A Planetary Gearbox, also known as an epicyclic gearbox, is a compact and efficient gear system that consists of a central sun gear, planet gears, a ring gear, and a carrier. This design allows for high torque transmission, smooth operation, and excellent power density, making it ideal for various industrial applications such as robotics, automotive systems, and heavy machinery.
Our planetary gearboxes are engineered to meet rigorous industrial standards. Below are the detailed specifications for our standard models:
| Model | Gear Ratio Range | Rated Torque (Nm) | Max Input Speed (RPM) | Efficiency (%) | Weight (kg) | Backlash (arcmin) |
|---|---|---|---|---|---|---|
| PG-100 | 3:1 to 10:1 | 100 - 500 | 5000 | 95-97 | 2.5 | <5 |
| PG-200 | 5:1 to 25:1 | 200 - 1000 | 4500 | 94-96 | 4.0 | <6 |
| PG-300 | 10:1 to 50:1 | 500 - 2000 | 4000 | 93-95 | 7.5 | <7 |
| PG-400 | 20:1 to 100:1 | 1000 - 5000 | 3500 | 92-94 | 12.0 | <8 |
Planetary gearboxes are versatile and used in numerous industries due to their reliability and performance. Common applications include:
What is the main advantage of a planetary gearbox over other gear types?
The primary advantage is its compact size combined with high torque capacity and efficiency. The planetary arrangement allows for load distribution across multiple gears, reducing wear and enabling smoother operation.
How do I select the right planetary gearbox for my application?
Consider factors such as required torque, speed, ratio, space constraints, and environmental conditions. Our technical team can assist in choosing the appropriate model based on your specific needs.
What maintenance is required for a planetary gearbox?
Regular lubrication checks and periodic inspections for wear are essential. Most models are designed for minimal maintenance, but following the manufacturer's guidelines ensures longevity.
Can planetary gearboxes be used in high-temperature environments?
Yes, with proper material selection and lubrication. Our gearboxes can be customized with heat-resistant materials and synthetic lubricants to operate in temperatures up to 120°C.
What is backlash, and why is it important?
Backlash is the slight movement between gears when direction changes. Low backlash is crucial for precision applications like robotics to ensure accurate positioning and reduce error.
Are custom ratios available for planetary gearboxes?
Absolutely. We offer customizable gear ratios to meet specific application requirements, ensuring optimal performance and efficiency.
How does a planetary gearbox handle high loads?
The load is distributed among multiple planet gears, which reduces stress on individual components and allows for higher load capacity compared to standard gear systems.
What materials are used in your planetary gearboxes?
We use high-quality hardened steel for gears, alloy housings, and precision bearings to ensure durability, corrosion resistance, and long service life.
Can I integrate a planetary gearbox with my existing motor?
Yes, our gearboxes are designed with standard mounting interfaces and can be easily paired with various motors, including servo and stepper motors.
What is the typical lifespan of a planetary gearbox?
With proper maintenance, our planetary gearboxes can last over 20,000 hours of operation, depending on the application and operating conditions.
