A worm gear in a micro-tiller is a gear installed in the tiller's transmission system that works with a worm to transmit motion and power between two intersecting shafts. Its shape resembles a helical gear, but its teeth are specially designed to tightly wrap around the worm, achieving efficient and stable transmission.

The two shafts in a worm gear transmission are mutually perpendicular and intersecting. The worm can be seen as a helix with one or more teeth wound around a cylinder along a spiral line, while the worm gear resembles a helical gear, its teeth designed for tight meshing with the worm. During engagement, one rotation of the worm drives the worm gear through one or more teeth, thus achieving transmission. This transmission method gives worm gear drives a high speed reduction ratio, typically ranging from 3:1 to 100:1.
