Are you sick of tooth approximations that just
do not fit in your model. Here is my answer. The involute profile is approximated by a spline with 10 points minimum.
| The Real Involute Gear Profile | Right mouse pick - save as |
Involute Gear, Use as a template, not an iPart. 12 tooth to 400 tooth. Diametral pitch -- 1/2 to 36, pressure angle 14 1/2, 20 and 25 degrees.
Yes, there is a extra spread sheet for doing the bores and keyways. |  |
| Internal Involute Gear, As above but. 24 tooth to 400 tooth. Diametral pitch -- 1/2 to 36, pressure angle 14 1/2, 20 and 25 degrees |  |
