 Ratios
5000:1 to 175,000:1
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 in. (larger sizes are
available on request). Output torque ranges from 33,000 in. lbs. for
the 7-in. CD DDVM-70 to 582,900 in. lbs. for the DDVM-200.
Mechanical HP input requirements are from 0.09 for the 175,000:1
7-in. CD reducer to 6.246 for the 5000:1 20-in. CD unit.
These reducers are available in any four
configurations: horizontal, vertical, shafted and shaft-mounted.
They are ideal for water/wastewater equipment
drive applications such as thickeners and clarifiers which require a
vertical downshaft. Other available configurations also make
Delroyd®
triple reduction reducers perfect for use on mixers, elevators,
solar panels, astronomical telescopes, indexing tables, hoists,
conveyers 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.
- HP from 0.09 to 6.25
- Output torque to 583,000 in. lbs.
- Output rpm as low as 0.01 with a 1750 rpm input
- Ideal for ultra-slow speed, high torque applications
