摘要： A lubrication assembly and operating method are provided herein. The lubrication assembly includes a rotating component an axial recess positioned on an axial side of the rotating component, and a lubricant conveyor that remains stationary relative to the rotating component and extends into the axial recess to form a gap between axial recess and the first lubricant conveyor. The lubricant conveyor directs a lubricant toward the axial recess during rotation to generate a lubricant spray focused in a targeted direction.

摘要： A planet carrier for a mechanical gearbox for a turbomachine includes a one-piece cage that extends about an axis of rotation defining an internal housing configured to receive a sun gear and planet gears of the gearbox. The planet carrier further includes a lubrication system with at least one bore formed in the cage and extending parallel to the axis over more than 30% of a maximum axial dimension (Lmax) of the cage. The lubrication system also includes for the at least one bore, at least two sprinklers which are fitted to the cage and which are each mounted in a recess of the cage.

摘要： The present invention relates to a drive for reaching a desired position of a component such as of a rotor blade, a crane tower, a superstructure and the like, having at least two drive elements that are in toothed engagement with one another and of which at least one is drivable from a drive source and the other is connectable to the component, and having a lubricating device for lubricating the drive elements, wherein at least one lubricant passage for the supply of lubricant to a meshing tooth pair is led through one of the drive elements. It is proposed to effect the supply of the lubricant by a distributor that is connected upstream of the lubricant passage integrated in the drive element and to control the connection between a supply passage of the distributor and the at least one lubricant passage integrated in the drive element by a relative movement between the drive element and the distributor.

摘要： A geared architecture includes a carrier that has spaced apart walls with circumferentially spaced mounts that interconnect the walls. The mounts provide circumferentially spaced apart apertures between the mounts at an outer circumference of the carrier. A sun gear and intermediate gears are arranged about and intermesh with the sun gear. The intermediate gears are supported by the carrier. The intermediate gears extend through the apertures to intermesh with a ring gear. A baffle is supported relative to the carrier and includes a lubrication passage near at least one of the sun gear and intermediate gears for directing a lubricant on the at least one of the sun gear and intermediate gears. The lubrication passage includes a primary passage that extends laterally between the walls and first and second passages and is in communication with the primary passage and respectively terminates near the sun gear and intermediate gears.

摘要： A lubrication system includes an additive and a delivery system. During normal operational conditions, the lubricating oil circulating in the transmission system is collected and contained in a secondary oil reservoir to retain a quantity of the lubricating oil for use in an oil-out condition. When an oil-out condition is detected, the additive is injected and mixed with the collected lubricating oil in the secondary oil reservoir or dispersed directly into a power transmission gearbox housing to enhance the characteristics of the lubricating oil and increases the operational time period of the power transmission gearbox during an oil-out condition.

摘要： A triple circuit lubrication device for lubricating a mechanical system, the lubrication device being provided with two independent lubrication circuits, a tank common to both lubrication circuits and containing a lubrication liquid, and a tertiary circuit in which a tertiary liquid flows. Each lubrication circuit comprises pipes, and respective pressure sensors, pumps, heat exchangers, spray nozzles, and suction points for sucking up the lubrication liquid situated in the tank. The second suction point is situated below the high first suction point. The tertiary circuit comprises a third pump, a third pressure sensor, the second heat exchanger, and a third heat exchanger, thus serving to cool the lubrication liquid flowing through the second lubrication circuit.
