Design and Research on Two-Degree of Freedom Spherical Gear
This paper deals with the analysis and studies in the tooth profile of robot flexible joint spherical gear. A new type of two-degree of freedom conical concave spherical gear is proposed, calculated by analysis of teeth with tapered concave conjugate of the convex teeth shape. The undercut, overlap coefficient are analyzed and calculated to ensure the rational structure of the spherical gear. The conical concave tooth is using in the spherical gear, which makes the process of manufacturing easier and can improve the manufacturing precision and reduce the costs.
