摘　　要：两种推杆运动规律的确定凸轮基圆半径诺模图汪萍侯慕英田野（内蒙古工业大学机械系０１００６２）１引言确定凸轮的基圆半径是凸轮机构设计中的一个重要问题。凸轮基圆的大小除了必须考虑凸轮轴尺寸的结构因素外，在一般情况下都是按机构压力角不超过许用值为原则来进行...This paper studied the calculation formula of base circle radius of cam according to allowable pressure angle for plate cam mechanism with push rod in rectilinear motion trained on the centre while the follower is moving according to a moving law of equal acceleration or deceleration and modified uniform velocity.From this and in accordance with the principle of nomography the nomographs employed comveniently in engineering are eslablished.These nomographs are the modification and supplement of the original nomographs.
