影响滚针离合器轴承摩擦角的几何因素

Influence of Geometry Factors on Frication Angle of Needle Roller Clutch Bearing

滚针离合器轴承是可单向传递轴和轴承座之间的扭矩 ,而反方向允许自由转动的一种复合功能轴承。本文在冲压成型外圈的锁紧斜面尺寸难以修改的前提下 ,分析了其配用的滚针或轴 (内圈 )的几何尺寸变化对摩擦角的影响。附图 4幅 ,参考文献

WT5BX] The needle roller clutch bearing is a kind of compound function bearing which transmits torque between the shaft and housing in one direction and allows free overrun in the opposite direction. The analysis of the friction angle effected by the dimension tolerances of the needles and shaft are given in this paper. It is found the engagement properties of the clutch can be adjusted a little by changing the dimension of the needles or shaft .
