中文摘要：

建立了面齿轮传动本体温度场的热平衡方程,研究了不同几何参数、工况下圆柱齿轮和面齿轮的本体温度场分布。研究结果表明：面齿轮传动达到本体温度场时,面齿轮的本体温度高于圆柱齿轮,且本体温度与转速、负载、环境温度和齿面粗糙度呈正相关关系,与齿轮的模数、压力角和齿数呈负相关关系。仿真结果也为面齿轮在乏油润滑状况下的寿命预测提供了初始的齿面节点温度数据。

英文摘要：

The heat balance equation for the bulk temperature field of face-gear meshing was built, and the bulk temperature field distributions of cylindrical gear and face gear were studied under different geometric parameters and working conditions. Results indicated that face-gear bulk temperature was higher than that of cylindrical gear when the face-gear system reaching to bulk temperature. Moreover, the face gear bulk temperature showed a positive correlation with the rotate speed, load, environment temperature and gear surface roughness, and it showed a negative correlation with gear modulus, pressure angle and tooth numbers. The result provides initial temperature data of tooth surface nodes for the facegear life prediction under the lack of lubrication conditions.
