Abstract

The invention discloses a component and bearing disassembly tool, which comprises a bottom plate, a support plate, a bushing and a part adjustment pad; There is a conical profile, and the conical profile is offset against the conical profile inside the part adjustment pad; the bushing is set on the boss, the bushing is cylindrical, and a threaded hole is opened in the center of the top end of the bushing. Drive bolts are set in the threaded holes; a support plate is set on the outer side of the bush, and a connection part is provided between the bush and the support plate, and the two are connected by bolts; the support plate is provided with several guide holes along the circumferential direction, and the guide A hook-shaped bolt is arranged in the hole, and the hook-shaped bent section of the hook-shaped bolt is against the inner end surface of the bearing. A fastening bolt is also arranged on the hook-shaped bolt. The driven end of the driving bolt presses the bottom plate inwardly, and the hook-shaped bolt pushes The bearing is pulled outwards, and the axial force of the bolt transmission is large, and the operation of splitting the bearing by the present invention is convenient, quick and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of bearing assembly, and in particular relates to an assembly and a bearing disassembly tool. Background technique [0002] In the process of engine assembly, debugging and overhaul, the bearing installed in the inner hole of the journal of the high-pressure rotor needs to be assembled and disassembled many times. There is an interference fit between the outer ring of the bearing and the inner hole of the journal, and the long fitting section must be pulled out completely. Shaft ends cannot be blocked. One side of the upper and lower ends of the bearing is closely connected with the adjustment piece, and the other side is axially locked with a nut, and there is a reserved through groove on the adjustment piece. Usually, the leakage of the bearing end face is directly disassembled by using a universal puller, hooking the bearing end face with a claw, supporting the support plate on the shaft end face, and di...
