REDUCTION GEAR (Planetary two-stage)
Refer to the cross section.
The motor shaft (1) is coupled to the drive gear (2) via a spline. The drive force of the hydraulic
motor is transmitted from the drive gear (2) to the engaged planetary gear (3). The planetary gear
(3) is meshed with the ring gear of the reduction gear housing (4). Thus, while rotating, it revolves
around the ring gear. The planetary gear (3) is held by the holder (5) via the bearing and the holder
transmits the revolving motion of the planetary gear (3) to the sun gear (6) coupled via the spline.
The sun gear (6) meshes with the planetary gear (7) and as with the first stage, transmits the
rotary motion to the planetary gear (7). Since the planetary gear (7) is meshed with the ring gear of
the housing (4), it revolves while rotating. Since the planetary gear (7) is held by the holder (8) via
the bearing, the holder (8) transmits the revolving motion of the planetary gear (7) to the pinion shaft
(9) coupled via the spline.
