One-to-One Gears

This CAD model was designed by Oskar van Deventer, copyright (c), 28 January 2026

One-to-One gears is a demonstration of a gearing system where each gear tooth is larger than its neighbour. 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.
