Abstract
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.
