Measure across the tips of two opposite teeth. A caliper is accurate enough.
Count them. This is the one number that must be exact.

The face width of the gear: the thickness of the plate it is cut from.

What you get

  • A cut-ready DXF: true involute flanks and a true trochoidal root, not an arc approximation.
  • Two ratings, each the lower of ISO 6336 root bending and ISO 6336 pitting.
  • The conditions those ratings hold under, printed on the file.

Why this one is different

  • 1Starts from the gear in your handOutside diameter, tooth count and plate thickness: a caliper and a count. The engine works out the module and any profile shift itself. There is no diametral pitch or module table to look up.
  • 2Rated, not just drawnMost gear generators stop at the outline. Every gear here carries a torque rating for root bending and for pitting, worked to ISO 6336 methods. The lower of the two is the one published.
  • 3Rated for how you cut itLaser, waterjet, wire EDM, hob or shaper. The speed rating follows the accuracy of the process you choose. A thermal cut is rated at its ISO 9013 roughness, on a tooth thinned to the edge of the cut tolerance.
  • 4The method is checked, not assumedThe ISO bending method was checked against our own finite-element model of the tooth root, from 14 to 90 teeth. It came out on the safe side at every count.
  • 5Says no, and says whyIf a gear cannot be cut or rated, you are not given a guess. The generator tells you which number to change, and what to change it to.
  • 6Free, no sign-upDownload the DXF with its rating and conditions printed on it.

How are these checked? The methods, the validation and what we deliberately do not claim, for gears and sprockets alike.

Result

A sample gear is filled in. Change the three numbers to yours and press Rate this gear. A result takes a few seconds: the rack cutter is rolled past the blank, not looked up.

Mounting it?

The same engine rates weld-on and bolt-on tabs for shafts, frames and pipe work, with FEA-checked drawings.
