  • Patent number: 11162535
    Abstract: A bearing system includes bearing unit and a side-jet injector. The bearing unit includes an outer race, a plurality of internal rotating components, and an inner race. The side-jet injector includes an injector for delivering a lubrication source to the plurality of rotating components to withdraw heat generated and lubricate the bearing unit during operation of the bearing system.
    Type: Grant

    Inventors: Phillip H. Burnside, Andrew Schwendenmann
  • Patent number: 10731558
    Abstract: A circumferential lubricant scoop for providing lubricant to a bearing assembly. The scoop is disposed circumferentially about and rotates with a rotor shaft. The scoop comprises a plurality of lubricant capturing vanes shaped to capture and retain lubricant in a cavity behind a lower lip of the vane. This cavity is in fluid communication with channels leading to fluid pathways of an inner race of the bearing assembly. Fluid is moved through the channels and fluid pathways due to the rotational force imparted by the rotating rotor shaft.

  • Patent number: 10527098
    Abstract: Systems and methods are presented for directing oil to a bearing of a rotatable shaft. A system comprises a bearing race, a nozzle, and an oil catcher. The bearing race defines a first radial passage and a second radial passage axially displaced from the first radial passage. The nozzle is arranged to eject a stream of oil under pressure toward the shaft. The oil catcher is positioned between the bearing race and the shaft. The oil catcher comprises an annular catching flange at least partly defining a catchment region. The oil catcher defines a first channel extending from the catchment region to the first radial passage of the bearing race and a second channel extending from the catchment region to the second radial passage of the bearing race.
