A helical bevel gearbox is a specialized type of gear reducer that combines helical and bevel gear technologies to deliver efficient power transmission in a compact design. It is widely used in industrial applications where high torque, smooth operation, and right-angle power transfer are required. This gearbox is known for its durability, low noise levels, and ability to handle heavy loads, making it ideal for sectors such as manufacturing, automotive, mining, and material handling.
Our helical bevel gearbox is engineered to meet rigorous industrial standards. Below is a detailed table of parameters for different models.
| Model | Ratio Range | Input Power (kW) | Output Torque (Nm) | Efficiency (%) | Weight (kg) |
|---|---|---|---|---|---|
| HBG-100 | 5:1 to 20:1 | 0.12 - 22 | 50 - 500 | 96 | 15 |
| HBG-200 | 5:1 to 25:1 | 0.25 - 45 | 100 - 1000 | 97 | 30 |
| HBG-300 | 5:1 to 30:1 | 0.37 - 90 | 200 - 2000 | 98 | 50 |
| HBG-400 | 5:1 to 40:1 | 0.55 - 160 | 500 - 5000 | 98 | 80 |
Additional specifications include input speeds up to 3000 RPM, operating temperatures from -20°C to 120°C, and protection ratings up to IP65 for dust and water resistance. All gearboxes are lubricated with high-performance oil and require minimal maintenance under normal conditions.
Compared to worm gearboxes or straight bevel gearboxes, the helical bevel gearbox offers superior efficiency and smoother operation. The helical teeth engage gradually, reducing noise and wear, while the bevel design allows for right-angle power transmission without sacrificing space. This combination results in higher load capacity and longer service life, making it a cost-effective solution for many industries.
What is a helical bevel gearbox used for?
A helical bevel gearbox is primarily used for applications requiring right-angle power transmission with high efficiency and torque. It is common in industrial machinery, automotive systems, and heavy equipment where space constraints and performance are critical.
How does a helical bevel gearbox differ from a standard bevel gearbox?
A helical bevel gearbox incorporates helical teeth on the bevel gears, which engage more smoothly and quietly compared to the straight teeth of a standard bevel gearbox. This results in higher efficiency, reduced vibration, and improved durability under heavy loads.
What maintenance is required for a helical bevel gearbox?
Regular maintenance includes checking oil levels every 3-6 months, replacing lubricant annually or after 10,000 hours of operation, and inspecting for wear or damage. Proper alignment and clean operating conditions can extend the gearbox's lifespan significantly.
Can helical bevel gearboxes be customized for specific applications?
Yes, these gearboxes can be customized in terms of gear ratios, mounting configurations, input/output shaft sizes, and materials to suit specific operational requirements, such as high-temperature environments or corrosive conditions.
What are the typical efficiency ratings for helical bevel gearboxes?
Efficiency typically ranges from 95% to 98%, depending on the ratio and load conditions. This high efficiency is due to the optimized gear design, which minimizes energy loss through heat and friction.
How do I select the right helical bevel gearbox for my application?
Consider factors such as required torque, input speed, ratio, operating environment, and space constraints. Consulting with an engineer or referring to technical charts based on load calculations can help in selecting the appropriate model.
Are helical bevel gearboxes noisy?
No, they are designed for low noise operation. The helical teeth engage gradually, which reduces vibration and sound levels compared to other gear types, making them suitable for noise-sensitive environments.
What materials are used in manufacturing helical bevel gearboxes?
Common materials include hardened steel for gears, cast iron or aluminum for housings, and high-quality bearings. These materials ensure strength, corrosion resistance, and long-term reliability in various industrial settings.
Can these gearboxes handle reverse operation?
Yes, helical bevel gearboxes are capable of bidirectional operation, making them versatile for applications requiring forward and reverse motion, such as in conveyors or lifting equipment.
What is the average lifespan of a helical bevel gearbox?
With proper maintenance and under normal operating conditions, these gearboxes can last 20,000 to 50,000 hours or more. Factors like load, environment, and maintenance frequency influence the actual lifespan.
