Rolling mill bearing demounting device

Abstract

The invention relates to a rolling mill bearing demounting device, and belongs to the technical field of rolling mill bearing maintenance equipment. The rolling mill bearing demounting device comprises a base, two sliding blocks in sliding connection with the two ends of the base, a connecting rod with one end fixed to the base, a rotating sleeve arranged on the connecting rod in a sleeving manner, a positioning plate fixed to the upper portion of the connecting rod, a bearing pressing plate and a hoisting ring; a handle is fixed to the upper portion of the rotating sleeve, two connecting rod mechanisms are symmetrically fixed to the two ends of any diameter of the lower portion of the rotating sleeve, and the other end of each connecting rod mechanism is hinged to the two sliding blocks; the bearing pressing plate is arranged on the positioning plate; through holes are formed in the bearing pressing plate and are arranged on the connecting rods in a sleeving manner, and the bottom face of the bearing pressing plate and the upper surface of the positioning plate are overlapped; and the hoisting ring is in threaded connection with the upper ends of the connecting rods. According to the rolling mill bearing demounting device, a rocker sliding block mechanism is used, rolling mill bearing demounting and mounting can be quickly and simply completed, and the demounting and mounting efficiency is improved; and meanwhile, the condition of scattering in the demounting and mounting process of multiple rows of bearings is avoided, and the bearing demounting and mounting safety is greatly improved.

Description

technical field [0001] The invention relates to a rolling mill bearing disassembly tool, which belongs to the technical field of rolling mill bearing maintenance equipment. Background technique [0002] Bearings of cold rolling mills in metallurgical enterprises need to be disassembled regularly for cleaning and maintenance. In the existing technology, manual disassembly and cleaning of rolling mill bearings are often used; because rolling mill bearings are multi-row bearings and have a large number of on-line bearings, the cleaning cycle requires a short period. Bearing disassembly and maintenance workload is large, disassembly and assembly is cumbersome, time-consuming and labor-intensive; and multi-row bearings are prone to scattering during disassembly and assembly, causing injuries to staff and posing a greater safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rolling mill bearing disassembly ...
