METHOD AND APPARATUS FOR COMPENSATING ERROR DUE TO WHEEL-CALIBRATION IN GEAR CONTROL AND DIGITAL GEAR CHECKING APPARATUS

摘要

The invention relates to a method and apparatus for compensating for error in a gear wheel in a gear check apparatus. An assembly is used in which the wheel 14 is mounted. A TEST IS MOUNTED ON A SHAFT 18 CONNECTED TO AN ENCODER 26 AND ENGRENE WITH A STANDARD WHEEL 12 CONNECTED TO AN ENCODER 24. A TEST SIGNAL, CORRESPONDING TO A DIFFERENTIAL MOVEMENT BETWEEN THE WHEEL-CALIBRATION AND THE WHEEL A TEST, DUE TO THE PRESENCE OF IMPERFECTIONS OR IRREGULARITIES OF BOTH WHEELS, IS THEN TREATED TO GIVE SEVERAL INDIVIDUAL ERROR VALUES CORRESPONDING EACH TO THE ENGRENAGE OF A GIVEN DATA OF THE WHEEL-ETALON WITH SEVERAL TEETH THE WHEEL ON TESTING. / P P FIELD OF APPLICATION: CHECKING AND CHECKING THE GEARS. / P
