Abstract: According to the gear meshing theorem, the ordinal design of the pitch curve and tooth surface of the gear pair is presented to realize the predicted transmission function for different application. Based on the complex motion and applications of curve face gear, the transmission ratio and axial movement speed are proposed by space coordinate transformation, also the slip velocity equation on the tooth surface curve face gear is established. The sliding characteristics on the tooth surface with different parameters are given. The results show that the size and direction of sliding velocity vary with the tooth height, and the sliding characteristics of the 5 teeth are different during the half cycle.

Key words: curve face gear pair, compound motion, surface sliding, function reproduction, tooth surface equation
