The OTT worm gear is a patented high-precision
worm gear set where the backlash can be set and
adjusted. All OTT worm gears are manufactured to
the highest quality.
The worm gear is comprised of a pinion gear shaft
and ring gear. The backlash is adjusted by turning
or moving the pinion gear relative to the ring gear.
Due to the height of the tooth there is a significantly
larger contact ratio than with a normal worm gear.
This results in greater power transmission with great
The OTT-MATIC is another refinement of the OTT worm gear. The backlash can be adjusted
by moving the ring gear axially relative to the pinion
gear during rotation.
