PLANETARY GEAR SYSTEM FOR TURBOMACHINE

摘要

A planetary gear system (100) for a turbomachine includes a forward planetary gear assembly (101) including a plurality of forward planet gears (101a) meshed to a forward sun gear (101b) disposed on a power shaft (40) and a forward ring gear (101c) meshed to the forward planet gears and an aft planetary gear assembly (103) aft of the forward planetary assembly including a plurality of aft planet gears (103a) meshed to an aft sun gear (103b) disposed on the power shaft and an aft ring gear (103c) meshed to the aft planet gears. The system also includes a gear housing (105) disposed between the forward planetary gear assembly and the aft planetary gear assembly. The gear housing includes a stationary carrier (105a), wherein the forward and aft planet gears are rotatably mounted to the stationary carrier, and a mount (105b) extending radially from the stationary carrier that is connectable to a stationary portion (107) of the turbomachine.
