- Thread starter soo74
- Start date
The fHa is the alignment error of a best straight line drawn from the start of the active profile to the end of the active profile of a charted gear tooth involute. Of itself, it doesn't tell you much unless you take the form variation (ffa) and the required quality of the charted involute into consideration with it.
I hope that helps.
