英文摘要：

Hyperboloidal-type normal circular-arc gear is a novel transmission technology in which the circular-are tooth profile is developed into the cross-axis gear transmission. Based on the transmission principle of hyperboloidal- type normal circular-arc gears, the design method of tooth profile with point contact was presented, and the mathematical model of tooth surface was deduced; in the situation that the friction and the friction moment were considered, the velocity and the forced action were analyzed, and then the formula of meshing efficiency of hyperboloidal-type normal circular-arc gears was deduced, the effects of design parameters on the efficiency were investigated. The results provide theoretical reference for the optimal design of hyperboloidal-type normal circular-arc gears.
