TRAVEL DEVICE
TRAVEL REDUCTION GEAR
The travel reduction gear is a third stage planetary gear
type.
The travel motor rotates propeller shaft (
7
). This rota-
tion power is transmitted to third stage carrier (
2
) and
ring gear (
1
) via first stage planetary gear (
8
), first
stage carrier (
6
), second stage sun gear (
5
), second
stage planetary gear (
9
), second stage carrier (
4
), third
stage sun gear (
3
), and third stage planetary gear (
10
).
Travel motor housing (
14
) is bolted to the track frame
and is also secured to ring nut (
12
) with third stage
carrier (
2
). Ring gear (
1
), drum (
13
), and sprocket (
11
)
are bolted to each other. Accordingly, when ring gear
(
1
) is rotated, drum (
13
) and sprocket (
11
) are rotated.
