Analysis of composite motion law and force of high speed curve-face gear

Abstract

A new type of curve-face gear pair - high speed curve-face gear pair is proposed. It combines the high speed cam motion law and the curve-face gear transmission, and can transmit rotation/axial motion and power between intersecting axis. The meshing coordinate system of the gear transmission is established and the basic principle of engagement is expounded. The composite motion law and force of high speed curve-face gear drive are analyzed, and influences of the basic structural parameters on the pressure angle and the force are analyzed in detail. The comparison between the experimental results and the theoretical results shows that the basic principle and design of the gear transmission are verified.
