Double Reduction Worm Gearbox Units are constructed using two single reduction worm gear units. The primary worm gear unit is specially designed to mount integrally on a standard single worm gear unit which forms the secondary stage. The complete gear unit becomes compact and rigid in arrangement for slow moving machinery. A wide range of ratio from 100:1 to 6000:1 is available. These gear units are particularly suitable for high torque slow-speed drives. This provide Right angle drive ref to input power direction.
We provide double reduction in NMRV AND NU MODELS.
NMRV DOUBLE REDUCTION design compact and light weight in aluminium and casting body combination, which can mount with flange mount motor.
SNU / FHU DOUBLE REDUCTION design rigid and heavy duty in cast iron body only, which can mount by foot mount motor.
Applications
- Conveyors
- Agitator
- Feeder Table
- Bucket Elevator
- Mixer
- Bulk Materials Handling
- Crane Carrier
FAQs for Double Reduction Worm Gearbox
What is a Double Reduction Worm Gearbox?
A Double Reduction Worm Gearbox combines two single-stage worm gear units to achieve a much higher speed reduction in a compact arrangement. It is mainly used in slow-speed machinery that requires high output torque.
What reduction ratios are available in a Double Reduction Worm Gearbox?
Speedo Gear offers Double Reduction Worm Gearboxes with reduction ratios ranging from 100:1 to 6000:1, making them suitable for applications requiring extremely low output speed.
What are the main applications of a Double Reduction Worm Gearbox?
Double Reduction Worm Gearboxes are commonly used in conveyors, agitators, feeder tables, bucket elevators, mixers, bulk-material handling systems and crane carriers.
What are the benefits of using a Double Reduction Worm Gearbox?
The main benefits include a high reduction ratio, high output torque, compact construction, right-angle power transmission and reliable operation in slow-moving industrial machinery.
Is a Double Reduction Worm Gearbox suitable for high-torque applications?
Yes. It is specifically designed for high-torque and low-speed applications where a standard single-reduction gearbox may not provide the required output speed or reduction ratio.
What is the difference between single and Double Reduction Worm Gearboxes?
A single-reduction gearbox uses one worm gear stage, while a Double Reduction Worm Gearbox uses two connected reduction stages. The double-reduction design provides a much higher gear ratio and slower output speed.
Which Double Reduction Worm Gearbox models are available?
Speedo Gear provides Double Reduction Worm Gearboxes in NMRV and NU models. NMRV models use a compact aluminium and cast-body combination, while SNU/FHU heavy-duty models use cast-iron construction.
What is an NMRV Double Reduction Worm Gearbox?
An NMRV Double Reduction Worm Gearbox is a compact and lightweight model manufactured using an aluminium and cast-body combination. It can be connected to a flange-mounted motor.
