The challenge
The manufacturer receives gear orders from OEMs as data sheets or worn samples. They needed 3D models with true involute helical tooth geometry — not approximated — so that their CNC programmers, inspection department and customers all referred to one definition, and they needed it quickly enough to quote.
Our approach
Each gear was defined in KISSsoft from the supplied data: module, tooth count, helix angle and hand, pressure angle, profile shift and face width. Where a mating gear was known, the pair was rated for contact and bending safety and the centre distance was verified before the model was built.
The tooth form was generated from the calculated geometry, with the bore, keyway, web and rim modelled to the customer's drawing practice. LH and RH versions were produced as configurations. Drawings carry the full gear data table — including measurement over pins and span measurement — so the inspector can check the cut gear without recalculating anything.
What was delivered
Models and drawings for each order were delivered within days, as STEP for programming and PDF for the shop. A related job for another gear works provided KISSsoft reports for three helical pairs (2–3.5 module, 22–30T pinions against 76–88T wheels) used as the engineering basis for a gearbox refurbishment quote.
