A new cam-geared mechanism for exact path generation

Abstract

A new cam-geared mechanism, consisting of a cam-follower and elementary planetary gear train is proposed for exact path generation. The formation and mobility of the proposed mechanism are illustrated in detail, in addition to inverse kinematic analysis of the design and the design procedure. The advantages of the new design include its simple, compact structure, simple design procedure and no numbers limitation of precision point. This new mechanism is suitable for generating diverse continuous curve paths and symmetric curve paths with an intersection. Examples are provided to show the feasibility and effectiveness of this proposed method.
