摘要

高速齿轮箱内的复杂流场通过影响齿轮喷油润滑特性，进而影响传动系统的传动效率和工作性能。针对高速齿轮箱复杂流场及挡板结构带来的影响等问题，开展了高速齿轮喷油两相流场及润滑特性研究。基于计算流体力学方法，建立高速斜齿轮喷油润滑两相流场分析模型，分析了两相流场分布特性；在此基础上，研究了喷油参数（如喷油速度、喷油夹角、轴向角度）以及齿轮挡板对喷油润滑特性的影响规律。结果表明，高速斜齿轮喷油润滑时，表面油液有偏斜现象；通过提高喷油速度或增加正轴向角度，可以改善油液偏斜现象，提高润滑效果；齿轮挡板对油液起着导流作用，其中，设置轴向挡板有利于增加齿面的油液。为高速齿轮箱两相流场分布特性研究及喷油润滑优化设计提供了依据。

Abstract

The complex flow field in the high-speed gearbox affects the transmission efficiency and performance of the transmission system by affecting the gear oil injection lubrication characteristics. Therefore

it is necessary to carry out research on the two-phase flow field and lubrication characteristics of high-speed gear oil injection considering the complex flow field of high-speed gear box and the baffle structure. Based on the computational fluid dynamics method

a two-phase flow field analysis model of high-speed helical gear oil injection lubrication is established

and the two-phase flow field distribution characteristics are analyzed. On this basis

the effects of injection parameters such as injection speed

injection angle

axial injection angle

and gear baffle on the injection lubrication characteristics are further studied. The results show that the oil on the surface of high-speed helical gear inclines to one side. By increasing the injection speed or adding the positive axial angle

the oil deflection and the lubrication effect can be improved. The gear baffle plays a role in guiding the oil

and the setting of axial baffle is conducive to increasing the oil on the tooth surface. This study provides a basis for the study of two-phase flow field distribution characteristics of high-speed gearboxes and the optimization design of oil injection lubrication.
