Abstract

A gearbox is disclosed. The gearbox can have planetary gears. Each planetary gear can revolve around a rotational center of itself while concurrently revolving around a rotational center of the gear system as a whole. The gearbox can be used to deliver rotational output energy at a right (or other angle) from the direction of a received input energy.

Claims (12)

1. A gearbox device comprising:

a planetary gear having a first tooth and a second tooth, wherein the first tooth and the second tooth are on the radial outside of the planetary gear, and wherein the first tooth has a larger radius from a planetary gear rotational center than the second tooth, and wherein a diameter of the first tooth decreases along a transverse direction, and wherein the planetary gear further comprises a third tooth that has a third top land, and wherein the third top land has a decreasing radius from the planetary gear rotational center along the length of the third tooth.

2. The device of claim 1 , wherein the first tooth is on a first longitudinal side of the second tooth, and wherein the third tooth is on a second longitudinal side of the second tooth, and wherein the third tooth has a radius from the rotational center of the planetary gear that is less than the radius of the second tooth from the rotational center of the planetary gear.

3. The device of claim 1 , wherein the third tooth has a radius from the rotational center of the planetary gear that is equal to the radius of the first tooth from the rotational center of the planetary gear.

4. A gearbox device comprising:

a planetary gear having a first tooth and a second tooth, wherein the first tooth and the second tooth are on the radial outside of the planetary gear, and wherein the first tooth has a larger radius from a planetary gear rotational center than the second tooth, and wherein a diameter of the first tooth decreases along a transverse direction, and wherein the planetary gear comprises a magnet.

5. The device of claim 4 , wherein the magnet comprises an electro-magnet.

6. The device of claim 4 , wherein the magnet comprises a permanent magnet.

7. A gearbox device comprising:

a planetary gear having a first tooth and a second tooth, wherein the first tooth and the second tooth are on the radial outside of the planetary gear, and wherein the first tooth has a larger radius from a planetary gear rotational center than the second tooth, and wherein a diameter of the first tooth decreases along a transverse direction, and wherein the planetary gear comprises a toothless friction surface.

8. A gearbox device comprising:

a planetary gear having a first tooth and a second tooth, wherein the first tooth and the second tooth are on the radial outside of the planetary gear, and wherein the first tooth has a larger radius from a planetary gear rotational center than the second tooth, and wherein a diameter of the first tooth decreases along a transverse direction, and wherein the device has no sun gear.
