A Helicon or Spiroid gear set is either left or right-handed. The “Hand” is determined by the direction of the pinion thread (clockwise/counterclockwise). The two images below illustrate relative pinion positions for both left and right-hand systems, enabling design flexibility.

Proper alignment is critical for maximized gear set performance. In preparation for assembly of the gear set, the housing should be inspected using the following guidelines.

The center distance, “A” dimension shown below, should be within ±0.001 inch per inch. (For example, a 3.000 inch center distance would have a tolerance of ±0.003 inch.)

The alignment of the bores, which will locate the pinion and gear, should also be checked. The shaft angle (usually 90˚) should be within ±5’. Deviation from the nominal shaft angle will cause a contact pattern shift between the assembled pinion and gear. Heavy localized contact toward the inner or outer band of gear teeth is not desirable.

For over 40 years, Spiroid products have played an important role in our nation’s land, sea, air, and space defense systems. Whether actuating tank turrets, missile fins, afterburner flaps or naval weapons handling systems, Spiroid gearing has always been reliably up to the task. While defense applications have wide and varying requirements, Spiroid is often sought and preferred for its high shock strength, extreme accuracy and brute strength – all in a small package.

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. By definition, the pinion has fewer teeth and is typically the driving member. This category of gearing is often referred to as “skew axis”.

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.
