1-12. DRIVE SYSTEM
a.
The drive system consists of the reduction drive and accessory drive assemblies. The reduc-
tion drive assembly reduces the rotational speed of the turbine to the speeds necessary to drive the engine
accessories and driven equipment. The input pinion (A) of the turbine assembly, splined to the rotor shaft,
drives three planetary gears (B) that are mounted in carrier (C).
b.
The planetary gears (B) drive an internally splined ring gear (D) mounted on a splined
output shaft (E).
c.
The output shaft drives the oil pump gear (F) and the idler gear (G). The idler gear (G) in
turn drives the accessory drive assembly gears, gear (H), idler gear (I) and starter gear (J).
