Research on the motion characteristics of composite Curve-face gear transmission

Abstract

As a new type of gear transmission, composite curve-face gear transmission is used to transfer the power and composite motion of rotation and movement between the intersecting or interlaced axis. By using the theory of gear meshing, geometrical differential and space cam design, the motion principle and form of the composite curve-face gear transmission were discussed; the movement characteristics of the composite curve-face gear transmission were analyzed, including transmission ratio, rotation, movement and quick-return; the motion stability of the curve-face gear with different pitch curve forms was studied; and the forms of curve-face gear to realize stable and high-speed transmission were obtained. The correctness of the curve-face gear transmission is verified by experiment.
