Experimental study on thermal dynamic characteristics of gear transmission system

Abstract In order to study the influences of heat on dynamic characteristics of gear transmission system, the thermodynamics equation of torsional vibration of gear transmission system was derived based on the meshing thermal stiffness of gears. Meanwhile, an experimental platform for vibration testing of the system was established. The dynamic responses of the system under different working conditions were tested. The effects of load, rotational speed and heat on the dynamic characteristics of the system were studied by comparing and analyzing the experimental data, and the influence mechanism of the heat on the dynamic response was also studied. The results show that the load and rotational speed are the main factors that affect the dynamic characteristics of the system; the larger the system load, the larger the amplitude of vibration response, and similarly, the higher the rotational speed, the larger the amplitude of vibration response. The heat (temperature) affects the dynamic characteristics of the system by changing the involute characteristic and the meshing stiffness of the gear. When the initial temperature of the gear is lower than the calibration temperature, with the increases of the temperature, the vibration amplitude of the system decreases first and then increases. However, the natural frequency increases first and then decreases. Both of them showing a nonlinear variation. The experimental results effectively verify the correctness of the theoretical model.
