Abstract

Claims (42)

1 . A gear having an input shaft and an output shaft, the gear comprising:

an outer wheel;

an inner wheel that is positioned concentrically in relation to the outer wheel;

a traction means extending between the outer wheel and the inner wheel;

a rotatable transmitter carrier that passes through the inside of the inner wheel; and

at least one revolving transmitter positioned on the rotatable transmitter carrier and configured to lift the traction means from an outer periphery of the inner wheel and push the traction means onto an inner periphery of the outer wheel,

wherein the at least one revolving transmitter is provided eccentrically from the rotation axis of the transmitter carrier.

2 . The gear of claim 1 , wherein the input shaft is connected to the at least one revolving transmitter.

3 . The gear of claim 1 , wherein the input shaft is connected to the outer wheel.

4 . The gear of claim 1 , wherein the input shaft is connected to the inner wheel.

5 . The gear of claim 1 , wherein the output shaft is connected to the inner wheel.

6 . The gear of claim 1 , wherein the output shaft is connected to the at least one revolving transmitter.

7 . The gear of claim 1 , wherein the output shaft is connected to the outer wheel.

8 . The gear of claim 1 , wherein the at least one revolving transmitter is provided by an inner part of a wire race bearing.

9 . The gear of claim 1 , wherein the at least one revolving transmitter is provided by a wire race bearing.

10 . The gear of claim 1 , wherein the traction means is made from plastic or rubber, which is provided on a metal meshing or a woven or non-woven fabric.

11 . The gear of claim 1 , wherein the gear has a three-row gear design further comprising a second pair of wheels and a third pair of wheels located in different axial planes, each pair of wheels comprising an inner wheel and an outer wheel.

12 . The gear of claim 1 , wherein a transmitter carrier with at least one revolving transmitter is located in a third axial plane between a first pair of wheels and a second pair of wheels, each pair of wheels comprising an inner wheel and an outer wheel.

13 . A moto-gear unit with the gear of claim 1 , wherein an electric motor is provided, a rotor of the electric motor being connected to the input shaft of the gear.

14 . An electric generator with a drive unit and with a generator unit and with the gear of claim 1 , the input shaft of the gear being connected to the drive unit and the output shaft of the gear being connected to an input shaft of the electric generator.

15 . A gear assembly comprising:

a three-row gear design comprising:

a first pair of wheels,

a second pair of wheels, and

a third pair of wheels, wherein the third pair of wheels is located in a different axial plane than the second pair of wheels, and

wherein each pair of wheels comprises:

an inner wheel defining an outer periphery;

an outer wheel defining an inner periphery, the outer wheel positioned outwardly relative to the inner wheel;

a traction means extending between the outer wheel and the inner wheel; and

a revolving transmitter configured to move the traction means from the outer periphery of the inner wheel to the inner periphery of the outer wheel.

16 . The gear assembly of claim 15 , wherein the traction means is a flexible belt with teeth on both sides.

17 . The gear assembly of claim 15 , further comprising:

an input shaft connected to the inner wheel; and

an output shaft connected to the revolving transmitter.

18 . A gear assembly comprising:

a first pair of wheels and a second pair of wheels, wherein each comprises an inner wheel and an outer wheel positioned outwardly relative to the inner wheel,

wherein the first pair of wheels is located in a first axial plane and the second pair of wheels is located in a second axial plane;

a traction means extending between the outer wheel and the inner wheel;

a transmitter configured to move the traction means from the inner wheel to the outer wheel; and

a transmitter carrier with at least one revolving transmitter, wherein the transmitter carrier is located in a third axial plane between the first axial plane and the second axial plane.

19 . The gear assembly of claim 18 , further comprising a transmitter carrier located in a third axial plane between the inner wheel and the outer wheel, the transmitter carrier configured to carry the transmitter.

20 . The gear assembly of claim 18 , wherein the traction means is a flexible toothed belt, and the transmitter is a revolving transmitter that lifts the traction means from an outer periphery of the inner wheel and pushes the traction means onto an inner periphery of the outer wheel.
