Triple Worm Speed Reducers
Delroyd DDVM series triple-reduction worm gear speed reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Output torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in lbs for the DDVM-200. Mechanical HP input requirements are from 0.09 HP for the 175,000:1 7 in CD reducer to 6.25 HP for the 5000:1 20” CD unit. These reducers are available in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water equipment drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other available configurations also make Delroyd triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where large torques/slow speeds are needed.
These reducers are also available with a helical primary reduction stage and are termed the HDVM series
