Abstract
A transmission comprising at least one rim 1 and at least one wheel 2. An outside surface of the wheel 2 is adapted to engage with an inside surface of the rim 1. The wheel 2 is rotatable about a first axis B and the rim 2 is rotatable about a second axis A. The second axis A is at a distance from the first axis B. The inside surface of the rim 1 has a cyclic polygonal shape with an angle between each adjoining side 4 of the polygon being greater than 90°. The outer surface of the wheel 2 has a cyclic polygonal shape with an angle between each adjoining side 6 of the polygon being greater than 90°. Each side 6 of the wheel 2 engaging with a side 4 of the rim 1 of equal length during rotation of said transmission.
