The planetary gear is the core transmission element in planetary gear systems. It operates by rotating around a central sun gear, enabling high gear reduction ratios and efficient power transmission in compact spaces. Within the gearbox, it bears critical torque transmission and load distribution functions. The tooth strength, internal structural uniformity, and fatigue life directly determine the overall reliability and durability of the Transmission System. As a forged blank for further machining process, this planetary gear forged blank provides a stable and high-performance base for subsequent gear cutting processes such as hobbing, shaping, grinding.
The production follows a rigorous manufacturing and inspection process, including:
1.Incoming Material Inspection
2.Blank Cutting
3. Ring Rolling
4.Post- Forging Inspection
5.Normalizing
6.Rough Turning
7.Quenching & Tempering
Material: Alloy Steel (e.g., 42CrMo4, 34CrNiMo6, 18CrNiMo7-6)
Applications:
Our planetary gear Forged Blanks , manufactured through ring rolling forging are mainly supplied to leading wind turbine gearbox manufacturers, but also widely applied across other heavy-duty power transmission fields:
- Wind Power – Planetary gear stages inside main gearboxes of wind turbines, ensuring high torque transmission and system stability.
- Construction Machinery – Travel and swing reducers in excavators, loaders, and cranes, exposed to frequent impact and dynamic loads.
- Mining Equipment – Planetary gears in cutting head drives and reduction systems of Mining Machinery, requiring high wear and fatigue resistance.
- Industrial Gearboxes – Core Transmission Components in medium and large planetary reducers used in metallurgy, cement, and marine applications.
