Abstract

Provided is a method for measuring the state of a rotary member that is capable of rotating about a rotary member axis line. The method comprises: a step for disposing a measuring device on a measurement surface of a rotary member; a step for disposing the rotary member at a given measurement angle of which the center is located at a rotary member axis line; a step for disposing a support member for the measuring device so as to enable an angle detector of the measuring device to detect a rotational angle which corresponds to said measurement angle and of which the center is located at a support member axis line; a step for measuring, by means of an inclination detector of the measuring device, the inclination angle of the inclination detector with respect to a measurement reference surface at the rotational angle of the support member; and a step for measuring the state of the rotary member at least on the basis of the inclination angle.

A method for measuring a state of a rotary member rotatable about a rotary member axis line, the method comprising the steps of:

disposing a measuring device on a measurement surface of the rotary member, the measuring device including:
a rotating mechanism;
a support member that can be rotated about a support member axis line by the rotating mechanism;
an angle detector that detects a rotation angle of the support member;
and an inclination detector that is disposed on the support member and detects an inclination angle of the inclination detector with respect to a measurement reference surface;
disposing the rotary member at a first measurement angle centered on the rotary member axis line;
disposing the support member such that a first rotation angle centered on the support member axis line corresponding to the first measurement angle is detected by the angle detector;
measuring a first inclination angle of the inclination detector with respect to the measurement reference surface at the first rotation angle of the support member by the inclination detector;
and
measuring the state of the rotary member based on at least the first inclination angle.
