In the spite of arising novel and performant involute gear cutting technologies, gear-hobs stays as most popular and widespread gear cutting tool. Numerous theoretical research was performed for perfectioning this cutting tool, but nowadays it still results with a theoretical profile error. This error changes with the number of re-sharpenings and by this it induces a variable profile error on the machined gear. The present paper deals with a data processing and computing method which makes possible the numerical definition of the cutting edges, with adequate precision. Using this, the modelling of the limiting surfaces of the meshing surface of the cutting tool becomes possible.
Kivonat
A modul csigamaró, annak ellenére, hogy új technológiák is sikeresen jelennek meg, az evolvens hengeres külső hajtópár leggyakrabban alkalmazott lefejtő szerszáma. Számos kutatás és tanulmány ellenére, e szerszám elméleti profilhibával készül. Az elméleti profilhiba az élezések során változik, és ez által a gyártott fogaskerék profilhibáját befolyásolja. Jelen dolgozat célja egy olyan mérési és adatfeldolgozási eljárás ismertetése, amelynek eredményeképpen számszerűen, megfelelő pontossággal, meghatározhatóvá válnak a csigamaró valós élei. Ezekkel a továbbiakban a lefejtő határfelületek modellezése lehetővé válik.
