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.

A transmission includes at least one planetary gear stage with a planet carrier having a first toothing. The transmission further includes at least one lubricant line having a first outlet opening and a second outlet opening. The first toothing, together with a second toothing, forms a spline. The first outlet opening is configured to lubricate the spline, and the second outlet opening is configured to lubricate a sun gear of the planetary gear stage.

A line of vehicle transmissions is provided. The vehicle line includes a first multi-stage gear train assembly with at least two stages, a second multi-stage gear train assembly with at least three stages, and a housing including a first section removably attached to a second section. The second housing section is configured to receive the first and second multi-stage gear train assemblies in different product arrangements.

A gear assembly for an aeronautical engine includes a first gear disposed at a centerline axis of the gear assembly, a second gear coupled to the first gear in adjacent radial arrangement to form a first mesh between the first gear and the second gear, a static portion coupled to the second gear in adjacent circumferential arrangement, the static portion defining a pocket, and a spraybar disposed within the static portion such that a supply opening of the spraybar is directed at the first mesh between the first gear and the second gear. The supply opening provides a flow of lubricant to the first mesh between the first gear and the second gear and at least a portion of the flow of lubricant is collected by the pocket. The flow of lubricant is continuously released from the pocket to the gear system.

A continuously variable transmission is obtained by winding, around a drive sheave and a driven sheave, a continuously variable transmission belt in which a plurality of metal elements are stacked and supported on an endless ring. In at least one of the metal elements, flange parts are formed on a head part positioned at an outer peripheral side of the endless ring and a trunk part positioned at an inner peripheral side of the endless ring. The continuously variable transmission is provided with a fluid supply device which, during movement of the continuously variable transmission belt from the driven sheave to the drive sheave, sprayed lubricating oil in a movement direction of the continuously variable transmission belt, towards the flange parts.

A method of assembling a fan drive gear system includes the steps of installing spherical bearings into respective races to provide a plurality of bearing assemblies, mounting at least one of the bearing assemblies onto a corresponding shaft of a torque frame, each of the shafts fixed relative to one another, installing at least one gear onto at least one of the bearing assemblies, the gears meshing with a ring gear and a centrally located sun gear and grounding the torque frame to a static structure to prevent rotation of the torque frame.

A multi-component fluid distribution system includes a first substrate component having an inlet for receiving fluid and an internal channel for communicating lubricant. A second substrate component is interlocked to the first substrate component. The second substrate component includes an inlet to receive fluid from the first component. The fluid distribution system also includes an over-molded portion sealing a joint between the first and second substrate components. The fluid distribution system further includes at least one outlet nozzle connected to the second substrate component to discharge fluid to a predetermined fluid receiving component.

A planetary gearbox includes a planet carrier, with a planetary gear rotatably disposed on the planet carrier, and a gear that meshes with the planetary gear, as well as a gas turbine engine having such a planetary gearbox. The planet carrier has an oil supply installation including a supply line for oil to an opening. The oil is directed out of the opening in the direction of the planetary gear and/or the gear. The oil supply installation in relation to a primary rotating direction of the planetary gear and/or the gear in front of the opening includes a shielding region which protrudes from an external side of the oil supply installation and which by way of the external side of the oil supply installation on a side that faces the primary rotating direction of the planetary gear and/or the gear, delimits an oil collection groove.

An epicyclic gear train component includes 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 walls. Baffles are arranged between the walls near the mounts. Gear pockets are provided between the baffles and the baffles include a lubrication passage that terminates at least one of the gear pockets. One of the walls includes a hole which has a tube that extends through the hole and is received in an opening in the baffle. The tube is in communication with the lubrication passage.

An electromotive transmission device for a vehicle having an electric motor (2) comprising a stator winding (7) and a rotor (5). A drive shaft is driven by an input shaft (12) via a transmission. The transmission is arranged coaxially with the input shaft (12) and the electric motor (2). The stator winding (7) can be cooled by a cooling unit. The transmission has an annular support component, which is joined to the inner face of the radial end wall (11). Pressurized oil is supplied to a radially running annular passage (18) arranged in the end wall (11) and/or the annular support component. A plurality of spray outlets (19) are distributed around the circumference of the annular passage (18) or a radially running slot-like spray outlet. The spray or sprays from the spray outlets (19) are directed at the stator winding (7) and/or the rotor.
