Gear Profile Tolerances

App to calculate the gear profile tolerances according DIN3961 / ISO 1328

This tool will calculate the profile allowable deviations based in the different quality level of the gear.

Using the module, teeth number, helix and gear width the app calculate the following parameters:

fi``: Single Flank Working Deviation

Fi'': Two flank working deviation

fHa: Profile angle deviation

ffa: Profile form deviation

Fa: Total profile deviation

fHb: Helix angle deviation

ffb; Helix form deviation

Fb: Total helox deviation

fu: Pitch variation error

fp: Single pitch deviation

Fp: Total pitch deviation

All values are in microns.

After having the first calculation performed you can move along the different quality numbers available and compare the values.

The app can also save and share the middle column quality values.
