Firstly, the components of the mechanism are represented by polar coordinate vectors, then, t
2、he motion law of the slave roller of the cam is deduced from the motion law of the follower step by step according to the vector graph of the cam mechanism; lastly, the actual cam profile curve is figured out by the motion law of the slave roller. This method has the property of exactness, and can c
3、omplete the design of cam mechanism whose follower has complex motions. Key words: Cam mechanism; Polar coordinate vector ； Motion analysis ; Profile curve 0 Introduction In practice, many of the automated mechanical systems, often using the convex wheel and connecting rod body composed of a combina
4、tion of actions to achieve specific motion components requirements. In the combination mechanism, by design a specific cam profile curve to control the movement of the body machine, which are driven by the follower to get motion laws. During the design of cam profile curve, the first need is that according to the actual movement of follower requirements in order to know the follower motion Mathematical expressions; then, according to structural parameters, from the motion law of the follower t
