The invention provides a transmission providing a gear ratio between an input shaft and an output shaft. The transmission comprises an annulus ring, a sun wheel being rotatable around a central axis of the transmission, a planet carrier being rotatable around the central axis of the transmission, and a set of planet wheels, each wheel comprising a plurality of wheel segments with different diameters, the planet wheels being fixed in rotational bearings of the planet carrier and being arranged to rotate epicyclically around the central axis. The annulus ring and the sun wheel each interacts with one of the wheel segments e.g. via meshing toothed gear wheels. The gear facilitates various interaction means at different locations in the gear, and thus facilitates a potentially less noisy, lighter, smaller or stronger gear by use of a low amount of components. |
