Detailed Product Description

1)Descriptions of Double helical gears
Double helical gears are composed of two sets of symmetrical gear teeth with opposite helix angles (such as left-handed and right-handed), forming a V-shaped tooth profile structure, which is equivalent to the combination of two mirror-image helical gears.
2)Features of Double helical gears
The axial thrust generated by the two rows of helical teeth cancels each other out, thus the bearings inside the gearbox are not affected by the net axial load.
3)Advantages of Double helical gears
a)Automatic balancing of axial force: The reverse helical angle enables self-balancing of axial force, eliminating the need to rely on bearings for counteraction.
b)Extremely low bearing load: The bearings are hardly subjected to axial force, resulting in longer service life and simpler structural design.
c)High load-bearing capacity: The double-tooth meshing ensures a more even distribution of load, enabling the transmission of greater torque and power.
