Abstract
A gear system is provided for a wheel of a tractor. The gear system includes a plurality of planet gears and a plurality of rollers. The planet gears are operable to rotate to provide tractive force to the wheel. The rollers are operable to abut against an inner ring of the wheel to reduce a contact force from the wheel contacting a channel on the plurality of planet gears.
Claims20
A gear system for a wheel of a tractor, the gear system comprising:
- a plurality of planet gears operable to rotate to provide tractive force to the wheel;
- and
- a plurality of rollers operable to abut against an inner ring of the wheel to reduce a contact force from the wheel contacting a channel on the plurality of planet gears,
- wherein the plurality of rollers receive a brunt of a contact force, thereby reducing the contact force on the plurality of planet gears,
- wherein the inner ring is closer to an outer surface of the wheel than the plurality of planet gears.

A drive arm for a tractor, the drive arm comprising:
- a wheel operable to propel the tractor along a channel;
- a drive train operable to cause the wheel to rotate;
- and
- a gear system coupled with the drive train and the wheel, the gear system comprising:
- a plurality of planet gears operable to rotate to provide tractive force to the wheel;
- and
- a plurality of rollers operable to abut against an inner ring of the wheel to reduce a contact force from the wheel contacting a channel on the plurality of planet gears,
- wherein the plurality of rollers receive a brunt of a contact force, thereby reducing the contact force on the plurality of planet gears,
- wherein the inner ring is closer to an outer surface of the wheel than the plurality of planet gears.
