凸轮机构从动件滚子半径的设计

Design of Roller Radius of Cam Slave Mechanism

凸轮机构从动件滚子半径的大小直接影响凸轮副接触处的接触应力和润滑油膜厚度并影响凸轮机构的寿命和运动精度。从接触应力和润滑油膜厚度两方面入手 。

Roller radius sizes of slave mechanism of cam machine affect the touch-stress of touch region and the thickness of lube film directly. The optimize design of roller radius is discussed based on the touch intensity and the thickness of lube film in this paper.
