ABSTRACT:
A variable ratio transmission includes a differential gear assembly coupled to three separate shafts. One of the shafts is coupled to a prime mover and operates as an input shaft to the differential gear assembly. Another of the shafts is connected to a load and operates as an output shaft of the differential gear assembly. The third shaft is coupled to a controlled load that is controlled by the user to adjust the transmission ratio between the input shaft and the output shaft in a continuous manner.
