However, unlike e.g. the spiral Nautilus Gears or elliptical gears, the gearing ratio is one-to-one without any accelerations or decelerations. Also One-to-Two gears are provided, based on the same concept. All gear teeth have an involute shape, which assures their smooth rolling. Copyright (c) 2026, M. Oskar van Deventer.
