A worm gear is a type of mechanical gear system that consists of a worm (a screw-like component) and a worm wheel (a gear that meshes with the worm). It is widely used in various industries for its ability to provide high reduction ratios, smooth and quiet operation, and self-locking capabilities. This makes it ideal for applications requiring precise motion control, such as in conveyor systems, elevators, and heavy machinery.
Our worm gear products are manufactured to meet high standards of quality and performance. Below are the detailed parameters for our standard worm gear models.
| Component | Material | Hardness (HRC) | Treatment |
|---|---|---|---|
| Worm | Case-hardened Steel | 58-62 | Precision Ground |
| Worm Wheel | Bronze Alloy | 80-100 HB | Centrifugally Cast |
| Model Number | Ratio Range | Output Torque (Nm) | Efficiency (%) | Max Input Speed (RPM) |
|---|---|---|---|---|
| WG-100 | 5:1 to 60:1 | 50-500 | 85-90 | 3000 |
| WG-200 | 10:1 to 100:1 | 200-2000 | 80-88 | 2500 |
| WG-300 | 15:1 to 120:1 | 500-5000 | 75-85 | 2000 |
| Model Number | Center Distance (mm) | Worm Diameter (mm) | Wheel Diameter (mm) | Weight (kg) |
|---|---|---|---|---|
| WG-100 | 50 | 20 | 100 | 2.5 |
| WG-200 | 80 | 30 | 150 | 5.0 |
| WG-300 | 120 | 40 | 200 | 10.0 |
Worm gears are used in a wide range of applications due to their unique properties. Common uses include:
What is the main advantage of a worm gear system?
The primary advantage is its ability to achieve high reduction ratios in a compact space, along with self-locking that prevents reverse motion, enhancing safety in applications like elevators.
How do I select the right worm gear for my application?
Consider factors such as required torque, speed ratio, operational environment, and space constraints. Our product tables provide detailed specs to help you choose the appropriate model based on these parameters.
Are worm gears efficient?
Worm gears typically have efficiencies ranging from 50% to 90%, depending on the ratio and design. Higher ratios may lower efficiency due to increased friction, but our models are optimized for better performance.
Can worm gears be used in high-speed applications?
Yes, but it depends on the model. Our WG-100 series supports input speeds up to 3000 RPM, making it suitable for many high-speed operations. Always check the max input speed specification for your chosen model.
What maintenance do worm gears require?
Regular lubrication is essential to reduce wear and heat generation. Inspect for wear and tear periodically, especially in high-load applications. Our gears are designed for minimal maintenance, but following manufacturer guidelines ensures longevity.
Are custom worm gear configurations available?
Yes, we offer custom solutions tailored to specific requirements, including unique ratios, materials, and sizes. Contact our engineering team with your needs for a personalized quote.
How does the self-locking feature work?
Self-locking occurs when the worm can drive the wheel, but the wheel cannot drive the worm due to the high friction angle. This prevents backdriving, making it ideal for applications where holding position is critical, such as in lifts or hoists.
What materials are best for worm gears?
The worm is typically made from hardened steel for strength, while the wheel is often bronze or a similar alloy to reduce friction and wear. This combination ensures durability and smooth operation.
Can worm gears be used in corrosive environments?
Yes, by selecting appropriate materials such as stainless steel or coated components, worm gears can be designed to resist corrosion. Specify your environment needs when ordering for suitable recommendations.
What is the typical lifespan of a worm gear? With proper maintenance and under normal operating conditions, our worm gears can last for many years, often exceeding 10,000 hours of operation. Factors like load, speed, and environment can affect lifespan, so regular checks are advised.
