The rotating motion of the hydraulic motor is transmitted to drive gear (121) of 1st stage, and the
drive gear rotate planetary gears (R, 117). Then planetary gears (R, 117) revolves inside fi xed hub
(105). This rotation becomes the output of 1st stage and is transmitted to carrier No.1 and sun gear
(114). Similarly the revolution of planetary gears (F, 108) are transmitted to spindle (101). Then plan-
etary gears (F, 108) do not revolve, but rotate to hub (105). Therefore, the rotating case is driven by
the overall driving torque of hub (105).
This reduction ratio is expressed as shown below :
·
Reduction ratio (I) = (Hub teeth / Drive gear teeth + 1) x (Hub teeth / Sun gear teeth + 1) - 1
