Hand Crank Bevel Gear 17 Teeth

We select high-purity reduced iron powder or atomized alloy steel powder as the base material, precisely blending alloy elements such as copper, nickel, and molybdenum according to the gear's load requirements. Under hundreds of megapascals of pressure, the powder is compacted into dense green compacts within high-precision dies, with the tooth profile essentially taking shape at this stage.

The subsequent high-temperature sintering process achieves more than simple bonding—it creates true metallurgical bonding through atomic diffusion, forming a microstructure with both high strength and toughness. For gears requiring enhanced wear resistance, we can apply heat treatment processes to maintain both wear resistance and high strength.

Product Feature And Application

Powder metallurgy pressing has become the preferred manufacturing technology for modern gears, particularly for components like lift table transmission gears that demand high-volume production, exceptional consistency, complex geometries, and outstanding cost-effectiveness. Its application and advantages in gear manufacturing are reflected in the following aspects:

1. Near-net-shape forming with exceptional material utilization

Powder metallurgy directly compresses loose powder into gear blanks, achieving stable material utilization rates exceeding 95%. This significantly reduces raw material costs and aligns with green manufacturing principles.

2. Integrated Forming of Complex Structures

Utilizing molds, powder metallurgy enables the complete pressing of all features—including the tooth profile itself—in a single operation.

3. Exceptional Dimensional Accuracy and Batch Consistency

Mold-based forming ensures tens of thousands or even millions of gears produced from the same mold exhibit outstanding dimensional consistency and interchangeability. This greatly enhances assembly efficiency and overall machine quality stability for production lines requiring large-scale manufacturing and strict gear pairing, such as lift tables.

4. Superior Material Properties and ControllabilityThe sintered structure is uniform and non-directional. By adjusting formulations and sintering/heat treatment processes, gear properties can be flexibly customized—such as high wear resistance, high fatigue strength, and excellent impact toughness.
