Modeling of Nutation Drive with Rolling Teeth
Applied Mechanics and Materials, 2009According to the pair transformation theory on mechanism derivation, the internal bevel gear meshing pair of nutation drive is replaced by rolling elements. In this manner, gear teeth are eliminated and the problem of manufacturing the interval bevel gear is solved completely.
