摘要

为了解决乏油工况下的齿轮润滑问题，探究使用油气润滑的齿轮传动效果和最佳油气参数。通过设计5水平正交试验，分析了在不同转速、负载工况下，供油量、供气量和喷嘴高度对齿轮传动平台润滑效果的影响程度和齿面温度，进而获得最佳的水平设置和油气参数最优解，并与传统浸油润滑效果进行了对比试验。结果表明，供气量对油气润滑效果影响最大且存在最佳供气量；供油量影响次之；适当增加供油量有利于润滑，但超过一定数值后润滑效果提升有限；喷嘴高度影响最小，其数值存在最佳值，为保安全可将喷嘴适当远离啮合区放置。油气润滑降温效果好，其传动效率在相同载荷工况下优于浸油润滑。本文的研究可对油气润滑在齿轮传动中的应用提供技术指导。

Abstract

In order to provide a feasible lubrication means under starved condition， the gear transmission effect and the optimal oil-air parameters using oil-air lubrication are explored. Through the design of a five-level orthogonal test， the lubrication influence degree and tooth surface temperature， which are caused by oil supply， air supply and nozzle height， are analyzed under different speeds and load conditions. Then the optimal level setting and optimal solution of oil-gas parameters are obtained. These parameters are used in a comparative test between oil-air lubrication and splash lubrication. The results show that the air supply has the greatest influence on the oil-air lubrication effect， and there is an optimal air supply quantity； the influence of oil supply is the second. An appropriate increase is conducive to lubrication， but the improvement of lubrication effect is limited after exceeding a certain value； the nozzle height has the least influence； however， the height has the optimal value. To ensure safety， it should be put away from the gear properly. Oil-air lubrication has good cooling effect， and the transmission efficiency is better than splash lubrication under the same load condition. This research could provide technical guidance for the application of oil-air lubrication in gear transmission.
