Worm gearboxes are mechanical devices used to transmit power between non-intersecting shafts at right angles, offering high reduction ratios and compact design. They consist of a worm (screw) that meshes with a worm gear (wheel), providing smooth and quiet operation. These gearboxes are essential in various industries due to their ability to handle heavy loads and provide self-locking features, preventing backdriving in many applications.
Our worm gearboxes are engineered to meet rigorous industrial standards. Below is a detailed table of specifications for our standard models.
| Model | Ratio Range | Input Power (kW) | Output Torque (Nm) | Efficiency (%) | Weight (kg) | Mounting Type |
|---|---|---|---|---|---|---|
| WG-50 | 10:1 to 60:1 | 0.12 - 0.75 | 30 - 150 | 70 - 85 | 5.2 | Foot-mounted |
| WG-75 | 5:1 to 100:1 | 0.25 - 2.2 | 100 - 500 | 75 - 90 | 12.8 | Flange-mounted |
| WG-100 | 10:1 to 80:1 | 0.55 - 4.0 | 200 - 1000 | 80 - 92 | 25.5 | Shaft-mounted |
| WG-150 | 15:1 to 100:1 | 1.5 - 7.5 | 500 - 2000 | 85 - 94 | 48.0 | Foot and flange |
Additional parameters include operating temperature range: -20°C to 100°C, input speed up to 3000 RPM, and protection class IP55 for dust and water resistance. All models are lubricated with synthetic oil for extended life and come with optional accessories like fans for cooling or special seals for harsh environments.
What is the main advantage of using a worm gearbox?
The primary advantage is the high reduction ratio achievable in a compact size, along with the self-locking feature that prevents reverse motion, enhancing safety in applications like lifts or conveyors.
How efficient are worm gearboxes compared to other types?
Worm gearboxes typically have lower efficiency, ranging from 50% to 90%, due to sliding friction between the worm and gear. However, advancements in materials and lubrication have improved efficiency, making them suitable for many applications where space and ratio are critical.
Can worm gearboxes be used in high-speed applications?
Yes, but with limitations. Input speeds can go up to 3000 RPM, but higher speeds may require special designs with improved cooling and lubrication to avoid overheating and wear. It's essential to consult specifications for your specific model.
What maintenance is required for worm gearboxes?
Maintenance is minimal; primarily, regular lubrication checks and changes every 10,000 hours or as per operating conditions. Inspect for wear and tear, and ensure proper alignment to extend lifespan. Many models are sealed for life, reducing maintenance needs.
Are worm gearboxes reversible?
Generally, no, due to the self-locking effect where the worm can drive the gear, but the gear cannot drive the worm. This prevents backdriving, but some designs with high lead angles may allow reversibility; check product details for specific models.
What materials are used in worm gearboxes?
The worm is often made from hardened steel for strength and wear resistance, while the worm gear is typically bronze or a similar material to reduce friction and allow smooth operation. Housings are usually cast iron or aluminum for durability and heat dissipation.
How do I select the right worm gearbox for my application?
Consider factors like required reduction ratio, input power, output torque, mounting style, and environmental conditions (e.g., temperature, exposure to elements). Refer to our specification table and consult with our engineers for customized solutions based on load calculations and operational needs.
Can worm gearboxes be customized?
Yes, we offer customization options including specific ratios, special materials for corrosive environments, different mounting configurations, and integrated motors. Provide your application details for a tailored solution that meets exact requirements.
