Centrifugal Patents (Class 184/70)
  • Patent number: 7686727
    Abstract: A lubrication system is provided for a planetary gear train. The system includes an oil supply that disperses oil to a thrust bearing. The thrust bearing purges the oil radially outward. A strategically placed molded cavity collects and channels the oil from the thrust bearing into the planet bearings. Features in a planet gear carrier and a planet gear face washer can form the oil flow path. The washer can have a further feature for expelling the oil after the planet bearings are lubricated. By using the planet gear end face washer, this arrangement allows for the cavity to be cast rather than machined to thereby reduce the cost of increasing the flow of oil into the planet bearings.

  • Patent number: 3937300
    Abstract: A replaceable lubricating cartridge, adapted for installation in the end of a hollow rotating shaft, gear or the like, comprises a housing having an outer annular wall with a first end closed by an end wall and the other end partially closed by a first and second partition. The first partition forming with the housing a first closed chamber portion therein and the second partition forming with the housing a substantially closed second chamber portion therein adapted to be filled with liquid lubricant. An opening through the second partition permits the lubricant to be expelled as needed.
