METHOD OF SECURING A BEARING RACE BY WELDING USING HEAT

摘要

The invention concerns a method of securing a bearing track which is journalled on a hollow shaft against rotational movement relative to the shaft. The bearing inner track is journalled against a step on the shaft and abutted by a retaining collar mounted on the shaft. An electron beam is applied to the bore of the shaft in a radial direction to penetrate firstly the shaft wall and then the retaining collar to weld them together so that a residual axial compressive load is produced sufficient to hold the bearing track against rotation relative to the shaft.
