ABSTRACT:
A rotatably shaft is directly supported by at least three wheels, including drive wheel. The circumferential edge of each of the wheels frictionally engages the circumferential edge of the shaft. The shaft is in frictional contact with each of the wheels, and is driven by the drive wheel. Speed step up is achieved because the diameter of the drive wheel is larger than the diameter of the shaft.
