Double Helical Gear

Our double helical gears are produced using advanced powder metallurgy techniques that allow for the formation of precise helical tooth profiles with consistent lead angles. The angled teeth design ensures multiple teeth are in contact at any time, leading to higher load capacity and smoother torque transfer compared to spur gears. Guangzhou Guangming Metal Products Co.,Ltd's double helical gear are made from high-quality alloy powders and can be case-hardened for increased surface durability. They are ideal for applications requiring high-speed operation, low noise levels, and efficient power transmission, including gear pumps, conveyor drives, and machine tool spindles.

Product Feature And Application

Key advantages of powder metallurgy for iron-based double helical gears:

1. Near-net-shape forming, directly producing complex double helical gear structures, significantly reducing machining.Powder metallurgy allows for the direct pressing and forming of complete double helical gear blanks using customized molds.  The tooth profile, tooth direction, and stepped surfaces are formed in a single process, requiring only minimal finishing of the tooth surface (such as fine pressing or grinding) or achieving the required precision directly. Machining volume can be reduced by more than 80%, completely avoiding the multi-step cutting processes required for complex structures.2. Material utilization rate approaches 100%, significantly reducing raw material waste.Powder metallurgy uses quantitative powder filling and pressing, resulting in only a minimal amount of powder waste at the mold closing point. The material utilization rate can reach over 95%, almost achieving "on-demand material usage." Especially in mass production, the raw material saving effect is amplified, which is one of the core cost advantages of powder metallurgy.

3. Integrable auxiliary structures further simplify assembly procedures.In practical applications, double helical gears often require auxiliary structures such as shaft holes, keyways, locating steps, and chamfers. Powder metallurgy allows these structures to be formed integrally with the gear teeth during the pressing process, eliminating the need for subsequent drilling, keyway milling, and other machining operations. This enables one-step forming and direct assembly.
