A planetary gear system and a method of fabricating same. The planetary gear system includes at least one planet gear, at least one planet pin receiving the at least one planet gear, and a carrier. The carrier itself includes at least one carrier opening for accommodating the at least planet gear, at least one planet pin opening for receiving the at least one planet pin, and at least one flex portion within a wall of the carrier for providing enhanced compliance to the carrier in response to force directed on the at least one planet gear.

1. A planetary gear system, comprising: at least one planet gear;at least one planet pin receiving the at least one planet gear; anda carrier, comprising: at least one carrier opening for accommodating the at least one planet gear;at least one planet pin opening for receiving the at least one planet pin; andat least one flex portion within a wall of the carrier for providing enhanced compliance to the carrier in response to force directed on the at least one planet gear. 2. The planetary gear system of claim 1, wherein the carrier comprises a first part and a second part and the at least one flex portion comprises a neck portion, a ring portion and a gap between the neck portion and the ring portion and the wall of the carrier. 3. The planetary gear system of claim 1, wherein each of the at least one flex portions comprises a carrier ring, a carrier stabilizer and a ring gap, the ring gap serving as the at least one planet pin opening. 4. The planetary gear system of claim 1, wherein the at least one flex portion is sited adjacent to the at least one planet pin opening. 5. The planetary gear system of claim 4, wherein each of the at least one flex portions comprises a flex line and at least one flex cavity. 6. The planetary gear system of claim 4, wherein each of the at least one flex portions comprises a pair of flex channels and a flex connector formed in the carrier wall. 7. The planetary gear system of claim 6, wherein the flex connector connects with each of the pair of flex channels. 8. The planetary gear system of claim 4, wherein each of the at least one flex portions comprises a flex indent and a carrier flex surface. 9. The planetary gear system of claim 4, wherein each of the at least one flex portions comprises a flex moat. 10. The planetary gear system of claim 4, wherein each of the at least one flex portions comprises a plurality of flex slits. 11. The planetary gear system of claim 4, wherein each of the at least one flex portions comprises at least one inner opening and at least one outer opening. 12. The planetary gear system of claim 4, wherein each of the at least one flex portions comprises at least one inner window and at least one outer window. 13. The planetary gear system of claim 4, wherein each of the at least one flex portions comprises: a carrier flex surface;a flex indent; anda plurality of orifices within the carrier wall. 14. A method of fabricating a planetary gear system, comprising: providing a carrier having at least one planet pin opening;providing a planet pin for accommodation within the at least one planet pin opening;forming at least one flex portion within the carrier; andinstalling at least one planet gear adjacent to the at least one flex portion. 15. The method of claim 14, wherein the providing a carrier comprises providing a carrier having a first part and a second part and wherein the forming at least one flex portion comprises forming at least one flex portion in one or both of the first and second parts. 16. The method of claim 14, wherein the forming at least one flex portion comprises removing some material from a wall of the carrier adjacent the at least one planet pin opening. 17. The method of claim 16, wherein the removing some material forms a flex line and at least one flex cavity; a carrier ring, carrier stabilizer, and at least one ring gap; a pair of flex channels and a flex connector; a carrier flex surface and a flex indent; or, a flex moat. 18. The method of claim 16, wherein the removing some material forms a plurality of flex slits; at least one inner opening and at least one outer opening; at least one inner window and at least one outer window; or, a carrier flex surface, a flex indent, and a plurality of orifices.
