Abstract
A transmission device includes a central wheel, a satellite wheel, a drive element and a tension control device. The central wheel is disposed to rotate about a central wheel axle that is fixed in a first position. The satellite wheel has a satellite wheel axle, which is movable with the satellite wheel relative to the fixed position such that the satellite wheel does not rotate about the satellite wheel axle. The drive element, which has a first portion and a second portion, connects the central wheel and the satellite wheel. When the satellite wheel revolves in a first direction around the central wheel, the central wheel is induced to rotate in a second direction opposite the first direction. The tension control device is connected to the drive element and controls its tension to at least partially compensate for the induced rotation of the central wheel.
