profilo dente ad evolvente

[tano]

Hello everyone, I have been using nx for a few months, in my thesis work I was asked to build an evolving tooth, but the evolving must be as precise as possible. I don't know how to insert the formula of the evolved inside nx.... I hope someone can help me either in entering the formula or if there is another method that I can follow for building the evolved. Thank you.

insert the formula and see what you can't do.

from wikipedia, the formula should be:
its coordinates given in parametric form are:

x=a(\cos{t}+t\sin{t})
y=a(\sin{t}-t\cos{t})

I'm also trying to insert that formula coma law curves but I don't know exactly where to start

Hi, found on the internet, see if it's your case.View attachment gear_generator.7z
