Dismounting tool for rolling bearing

Abstract

The invention discloses a dismounting tool for a rolling bearing. The dismounting tool comprises a supporting plate, a screw and a pulling ring; a through hole in which the screw is inserted is formed in the center of the supporting plate; a nut is screwed to the screw and is arranged below the supporting plate; a pulling rod is fixedly arranged on the circumferential wall of the supporting plate; a point hook is arranged at the free end of the pulling rod, wherein the pulling rod is in a shape of a hollow circular ring; a through hole used in match with the point hook is formed in the peripheral wall of the pulling ring. The dismounting tool for the rolling bearing is reasonable in structural design; the pulling ring and the point hook are used in match to effectively prevent slipping between the shaft and the dismounting tool during dismounting, and meanwhile, the frictional force can be decreased, therefore, the probability of damaging a shaft and other spare parts can be lowered down; the pulling ring is of a two-semicircle structure, and two semicircles are connected through bolts, which facilitates the dismounting of bearings of different specifications, and as a result, applicable scope of the dismounting tool is expanded; a handle is arranged, so that more force can be saved during dismounting.

Description

technical field [0001] The invention belongs to the technical field of bearing processing equipment, and in particular relates to a dismounting tool for rolling bearings. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. When other parts move relative to each other on the shaft, it is used to reduce the friction coefficient during power transmission and keep the center of the shaft fixed. Among the oscillating shafts and rotating shafts that support mechanical systems, rolling bearings are the most used type of bearings. In the process of overhauling and scheduled maintenance of mechanical equipment, it is often necessary to disassemble the bearings. Because the inner ring of the bearing and the shaft are interference fit , its disassembly is relatively difficult. The existing disassembly method is carried out by beating and other tools.

Problems solved by technology

Among the oscillating shafts and rotating shafts that support mechanical systems, rolling bearings are the most used type of bearings. In the process of overhauling and scheduled maintenance of mechanical equipment, it is often necessary to disassemble the bearings. Because the inner ring of the bearing and the shaft are interference fit , its disassembly is relatively difficult. The existing disassembly method is carried out by beating and other tools. This disassembly method has the problems of long disassembly process, time-consuming and laborious, and low disassembly efficiency. At the same time, when disassembling, a little carelessness will cause Injury to auxiliary dismantling personnel or damage to other parts. In view of the problems existing in traditional disassembly methods, various existing tools for bearing disassembly emerge in endlessly. Each disassembly tool has its advantages and disadvantages, but the existing bearing disassembly Most of the tools have problems such as complex structure, troublesome production and assembly, and high cost

In addition, the existing disassembly tools still have a series of problems such as large friction force and easy to pull the shaft during the disassembly process.
