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
