Planetary Carrier

The planetary carrier is a critical structural part in planetary gear mechanisms, supporting multiple planetary gears while maintaining alignment under load. Guangming Group produces these carriers using powder metallurgy, which enables the integration of complex features such as mounting holes, lightening pockets, and flange geometries in a single pressing. The result is a component with excellent dimensional stability, high strength-to-weight ratio, and consistent quality.Our powder metallurgy planetary carriers feature precision-machined key surfaces and are widely used in automotive parts, industrial gearbox components, and gear assemblies for household appliances.

Product Feature And Application

Powder metallurgy (PM) technology demonstrates significant competitive advantages in the field of gear manufacturing, particularly in mass production, complex shapes, material savings, and cost control. With the continuous development of new materials and processes, and the application of intelligent manufacturing technologies, PM gears will replace traditionally machined gears in more high-end applications, becoming an important component of modern manufacturing.

Process Application Features:

（1）Integrated Molding: Bearing mounting holes, planetary shaft holes, connecting flanges, and other features are formed in a single molding process.

（2）Multi-Stage Pressing:3-5 pressing stages are used to control density in different thickness regions.

（3）Reinforcement Rib Design: Reinforcement rib structures are directly formed during the pressing process to improve rigidity.

（4）Weight Reduction Hole Forming: Weight reduction holes are directly pressed, avoiding subsequent drilling.

Process Advantages:

（1）70% Reduction in Part Count: Multiple parts are integrated into a single PM (Powder Metallurgy) part.

（2）25-30% Weight Reduction: Lightweight design is achieved through topology optimization and weight reduction hole design.

（3）15-20% Increase in Rigidity and Strength: Optimized material distribution improves structural performance.
