Planetary gearing with tapered disc - describing circle cut by all flanks of coaxial discs' teeth upon conical shaped revolution

摘要

The planetary gearing has a revolving toothed tapered disc engaging at least two other toothed co-axial discs. The radial plane of the tapered disc enclosed an angle beta with the radial plane of the co-axial discs. The interfaces of the discs have outer teeth unequal in number. The teeth are on conical surfaces and are triangular or trapezoid in shaped. All the flanks of the co-axial discs' teeth cut points lying on a circle around the axis of the discs. One point of the tapered disc describes this circle upon a conical shaped revolution. All flank lines of the tapered disc's teeth cut this circle-describing point.
