摘要： A lubrication system for a transmission includes a flow-metering device and a controller. The controller is operatively associated with the flow-metering device to cause the flow-metering device to intermittently issue lubricant from the flow-metering device into a transmission based on an operating parameter of the transmission.

摘要： A transmission assembly including a transmission member and an oil distribution system. The transmission member includes a rotary pivot, and a pivot portion for pivoting about the rotary pivot; the oil distribution system is to receive oil feed and to transfer it to an oil reception chamber of the rotary pivot; the rotary pivot includes injection orifices putting the oil reception chamber into fluid flow communication with the gap between the rotary pivot and the pivot portion to form a fluid bearing; and the transmission assembly is for injecting oil into the gap at a first pressure into an outer portion of the gap, and at a second pressure into an inner portion of the gap, the second injection pressure being different from the first injection pressure.

摘要： A transmission includes an oil pipe disposed above a first gear group and a second gear group, the oil pipe having small holes. The oil pipe is formed integrally with a first restricting portion and a second restricting portion, the first restricting portion abutting against an inner surface of a first unit inside a case to thereby restrict an axial position of the oil pipe on an outside in one direction, and the second restricting portion abutting against an inner surface of a second unit to thereby restrict an axial position of the oil pipe on an outside in an other direction and rotation thereof.

摘要： A lubricating device of a gear apparatus for a vehicle lubricates a low-rotation-side gear and a high-rotation-side gear meshing with the low-rotation-side gear. The lubricating device comprises a first tooth surface lubricating oil supply part configured to supply a lubricating oil directly to a tooth surface position located more upstream of a rotating direction of the low-rotation-side gear than a meshing position of the low-rotation-side gear with the high-rotation-side gear so as to spray some of the lubricating oil from the tooth surface position toward a tooth surface of the high-rotation-side gear, and an in-shaft lubricating oil supply part configured to supply the lubricating oil into a shaft of the high-rotation-side gear.

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.

摘要： A planetary gear train is lubricated via a distribution ring and a planet gear carrier oil supply passage in communication with the distribution ring. The gear train includes a sun pinion that engages a planet gear at a sun planet gear mesh. The planet gear is rotatably mounted to a planet gear carrier. The planet gear carrier is configured to drive an output shaft. The output shaft may be operatively connected to a load. The planet gear rotates within a ring gear at a planet gear ring mesh. The distribution ring surrounds a planet gear carrier and has a hollow interior that communicates with an oil supply. A planet gear carrier oil supply passage may extend through a planet gear carrier of the gear train and supply oil to a sun planet gear mesh and the planet ring gear mesh, and bearings of the planetary gear train.
