Abstract
In this study two planetary gearset pinion needle bearing lubrication methods - forced flow into the bearings and splash lubrication were evaluated for their cooling effectiveness and their potential to improve bearing life. Bearing operating temperatures were measured by placing thermocouples in the support pins. Life tests were then run under “good” and “poor” lubrication conditions to determine the effect of lubrication on bearing life.
