凸轮是提供最可靠的周期性重复运动的机构,普遍应用于内燃机、自动车床、办公机械、传送器和其他制造工艺设备中。凸轮的外形多种多样。凸轮机构一般由二个元件组成:凸轮(一种旋转倾斜平面)及具从动件。凸轮的运动形式有匀速旋转,(?)旋转,摆动和直线往复运动等,下列各图表示了各种凸轮机构在各种机械中的应用。 Cams are the most reliable mechanism for periodic repetitive movements and are commonly used in internal combustion engines, automatic lathes, office machines, conveyors and other manufacturing process equipment. The shape of the cam is varied. Cam mechanism generally consists of two components: cam (a rotating inclined plane) and follower. The form of cam movement with constant rotation, (?) Rotation, swinging and linear reciprocating motion, the following figures show a variety of cam mechanism in a variety of mechanical applications.
