Better Needle Bearings for Universal Joints 660159
In applying needle roller bearings to universal joints, it is desirable to identify and quantify several factors, recognizing the interrelationship of these factors in order to obtain the ultimate in successful performance and increased life. This paper discusses various aspects to be considered in bearing design (proportions and clearances); manufacturing tolerances; use of different materials; and the importance of proper yoke and cross deflection, cross end play, cup grind relief and trunnion chamfer, crowned races, and controlled contour rollers.
