ABSTRACT:
The power transmission comprises a drive guide shaft and a driven receiver shaft coaxial with the drive shaft, the two shafts having facing ends spaced axially from each other. A secondary shaft extends at an angle to the common axis of the drive and driven shafts, and a universal joint interconnects the facing end of the drive shaft to a first end of the secondary shaft, with the axis of symmetry of all three shafts intersecting at the geometrical center of the universal joint. A frusto-conical internal ring gear is rotatable with the driven shaft and a frusto-conical pinion is rotatable with the secondary shaft and meshes with the internal ring gear, the pinion being positioned intermediate the ends of the secondary shaft and the apices of the frusto-conical surfaces of the internal ring gear and the pinion intersecting the common axis at the geometrical center of the universal joint. A spacer, in a support rotatable with the driven shaft, is formed with an annular channel receiving and guiding the opposite end of the secondary shaft for revolving of the secondary shaft about the common axis of the drive and driven shafts, and an inertia element is integral with the secondary shaft for rotation therewith to regulate the speed thereof.
