I made two herringbone gears with the same helix, but different number of teeth. Unfortunately, they don't match. How to calculate helix pitch properly to match two gears?

Re: How to match herringbone gears?
To get the same gradient in movement direction of the helix I think you must scale the radius and pitch in an equal manner. This means if you halfe your radius you also need to half your pitch etc.

Check your gear dimension calculation, maybe something is missing.

Shouldn't those gears be the same thickness?

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting.

I use this to compute the helix:
beta is the angle of the cutting rack rotation.
Code: Select all
angle=height * tan(beta) * gear_radius
auxspine = makeHelix(height * 2 * pi / abs(angle), height, 10., 0, bool(angle < 0))

Re: How to match herringbone gears?
Just scale the helix pitch proportional to the teeth number
