Spiroid® & Helicon® Gearing

The Spiroid brand includes two similar gearing solutions, Spiroid Gears and Helicon Gears. These gear sets are comprised of a pinion and a face-gear operating in non-intersecting and non-parallel axes.

Spiroid and Helicon gear systems are advantageous in that they broaden gearing design opportunities restricted by the physical limitations of conventional gearing. In essence, they represent another powerful design option for engineers looking to transmit higher torques, within smaller spaces, at 90-degree gearbox angles. Spiroid and Helicon: maximum power density in a right angle gearbox solution.
