Core Advantages

Offset Axial Thrust: The symmetrical tooth profile cancels out the axial forces generated by the left and right helical teeth, eliminating the need for additional thrust bearings, simplifying the equipment structure and extending bearing service life;
Heavy-Duty & High-Efficiency Transmission: With long tooth contact lines and high contact ratio (multiple teeth meshing simultaneously), they offer significantly higher load-bearing capacity and impact resistance than spur gears, enabling transmission of greater torque and power;
Stable & Low-Noise Operation: The progressive meshing design reduces vibration and impact, resulting in much lower operating noise than spur gears and ordinary helical gears, making them suitable for high-speed applications;
Strong Adaptability: Excellent lubrication fluidity and large misalignment tolerance can compensate for slight installation deviations, reducing wear risks and improving transmission efficiency.

Common Raw Materials

Alloy Structural Steel: Such as 40Cr, 20CrMnTi, featuring high strength, good toughness and hardenability. With heat treatment, it exhibits excellent wear resistance, suitable for general heavy-duty scenarios (e.g., reducers, mining machinery);
Carburized Alloy Steel: Such as 20CrNiMo, 17CrNiMo6. After carburizing treatment, it has high tooth surface hardness and strong core toughness, with outstanding fatigue resistance and impact resistance, ideal for high-speed and heavy-duty equipment (e.g., wind turbine gearboxes, rail transit transmission systems);
Stainless Steel: Such as 304, 316L, offering excellent corrosion resistance and rust prevention, suitable for humid and corrosive environments (e.g., marine propulsion systems, chemical machinery);
Engineering Plastics: Such as PA66+glass fiber, POM, characterized by light weight, low noise and good self-lubrication, suitable for low-load, high-speed and silent scenarios (e.g., small robot joints, precision instrument transmission).

Application Scenarios

Widely used in high-power, high-speed and heavy-duty transmission systems, including wind power equipment, marine propulsion systems, rolling mills, mining machinery, heavy-duty reducers, automotive differentials, rail transit gearboxes and robot joint transmissions, etc.
