Drive bearing assembly method and sleeve for assembling drive bearing

Abstract

The invention provides a driving bearing assembly method and a special sleeve for assembling a driving bearing. The driving bearing assembly method comprises the following steps: a bearing inner ring is heated to reach a preset temperature; the heated bearing inner ring is wiped; the bearing inner ring is sleeved in an axle; the special sleeve is placed on the outer end surface of the bearing inner ring; a rotary shaft holding box is stably rotated to the special sleeve; and the assembly is finished. The driving bearing assembly method can realize lossless assembly of the driving bearing, and prolongs the service life of the driving bearing.

Description

technical field The invention relates to assembly technology, in particular to a driving bearing assembly method and a sleeve used for assembling the driving bearing. Background technique Drive bearing, as an important part of the locomotive, its assembly method is very important. In the prior art, in the process of assembling the driving bearing, copper rods need to be used to knock the large end cover several times, wherein the large end cover is arranged on the inner end surface of the inner ring of the bearing. This knocking operation makes the residue on the copper rod easily fall into the inside of the drive bearing, thereby causing the drive bearing to be easily damaged and reducing the service life of the drive bearing. Contents of the invention The invention provides a driving bearing assembly method and a sleeve used for assembling the driving bearing, so as to realize the non-destructive assembly of the driving bearing and prolong the service life of the driv...
