Product Description
Core Advantage
1. Material and process characteristics
- Diverse materials: Using iron, copper, stainless steel or mixed alloy powder (such as Fe-Cu-C, Fe-Ni-Mo, etc.), the material ratio can be customized to optimize strength, wear resistance and corrosion resistance.
- Near-Net Shape: Direct pressing, reduce the amount of machining, reduce material waste and production costs.
- High density and uniformity: Increase gear density (up to 7.4 g/cm³ or more) through cold isostatic pressing, warm pressing or repressing and refiring processes to ensure stable mechanical properties.
2. Performance advantage
- High strength and wear resistance: By heat treatment (such as carburizing, quenching) or surface treatment (steam oxidation, phosphating) to enhance the hardness of the tooth surface (HRC 50-60), extend the service life.
- Low noise operation: Precision mold molding ensures profile accuracy (DIN 6-8), smooth meshing, reducing vibration and noise.
- Lightweight design: Porous structure can contain oil (oil content 10-20%) to achieve self-lubrication and reduce maintenance requirements.
3. Complex structure adaptability
Can form bevel gears, bevel gears, internal gears and gears with convex/shaped holes in one piece, avoiding the limitations of traditional cutting.
Typical Application Scenarios
- Automotive industry: transmission gear, starter gear, oil pump gear, differential pinion.
- Industrial Equipment: reducer gear, motor transmission parts, automatic mechanical drive unit.
- Consumer Electronics: Home appliance motor gear, power tool transmission system, office equipment precision gear set.
- New energy field: electric bicycle central motor gear, UAV power transmission components.
