A motion transmitting means comprising an eccentrically supported carrier means which upon rotation of the eccentric, orbits such that devices carried thereby in equal spacing engage the teeth of a concentric and fixed internal toothed gear means, the load carrying engagement being substantially of an arc of approximately 90 DEG of the teeth, and means to translate orbiting motion to rotary output motion. The number of gear teeth exceeds by one or more the number of devices which engage the gear teeth.
