Low backlash right angle worm gear reducer

Güdel
Low Backlash Positioning and Drive Units are based on the Duplex worm gear principle. The two worm and worm gear each have a different lead.
Through axial displacement of the worm, the backlash can be adjusted to a minimum. The flank contact will not be impaired and additional backlash adjustments are always possible without disassembling the gearbox.
The worms are of a special steel, which is hardened and ground. The worm gears are made from spheroidal graphite casting nitrated.
