METHOD FOR CORRECTING UNBALANCE OF ROTATOR

摘要

PROBLEM TO BE SOLVED: To reduce the frequency of working necessary for the correction of an unbalance and set the magnitude of acceleration within a standard by performing the working once or twice. SOLUTION: This method comprises a first measuring process of measuring the magnitude and phase of acceleration; processes of reading correction quantity and correcting direction from correction quantity and correcting direction maps; a first working process of working a rotator to correct the unbalance; a second measuring process of remeasuring the magnitude and phase of the acceleration; processes of renewing the correction quantity within the correction quantity map and the correcting direction within the correcting direction map; processes of reading correction quantity and correcting direction from the renewed correction quantity map and correcting direction map by use of the magnitude and phase of the acceleration measured in the second measuring process with retrieval keys; and a process of reworking the rotator on the basis of the correction quantity and correcting direction read from the renewed maps to correct the unbalance.
