The present invention is directed to a unique gear set including a conical involute pinion and a mating face gear. The mating face gear has an axis whose location and orientation is usually configured, as intersecting with or slightly offset from the pinion axis. The pinion teeth 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 that 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.

[ What is claimed is:] [1.] A gear set capable of meshing to transmit high torque at high speed through an angle, comprising:a conical involute pinion gear having a plurality of pinion teeth of similar shape to each other, with each pinion tooth having a pair of spaced-apart flank surfaces each formed as an involute helicoid;a mating face gear having a plurality of gear teeth of similar shape to each other, with each gear tooth having a pair of spaced-apart flank surfaces wherein the shape of the flank surfaces of the gear teeth are directly defined by the mating conical involute pinion tooth surfaces at the time when the two mating gear members are specifically positioned relative to one another so as to perform synchronous rotations about their respective axes of rotation, with the pinion gear having a taper angle relative to the pinion axis of rotation that is less than a taper angle of the face gear relative to the gear axis of rotation, whereby the flank surfaces of the face gear teeth contact the corresponding flank surfaces of the mating pinion gear along an instantaneous line of contact at every instant of the meshing cycle and follow true conjugate action during the whole meshing cycle.
