<p>#CMT# #/CMT# 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. #CMT# : #/CMT# Independent claims are also included for the following: (1) a turboshaft engine (2) a method for assembly of a lubrication device. #CMT#USE : #/CMT# Device for lubrication of a bearing of a rotating shaft of a turboshaft engine (claimed) i.e. direct drive turboshaft engine, utilized for an aircraft. #CMT#ADVANTAGE : #/CMT# The support ring is arranged to convey the lubricant from the supply conduit to the nozzle during lubrication, thus allowing the lubrication device to have a relatively simple design with limited mass and obstruction due to the presence of nozzle, while preserving modularity of the receiver of the turboshaft engine. The device limits obstruction of the engine and the complexity of the device is not increased. The weight of the engine is limited. The fixed shaft is assembled in an easy manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a hollow fixed shaft of a lubrication device according to a longitudinal median plane for providing lubricant supply. 57 : Hollow fixed shaft 70 : Device for lubrication of a bearing of a rotating shaft of a turboshaft engine 72 : Lubricant supply conduit 80 : Nozzle 90 : Support ring.</p> |
