ABSTRACT:
A rotary assembly which has an inner shaft and an outer hollow cylinder coaxially surrounding and freely rotatable with respect to the inner shaft. A drive shaft is coaxial with the inner shaft and is freely rotatable with respect thereto, this drive shaft carrying an inner gear which rotates with the drive shaft. An intermediate gear meshes with the inner gear, and this intermediate gear is mounted directly on the inner shaft for free rotation with respect thereto. A circumferential gear transmission which is coaxial with the inner shaft and the outer cylinder meshes with the intermediate gear and is operatively connected with the cylinder to transmit rotation thereto from the intermediate gear which is driven by way of the inner gear from the rotary drive shaft.
