Long Shaft Gear

The design of long shaft gear prioritises not only tooth strength and precision but also structural functionality as shaft components. Utilising powder metallurgy techniques, we achieve true ‘gear-shaft integration’ by forming high-precision journal shafts, locating shoulders, keyways, or specialised connection structures directly onto the gear body in a single operation. This design eliminates potential issues inherent in traditional ‘gear-plus-shaft’ assemblies, such as misalignment and micro-motion wear, significantly enhancing the overall rigidity and reliability of the transmission system.

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 Controllability

The 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.
