A worm wheel wears in service, and the free play at the output grows with it. A dual lead worm lets you take that play back out with one small axial adjustment. Among the transmission components in a

A worm gear is a gear set that pairs a screw-shaped "worm" with a toothed "worm wheel" to carry motion between two shafts that don't intersect — almost always at a 90° angle. One turn of the

A worm gear drive is a right-angle transmission mechanism that pairs a screw-shaped shaft (the worm) with a toothed wheel (the worm wheel) to deliver high single-stage speed reduction, high torque mul

In short: A worm drive is a right-angle, high-reduction gear transmission built around a screw-shaped worm meshing with a toothed worm wheel. Because the mesh relies on sliding rather than rolling con
