A cylindrical gearbox is a mechanical device designed to transmit power and motion between parallel shafts using cylindrical gears. These gearboxes are renowned for their efficiency, durability, and versatility in various industrial applications. They are commonly used in manufacturing, automotive, mining, and energy sectors due to their ability to handle high loads and provide reliable performance under demanding conditions. The design typically involves helical or spur gears enclosed in a housing, which ensures protection and lubrication for prolonged operation.
Our cylindrical gearboxes are available in multiple series, each tailored for different operational requirements. Below is a detailed table outlining the standard parameters for our flagship models.
| Model Series | Gear Ratio Range | Input Power (kW) | Output Torque (Nm) | Efficiency (%) | Weight (kg) | Input Speed (RPM) |
|---|---|---|---|---|---|---|
| CGB-100 | 5:1 to 20:1 | 0.5 - 10 | 100 - 2000 | 95 - 98 | 15 - 50 | 1500 - 3000 |
| CGB-200 | 10:1 to 50:1 | 5 - 50 | 500 - 5000 | 94 - 97 | 50 - 150 | 1000 - 2500 |
| CGB-300 | 20:1 to 100:1 | 20 - 100 | 1000 - 10000 | 93 - 96 | 100 - 300 | 500 - 2000 |
| CGB-400 | 50:1 to 200:1 | 50 - 200 | 5000 - 20000 | 92 - 95 | 200 - 600 | 300 - 1500 |
Additional specifications include operating temperature range: -20°C to 120°C, protection class up to IP65, and lubrication options such as mineral oil or synthetic grease. All gearboxes undergo rigorous testing for noise levels (<75 dB) and vibration to ensure compliance with international standards like ISO 9001 and AGMA.
What is the typical lifespan of a cylindrical gearbox?
The lifespan depends on usage conditions, but with proper maintenance, our gearboxes can last 20,000 to 50,000 hours. Regular lubrication and avoiding overloads are key to maximizing durability.
How do I select the right gear ratio for my application?
Consider factors like input speed, desired output speed, and torque requirements. Our technical team can assist based on your specific machine parameters and operational goals.
Can cylindrical gearboxes be used in high-temperature environments?
Yes, our gearboxes are designed to operate in temperatures up to 120°C. For higher temperatures, special lubricants and materials can be customized upon request.
What maintenance is required for a cylindrical gearbox?
Routine maintenance includes checking oil levels every 500 hours, changing lubricant annually or after 2000 hours, and inspecting for leaks or unusual noise. Detailed manuals are provided with each unit.
Are these gearboxes reversible in operation?
Yes, most cylindrical gearboxes are bidirectional and can handle reversible loads, but it's essential to verify the model specifications to ensure compatibility with your application.
How does a cylindrical gearbox compare to other types like planetary or bevel gearboxes?
Cylindrical gearboxes are ideal for parallel shaft applications with high efficiency and simplicity, whereas planetary gearboxes offer higher torque in compact sizes, and bevel gearboxes are used for perpendicular shafts. Choice depends on spatial and performance needs.
What materials are used in the gear construction?
Gears are typically made from hardened steel, such as 20MnCr5 or 42CrMo4, to ensure strength and resistance to wear. Housing materials include cast iron for heavy-duty or aluminum for lightweight applications.
Is noise a concern with cylindrical gearboxes?
Our gearboxes are engineered for low noise operation (<75 dB) through precision grinding and helical gear designs, making them suitable for noise-sensitive environments like indoor facilities.
Can I get a customized gearbox for unique applications?
Absolutely. We offer custom designs for ratios, sizes, mounting options, and materials. Contact our engineering team with your requirements for a tailored solution.
What warranties do you provide?
We offer a standard warranty of 2 years from the date of purchase, covering defects in materials and workmanship. Extended warranties are available for critical applications.
