The Helical gearbox is a highly efficient power transmission device widely used in industrial applications due to its superior performance, durability, and smooth operation. Unlike spur gears, helical gears have teeth that are cut at an angle, allowing for gradual engagement and reduced noise and vibration. This makes them ideal for high-speed and high-torque applications in industries such as manufacturing, automotive, mining, and energy. Our helical gearboxes are engineered with precision to ensure optimal performance, reliability, and longevity, meeting the demanding needs of modern machinery.
Our helical gearboxes come in a range of sizes and specifications to suit diverse industrial requirements. Below is a detailed table outlining the key parameters for our standard models.
| Model | Ratio Range | Input Power (kW) | Output Torque (Nm) | Efficiency (%) | Weight (kg) | Mounting Position |
|---|---|---|---|---|---|---|
| HG-100 | 5:1 to 20:1 | 0.12 - 7.5 | 50 - 500 | 95-98 | 15 | Foot or Flange |
| HG-200 | 10:1 to 40:1 | 0.25 - 15 | 100 - 1000 | 96-98 | 30 | Foot or Flange |
| HG-300 | 15:1 to 60:1 | 0.37 - 22 | 200 - 2000 | 97-98 | 50 | Foot, Flange, or Shaft |
| HG-400 | 20:1 to 80:1 | 0.55 - 30 | 500 - 5000 | 97-98 | 80 | Foot, Flange, or Shaft |
| HG-500 | 25:1 to 100:1 | 0.75 - 45 | 1000 - 10000 | 98 | 120 | Foot, Flange, or Shaft |
Helical gearboxes are versatile and used in numerous industries for applications such as conveyor systems, mixers, extruders, cranes, elevators, pumps, and wind turbines. Their ability to handle high loads with efficiency makes them a preferred choice in scenarios requiring reliable power transmission.
What is a helical gearbox and how does it differ from other gearboxes?
A helical gearbox uses gears with teeth cut at an angle to the axis of rotation, allowing for smooth and quiet operation with higher efficiency compared to spur gearboxes. The angled teeth enable gradual engagement, reducing noise and vibration, and distributing load more evenly across the gear face.
What are the main advantages of using a helical gearbox?
The main advantages include high efficiency (up to 98%), reduced noise and vibration, ability to handle high loads and speeds, compact design, and longer lifespan due to better load distribution and less wear.
How do I select the right helical gearbox for my application?
Consider factors such as required torque, speed ratio, input power, operating environment, mounting position, and space constraints. Refer to the product specifications table and consult with our engineering team for custom solutions if needed.
What maintenance is required for a helical gearbox?
Regular maintenance includes checking oil levels and quality, inspecting for leaks, and ensuring proper alignment. Lubrication should be replaced as per the manufacturer's recommendations, typically every 10,000 to 20,000 hours of operation, depending on the model and conditions.
Can helical gearboxes be used in harsh environments?
Yes, our helical gearboxes are designed with robust materials and IP65 protection, making them suitable for harsh conditions including dust, moisture, and extreme temperatures. Always verify the specific model's ratings for your environment.
Are custom ratios and configurations available?
Absolutely, we offer customizable gear ratios, shaft sizes, mounting options, and materials to meet unique application requirements. Contact our sales team with your specifications for a tailored solution.
How does the efficiency of a helical gearbox compare to other types?
Helical gearboxes are generally more efficient than worm or bevel gearboxes, with efficiencies often exceeding 95%, compared to 50-90% for worm gearboxes. This results in lower energy consumption and operating costs.
What is the typical lifespan of a helical gearbox?
With proper maintenance, a helical gearbox can last over 20 years in industrial applications. Factors such as load, operating conditions, and maintenance practices influence the actual lifespan.
Do helical gearboxes require special installation procedures?
Installation should follow standard practices, including ensuring a solid foundation, proper alignment with connected equipment, and correct lubrication. Refer to the user manual for detailed instructions specific to the model.
Can I replace an existing gearbox with a helical gearbox?
In many cases, yes, but it requires matching the mounting dimensions, shaft sizes, and performance parameters. Our team can assist with retrofitting solutions to ensure compatibility and improved performance.
