Dismounting method of lower half bearing bush of coupling

Abstract

The invention belongs to the technical field of bearing bush maintenance, and in particular, relates to a dismounting method of a lower half bearing bush of a coupling. The dismounting method comprises the following steps: after an upper half bearing bush is dismounted, an auxiliary device is fixed on equipment body on the outer side of the lower half bearing bush; the auxiliary device comprises asupport rod fixed on the equipment body; the upper part of the support rod is rotationally connected with a rotating shaft; one end of the rotating shaft is an operation rod, and the other end is provided with a rotating disc; the rotating disc is higher than the lower half bearing bush; a rope body is wound on the rotating disc; a free end of the rope body is connected to one side of the lower half bearing bush; and the operation end drives the rotating disc to rotate through the rotating shaft, so that the rope body is tightened to lift up the lower half bearing bush. The dismounting methodof the lower half bearing bush of the coupling improves the construction efficiency and reduces the operation risk through a mode of knocking on one side and traction on the other side of the bearingbush.

Description

technical field [0001] The invention belongs to the technical field of bearing bush maintenance, and in particular relates to a method for removing a bearing bush in the lower half of a coupling. Background technique [0002] The bearing pad is the contact part of the sliding bearing and the journal, and its shape is a half-cylindrical surface in the shape of a pad. Its main function is to support, reduce friction and improve the rotation accuracy. It is widely used in large-scale modern metallurgical industries, such as dust removal fans, combustion-supporting fans and blast furnace gas residual pressure power generation devices of blast furnace systems, all of which are inseparable from bearing bushes. During the inspection and replacement of bearing pads, the bearing pads need to be removed, because the bearing pads are divided into upper and lower halves. Generally, the upper pads can be removed directly, but the lower half of the bearing pads cannot be removed directly ...

AI Technical Summary

Problems solved by technology

During the inspection and replacement of bearing pads, the bearing pads need to be removed, because the bearing pads are divided into upper and lower halves. Generally, the upper pads can be removed directly, but the lower half of the bearing pads cannot be removed directly because they fit in the tile groove; copper is required. Hitting one side of the bearing bush with a stick to disengage the bearing bush from the main body of the equipment, and taking it out manually will easily cause damage or damage to the bearing bush.
