Involute spline generator?

You can generate downloadable dxf files for involute gears at me-bac.com. Bottom of the page is a spur gear calculator. Input number of teeth, module, pressure angle, rack shift coefficient, and coefficient of fillet radius. Put in the torque and face width and it also calculates the tooth root bending stress with the Lewis method if there is no undercut.

The table of results provides:
  • the minimum and the maximum rack shift coefficient (x/mmin and x/mmax);
  • the reference diameter (d);
  • the base diameter (db);
  • the involute tooth limit diameter (dlim);
  • the root diameter (df);
  • the addendum diameter (dt);
  • the tooth root bending stress at point T (σF);
  • ...
