摘要： An example transmission comprising a lubricant feed passageway to receive lubricant; an input shaft having a cavity that defines a shaft collection trough to receive the lubricant from the lubricant feed passageway, the input shaft defining a radial passageway to enable the lubricant to flow from the shaft collection trough to an exterior surface of the input shaft; and a carrier to receive at least a portion of the input shaft, the carrier defining a carrier collection trough and channels formed in the carrier to distribute the lubricant to at least one of rotating components or non-rotating components in the carrier, the carrier collection trough to receive the lubricant from the shaft collection trough via the radial passageway in response to the input shaft rotating.

摘要： Reversely identical transmissions for a tiltrotor aircraft may include reconfigurable gearbox lubrication systems to accommodate operation in either direction of propeller rotation, using common parts. In a typical installation, at least two separate winged tiltrotor transmissions may operate with opposing propeller rotations. Common parts of the two transmissions may include cast housings, rotor shafts, pinion gears, lubrication sump tanks, lubrication pumps, and lubrication filter manifolds including filters having reversible orientations. Either transmission configuration may be utilized on either the left or right side of a tiltrotor aircraft by swapping the lubrication sump tank and lubrication filter manifold locations on the gearbox. In addition, a plug may be used to manually reconfigure an opposite lubrication oil path to accommodate first and second rotational directions of the lubrication pump.

摘要： A mechanical power transmission that pivots about an axis to vary an angle between an input shaft and an output shaft. The mechanical power transmission includes an input gear having an input shaft that couples to a drive shaft, an output gear having an output shaft that couples to a tail rotor, a first intermediate gear rotationally coupled to the input gear, and a second intermediate gear rotationally coupled to the output gear. The mechanical power transmission further comprises a shaft that mechanically couples the first intermediate gear with the second intermediate gear, where a centerline of the shaft is coincident with the axis.

摘要： A mechanical power transmission is described that pivots about an axis to vary an angle between an input shaft and an output shaft. In one embodiment, the mechanical power transmission includes an input gear having an input shaft that couples to a drive shaft, an output gear having an output shaft that couples to a tail rotor, a first intermediate gear rotationally coupled to the input gear, and a second intermediate gear rotationally coupled to the output gear. The mechanical power transmission further comprises a shaft that mechanically couples the first intermediate gear with the second intermediate gear, where a centerline of the shaft is coincident with the axis.

摘要： Power transmissions are disclosed. An example transmission includes a first pericyclic motion converter having a first aperture to receive at least a portion of an output shaft and a second pericyclic motion converter having a second aperture to receive at least a portion of the output shaft. A first bearing is positioned between an inner surface of the first pericyclic motion converter defined by the first aperture and an outer surface of the output shaft. A second bearing is positioned between an inner surface of the second pericyclic motion converter defined by the second aperture and the outer surface of the output shaft.

摘要： Compressors having multi-speed gearboxes are disclosed. The apparatus comprises: a fluid channel to convey a fluid, a compressor fluidly coupled to the fluid channel, a gearbox operatively coupled to the compressor, the gearbox to control the compressor using a first gear ratio and a second gear ratio different from the first gear ratio to vary a flow rate of fluid in the fluid channel, and clutches to vary the gearbox between the first gear ratio and the second gear ratio.
