RV Series Worm Gearbox for Stage Equipment

Our RV series worm gearbox is engineered for demanding applications like stage equipment, door operators, and electric power systems. With a self-locking ratio of ≥60, it ensures secure positioning and safety in intermittent, variable-load operations.

Key Features

• Self-Locking Ratio ≥60: Prevents reverse driving, enhancing safety in lifting and positioning applications.
• Superior Alloy Steel Worm Shaft (20CrMnTi): High hardness through special heat treatment, ensuring long service life.
• Patented KK Alloy Copper Worm Wheel: Excellent wearability reduces downtime and maintenance.
• Wide Ratio Range: Single stage up to 100, double stage up to 10000, offering flexibility for various speed reduction needs.
• Quiet and Smooth Operation: Tested for low noise, meeting strict stage performance requirements.
• ISO 9001:2015 Certified: Manufactured under a quality management system for consistent reliability.

Technical Specifications

Models and Options

RV series is available in single-stage and double-stage configurations to achieve ratios up to 10000. For stage applications, models with self-locking ratios (i≥60) are recommended. Standard models include NMRV and NRV variants, and integrated geared motor options are available.

Materials and Structure

The worm shaft is made of superior alloy steel (20CrMnTi) with special heat treatment for high hardness. The worm wheel uses patented premium KK alloy copper, known for excellent wearability. The housing is made of aluminum alloy (Aluminum Parts), providing lightweight and corrosion-resistant properties. This combination ensures robust performance and durability.

Applications

Designed for stage equipment (circular light lifting, prism light lifting), door operators, and electric power systems. The gearbox supports intermittent operation, frequent start-stop, variable loads, and forward/reverse switching. It is also suitable for stage automation systems, electric hoists, and revolving stage drives.

Customization

We offer customization to meet specific requirements, including mounting configurations, input/output shaft types, and integrated motor options. Contact our engineering team for application-specific solutions.

FAQ

Q1: What is the self-locking function?

At ratios ≥60, the worm gearbox prevents reverse driving, meaning the output shaft cannot be turned by external force. This is critical for safety in lifting applications.

Q2: Can I get a high-ratio version for my stage hoist?

Yes, double-stage configurations allow ratios up to 10000, suitable for slow, precise movements.

Q3: What maintenance is required?

Use synthetic worm gear special lubricating oil to maintain transmission efficiency and extend service life. Regular oil checks are recommended.

Q4: Is the gearbox suitable for quiet stage environments?

Yes, it operates with ultra-low noise, meeting the quiet requirements of performances.

Q5: Do you have CE certification?

Our products comply with ISO, CE, and CCC standards, ensuring international market acceptance.

Q6: How does the KK alloy copper improve performance?

It provides excellent wearability, reducing wear and increasing the gearbox's operational life.

Q7: Can the gearbox handle frequent start-stop cycles?

Yes, it is designed for intermittent operation with frequent start-stop and variable loads.

Q8: What is the delivery time?

Please inquire for specific lead times based on order quantity and customization.
