摘要：
Theoretical calculation equation of meshing efficiency of globoidal indexing cam mechanism with steel ball is derived by analyzing the motion of steel ball and power loss of the mechanism. Based on the features of loads, meshing efficiency and influencing factors are analyzed. Calculation and analysis show that meshing efficiency varies with cam angle, friction coefficient and sliding velocity are major influencing factors, with the increase of them, meshing efficiency increase. Pretightening force, contact ratio factor and cam motion rule are minor influencing factors, meshing efficiency increases with the increase of pretightening force, the contact ratio factor affects meshing efficiency and the distribution of losing power, cam motion rule affects meshing efficiency by mean of it's influence on inertia load of the mechanism, this research has guiding significance for design and manufacture of the mechanism.
