Air compressor main shaft bearing mounting method and auxiliary tool

Abstract

The invention discloses an air compressor main shaft bearing mounting method and an auxiliary tool. The auxiliary tool comprises a V-shaped main frame, main shaft bearings, spring locking clamps and asupport base plate; a compressor main shaft is mounted on the surface of a V-shaped port in the V-shaped bracket; a buffer rubber pad is arranged on the surface of the V-shaped port of the V-shaped bracket; the main shaft bearings are mounted at two ends of the compressor main shaft; the spring locking clamps are mounted on the outer sides of the main shaft bearings; end surface baffle plates aremounted on two sides of a V-shaped groove; the V-shaped groove is mounted on the surface of the support base plate through a movable positioning stopper; and the support base plate is mounted in an electric heating water boiling furnace. The air compressor main shaft bearing mounting method and the auxiliary tool have the advantage of low cost, and can be assembled in general air compressor use departments with implementation conditions to reduce the reciprocating transportation cost and the assembly cost of sending the compressor main shaft and the bearings to professional manufacturers or original manufacturers.

Description

technical field [0001] The invention relates to the technical field of air compressor main shaft repair, in particular to an air compressor main shaft bearing installation method and auxiliary tooling. Background technique [0002] A small amount of interference fit is generally used between the bearing and the shaft to ensure the accuracy of the rotating machine and reduce noise. During the long-term use of the air compressor, when the matching position between the compressor shaft and the bearing is worn and repaired again, the bearing needs to be reassembled. [0003] At present, when installing the air compressor main shaft bearings on the market, due to the large size of the air compressor main shaft, the main shaft rotary support bearing is heavy, the bearing assembly is difficult, and the matching precision between the bearing and the main shaft is high, relying on the commonly used methods such as knocking and heating. , not only the assembly time is long and the ef...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for installing the main shaft bearing of an air compressor and an auxiliary tooling to solve the problem that the main shaft bearing of an air compressor on the market is installed due to the large size of the main shaft of the air compressor, and the rotating support bearing of the main shaft is relatively heavy. , the bearing assembly is difficult, and the matching precision between the bearing and the main shaft is high. Relying on the commonly used methods of beating and heating for assembly, not only the assembly time is long and the efficiency is low, but also the heating is uneven, and the circumferential expansion of the bearing is inconsistent, which is easy to cause the bearing and fit. The surface and other parts are damaged, which affects the service life of the equipment
