Verification of Lubrication and Cooling Effects of MQL System for Gear Transmission

从环境角度看，齿轮传动系统应采用最小数量润滑方法。本研究旨在寻找一种可靠的MQL方法和高速行驶条件下的齿轮设计方法。首先，应用离心式润滑法能够充分发挥润滑剂的冷却性能。其次，比滑移率为30%的齿轮比50%比滑动率的齿轮产生的热量要少。第三，将离心式润滑法与30%比滑移率的齿轮相结合，可有效降低齿轮传动系统的环境负荷。

From an environmental point of view, a MQL(Minimum Quantity Lubrication) method should be adopted to gear transmission systems. This study aims to find a reliable MQL method and a gear design method under high-speed driving conditions.The conclusions we have obtained are as follows. First, the application of centrifugal lubrication method is able to pull out the full cooling performance of the lubricant. Second, the operation of gears with 30% specific sliding shows less heat generation than that of gears with 50% specific sliding. Third, combining the centrifugal lubrication method and the gears with 30% specific sliding is effective for reducing an environmental load of gear transmission systems.
