Abstract
A planet gear assembly, including: a planet pin; a bearing comprising an inner race secured to the planet pin at a planet pin bearing end; a planet gear; and a compliant annular plate arranged to secure the planet gear to the planet pin. Compliance of the annular plate permits rotation of the planet gear when a planet gear axis of rotation is not coincident with an axis of rotation of a portion of the planet pin in the annular plate.
Claims17
A planet gear assembly, comprising:
- a planet pin;
- a bearing comprising an inner race secured to the planet pin at a planet pin bearing end;
- a planet gear;
- and
- a single compliant annular plate arranged to secure the planet gear to the planet pin, wherein compliance of the annular plate permits rotation of the planet gear when a planet gear axis of rotation is not coincident with an axis of rotation of a portion of the planet pin in the annular plate.

A geared planetary system comprising:
- a bearing disposed in a carrier and comprising an inner race;
- a planet pin comprising a planet pin bearing end fixed to the inner race;
- an annular plate fixed to the planet pin;
- and
- a planet gear fixed to a radially outermost surface of the annular plate,
- wherein the annular plate is arranged to deform when a planet pin bearing end axis of rotation is not the same as a preferred planet gear axis of rotation, and in response to a deformation of the annular plate an actual planet gear axis of rotation is positioned to be the same as the preferred planet gear axis of rotation and wherein the planet pin also deforms to aid in making the actual axis of rotation of the planet gear the same as the preferred planet gear axis of rotation.

A planet gear assembly, comprising:
- a planet pin;
- a bearing comprising an inner race secured to the planet pin at a planet pin bearing end;
- a planet gear;
- and
- a compliant annular plate disposed radially between the planet pin and the planet gear and arranged to secure the planet gear to the planet pin, the compliant annular plate through its compliance permits the planet gear to rotate about a planet gear axis of rotation that is different than a planet pin bearing end axis of rotation and wherein the planet pin is also compliant, and wherein compliance of the planet pin and compliance of the annular plate together permit the planet gear to rotate about the planet gear axis of rotation that is different than the planet pin bearing end axis of rotation.

- a bearing comprising an inner race secured to the planet pin at a planet pin bearing end;
- a planet gear;
- and
- a compliant annular plate arranged to secure the planet gear to the planet pin, wherein compliance of the annular plate permits rotation of the planet gear when a planet gear axis of rotation is not coincident with an axis of rotation of a portion of the planet pin in the annular plate and wherein compliance of the planet pin aids in permitting rotation of the planet gear when the planet gear axis of rotation is not coincident with the axis of rotation of a portion of the planet pin in the annular plate.
