Worm gearbox


closed design

Low-noise gear drive

Worm gear units are used when large ratios are requierd. The worm gear consists of a gear wheel and a shaft of the worm. The worm gearbox is self-locking due the low inclination angle. For this reason, worm gear units are highly suitable for applications in which the gear unit should not run backwards even under load.

The transmission ratio results from the quotient of the number of teeth on the worm wheel and divided by the number of gears of the worm.
