圆柱凸轮机构属于空间凸轮机构,而凸轮机构从动杆的运动形式又可分为两种:从动杆运动方向平行于凸轮轴线,另一种是从动摆杆以K作支点往复摆动。我们主要分析后者的运动误差和干涉问题。从图1可知,从动摆杆以K作支点,摆动到高点c时与凸轮轴线的偏离量为L。由图2看出,由于偏离量L而产生凸轮槽与凸轮径
Cylindrical cam mechanism belongs to the space cam mechanism, while the cam follower rod movement form can be divided into two types: the direction of movement of the follower rod parallel to the cam axis, and the other is from the swing lever to K as the fulcrum reciprocating swing. We mainly analyze the latter’s motion error and interference problems. As can be seen from FIG. 1, the deviation from the cam axis is L when the oscillating rod is driven by K as the fulcrum and swings to the high point c. It can be seen from FIG. 2 that the cam groove and the cam diameter are generated due to the deviation amount L. FIG
