Gearing: The Right Angle

New Case Studies Compare Spiroid & Worm Gearing Technologies

At Spiroid, we're often asked to provide a high-level overview of how our gearing technologies compare to other right angle solutions such as worms. While it's easy to make generalizations about one technology versus another, it is usually a fool's errand unless the comparison is made within the context of a specific application and follows a consistent design focus. Without such context or focus, universal statements comparing one gear technology to another are often misleading, if not downright false. 

Case in point: While Spiroid may be perceived as generally having a higher torque capacity than worm gears, any worm gear set can exceed a given Spiroid gear set if parameters such as size or reduction ratios aren't fixed. In other words, the trade-offs between torque, size, ratio and efficiency are simply too interrelated to ignore for a given comparison.

With all of this in mind, we set out to compare our Helicon right angle gear technology with that of a standard, ANSI/AGMA 6034-B92 worm design. To do this, we reviewed the two technologies through the lens of 3 separate focus areas, each with their own application requirements. The focus areas and respective application requirements were as follows:

Helicon vs Worm, Design Focus: "Maximize Torque"

maximize torque requirements


Helicon vs Worm, Design Focus: "Minimize Space Claim"

minimize space claim


Helicon vs Worm, Design Focus: "Maximize Efficiency"

maximize efficiency







Of course, since the three focus areas are largely interconnected, we also wanted to see what happens to the other two once a design is optimized. In other words, if our focus is to 'maximize torque,' what happens to the 'space claim' and 'efficiency' of that design, given the defined application requirements?
