A worm gear set is a set of gears consisting of a worm (pinion) and a worm-wheel (worm gear), often used when a high ratio is required and space is limited.
The pinion meshes with the teeth of the worm gear at 90 degrees, and motion is transmitted to the worm wheel when the worm pinion is rotated. Since the pinion is captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm set can be altered by changing the number of teeth on the wheel or changing the number of starts on the pinion.
These are used in a variety of industries including aerospace and military instrumentation, medical, dental, oil and gas exploration, robotics, optical and industrial controls.
We offer a large variety of options, and custom options can be made available on request.
