Abstract: A gear arrangement for a high reduction of the input rotational velocities is achieved in a single reduction gear train, utilises a long narrow driving pinion (12) located between two idler pinions (13) to mesh with the teeth of both, and the teeth of both idler pinions (13) mesh with teeth (14) of a year wheel, thereby sharing the load of the idler pinions (13), which can be of nylon for providing a quiet gear train.
