为探讨喷油方式对齿面温度的影响，以斜齿轮为研究对象，通过CFD仿真和试验研究不同喷油方式对斜齿轮齿面温度的影响。针对斜齿轮喷油润滑过程的特点，分析其齿面摩擦生热量，简化轮齿喷油润滑计算模型，并基于CFX进行齿面对流换热仿真研究，得到了不同喷油方式下的齿面温度；基于功率开放式斜齿轮试验平台，对不同喷油方式下的齿面温度进行了试验测量，与仿真计算结果进行对比分析。结果表明：在高速重载斜齿轮传动系统中，啮出侧喷油润滑的方式比啮入侧喷油润滑方式的冷却降温效果要好。

Reasonable design and selection of gear transmission oiljet method,oiljet angle and other oiljet lubrication parameters are of great significance for controlling the meshing tooth surface temperature,improving the tooth surface antiscuffing capacity and extending the service life.In order to investigate the influence of oiljet method on tooth surface temperature,this paper uses helical gears as the research object,and the influence of different oiljet lubrication methods on the tooth surface temperature of the helical gear is studied by CFD simulation and experiment in this article.According to the characteristics of the helical gear oiljet lubrication process,the frictional heat generation of the tooth surface is analyzed,the calculation model of the oiljet lubrication of the gear tooth is simplified,the tooth surface heat transfer simulation is carried out based on CFX,and the tooth surface temperature under different oiljet modes is obtained.Based on the power open helical gear test platform,the tooth surface temperature under different oiljet modes is tested and compared with the simulation results.The results show that for the highspeed and heavyduty helical gear transmission system,the oiljet lubrication on the gear engaging side has better cooling effect than on the gear disengaging side.
