Tooth Profile Analysis and Simulation of the Tow-tooth Defference Swing-rod Movable Teeth Transmission

According to the transmission structure and principle of two-tooth difference swing-rod movable teeth transmission, the theoretical and actual profile equation of central wheel was derived according to the engagement theory of two-tooth difference swing-rod movable teeth transmission and the tooth profile is simulated using MATLAB software.The effects of parameters,such as the transmission ratio,radius of movable tooth, length of swing-rod and the cam profile,on the tooth profile of the centeral wheel is analyzed. Formulas for calculating curvature and curvature radius of the central wheel are deduced and its variation curve was plotted respectively. The solid model of centeral wheel is established in Pro/E software and the curvature distribution characteristics is simulated using the Pro/E software.The research result can be used as the references for geometrical design of this type of geometric design and accuracy analysis.
