ABSTRACT:
The invention is a drive for transducing rotation of a motor shaft having a multiple eccentric journal having a hollow sized to fit over the motor shaft and at least one pair of journals, each member of a pair being concentric with an axis parallel to the axis of the hollow and spaced apart from its mate an equal distance on opposite sides of and coplanar with a hollow axis. The eccentric journal is secured to the motor shaft and a rotational bearing is attached to each journal. Associated with each bearing is a transmission wheel having means for mounting the wheel to the bearing eccentrically with respect to the transmission wheel an equal radial amount from the axis of rotational symmetry of each transmission wheel as compared to the other transmission wheel. The invention provides a high ratio, single stage transmission with few moving parts, and without complicated case, lubrication or torque arms.
