The Mechanics Model and the Analysis of Strength on the Active Tooth Transmission with a Few Difference of Tooths

In this paper, the forcing model of the active tooth transmission with a few difference of tooths is found for the conjugate curve of a tooth pattern of the internal gear wheel being formed by the active tooths, the shock wave instrument and the guiding slots of the active tooth frame which arc the roller, eccentric wheel and plan, respectively. According to the principle of resistance power and driving power being equal in amounts, the key parameter, the greatest acting force acted on the active tooths by the revolving arm ball bearing of the shock wave instrument is resulted. The mathematic formula of the force distribution of each clinching mates is obtained. According to the experimental result of photoclasticity in paper (3),thc model on strength analysis is found for the active tooth transmission with a few difference of tooths. The formula of strength calculation is obtained for the mainly transmissive compment parts: the fixed internal gear wheel, the active tooth frame and the revolving arm ball bearing. A simple and convenient calculation method is suggested for the practical design.
