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.

Epicyclic gear carrier assembly having an integrated lubrication pump

A 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.

Bearing apparatus for power transmissions

An example transmission includes a first pericyclic motion converter to wobble at an angle relative to a first reaction control member and a first output shaft gear. The first pericyclic motion converter having gear teeth to engage a portion of gear teeth at a circumference of the first reaction control member to provide a first gear mesh and to engage a portion of gear teeth at a circumference of the first output shaft gear to provide a second gear mesh. A second pericyclic motion converter wobbles at an angle relative to a second reaction control member and a second output shaft gear. The second pericyclic motion converter having gear teeth to engage a portion of gear teeth at a circumference of the second reaction control member to provide a third gear mesh and engage a portion of gear teeth at a circumference of the second output shaft gear to provide a fourth gear mesh.
