6. The lubrication system of claim 4 wherein said first conduit lubricates said planetary gears.

7. The lubrication system of claim 4 further comprising a first spray bar disposed on said carrier.

8. The lubrication system of claim 7 wherein said second conduit passes lubricant to said spray bar.

9. The lubrication system of claim 7 wherein said first spray bar directs lubricant to a component disposed coaxially with said carrier.

10. The lubrication system of claim 7 wherein said first bearing has a third inner race and said second bearing has a third opening in registration with said third inner race and a third conduit for passing lubricant through said first spray bar.

11. The lubrication system of claim 10 wherein said third conduit passes lubricant to a component disposed radially forward of said carrier.

12. The lubrication system of claim 11 wherein said component is a tapered bearing.

13. The lubrication system of claim 4 wherein said components are any of a ring gear or a sun gear.

14. The lubrication system of claim 1 further comprising;

an arm mounted to a grounding structure and attaching to said first bearing for preventing said first bearing from rotating with said second bearing.

15. The lubrication system of claim 14 in which said arm is flexibly attached to said first bearing.

16. The lubrication system of claim 1 wherein an outer surface of the second bearing supports an inner surface of the stationary first bearing.

17. A planetary gear system for a jet engine comprises:

a planetary gear;

a sun gear;

a stationary ring gear;

a carrier in which said planetary gear is mounted, said carrier mounted for rotation about said sun gear; and

a lubricating system having a lubricant input,

a stationary first bearing receiving lubricant from said lubricant input said first beating having a stationary inner first race in which lubricant flows,

a second beating for rotation within said first bearing, said second beating having a first opening in registration with said inner first race such that lubricant may flow from said inner first race through said first opening into a first conduit, and

said first bearing has a second inner race and said second bearing has a second opening in registration with said second inner race and a second conduit for passing lubricant,

wherein the first conduit passes lubricant to a different part of the jet engine than a part where lubricant is passed through the second conduit.

18. The planetary gear system of claim 17 wherein said second bearing extends from said carrier along an axis.

19. The planetary gear system of claim 17 wherein said first conduit lubricates said planetary gear.

20. The planetary gear system of claim 17 further comprising a first spray bar disposed on said carrier.

21. The planetary gear system of claim 20 wherein said second conduit passes lubricant to said spray bar.

22. The planetary gear system of claim 21 wherein said first spray bar directs lubricant to any of said sun gear, said planetary gear or said ring gear.

23. The planetary gear system of claim 17 wherein said first bearing has a third inner race and said second bearing has a third opening in registration with said third inner race and a third conduit for passing lubricant from said third inner race through said first spray bar.

24. The planetary gear system of claim 23 wherein said third conduit passes lubricant to a tapered bearing outside of said carrier.

25. The planetary gear system of claim 17 further comprising:

a first gutter attaching to and disposed radially outwardly from said ring gear for capturing oil from said lubrication system.

26. The planetary gear system of claim 25 further comprising:

a second gutter attaching to and disposed radially outwardly from said ring gear for capturing oil from said lubrication system said second gutter being disposed axially from said first gutter.

27. The planetary gear system of claim 25 wherein said first gutter is attached to an oil reservoir.

28. The planetary gear system of claim 27 wherein said second gutter directs oil to said first gutter via an opening in said ring gear.
