ABSTRACT:
A speed reducing device which is capable of large speed reductions and torque multiplication in a single stage is disclosed. The device includes input and output shafts in axial alignment, together with a transformer gear component having primary and secondary gears which rotate together. The primary gear engages a fixed gear spline while the secondary gear engages a rotatable output gear spline. This combination of gears, together with an eccentric and counterweight mounted on the input shaft, provides a system having numerous advantages in the field of high-ratio mechanical power transmission.
