Fine-pitch worm gearing is segregated from coarse-pitch worm gearing for the following reasons:ġ) Fine-pitch worms and wormgears are used largely to transmit motion rather than power. Worm gearing may be divided into two general classes, fine-pitch worm gearing, and coarse-pitch worm gearing. This article will provide a review of common worm gearing types, classes, standards, materials, and methods of fabrication.



Worm gearing is found in many different applications for mechanical power transmission, from the tuning pegs of stringed musical instruments to elevators, conveyor systems, and vehicle differential drive systems.
