bearings directly affects the power transmission performance and running noise of the entire gearbox. The gap fit between the gear and the output shaft, the spline connection between the synchronizer and the output shaft, the interference fit between the bearing and the output shaft, the maximum press force of the synchronizer and the bearing can reach 40KN during assembly. [0003] When the gear shaft system breaks down during assembly and complete machine testing and needs to be repaired, there are no safe, convenient and effective measures for dismantling. [0004] Most of the gears and shafts are clearance fit, which can be reused after disassembly. If the tools are not disassembled effectively, the entire shaft system wi...

AI Technical Summary

Problems solved by technology

[0004] The gap between the gear and the shaft is mostly used, and it can be reused after disassembly. If the tool is not disassembled effectively, the entire shaft system will be scrapped, resulting in waste of parts and increasing production costs.
