Device for lubrication of bearing of rotating shaft of direct drive turboshaft engine for aircraft, has nozzle radially projecting lubricant, and support ring arranged to convey lubricant from supply conduit to nozzle during lubrication

摘要

The device (70) has a lubricant supply conduit (72) that is arranged for providing lubricant i.e. oil, to a set of bearings of a shaft of a turboshaft engine. The conduit is located inside a hollow fixed shaft (57) while performing lubrication. The supply conduit is arranged with a support ring (90). A nozzle (80) is arranged to radially project the lubricant towards outside of the fixed shaft on the set of bearings. The support ring is arranged to convey the lubricant from the supply conduit to the nozzle during lubrication. Independent claims are also included for the following: (1) a turboshaft engine (2) a method for assembly of a lubrication device.
