| Research Abstract |
For these years, marine transmissions having high capacity have become an urgent need. In order to design hyper conical gears under stricter design requirements, the tooth surface fatigue strength must be identified experimentally. First, we developed relative tooth surface analysis of a pair of hyper conical gears. Secondly, we designed and constructed the testing machine for tooth surface strength of hyper conical gears. The fatigue test was carried out on a different load condition. Finally, we examined the contact stress calculating formula of hyper conical gears.
