Analysis on the Motion Characteristics of the Crank-group Driving Mechanism by Graphical Method

Abstract

The new transmission mechanism crank-group driving mechanism is mainly used in some special light industrial machinery. Paper drew the mechanism's trajectory curve of the structure unit by a new way-the graphical method, analyzed it related to the trajectory function, and then studied the motion characteristics of the whole mechanism. The study shows that all the cranks' motion on the crank-group driving mechanism are synchronous and uniform at any time, the connecting rod truss composed of the parallel double crank mechanism is doing translation from beginning to the end. The conclusions are consistent with the previous research; it validated the correctness of the foregoing research, and then laid the theoretical foundation for the mechanisms widely used in future.
