BALANCE ADJUSTMENT METHOD OF ROTATING BODY

摘要

PROBLEM TO BE SOLVED: To shorten a time necessary for adjustment in the balance adjustment of a rotating body.SOLUTION: A balance adjustment method of a rotating body comprises: a member assembling step S2 of assembling a member to be assembled to a revolving shaft; a first displacement measuring step S3 of measuring an axial displacement distribution of the member to be assembled that has been assembled to the revolving shaft, along the circumferential direction; an inclination amount calculation step S4 of calculating an inclination amount of the member to be assembled with respect to the revolving shaft; and an adjusting step S5 of adjusting weight that is calculated on the basis of the inclination amount using a distance Lobtained in the following expression (1). In the expression (1), Lis a distance (mm) from a base point of an inclination to one face; Lis a distance (mm) from a base point of the inclination to the center of gravity of the member to be assembled; Iis the polar moment of inertia(kg-mm); Iis the diameter moment of inertia(kg-mm); and m is the mass (kg) of the member to be assembled.
