Valve Dual Spur Gear

The valve dual spur gear serves as a critical component for achieving multi-stage reduction or power-split transmission. Its manufacturing challenges lie in the relative positional accuracy of the two gear stages and the overall dynamic balance. Our powder metallurgy process demonstrates its advantages here. The valve dual spur gear is formed as a single integral component through a single pressing operation, achieving coaxiality between the two gear stages within ±0.02mm and end-face parallelism less than 0.01mm. Finite element analysis optimises the connecting rib structure between the gear stages, ensuring sufficient torsional rigidity while achieving weight reduction.

Core Advantages of Powder Metallurgy Gears in Actuator Valve Transmission Systems

（1）Near-net-shape forming and cost-effectiveness: Complex geometries (such as double-helical gears and gears with bosses) are formed in a single operation, achieving material utilisation exceeding 95%. Compared to forging followed by machining, this reduces costs by 30–50%, making it particularly suitable for high-volume production.

（2）Superior Material Properties and Consistency: Powder metallurgy materials exhibit uniform microstructure, free from segregation, with excellent isotropy. Through sinter hardening or subsequent heat treatment, an ideal combination of strength, hardness, and toughness is achieved, with minimal batch-to-batch variation in performance.

（3）High Design Integration: Features such as bushings, flanges, special-shaped holes, and oil grooves can be directly integrated onto the gear itself. This simplifies assembly, reduces component count, and enhances overall system rigidity and reliability.Choosing our powder metallurgy solutions means selecting a high-performance approach that deeply integrates materials science, precision manufacturing and innovative design. Not only does it enable your actuator products to achieve unprecedented precision and reliability, but it also creates greater commercial value through streamlined supply chains and enhanced production efficiency. We look forward to collaborating with you to push the boundaries of precision transmission technology.
