5.2 DOUBLE HELICAL GEAR AND HERRING BONE GEARS Figure 5.2 shows a
double helical gear. Two helical gears of opposite helix cut on a gear blank with
a small gap are known as double helical gears. If the two gears are cut without ...

Gear Drive Systems: Design and Application
A double helical gear with a face width/pitch diameter ratio of 1 will have twice
the face width of a spur or single helical gear with the same L/D ratio and
therefore greater load-carrying capability. Double helical gearing has two
disadvantages.

Gear Design
... then obviously this cannot be done in case of a double helical gear. In case of
axial thrusts, if both the shafts have to sustain large axial loads caused by some
extraneous source, the single helical gears are preferable as the tooth pressure ...

Handbook of Practical
Gear Design
There may be resistance to axial float resulting from friction in coupling devices. If
there is enough resistance to axial movement, the division of load in a double
helical gear may be impaired. A 30° helix angle, or higher, is needed in the
double ...

Gas Turbine Engineering Handbook
When both helices of a double-helical gear are cut at the same time, or
sequentially without a change in setup, apex position error will be virtually
unobservable in operation, and axial vibration excitation from the mesh will be
negligible.

Double Helical (Herringbone). A way to counter the thrust loads of the helical
gear is the double helical gear. This is accomplished by dividing the face width of
the gear into two halves and using the opposite hand of helix for each half. In
