Helical gear design
Helical gear design
(OP)
I am working on designing a gearbox I am trying to determine what the optimal helix angle I need is and what the optimal face length should be.
besides noise reduction what advantage/disadvantage is there with increasing the helix angle? between say 15deg-20deg. is there an optimal face length depending on what helix angle I have?

... but you really should consult your Dudley Gear Handbook, which you really should have on your desk if you're designing gears.

You'll either spend it on gear design books, gear design experts, or pulverized failed attempts.
Best bet is to buy a gearbox that carries the torque and horsepower required; the factors you mention will have been considered already.
RE: Helical gear design
If noise or dynamic loading (transmission errors) are a concern, for a given helical gear face width you should adjust the helix angle to obtain a suitable face contact ratio, usually >2.0. The face width should be sufficient to meet requirements for tooth bending and contact fatigue stress, as well as providing adequate scoring margin.
