ABSTRACT:
The invention is an infinitely variable transmission having a frusto-coni impeller mounted on a block alongside a frusto-conical roller, the smaller end of the impeller being opposite the larger end of the roller. The transmission includes a wheel translatable along the impeller and roller, the wheel contacting both the impeller and roller in a selected set of wheel positions so that the wheel transfers rotary motion of the impeller to the roller. The transmission includes a mechanism to adjust the translation path of the wheel to compensate for wheel wear and a mechanism to vary the pressure with which the wheel contacts the impeller and roller.
