Basic Parameters Of The Cam

Cam mechanism is generally a high auxiliary mechanism composed of three components: cam, follower and frame. The cam is usually rotated continuously at constant speed, and the follower is designed according to the requirements of use to obtain a certain regular movement. Cam mechanisms can achieve complex motion requirements and are widely used in various automated and semi-automated mechanical devices, through which almost any action can be generated.

A cam can be defined as a machine with a curved surface or groove, by which the oscillation or rotation of another component, the follower, can provide a preset motion. The path of the mover is mostly confined to a chute to obtain reciprocating motion. In the recovery of the stroke, sometimes rely on its own weight, but some mechanisms often use the spring as the recovery force in order to obtain the exact action, and some use the guide groove to make it move on a specific path
