Abstract

The inevitable elastic deformation and vibration displacement of components can cause gear mesh misalignment (MM) in gear systems, thereby affecting the actual contact state of gear pairs and system dynamic performance. A novel three-dimensional (3D) dynamic gear contact model is proposed in this study for determining the 3D dynamic contact state of gear pairs considering system flexibility. By combining the loaded tooth contact analysis (LTCA) model with the MM calculation approach proposed in our published work, a proxy model for dynamic mesh excitations of gear pairs with system flexibility is developed for improving the solution efficiency. An efficient solution method of the proposed dynamic gear contact model is established through coupling the proxy model of dynamic mesh excitations and Newmark numerical integration method. It is conducted in-depth research on the influences of input speed, shaft parameters and gear installation position on dynamic MM and dynamic contact stress (CS), dynamic composite mesh stiffness (CMS) and dynamic composite mesh error (CME), as well as dynamic mesh force (DMF) and dynamic transmission error (DTE) of gear pairs.
