Teeth Profile Design and Meshing Force Analysis of the Swing Output Cam Mechanism with Movable Teeth

In order to transform constant rotation motion into variable oscillation traverse output motion, a theoretical tooth profile, which could realize to output oscillation traverse motion in continuous or batch process, was designed, and then the working profile equations were derived for enclosed slot of actuating plate and the swing plate. On this basis, contact force models and algorithms of meshing pair were established in the light of force/torque balance equation and theory of Hertz, and taking the same load and equal swing angle as the example, the characteristics of meshing force of cam mechanism with movable teeth in the condition of different steel ball numbers and various motion laws were analyzed. The acquired result of meshing force analysis can be adopted as the theoretical basis for bearing capacity analysis, stiffness estimation, as well as structure design of the swing output cam mechanism with movable teeth.
