Abstract
A gear wheel includes precisely two teeth. The gear wheel is mounted rotatably about a gear wheel axis and wherein, in a sectional plane arranged orthogonally to the gear wheel axis, the gear wheel has a cross-sectional surface, which is intersected in its geometric center by the gear wheel axis (12), which has in the region of both teeth (10a, 10b) its maximum extension (dmax) through the geometric center and which, offset in the circumferential direction with respect to the direction of maximum extension, has its minimum extension (dmin). The outer contour of the cross-sectional surface is formed convexly over the entire circumference.

1-15. (canceled)
A gear wheel, comprising:
- precisely two teeth, wherein
- the gear wheel is mounted rotatably about a gear wheel axis,
- in a sectional plane, which is arranged orthogonally to the gear wheel axis, the gear wheel has a cross-sectional surface,
- the cross-sectional surface is intersected in its geometric center by the gear wheel axis,
- the cross-sectional surface has in the region of both teeth its maximum extension (dmax) through the geometric center and, offset in the circumferential direction with respect to the direction of maximum extension, has its minimum extension (dmin), and
- the outer contour of the cross-sectional surface is formed convexly over the entire circumference.
A gear wheel arrangement, comprising:
- at least two gear wheels in cogging engagement, wherein
- a smaller or a smallest of the at least two gear wheels comprises:
- precisely two teeth, wherein
- the gear wheel is mounted rotatably about a gear wheel axis,
- in a sectional plane, which is arranged orthogonally to the gear wheel axis, the gear wheel has a cross-sectional surface,
- the cross-sectional surface is intersected in its geometric center by the gear wheel axis,
- the cross-sectional surface has in the region of both teeth its maximum extension (dmax) through the geometric center and, offset in the circumferential direction with respect to the direction of maximum extension, has its minimum extension (dmin), and
- the outer contour of the cross-sectional surface is formed convexly over the entire circumference.
The gear wheel arrangement as claim in claimed 24, wherein
- the gear wheel is helically geared with an overlap angle of at least 180°.
A transmission, comprising:
- a gear wheel arrangement, wherein the gear wheel arrangement comprises
- at least two gear wheels in cogging engagement, wherein
- a smaller or a smallest of the at least two gear wheels, comprises:
- precisely two teeth, wherein
- the gear wheel is mounted rotatably about a gear wheel axis,
- in a sectional plane, which is arranged orthogonally to the gear wheel axis, the gear wheel has a cross-sectional surface,
- the cross-sectional surface is intersected in its geometric center by the gear wheel axis,
- the cross-sectional surface has in the region of both teeth its maximum extension (dmax) through the geometric center and, offset in the circumferential direction with respect to the direction of maximum extension, has its minimum extension (dmin), and
- the outer contour of the cross-sectional surface is formed convexly over the entire circumference.
