Disassembling and assembling device for parallel dual-supporting roller shaft bearings

Abstract

The invention relates to a disassembling and assembling device for parallel dual-supporting roller shaft bearings. The disassembling and assembling device comprises a base, two bearing seat disassembling and assembling handcars, and a dual-supporting roller lifting handcar, wherein the bearing seat disassembling and assembling handcars are positioned on the left side and the right side of the base; the dual-supporting roller lifting handcar is positioned at the middle positions of the base; the two bearing seat disassembling and assembling handcars are respectively a left bearing seat disassembling and assembling handcar and a right bearing seat disassembling and assembling handcar which are symmetrically arranged; the dual-supporting roller lifting handcar is positioned between the two bearing seat disassembling and assembling handcars; each of the bearing seat disassembling and assembling handcars comprises a support platform, wherein a second sliding rail is laterally arranged on the support platform. According to the disassembling and assembling device disclosed by the invention, the defects of being high in labor intensity and low in working efficiency, and easily damaging a support roller and bearing seats in the process that parallel dual-supporting rollers are artificially disassembled and assembled are overcome, the labor intensity is effectively reduced, and the disassembling efficacy and the assembling efficacy are greatly improved.

Description

technical field [0001] The invention relates to a dismounting device for a bearing seat. Background technique [0002] In the metal rolling process, defects such as wear, scratches and fatigue layers will appear on the back-up rolls after a certain period of time. Time just needs to take the back-up roll out of the rolling mill for grinding. [0003] Before grinding, the bearing housings at both ends of the back-up roll need to be disassembled; after grinding, the bearing housings must be reinstalled for re-rolling. It is very difficult to assemble the side-by-side double support rolls. The two support rolls are arranged horizontally and share a set of bearing housings. At the same time, the centerlines of the two corresponding bearings in the same bearing seat must be kept coincident for assembly; due to the large diameter and heavy weight of the back-up rollers, it is difficult to adjust the level and distance between the centerlines of the two back-up rollers during man...

AI Technical Summary

Problems solved by technology

It is very difficult to assemble the side-by-side double support rolls. The two support rolls are arranged horizontally and share a set of bearing housings. At the same time, the centerlines of the two corresponding bearings in the same bearing seat must be kept coincident for assembly; due to the large diameter and heavy weight of the back-up rollers, it is difficult to adjust the level and distance between the centerlines of the two back-up rollers during manual installation so that they are in line with the bearings Corresponding to the bearing seat, it greatly increases the difficulty of assembly. A slight negligence will damage the roller surface of the backup roller and damage the accessories on the bearing seat, and even cause a safety accident.
