Analysis of Load Sharing Characteristics of Planetary Gear Trains Considering Temperature Effects
Gu Yunpeng
Abstract：In order to analyze the change of load sharing characteristics of the planetary gear transmission system under the influence of temperature change,a pure torsional multi-degree of freedom dynamic model of the spur gear planetary gear train was established in this study.In the model,the effects of backlash,gear train comprehensive error and time-varying mesh stiffness were considered,and the dynamic equation of the plane-tary gear train was derived.The variation of gear parameters under the influence of temperature effect was ana-lyzed,and the dynamic load sharing coefficient was taken as the evaluation index to study the variation of load sharing characteristics of the transmission system under the temperature effect.The analysis results show that the increase of the working environment temperature of the planetary transmission system will worsen the unbal-ance load,which will be adverse to the stable operation of the transmission system.
