OTT Worm and worm wheel: Driving rotation components for various applications requiring an high degree of accuracy, an high torque transmission and that without any back lash.

The OTT gear is a patented high-precision worm gear set that allows backlash to be set and adjusted. All OTT spiral gears are manufactured as special quality gears.

The worm gear set consists of the shaftworm and holow. Backlash can be changed by turning or moving the holow worm in relation to the shaftworm.

Higher than usual, the teeth have considerably more contact ratio than in standart worm gear pairs. This results in greater power transmission with great accuracy of the parts.

A minimum or maximum backlash can be set.
