The grinding worm, profiling gear and method for the profiling of the grinding worm

摘要

In a method for the profiling of a grinding worm (1) with at least two grinding wide regions (4, 6) with differently modified gear profile for the grinding of spur gears with three-dimensionally be modified flank profile for the purpose of optimum utilization of the grinding worms width (3) the grinding wide regions (4, 6) arranged to engage in each other in. For the profiling of the grinding worm (1) serves, in a variant, a hard substance profiling gear (25) and covered with a deviating from the workpiece to be abraded and the tooth width resulting. By suitable selection of the diagonally ratio and the assignment of the areas of the width (28, 29) of the the profiling (25) to the grinding wide regions (4, 6) of the grinding worm (1) during the profiling, it is possible, the modifications of the grinding worms flanks of the needs of the workpiece, without the flank geometry of the the profiling (25) having to be changed. In another variant embodiment, the grinding worm (1) in a first step, over its entire width (3) with the desired profile shape of the profiled roughing region, and in a second step, of a grinding region (36, 37) and the adjacent transition regions (34, 35) of the right - and the left flank of the grinding worm (1) by means of nc - controlled lines profiling with a the form of dressing roller (40) completely profiled.
