Thermal elastic coupling analysis and dynamic performance optimization of high precision involute gear
For high-speed gears,the deformation of the meshing tooth surface after heating was studied.High-precision parameterized model was adopted and the tooth surface parameters based on thermal elastic coupling theory were reconstructed and finite element contact simulation was conducted.Based on the simulation results,the optimization objective was to minimize the transmission error amplitude of the gear set,for which a topology modification scheme was selected while considering the influence of tooth surface thermal deformation on the design of gear tooth modification quantity.Based on the modification plan,finite element simulation and experimental grinding were conducted simultaneously to compare and evaluate the dynamic performance of the gear pair from three aspects:gear transmission error,tooth surface contact spots,and gear vibration.The finite element simulation and topological modification was demonstrated that it could improve the dynamic performance of the gear set significantly.
