A Diagram Design Method for the Optimal Transmission Angle of the crank rocker Mechanism

A novel method of realizing the optimal transmission of the crack and rocker mechanisms is presented in this paper.The optimal combination design is made by finding the related optimal transmission parameters.The diagram of the optimal transmission is drawn.In the diagram,the relation among minimum transmission angle,the coefficient of travel speed variation,the oscillating angle of the rocker and the length of the bars is shown,concisely,conveniently and directly. The method is of the main following characteristics,It is to achieve the optimal transmission parameters under the transmission angle by directly choosing in the diagram,according to the given requirements.The characteristics of the mechanical transmission can be improved to gain the optimal transmission effect by the method.Especially,the method is simple and convenient in the practical use.
