BEARING UNIT FOR A PINION SHAFT PROVIDED WITH THERMAL EXPANSION COMPENSATION

摘要

The invention relates to a bearing unit (2) for a gear shaft (3) which is cantileverly supported by two roller bearings (2a, 2b) and provided with a crown wheel (3. 1). Said gear shaft (3) is arranged in a gearbox case (1) with the aid of a bearing bush (2.1) which is mounted on one side in an axial direction in such a way that it is pivotable in a direction of the crown wheel (3. 1) when heat is raised. However, the gearbox case (1) dilates in an opposite axial direction oriented towards the crown wheel (3. 1). The two roller bearings (2a, 2b) are arranged on the side of the crown wheel (3. 1) with respect to the axial fixation of the bearing bush (2.1).
