This article presents a sphere-face gear pair by substituting the convex spherical gear for the pinion of a conventional face gear pair. The sphere-face gear pair not only maintains the advantages of the face gear pair with a longitudinally modified pinion but also allows variable shaft angles or large axial misalignments. Meshing characteristics of the proposed gear pair are studied in this article. The mathematical models of the sphere-face gear pair are derived based on machining principles. The tooth contact analysis (TCA) and curvature interference check are conducted for the sphere-face gear pair with variable shaft angles. The loaded TCA is also implemented utilizing the finite element method. The results of numerical examples show that proposed gear pair has the following features. Geometrical transmission error of constant shaft angle or varying shaft angle is zero; contact points of the sphere-face gear set with variable shaft angle are located near the centre region of face gear tooth surface; there is no curvature interference in meshing; and transmission continuity of the gear pair can be guaranteed in meshing.

A composite motion eccentric helical curve-face gear pair consisting of a helical non-circular gear and an eccentric helical curve-face gear is put forward based on the combination of eccentric gear and curve-face gear. This new gear pair can implement the rotation of intersected axes as well as the movement of output axe. Based on the spatial coordinate transformation theory, the coordinate system of eccentric helical curve-face gear pair is obtained and the pitch curve of eccentric helical curve-face gear is designed. The meshing equation and the tooth surface equation of eccentric helical curve-face gear are derived based on the spatial gear engagement theory and the conjugate surface theory. By changing the different parameters of eccentric helical curve-face gear pair, the influencing factors and variation of transmission ratio, pressure angle and kinematics are analyzed. According to the motion relationship of the gears and the method of generation, the establishment of solid model for the eccentric helical curve-face gear is presented with the application of SolidWorks. Furthermore, the correctness of the design theory of eccentric helical curve-face gear pair is verified by using the motion simulation and the experimental verification.

Rough machining is a major stage of production in face-gear precision manufacturing, and flexible, universal, and efficient rough machining is conducive to the reduction of manufacturing cost and time. Therefore, in this paper, the planing method for spur face-gear processing with a 4-axis CNC planer is proposed, together with a detailed study on the principle of meshing between the shaper and the face-gear, equations of the shaper tooth surface and the face-gear tooth surface, and the application of the planer tool to copy the shaper. Then, on this basis, equations of profiling curves as well as equations of the swing angle range and the radical feed range of the planer tool are derived. Finally, the method of planing the spur facegear through multi-group envelopes is proposed with the NC processing code written according to the above principle, and the feasibility of the planing method for the spur face-gear and the correctness of the NC code are proved by the results of the simulation processing test based on the Vericut software.
