Cycloidal Speed Reducers

Cycloidal (planocentric) Gearboxes employ eccentric motion to achieve speed reduction. It uses non-circular or eccentric motion to convert input rotation into a wobbly cycloidal motion. This motion is then converted back into a circular output rotation. During this process, speed reduction occurs.

Unlike strain wave gearing which employs a flexible cylinder that doesn’t move in its entirety but stretches to mesh with the internal circular spline gear to achieve a type of cycloidal motion, the cycloidal (planocentric) drives will actually move the entire internal gear in an eccentric motion.

Electromate provides a variety of zero backlash cycloidal gearboxes by Sumitomo Drive Technologies.
