Quick damage avoiding dismantling tool for bearing

Abstract

The invention discloses a quick damage avoiding dismantling tool for a bearing. The tool comprises a supporting mechanism, a heating mechanism and a removing mechanism; the supporting mechanism is arranged on a main shaft in a sleeving mode so as to support the bottom surface of a to-be-dismantled bearing; the heating mechanism is used for heating the to-be-dismantled bearing to enable the inner ring of the to-be-dismantled bearing to expand to generate a preset width clearance with the surface of the main shaft; and the removing mechanism is used for driving the supporting mechanism to drivethe to-be-dismantled bearing to slide along the axial direction of the main shaft to be removed from the main shaft. According to the tool, the supporting mechanism provides stable support for the to-be-dismantled bearing, then the to-be-dismantled bearing is heated through the heating mechanism to enable the inner ring of the to-be-dismantled bearing to expand to generate an obvious clearance with the surface of the main shaft, and finally, the to-be-dismantled bearing is removed from the main shaft in a sliding mode by means of the driving action of the removing mechanism. Compared with theprior art, the tool can effectively prevent the main shaft or the bearing from being damaged during the removing process, and meanwhile, the heating mechanism enables the inner ring of the to-be-dismantled mechanism to be quickly heated and expanded, the whole dismantling process is convenient and fast, the maintenance efficiency is improved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tooling, in particular to a quick and damage-free removal tooling for bearings. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] Tooling (the abbreviation of tooling fixture) is an important component of mechanical equipment, and refers to the general term for various tools used in the manufacturing process. There are many types of tooling, generally including fixtures, molds, tools, auxiliary tools, fitter tools, station equipment, fixtures, etc., which are used to clamp workpieces, limit the shape and size of production objects, cut metal materials, connect tools and machine tools , fitter work, storage of production objects in the workplace or warehouse, inspection or manufacturing during production, etc. [0004] The installation and disassembly of large mechanical equipment is inseparable from too...

AI Technical Summary

Problems solved by technology

Since the bearing assembly adopts a tight fit between the bearing and the shaft, and the size of the main shaft and the bearing is huge, the disassembly process of the bearing is difficult

[0005] In the prior art, for the dismantling of the main shaft and bearing on the wind power generator, it is generally lubricated by adding a large amount of lubricating oil in the gap between the inner ring of the bearing and the surface of the main shaft, and then using a linear motor to drive the bearing, and finally the bearing Detached from the main shaft, this disassembly method is inefficient, time-consuming and laborious, and due to the long-term interference assembly of the bearing and the main shaft, it is difficult to remove the bearing smoothly even after lubricating with lubricating oil. In addition, the inner ring of the bearing and the surface of the main shaft The long-term accumulation of impurities between the gaps, the influence of manufacturing errors and installation errors, during the dismantling process of forcibly pulling out the bearings, it is easy to cause surface damage to the bearings or shafts, or even scrap them, resulting in huge economic losses and high maintenance costs

[0006] Therefore, how to conveniently and effectively realize the dismantling of the main shaft and the bearing, to avoid damage to the main shaft or the bearing during the dismantling process, and to reduce the maintenance cost is a technical problem faced by those skilled in the art.
