Hydraulic disassembling structure of rolling bearing

Abstract

The invention discloses a hydraulic disassembling structure of a rolling bearing, and belongs to a mechanical disassembling structure. A conventional rolling bearing adopts an assembling structure which is disassembled through heating, so that during disassembling, the bearing is liable to deform after being cooled, and on-the-spot disassembling is not facilitated. According to the hydraulic disassembling structure disclosed by the invention, an oil outlet annular groove is formed in a bearing mounting section of a rotating shaft; a hydraulic oil channel is formed in the rotating shaft; a hydraulic interface is formed in one end of the hydraulic oil channel, and the other end of the hydraulic oil channel communicates with the oil outlet annular groove through an oil outlet hole; and when the rolling bearing is disassembled, the hydraulic interface is connected with a hydraulic device, so that high-pressure hydraulic oil flows to the oil outlet annular groove through the hydraulic oil channel and the oil outlet hole, the pressure is transmitted to an inner ring of the rolling bearing, the inner ring of the rolling bearing is stressed to be away from the bearing mounting section of the rotating shaft, and the rolling bearing can be disassembled. According to the hydraulic disassembling structure disclosed by the invention, the abuse existing in conventional methods for disassembling the rolling bearing by heating is overcome, and great improvement is generated by the hydraulic disassembling structure in aspects of safety, economical efficiency, operability and the like.

Description

technical field [0001] The invention belongs to a mechanical disassembly structure, in particular to a rolling bearing hydraulic disassembly structure. Background technique [0002] The existing rolling bearing disassembly, because the rolling bearing and the shaft adopt interference fit, most of them adopt the heating disassembly method: firstly, the inner ring of the rolling bearing is heated at a high temperature, so that the inner ring is heated and expanded, so that a gap is created between the inner ring of the bearing and the shaft, and then disassembled. This disassembly method needs to heat the inner ring of the bearing. Uneven heating can easily cause the bearing to deform after cooling, and the high temperature generated during the heating process is likely to cause safety hazards, which requires high personnel operation. Disassemble. In general, heating and disassembling rolling bearings not only affects the bearing life, but also has disadvantages in terms of s...
