Modelling and prevention of meshing interference in gear skiving of internal gears

Abstract Gear skiving is a highly productive process for machining of internal gears which are required in large quantity electric mobility transmissions. Due to the complex kinematics gear skiving, collisions tool and workpiece can occur during process. Models exist check shank or run-out. While these models sufficient design external at meshing interferences between appear outside contact plane on clearance face tool. To test interference requires comprehensive assessment workpiece, kinematics. Currently, this often done by time consuming CAD-simulation. In contrast, paper presents an automated geometrical model analysis interference. The thereby performed along whole height especially includes constructive angles eccentric positions. developed user-friendly implementation practical applications. avoiding validated two different doing so, influences situation investigated, compared discussed. Furthermore new approach enables prevention tooth tip early adjusting itself. maximal viable be quantified recommendations improving suggested.
