Worm Gear Overview

At Superior Gearbox Company, we’ve manufactured high-quality gear drives for power transmission systems for over 45 years. One of our core product offerings is low input speed worm gear reducers.

To achieve greater torque from a transmission requires a reduction of speed.  Speed reduction is the primary function of the Variodrive worm gear speed reducer series.  A worm gear speed reducer consists of a worm pinion input and output worm gear oriented for perpendicular output, which produces a higher torque value in relation to the applied reduction ratio.  The small diameter of the output gear allows the Variodrive to be used in applications where space is limited. In addition to decreased space and greater simplicity, our Variodrive series was designed to be directly interchangeable with most industry standard NRV & NMRV worm gear reducer solutions.

How Does a Worm Gear Reducer Work?

A worm pinion is a screw used to input power to the assembly. When coupled with a standard spur gear fitted with slightly angled teeth in a perpendicular alignment, known as a worm gear or worm wheel, the pairing becomes a worm gear reducer. As power from an engine or motor turns the worm pinion, its spirals push the teeth on the worm wheel, causing it to turn in accordance with the designed reduction ratio as it applies load to its drive shaft.

Higher reduction ratios may be achieved by increasing the circumference of the worm gear, or by increasing the number of threads on the worm pinion. Accomplishing the same reduction using conventional gear sets requires multiple reductions, which take up more space. Increasing the number of parts raising costs and adding to the risk of component failure.

Worm gear speed reducers provide efficient, space-saving solutions for speed reduction and increased torque when compared with bulkier, higher-maintenance conventional gearsets. Superior Gearbox’s Variodrive series is designed to overcome common speed reduction challenges with greater dependability and better performance, and extends to meet the needs of markets that require very high sanitary and hygienic design solutions with our Cleandrive Series.
