Cycloidal (planocentric) Gearboxes employ eccentric motion to achieve its speed reduction. It uses noncircular 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 Harmonic Drive® products, which employ 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.
Cycloidal Speed Reducer Features (Circulute 3000):
- 35 basic sizes, available as single, double and triple reduction units
- Input power range from 1/8 HP (.1 kW) to 60 HP (45 kW)
- Ratio range from 11:1 to 357,911:1
- Output torque range from 377 in. lbs. (42 Nm) to 65,000 in. lbs. (7,340 Nm)
