Double Helical Gear

High Precision Double Helical Gear

Double helical gears are a variation of helical gears in which two helical faces are placed next to each other with a gap separating them. Each face has identical but opposite helix angles. Employing a double-helical set of gears eliminates thrust loads and offers the possibility of even more significant tooth overlap and smoother operation. Double helical gears are commonly used in enclosed gear drives as helical gear.
Due to its advantages of high load capacity and stable transmission, double helical gears have been widely used in the power transmission of gas turbines, generators, prime movers, pumps, fans and compressors in ships and construction machinery.

As one of the leading double helical gear manufacturers, suppliers, and exporters of mechanical products, We offer double helical gear and many other products.Please get in touch with us for details.

A double helical gear incorporates two opposite orientated helical gears of the same helix angle together such that the two opposing thrust forces annihilate one another. For many years such double helical gears, as an example for components with geometrical interference, have been a challenge in finishing gears. While military low lot size applications might have been the main focus in the past, there is now a current boost in demand for double helical gears in planetary reduction gearboxes for engines in civil aviation. Increasing weight reduction and fuel-saving requirements lead to decreasing sizes of design firms.
