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. | | 查看全文查看/发表评论下载PDF阅读器 | |
