Advantages of worm Gears

 The efficiency of worm gear depends on the lead angle, sliding speed, and lubricant, surface quality and installation conditions. They offer smoothest, quietest form of gearing. They provide high-ratio speed reduction in minimal spaces.

 Worm gears work under difficult conditions, presenting unique lubrication demands. The types of oils most commonly used to

lubricate worm gears are compounded mineral oils, EP mineral gear oils and synthetics.
