Abstract: Method comprising: a) specifying a target ease-off for a first pair of gear wheels from a number of structurally-equivalent gear wheel pairs, b) carrying out a first lapping procedure on the first gear wheel pair, c) carrying out a measurement procedure on the first gear wheel pair to acquire multiple measured values on tooth flanks of both gear wheels, d) ascertaining the actual ease-off of the first gear wheel pair from the measured values, e) ascertaining deviations of the actual ease-off in relation to the target ease-off, f) ascertaining correction values on the basis of the deviations, g) defining an adapted lapping procedure on the basis of the correction values, and h) either carrying out a further, adapted lapping procedure on the first gear wheel pair, i) or carrying out an adapted lapping procedure on a second gear wheel pair from the number of structurally-equivalent gear wheel pairs.

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.

Abstract: A system for determining the suitable positioning of a first gear wheel in relation to a second gear wheel. The system comprises an evaluation unit and a roll-of device, which contains a first spindle for the rotatable seating of the first gear wheel, a second spindle for the rotatable seating of the second gear wheel and a drive mechanism for rotating the first gear wheel and a drive mechanism for acting with a positive or a negative torque on the second gear wheel. The roll-off device furthermore has a displacement device for changing the positioning of the first gear wheel in relation to the second gear wheel. A measurement pick-up device and two angle encoders are provided in the roll-off device and are connected with the evaluation unit.

Abstract: A method and an apparatus are described for optoelectronically determining the contact patterns on tooth flanks of gears. The tooth flanks of at least one gear (24) of a pair of gears (22, 24) to be tested are marked by application of a marking compound. Contact patterns (28) are formed on the points of contact of the tooth flanks during operation. These contact patterns are picked-up and stored as a first digital image. The first digital image serves to determine a second digital image containing the outline of the tooth flank. A third digital image which contains the contact pattern (28) is determined from the first digital image. The second and the third digital images are superimposed on each other to determine a fourth digital image of the tooth flank, which contains the outline thereof and has its contact pattern inscribed therein, and which can be analyzed to determine the position and size of the contact pattern with reference to the outline.
