TAPERED ROLLER BEARING FOR DIFFERENTIAL

摘要

PROBLEM TO BE SOLVED: To increase a load capacity without lowering the rigidity of a cage. SOLUTION: This tapered roller bearing 1 for a differential comprises an inner ring 2, an outer ring 3, a plurality of tapered rollers 4 rollingly disposed between the inner ring 2 and the outer ring 3, and the cage 5 holding the tapered rollers 4 at prescribed intervals in the circumferential direction. A roller factorγis increased more than 0.94, whereγis (roller quantity x averaged roller diameter)/(πx PCD). COPYRIGHT: (C)2006,JPO&NCIPI
