Kinematic analysis and simulation of noncircular gear-Carden circle planetary mechanism

The Carden circle planetary mechanism has simple structure, high reliability and easy realization of reciprocating linear motion. According to the geometric characteristics of the Carden circle planetary mechanism, the necessary conditions for the continuous motion of the structure are derived. The displacement, velocity and acceleration function of the sine wave produced by the Carden circle planetary mechanism were obtained by motion analysis. In order to meet the requirements of Carden circle planetary mechanism of the engineering application, the size of the components under certain conditions, through a combination of noncircular gear transmission characteristics, driving Carden circle planetary mechanism using uniform speed motor, it improved the output motion characteristics of the circle planetary mechanism, and increased its comprehensive performance. It can provide a reliable research method for the series combination mechanism and the structural optimization design.
