As a non-circular gear is equipped the motional characteristics of both cam and circular gear, it can be used for transmitting rotary motion at a variable rate in an instrument or a machine. This paper describes a CAD method for non-circular gears. It consists of: (1) Necessity and purposes of the research, (2) Mechanism of non-circular gears and the relationship between a shape and its transmission motion or velocity, (3) Design of teeth and pitch curves, such as an involute curve as a tooth curve, and an ellipse or a free-form curve of B-spline as a pitch curve defined by analytical geometry methods, (4) Calculation and adjustment of the number of teeth, (5) Distribution and trimming of teeth, (6) Creation of 3D models of the gears and (7) Discussions and conclusions.
