摘要

直升机传动系统中的高重合度直齿圆柱齿轮多采用喷油方式进行润滑冷却，其温度特性关系到齿轮的使用寿命。基于计算流体力学（Computational Fluid Dynamics，CFD），建立了高重合度直齿圆柱齿轮喷油润滑温度场数值计算模型；采用气液两相流（Volume of Fluid，VOF）、多重参考系（Multiple Reference Frame，MRF）法获得了齿轮表面的温度和对流换热系数大小及分布；使用控制变量法分析了润滑油参数、工况参数、齿轮参数对齿面温度及对流换热的影响规律；在CL-100型齿轮试验机上开展了齿轮温度试验。结果表明，齿轮温度随载荷增加而升高的趋势与CFD仿真计算结果一致，高重合度齿轮温度高于普通重合度齿轮，而且随着载荷的增大，这种现象越明显。

Abstract

The spur gear with high contact degree used in the helicopter transmission system is lubricated and cooled by oil injection

and its temperature characteristics are related to the service life of the gear. Based on the computational fluid dynamics (CFD) idea

a numerical model for the temperature field of oil injection lubrication of spur gears with high contact degree is established. The volume of fluid (VOF) and the multiple reference frame (MRF) method are used to obtain the temperature and convective heat transfer coefficient of gear surfaces. The influence of lubricating oil parameters

working condition parameters and gear parameters on tooth surface temperature and convective heat transfer is analyzed by the control variable method. The gear temperature test is carried out on the CL-100 type gear testing machine. The results show that the trend of the gear temperature rising with the increase of load is consistent with the CFD simulation results. The temperature of the gear with high contact degree is higher than that of the gear with ordinary contact degree

and this phenomenon becomes more obvious with the increase of load.
