Helical Gear

Our 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 helical gears 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

(1) Complex helical gear profiles are formed in a single step-eliminating the need for subsequent machining processes such as gear hobbing or shaping. The mold directly presses out the precise helix angle，reducing production time by more than 50% compared to machining. Near-net shape forming results in material utilization greater than 95%-with no cutting waste, making it particularly suitable for gears made of precious metals or difficult-to-machine materials, significantly reducing raw material costs.

(2) Excellent batch consistency-through mold replication, the cumulative pitch error of gears in the same batch is less than 0.03mm, making it ideal for large-scale standardized production in industries such as automotive and home appliances.Complex structures can be integrated-features such as shaft holes, keyways, and weight-reducing holes can be pressed out simultaneously, reducing subsequent assembly steps and improving overall component integrity.

(3) Self-lubrication potential-controllable porosity can be maintained and impregnated with lubricating oil, enabling long-life, maintenance-free operation, especially suitable for enclosed gearboxes.

These advantages allow powder metallurgy helical gears to rapidly replace traditional gears in fields such as automotive transmissions, power tools, office equipment, and home appliances, with significant cost advantages, especially in scenarios with annual production exceeding 100,000 units.
