第十章凸轮机构

10.1 凸轮机构的应用与分类

10.2 从动件的常用运动规律

10.3 移动从动件盘形凸轮轮廓曲线的图解设计

10.1 凸轮机构的应用与分类

10.1.1 凸轮机构的应用


内燃机	配气机构

自动车床上的走刀机构	分度转位机构

10.1.2 凸轮机构的分类

按照凸轮的形状不同可把凸轮分为以下几种:

（1）盘形凸轮


尖顶移动从动杆盘形凸轮机构	尖顶摆动从动杆盘形凸轮机构


滚子移动从动杆盘形凸轮机构	滚子摆动从动杆盘形凸轮机构


平底移动从动杆盘形凸轮机构	平底摆动从动杆盘形凸轮机构

（2）移动凸轮

（3）圆柱凸轮

圆柱凸轮

（4）曲面凸轮

按锁合方式的不同凸轮可分为：力锁合凸轮，如靠重力、弹簧力锁合的凸轮等；形锁合凸轮，如沟槽凸轮、等径及等宽凸轮、共轭凸轮等。

沟槽凸轮


等宽凸轮	等径凸轮
