摘要： The present invention is directed to a unique gear set (10) including a conical involute pinion (14) and a mating face gear (12). The mating face gear has an axis (GA) whose location and orientation is usually configured as intersecting with or slightly offset from the pinion axis (PA). The pinion teeth (16) are formed as involute helicoids generated from a base cylinder. The mating face gear teeth are defined by the shape of the mating conical pinion teeth surface at the time when the two mating gears are specifically positioned so as to perform synchronous rotations about their respective axes of rotation. This arrangement allows the gears to mesh and transmit high torque at high speeds through an angle as required in helicopter transmissions and the like.
