초록

The cost and bulk of a speed reducing transmission required to provide low speed rotational power from a gas turbine engine is avoided by employing bearings (16, 18) jornalling a high speed shaft (12) of the engine with a power takeoff in the form of a tubular shaft (62) having bearing receiving and retaining openings (82) to act as a bearing cage for bearing elements (64, 66) disposed between inner and outer bearing races (68, 70). Upon rotation of the high speed shaft (12), the bearing elements (64, 66) will move in an epicyclic fashion thereby driving...

청구항

A power plant comprising: a gas turbine engine having a high speed output shaft; at least one bearing journalling said shaft and having a bearing cage rotatable relative to said shaft at a speed less than said high speed, said bearing cage being driven by substantially epicyclic movement of bearing elements of said bearing when said high speed shaft is driven; and a load coupled to said bearing cage to be driven thereby.
