Rotation
of
the spiral bevel pinion is transmitted
to
the 37T spiral bevel gear (3), 10T final gear shaft (4), 66T final
gear (7) and differential case (1).
When road resistance to the right and left wheels are equal. differential pinions (2), (8) and differential side gears
(5), (9) all rotate as a unit. Both rear axles received equal input, and both wheels turn at the same speed, allowing the
tractor to go straight ahead.
At this time. differential pinions (2), (8) do not rotate around the differential pinion shaft (6).
2.
During Turning
When the tractor turns. the road resistance to the inside tire increases.
In
other words, if one
of
tires slows down,
revolution difference is generated in the differential side gears (5). (9). When rotation
of
one differential side gear
becomes lower than the other, differential pinions (2), (8) begin rotating around differential pinion shaft (6). The other
differential side gear is increased
in
speed by the speed increment
of
differential pinion shaft (6). This means that
rotation
of
one rear axle is slowed down and that
of
the other rear axle is increased. Thus, the tractor turn smoothly
without power loss.
The combined number
of
revolutions
of
the right and left differential side gears is always twice that
of
the spiral
bevel gear (3). When spiral bevel gear revolution is 100
min-
1
(rpm), and
if
one
of
the differential side gears stops
moving, the revolution
ofthe
other differential side gear becomes 200
min-
1
(rpm) and if one rotates at 50
min-
1
(rpm),
the other rotates at 150
min-
1
(rpm).
