| Research Abstract |
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.
