Abstract
For the purpose of a detailed description of rotational vibration response of a helical gear pair having tooth surface deviation during light load transmission, we have already developed the numerical calculation method for gear vibration which can take any type of deviation into account. But there can be seen the tendency that the accuracy become worse when transmitting load is too low. Especially, gear pair's resonant frequency is too much influenced with transmitting torque comparing with the experimental results. To improve the accuracy of proposed simulation, we examine two types of tooth elastic deformation, tooth bending deformation and compressive deformation of tooth surfaces, precisely with vibration measurement and observation of contact pattern of meshing teeth.
