DIAGNOSES OF THE OPERATIONAL ERRORS OF A THREADED-WHEEL GRINDER IN THE GRINDING OF SPUR GEARS USING KINEMATIC TRANSMISSION ERRORS

The kinematic transmission errors of spur gears can be detected by a s ingle flank rolling test. This rolling test can be performed very quic kly and requires little operator skill, so it is suitable for the diag noses of manufacturing errors. This paper uses the conjugate shape gen eration method to construct the mathematical model of tooth profiles o f spur gears that were ground in a threaded-wheel gear-grinder with op erational errors. A single flank rolling test simulator is developed t o investigate the relationships between the operational errors and the kinematic transmission errors. The diagnostic equations are derived u sing this simulator. The validity of this simulator is verified experi mentally. (C) 1998 Elsevier Science S.A.
