Helical gears created using Toolbox

[sdb999]

The values for pitch diameter and outside diameter are incorrect according to Machinery's Handbook Edition 24 page 1939. Anyone else come across this? Specifically: 18 tooth, 19.463 Helix Angle, 20 degree pressure angle, 2.0 nominal pitch. Thanks All.

I don't use Toolbox so cannot check. If you have another edition of Machinery's Handbook, double check that it wasn't just a typo. If Toolbox is incorrect you should notify SW for correction.

Another good source of gear details is

Checked another version of Machinery's including the cd rom version. The equations are incorrect and we are taking up with s/w.
