This WCP gear calculator has the same mistake.
Out of curiosity, how exactly do these gears work? How does the PD remain the same with fewer teeth? |
Good catch, fixed it now.
The gears are addendum modified, which is where the addendum, and in some cases the dedendum is altered from its nominal dimension. This adjusts the shape of the gear tooth, and can be used to alter pitch diameter, reduce undercut, create stub teeth, etc. Paul Copioli had a few posts this fall, detailing more of whats going there.
