摘要

Advantages of asymmetric gear include larger load carrying capacity, smaller vibration and longer life. Vibration of the gear system due to the change of the direction of the friction force can be avoided when gears drive meshing beyond the pitch point. In this paper, the basic theory of the asymmetric gear with double pressure angles driving system meshing beyond the pitch point is developed. And the influence of gear pressures on the contact stress of driving gear of asymmetric increasing-speed spur gear drive system meshing in front of the pitch point is analyzed. Results show that the contact stress of asymmetric increasing-speed gear meshing in front of the pitch point can be effectively reduced by tuning the pressures on the driving side.
