摘　　要：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.
