Designing Cycloidal Gears

The tip of the gear tooth must penetrate the pitch circle of the other gear to mesh. We must cut notches in the other gear to clear the tooth tip. The sides of these notches must be conjugate to the addendum curve. These curves form the dedendum of the mating gear. In the case of cycloidal gears, the driven gear is the pinion and the dedendum ...
