As a planetary gearbox manufacturer, we prioritize understanding the intricate components that define our products. Below is a detailed breakdown of the key components:
1. Sun Gear
The central gear, driven by the input shaft, transmits rotational motion to the planetary gears. Made from high-quality alloy steel with carburizing and quenching processes , the sun gear ensures durability and resistance to wear.
2. Planetary Gears
Multiple planetary gears (typically three or more) mesh simultaneously with the sun gear and the ring gear. These gears distribute the load evenly, enhancing torque capacity and reducing stress on individual teeth . Like the sun gear, they undergo precision grinding and hardening for performance .
3. Ring Gear (Annulus)
This outer gear with internal teeth encloses the planetary gears. Depending on the configuration, it can remain stationary or serve as the output. Surface-hardened alloy steel ensures longevity and smooth operation .
4. Planetary Carrier
The carrier holds the planetary gears in place and connects them to the output shaft. Its robust design, often using nodular cast iron, withstands high radial and axial loads while maintaining alignment .
5. Input and Output Shafts
Aligned coaxially, these shafts ensure compactness and efficient power transmission. The output shaft incorporates double radial seals for enhanced protection against contaminants .
6. Bearings and Seals
High-capacity roller bearings (e.g., fully loaded cylindrical rollers) support the gears and carrier, minimizing backlash and radial load capacity . Seals prevent lubrication leakage and environmental ingress, critical for longevity in harsh conditions .
7. Additional Design Features
Modular Construction: Standardized parts enable cost-effective mass production and rapid customization .
Optimized Lubrication: Advanced lubrication systems reduce friction and heat generation, critical for high-speed applications .
