SPHERICAL GEAR WITH CONCAVE CONE TEETH AND ITS APPLICATION IN ROBOT JOINT

The driving principle and the manufacturing method for spherical gear with concave cone surface teeth are put forward. The profile of covex teeth of this kind of gear is analyzed and calculated. The theoretical feasibility of this kind of gear is proven by the analysis of profile, contact ratio and undercut. It makes the process of manufacturing easier and can improve the manufacturing precision and simplify the manufacturing process.
