TRAVEL MOTOR
Reduction gears
The reduction gears consist of two simple planetary
stages connected in series. Each planetary stage
consists of a sun (input) gear, an internal tooth ring
gear and planet gears mounted on a carrier. The sun
gear “floats
”
within the planet gears so as to attain
uniform load distribution at the multiple gear mesh
points.
The motor drives the 1st stage sun gear (1) which in
turn drives the 1st planet gears (2). Since these planet
gears (2) are engaged with the ring gear (3), the rota-
tion is transmitted to the 1st stage carrier (4).
The 1st stage carrier (4) is coupled directly to the
2nd stage sun gear (5) which in turn drives the 2nd
planet gears (6).
The 2nd stage carrier (7) is a part of the motor hous-
ing (non-rotating) and thus the main torque is output
to the ring gear (3). The output flange rotation is op-
posite to the input rotation.
