Involute curve for a profile shifted spur gear 1

[nelk]

Hi

ive attached two equations that describe an arbitrary point on an involute curve.

but how are the equations derived in terms of number of teeth (z), Module (m) , profileshift (X) and involutangle (theta).

I did this some years back and it was a Mathcad file. Look it over, maybe you can make use of some of it.

Sorry, good question - didn't think of it.
