润滑油路系统、轴承共腔结构、燃气涡轮发动机
摘要：
本发明涉及一种用于相邻布置在中心轴上的至少两个轴承的润滑油路系统，包括：用于第一轴承的第一轴承润滑油路；和用于第二轴承的第二轴承润滑油路，第一轴承和第二轴承彼此相邻、且第二轴承相较于第一轴承更靠近中心轴的端部，其中：第一轴承润滑油路和第二轴承润滑油路的润滑油腔共腔布置，润滑油腔的上部与油气出口连通，润滑油腔的下部与润滑油回油口连通，来自第一轴承和第二轴承的润滑油均流向所述润滑油回油口。本发明还涉及一种具有上述润滑油路系统的燃气涡轮发动机。
摘要（英）：

The invention relates to a lubricating oil passage system for at least two bearings adjacently disposed on a center shaft. The system comprises a first bearing lubricating oil passage for a first bearing and a second bearing lubricating oil passage for a second bearing; the first bearing is adjacent to the second bearing, the second bearing, comparing with the first bearing, is disposed closer to the end of the central shaft; a lubricating oil chamber of the first and the second bearing lubricating oil passages is a co-chamber, the upper portion of the lubricating oil chamber is communicated with an oil-gas outlet, the bottom of the lubricating oil chamber is communicated with a lubricating oil returning opening, and lubricating oil from the first bearing and the second bearing flows into the lubricating oil returning opening. The invention further relates to a gas turbine engine with the lubricating oil passage system.
