Thrust wheel assembling process

Abstract

The invention relates to the technical field of bearing processing, in particular to a thrust wheel assembling process. The assembling process comprises the following steps: S1, placing one bearing tobe assembled into a thrust wheel carrier on a fixed seat, downwards moving the whole thrust wheel carrier till the thrust wheel carrier is put on the bearing in a sleeving manner, and fixing the thrust wheel carrier with the bearing; S2, putting an isolation sleeve above the bearing, and maintaining the isolation sleeve to be coaxial with the bearing; S3, putting another bearing above the isolation sleeve, and maintaining the bearing to be coaxial with the isolation sleeve, and putting and fixing the bearing into the thrust wheel carrier. The thrust wheel assembling process overcomes the shortcomings in the prior art, optimizes the assembling flow, forms assembly line work, and greatly improves the assembling efficiency; meanwhile, the assembling process is improved; the problem of damageto the isolation sleeve and the problem of offset of an adjustment pad are optimized; workpiece damage is effectively avoided; the assembling production efficiency is improved; a detection procedureis added, so that the qualification rate of a workpiece is guaranteed; the production cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of support roller processing, in particular to a support roller assembly process. Background technique [0002] The supporting wheels are used to support the weight of the locomotive unit, and at the same time roll on the track (rail chain link) or the track surface of the track. In order to prevent derailment, the support rollers should also be able to prevent the crawler from causing lateral relative movement to it. When the locomotive group turns, the track rollers force the track to slip on the ground. [0003] Support rollers often work in mud, water, ash and sand, and are subject to strong impacts. The working conditions are extremely harsh and the rims are easy to wear. Therefore, the requirements for supporting rollers are: wear-resistant rims, reliable bearing seals, and low rolling resistance. [0004] The traditional way of assembling the support wheels is: [0005] 1. First press in a bearing from below...

AI Technical Summary

Problems solved by technology

[0012] Two problems are prone to occur during the assembly process. One is that there is a slight deviation between the shaft and the bearing. There is no effective positioning during the assembly process. The operator inserts the shaft by feeling. When the spacer between the two bearings is not in the center , when the shaft is pressed in from the bottom, it will damage the spacer, causing burrs on the spacer and ejection of the bearing, which will affect the subsequent assembly and component quality; second, the adjustment pad put in from the bottom is easy to be misaligned, and the rollers are pressed down When the adjustment pad is easily driven by the wall of the bearing hole of the roller, causing a part to slide between the oil seal and the wall of the bearing hole of the roller, and finally get stuck, causing the roller to fail to rotate
