Abstract: Aiming at the thermostability of dry gear hobbing machines, the heat flow characteristics and optimal control strategies were studied. By analyzing the features of drive method and structural layout, the complex and multi-source characteristics were explored for heat flow of dry gear hobbing machines. And further, multi-field coupled model was established for heat storage of dry gear hobbing machine based on macro and micro heat transfer mechanism. Finally, multi-dimensional control strategies were proposed for analyzing influence factor of thermostability. The involved strategies contain the collaborative optimization of thermostability, the field synergy enhancement of compressed air and the multi-sensor data fusion perceived control of the heat flow. 

Key words: dry gear hobbing machine, heat flow characteristic, thermostability, control strategy
