Research on Stress of Shifting Pair of End Face Harmonic Gear Drive of Oscillating TeethZHANG You-lin, FENG Si-ping, WANG Wu, XUE Shu-cheng (School of Mechanical & Electronic Engineering,Wuhan University of Technology,Wuhan 430070,China)The end face harmonic gear drive of oscillating teeth was a new type of the spatial oscillating teeth transmission. Its bearing capacity had a substantial increase on the basis of preserving all merits of the common harmonic gear drive. In this paper, the stress of the shifting pair between the oscillating teeth and sheave guide groove was analyzed. Based on the single-tooth drive, the structural condition of the single-sided contact force analysis of the shifting pair between the oscillating teeth and guide groove was deduced. It provided a theoretical basis for the structural design of the shifting pair of the end harmonic gear drive of oscillating teeth.oscillating tooth; end face harmonic; shifting pair; stress
