ABSTRACT:
A Benesch transmission transmits power from an input shaft to an output shaft, wherein the input shaft defines a first axis and the output shaft defines a second axis, includes a first member including a contacting surface which extends along at least a portion of a circle. The first member is coupled to the input shaft such that, upon rotation of the input shaft about the first axis, the first member moves so that a central axis of the circle orbits the first axis, and wherein a distance between the central axis and the first axis is variable. A plurality of second members are coupled to the output shaft and extend away from the second axis. Each of the second members extends within the circle such that, upon motion of the first member relative to the first axis, contact between the contacting surface and the second members causes rotation of the output shaft about the second axis.
