中文摘要：

根据传热学理论和面齿轮的啮合特性,利用APDL语言进行移动热源的加载,对面齿轮进行瞬态热分析,得到了不同工况下面齿轮齿面不同区域的节点温度数据。研究结果表明：面齿轮传动过程中,提高面齿轮齿面精度、使用动力粘度相对较大的润滑油以及降低齿轮的转速和接触载荷,有助于延长面齿轮的使用寿命。此结论为面齿轮寿命的预测提供了齿面啮合的温度数据。

英文摘要：

According to heat-conduction theory and face-gear meshing characteristics, transient thermal analysis is conducted with APDL language for moving heat source loading, the node temperature data in different regions of face-gear tooth surface is obtained under different working conditions. Results indicate that during face gear transmisson, improving face-gear tooth surface precision, using lubricating oil with relative high dynamic viscosity and lowering face-gear rotate speed and contact load could help to prolong face-gear service life. The conclusions provide temperature data of tooth surface meshing for face-gear life prediction.
