METHOD AND DEVICE FOR PRODUCING MOLDS FOR TOOTHED BELTS

摘要

A cylindrical die is machined in a workpiece(4) using a rotating grinding disc(9) with a periphery corresponding to the profile of a complete tooth of the belt or the opposing tooth profile of a complete gap in a gear wheel. The die is then used for molding toothed belts or forming gear wheels. An independent claim is made for the process equipment which includes a workpiece holder(3) for rotating a cylindrical workpiece(4) and a grinding tool(9) moving relative to workpiece holder. A dressing tool for the outer profile of the grinding disc ensures the profile always corresponds to a complete tooth of the belt or the opposing profile of a complete tooth gap of a gear wheel.
