Research on the Optimal Transmission Design of Planar Bar Mechanism

A creative method for the optimal transmission design of the planar bar mechanism is presented in this paper. By the method, crank-rocker mechanism, crank-slider mechanism and the corresponding six-bar mechanism with desired dimensions can be devised, in which basic parameters of the mechanisms such as time ratio, the oscillating angle of the rocker and the stroke remain unchanged and in the mean time, the minimum transmission angle obtains its maximum value. By the method, the combination form of the optimal transmission parameters can be obtained according to given design requirements so as to improve transmission property and realize the optimal transmission results. The design method is characterized by simple operation and convenient usage in practice.
