Planetary gear system arrangement with auxiliary oil system |
摘要 |
In one exemplary embodiment, a gas turbine engine includes a fan, a speed reduction device driving the fan, and a lubrication system for lubricating components across a rotation gap. The lubrication system includes a lubricant input. A stationary first bearing receives lubricant from the lubricant input and has a first race in which lubricant flows. A second bearing for rotation is within the first bearing. The second bearing has a first opening in registration with said first race such that lubricant may flow from the first race through the first opening into a first conduit. The first bearing also has a second race into which lubricant flows. The second bearing has a second opening in registration with the second race such that lubricant may flow from the second race through the second opening into a second conduit. The first and second conduits deliver lubricant to distinct locations. |

1. A gas turbine engine comprising:
a fan; a speed reduction device driving said fan; a lubrication system for lubricating components across a rotation gap, the lubrication system including a lubricant input, a stationary first bearing receiving lubricant from said lubricant input and having a stationary first race in which lubricant flows, and a second bearing for rotation within said first bearing, said second bearing having a first opening in registration with said first race such that lubricant may flow from said first race through said first opening into a first conduit; and said first bearing also having a stationary second race into which lubricant flows, and said second bearing having a second opening in registration with said second race such that lubricant may flow from said second race through said second opening into a second conduit, with said first and second conduits delivering lubricant to distinct locations. |
