PLANETARY GEAR SYSTEM AND CARRIER THEREFOR

摘要

A planetary gear system (100), comprising: a plurality of compound planet gears (106) configured to orbit around a primary rotation axis (110) and each including three gear stages; a first non-fixed annular gear (152) configured to rotate about the primary rotation axis (110) and operatively meshed with one of the three gear stages; a second non-fixed annular gear (154) configured to rotate about the primary rotation axis (110) and operatively meshed with one of the three gear stages; a fixed annular gear (132) with a central axis that is coaxial with the primary rotation axis (110) and operatively meshed with one of the three gear stages; and a non-fixed sun gear (104) configured to rotate about the primary rotation axis (110) and operatively meshed with one of the three gear stages.
