摘要：This paper presents 3D modeling and simulation for a new type of globoidal indexing cam mechanism with steel ball. The characteristic of this mechanism is that cam raceway section is double circular arc section, and this characteristic is helpful to realize approximate rolling transmission. Profile surface equation of globoidal cam is established according to rotary transform tensor theory and meshing theory. Coordinate points of profile surface is obtained by MATLAB software. 3D model of parts of globoidal indexing cam mechanism with steel ball is built by Pro/E software. In Pro/E software these parts are assembled, and kinematics simulation is performed. Through kinematics simulation angular displacement, angular velocity and angular acceleration of indexing plate are obtained. Finally dynamic simulation of this mechanism is performed by ADMAS software, and contact force between cam and roller is obtained.
