摘要

This study develops a contact performance-driven method for skiving face gear drives using a single cutter, eliminating the traditional need for separate cutters to reduce production costs and time. First, the mathematical models of the tooth flanks for the face gear drives are established based on the gear skiving processes. Then, load tooth contact analysis (LTCA) model is established to calculate the contact performance data. Next, a two-stage optimization model is employed to determine the optimal parameters of the cutting edge with improved contact performances. The effectiveness of this method is validated through simulations and rolling tests. Compared with the traditional method, the proposed method can machine both the face gear and its mating pinion with a single cutter. Simulation results show that the proposed method avoids tooth surface edge contact, with the maximum tooth surface contact stress reduced by 31.7%, the contact ratio decreases by 21.5%, and the transmission error increases by 22.3%. Rolling tests verify the consistency of tooth surface contact patterns between simulations and experiments. The proposed method provides a reference for the cutting edge design of skiving cutters for face gear pairs.
