1) Descriptions of  Double Helix Gears
The double helix gears adopt a symmetrical layout. The helical teeth of the two groups have opposite rotations (one left and one right), and their tooth profiles are arranged in a V-shape, similar to the interlocking helical gears placed back-to-back.
2) Characteristics of  Double Helix Gears

When gears are in operation, the axial forces of the helical teeth on both sides counteract each other, so the bearing does not need to bear additional axial loads.
3) Advantages of  Double Helix Gears

• Axial force self-compensation: The reverse helical design enables the thrust force to be automatically neutralized within the gear.
• Extended bearing life: The axial stress on the bearing is nearly zero, reducing maintenance requirements.
• Efficient power transmission: Dual-tooth synchronous meshing enhances the uniformity of load distribution, suitable for high-power applications.
