Abstract
A gear production plant has, along a gear production path, a station for preparing a number of blanks; a cutting station, where respective teeth are cut on the blanks to obtain a number of semifinished parts; a heat treating station, where the toothed semifinished parts are carburized or nitrided; and a finish station for finish machining the heat treated semifinished parts; the plant also having a check station located along the production path, downstream from the heat treating station or the finish station, and which houses an optical measuring unit for non-destructively determining the effective carburized or nitrided case depth on the teeth.
Claims5
A gear production plant comprising,
- along a gear production path,
- a station for preparing a number of blanks;
- a cutting station, where respective teeth are cut on the blanks to obtain a number of semifinished parts;
- a heat treating station, where the toothed semifinished parts are carburized or nitrided;
- and
- a finish station for finish machining the heat treated semifinished parts;
- the plant also comprising a first check station, located along said production path, downstream from said heat treating station or said finish station;
- said check station at least partly housing optical measuring means for non-destructively determining the carburized or nitrided case depth of said teeth without mechanical contact of the measuring means with the teeth.
