Abstract: The present invention relates to a bevolute gearing system which transmits torque between non-intersecting shafts at right angles to each other. The bevolute gear system includes a pinion gear which is flat and in one plane. The pinion gear is designed to include teeth which are shaped in the form of an involute spiral. The bevolute gear system includes a second gear which is also designed to include teeth which are shaped in the form of an involute spiral. The second gear is mounted on a non-intersecting axis at a right angle to the axis of the pinion gear. The bevolute gearing system of the present invention reduces the thrust loads to negligible values for the bearings of both the pinion gear and the second gear. In addition,. higher mechanical efficiencies, wider tolerances on alignment of the gears, interchangeability between the gear and the pinions to produce different ratios and a substantially eliminated gear noise are a few of the many advantages disclosed in the present invention.
