英文摘要：

We deduce the theoretical equation and working tooth profile equation of the central inner gear of a rolling movable tooth transmission using a cam with wave excitation, present the formulas for calculating the curvature of the tooth profile and analyze the characteristics of the curvature＇s distribution around it. The geometric shape, curvature distribution characteristics and NC machining of the tooth profile of the inner gear is simulated using the PRO/E software. The simulation results are useful for the analysis, design and manufacture of the inner gear.
