Abstract
A planetary gear comprising a central, rotatable input/output shaft (), an elastic outer ring () which when being elastically deformed encloses and presses at least three planet wheels () in the form of rollers radially against a centrally mounted sun shaft (), which extends axially in alignment with the input/output shaft (). The planet wheels () have central holes and are rotatably mounted on stays (), the centre lines of the stays () being parallel with the sun shaft (). At least two () of the planet wheels have substantially coinciding centres with the stays () associated with the planet wheels (), while the planet wheel or other planet wheels () as well as the associated stay or stays () is/are constructed such that the centre lines of the stays are positioned a given distance closer to the sun wheel () than the axes of the planet wheels () when the planet wheels () engage the sun shaft (). This results in an optimum transfer of moment, while achieving an accurate positioning of the sun shaft as well as the planet wheel or the other planet wheels against the at least two planet wheels having centres which coincide with the respective stays.
