Abstract: The present disclosure relates to a process for machining a gear workpiece (100) comprising a plurality of tooth spaces (6), each of which is defined by two tooth flanks (5.1, 5.2); in said process, a gear tooth-forming tool (1) is used in order to provide at least one subset of all the tooth flanks (5.1, 5.2) with a non-periodically distributed modification of the flank geometry.

Abstract: An apparatus for inspecting and/or measuring a gear wheel workpiece, which comprises: a first workpiece spindle for fastening and rotationally driving the gear wheel workpiece, a rotational drive for rotationally driving the gear wheel workpiece when it is fastened on the first workpiece spindle, measuring means for inspecting and/or measuring the gear wheel workpiece when it is fastened on the first workpiece spindle, wherein the rotational drive is designed to rotationally drive the gear wheel workpiece including the first workpiece spindle during a measurement and/or inspection phase, while the measuring means is used for inspecting and/or measuring the gear wheel workpiece, rotationally drive the gear wheel workpiece including the workpiece spindle during a spinning phase to spin off a liquid.

Abstract: A device (10) for measuring the running behavior of a gear pair having a rolling device (12) which comprises one spindle (15, 16) per gear (13, 14) and has at least one drive (17; 18) for driving one of the gears (13, 14). Furthermore, a structure-borne noise sensor (20), a sequence controller (30), and a speed sensor system (23, 24) are provided. The sequence controller (30) is designed in such way that a combined test of the gear pair may be performed, in which, in a first search run, a specific installation position is ascertained using structure-borne noise testing and subsequently a single-flank working test is performed at the specific installation position.
