A planetary gearbox, also known as an epicyclic gearbox, is a high-precision gear system used in various industrial applications for torque multiplication, speed reduction, and compact power transmission. It consists of a central sun gear, planet gears that rotate around the sun gear, and a ring gear that encloses the system. This design offers high efficiency, durability, and versatility, making it ideal for machinery, automotive systems, robotics, and renewable energy equipment.
Our planetary gearboxes are engineered with precision to meet demanding industrial standards. Below are the detailed specifications presented in lists and tables for clarity.

| PG-400 | 20:1 to 300:1 | 5000 - 20000 | 10000 - 40000 | 0 - 2500 | < 5 | 100 - 500 |
Planetary gearboxes are utilized across multiple industries due to their robustness and efficiency. Common applications include:
What is a planetary gearbox used for?
A planetary gearbox is primarily used for torque multiplication, speed reduction, and precise power transmission in compact spaces. It is common in applications like robotics, automotive systems, and industrial machinery where high efficiency and durability are required.
How does a planetary gearbox work?
It operates with a central sun gear that drives multiple planet gears, which are mounted on a carrier and mesh with an outer ring gear. This arrangement allows for balanced load distribution, high torque output, and smooth operation with minimal backlash.
What are the advantages of a planetary gearbox over other types?
Key advantages include high power density (more torque in a smaller size), greater efficiency due to multiple gear contact points, lower noise and vibration, and excellent durability with even load sharing among planets.
How do I select the right planetary gearbox for my application?
Consider factors such as required torque, speed ratio, operational environment (temperature, humidity), mounting configuration, and backlash tolerance. Our parameter tables and expert support can help guide selection based on your specific needs.
What maintenance does a planetary gearbox require?
Most modern planetary gearboxes are designed for minimal maintenance, often featuring sealed lubrication systems. Regular inspections for wear, proper lubrication checks, and ensuring alignment can extend lifespan. Specific intervals depend on usage intensity and environmental conditions.
Can planetary gearboxes be customized?
Yes, we offer customization options including specific ratios, materials, coatings, mounting styles, and integration with other components like motors or encoders to meet unique application requirements.
What is the typical lifespan of a planetary gearbox?
With proper installation and maintenance, planetary gearboxes can last over 20,000 hours of operation. Lifespan varies based on load conditions, operating speed, and environmental factors, but high-quality units like ours are built for long-term reliability.
Are planetary gearboxes suitable for high-speed applications?
Absolutely. Many models support input speeds up to 4000 RPM or higher, making them ideal for high-speed machinery, turbines, and precision equipment where rapid motion is necessary without sacrificing torque or efficiency.
How do I ensure proper installation of a planetary gearbox?
Follow manufacturer guidelines for alignment, mounting, and lubrication. Use appropriate tools to avoid over-tightening, ensure shafts are properly coupled, and verify that operational parameters (e.g., load and speed) are within specified limits to prevent damage.
What should I do if my planetary gearbox fails or shows signs of wear?
Immediately stop operation and inspect for common issues like noise, overheating, or leakage. Contact our support team for diagnostics; we offer repair services and replacements, and early intervention can prevent further damage to connected systems.
