Double-Stage RV Worm Gearbox for High-Ratio Applications

This double-stage RV series worm gearbox extends the reduction ratio up to 10000, providing precise speed reduction for applications requiring extreme torque multiplication and controlled motion.

Key Features

• Double-Stage Reduction: Achieves ratios up to 10000, ideal for applications needing very low output speeds.
• Self-Locking Capability: With ratios ≥60, it prevents reverse motion, enhancing safety and stability.
• Robust Materials: Alloy steel worm shaft (20CrMnTi) and patented KK alloy copper worm wheel ensure long-lasting performance.
• Versatile Configurations: Available as NMRV+NMRV or JWB+NMRV helical geared motor combinations.
• ISO 9001:2015 Certified: Consistent quality through certified production processes.

Technical Specifications

Models and Options

Available in various combined configurations: NMRV+NMRV (dual worm gearboxes), JWB+NMRV (with mechanical variator), and NMRV+VS (with variable speed drive). These combinations offer flexibility for different motor and speed control requirements.

Materials and Structure

The gearbox features a durable aluminum housing, a hardened alloy steel worm shaft for strength, and a KK alloy copper worm wheel for wear resistance. The double-stage design allows for high ratio multiplication in a compact footprint.

Applications

Suitable for stage equipment, door operators, and electric power systems that require very low speeds and high torque, such as revolving stages, heavy curtain drives, and precision positioning systems.

Customization

Custom ratios, input flanges, and output shafts are available. Consult our team to design a gearbox for your specific application.

FAQ

Q1: How does a double-stage gearbox achieve higher ratios?

By combining two worm gear sets in series, the ratio multiplies, enabling reductions up to 10000.

Q2: Can I use this for a stage revolve system?

Yes, the high ratio provides smooth, controlled rotation with high torque, ideal for revolving stages.

Q3: What is the maximum ratio available?

Double stage can achieve a ratio of 10000.

Q4: Is the gearbox easy to maintain?

Yes, it uses synthetic lubricant and designed for easy access to lubrication points.

Q5: Does it produce low noise?

Confirmed low noise operation, suitable for performance environments.

Q6: Are explosion-proof options available?

Please contact us for specific requirements, as we may need to assess the application.

Q7: What is the efficiency of double-stage gearboxes?

Efficiency is lower than single-stage due to additional friction, but it is optimized with the KK alloy copper wheel.

Q8: Can I get a combination with a motor?

Yes, we offer integrated geared motor solutions like NMRV+NMRV or JWB+NMRV.
