Unlike a regular involute tooth-gear, the "cycloidal disc," which is the gear for the Cyclo® Reducer, features a distinctively smooth curve.
A unique circular-arc tooth profile is also used for the internal gear. The smooth rolling contact that prevents tooth breakage results in a durable reducer with a long service life. (Some low reduction ratio models use helical gears and planetary gears.)
