<p>The variable speed transmission includes a power input drive shaft and a variable throw crank having a zero throw position aligned with the input shaft. The variable throw crank is coupled to the input shaft for rotation therewith and its eccentricity with respect to the axis of rotation of the input shaft can be varied. A control plate, also referred to as a master link, is rotatably mounted on the crank and a plurality of clutches having input and out-put shafts are operatively connected to the control plate through a plurality of pitman type links, whereby the control plate oscillates the input shafts of the clutches upon rotation of the power input shaft and variable throw crank of the transmission. The outputs of the clutches are connected to an output shaft for the transmission. By varying the throw of the variable throw crank the ratio between the rotary speed of the output shaft can be infinitely adjusted from zero to a maximum ratio determined by the maximum eccentricity of the variable throw crank with respect to the axis of rotation of the input shaft. A preferred embodiment is to revert the above.</p> |
