Double Helical Gears High-Performance Power Transmission With Customizable Tooth Profile

1)Descriptions of Double Helical Gear
A double helical gear is a type of gear composed of two sets of helical teeth with opposite directions.

Its tooth profile is symmetrically distributed, similar to a herringbone gear, but it usually has a central cutting-edge recess for ease of processing.
2)Features of Double Helical Gear

a) It is composed of left-handed and right-handed helical gears arranged in opposite directions,

    with a processing groove left in the middle (partially designed as a seamless continuous structure).

b) When the helical gears mesh, axial forces are generated.

    However, the symmetrical layout of the double helical gears cancels out the axial forces on the left and right sides.

3)Advantages of Double Helical Gear
a) Axial force self-balancing: No need for additional thrust bearings, simplifies the support structure, and reduces system complexity.

b) High load-bearing capacity: The multi-tooth simultaneous engagement characteristic of helical gears ensures a more even

    distribution of load, making them suitable for high-power transmissions.
