DIN 18CrNiMo7 Steel 4 Module 77T Double Helical Gears For Gearbox

1) Description of Double Helix Gears

A double helical gear consists of two helix angles with opposite hands. Inside the gears, the axial thrusts oppose each other

and the resulting forces are not transmitted to the bearings on the shaft. This gearpair setup means they can handle high loads

and allow for a solid transmission while running.

2) Features of Double Helix Gears

Double helical gears have all of the advantages of helical gears, which are strong and quiet, plus have the advantage of being able to

cancel the thrust forces by combining helical gears with both right and left hand twists.
