Eccentricity errors - correcting device and method for eccentricity errors - correction in the case of an acceleration sensor in an acceleration in the direction of production

摘要

Eccentricity errors - correction means for an acceleration in the direction of generating includes a rotation-type, comprising a rotary table (1) of a large diameter, which by means of a first servomotor (6) is rotatable, and a turntable (9) of a small diameter, which, on an outer peripheral portion of the turntable (1) of a large diameter, and is mounted by means of a second servo motor (11) is rotatable, wherein an acceleration sensor (20) on the turntable (9) can be fastened by a small diameter and the eccentricity error - correction means includes means for removing a mean value - component which can only the mean value - component from an output signal of the turntable (9) of a small diameter acceleration sensor (20) attached removed.
