A device for removing bearings

Abstract

The invention discloses a bearing dismantling device. A transparent cover is installed on a shaft neck below a bearing. The bearing dismantling device comprises a pressing ring, a short lead screw, a first shaft sleeve, a long lead screw, a gland, a stud and a second shaft sleeve. The first shaft sleeve and the second shaft sleeve are respectively composed of two half shaft sleeves in a butt-connection mode, the inner diameter of the first shaft sleeve and the inner diameter of the second shaft sleeve are matched with the shaft neck of an end cover of a grinder, the outer diameter of the pressing ring is the same as the outer diameter of the transparent cover, the edge of the pressing ring and the edge of the transparent cover are respectively provided with at least six concentric holes, a base disk and a barrel body are welded to form the gland, the height of the barrel body is not smaller than the thickness of the bearing, the outer diameter of the base disk is slightly smaller than the outer diameter of the shaft neck of the end cover of the grinder, the base disk and the upper surface of the shaft neck of the end cover of the grinder are respectively provided with at least six concentric threaded holes, and the two ends of the short lead screw and the two ends of the long lead screw are respectively of a threaded structure. The first shaft sleeve and / or the second shaft sleeve are / is arranged between the transparent cover and the bearing, the combination portions are welded in a spot-welding mode, the pressing ring or the gland is arranged above the shaft neck of the end cover of the grinder, and the pressing ring or the gland is connected with the transparent cover through the short lead screw or the long lead screw and a lead screw nut. The bearing dismantling device is simple in structure, low in manufacturing cost, safe and reliable in dismantling process and free of damage to the bearing.

Description

technical field [0001] The invention relates to a device for removing a bearing, which belongs to the technical field of machinery. Background technique [0002] The bearings that are thermally installed on the journal of the end cover of the mill need to be disassembled for various reasons, but because the inner diameter of this kind of bearing is φ1000mm, and the assembly is thermally installed, it is very difficult to disassemble. There is no such special tool available in the prior art, so a dismounting tool for large bearings is urgently needed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tool that can remove the bearing that is heat-fitted on the shaft journal of the end cover of the mill. [0004] In order to solve this technical problem, the present invention provides a bearing dismantling device. The bearing is thermally installed on the journal of the end cover of the mill, and a transparent cove...
