发明名称 PINION SHAFT SUPPORTING BEARING DEVICE
摘要 PROBLEM TO BE SOLVED: To prolong the life of a bearing and improve the efficiency of a differential gear by reducing turning torque, in a pinion shaft supporting bearing device for supporting a pinion shaft 4 constituting an automotive differential gear in a rotatable relation in a differential case 1. SOLUTION: The bearing device supports the pinion shaft 4 in a rotatable relation to the differential case 1. A pinion gear side rolling bearing 6 comprises a cylindrical roller bearing 60 and an angular contact ball bearing 61 juxtaposed axially. A companion flange side rolling bearing 5 comprises an angular contact ball bearing 51 forming a double-row angular contact ball bearing together with the angular contact ball bearing 61 of the pinion gear side rolling bearing 6. The rolling bearings 5 and 6 are fixed to the pinion shaft 4 under a pre-load by coupling of a companion flange 7 in the pinion gear direction by means of a nut 15. COPYRIGHT: (C)2003,JPO
