并不是所有的凸轮机构都对从动件的运动特性有极为严格的要求。在许多凸轮机构中,从动件要求的往往只是一个位移量,而对运动过程中速度特性的要求并不苛刻。在这种情况下,可以采用下面介绍的大半圆孔嵌装圆柱式凸轮代替盘状或平移式凸轮。这种新型凸轮的制造工艺较传统凸轮大为简化,不仅能大幅度降低制造成本,同时能相对提高凸轮的使用寿命。 Not all cam mechanisms have very strict requirements on the follower’s kinematics. In many cam mechanisms, followers often require only one displacement, while the speed characteristics of the movement are not critical. In this case, instead of a disk-shaped or translational cam, a cylindrical cam with a large semi-circular hole as described below can be used instead. This new type of cam manufacturing process greatly simplified than traditional cams, not only can significantly reduce manufacturing costs, while relatively improving the service life of the cam.
