<p>The present invention relates to a method for relatively stabilising the position of a rotating part axis using multi-stepped self-adjusting prismatic supports. The inclinations of the geometrical shape of the cylindrical part are measured using an out-of-round gauge having a first (9), a second (14) and a third (18) measuring sensors fitted therein. The out-of-round gauge is arranged on a mount (12) which is capable of displacement along the rotating part. During the rotation of the part, the sensor (9) is used for measuring the changes in the non-roundness of the profile of the part cross section, while the sensor (14) is used for measuring the radial beating of the centre of the profile average circumference. When the out-of-round gauge moves along the rotating part, the sensor (9) measures the non-roundness of the cross section profiles as well as the changes in the radius of the average circumference of said profiles, while the sensor (14) measures the beatings of the average circumference centres. According to the value of these measures, the geometrical shape of the longitudinal section profile of the part can be determined together with the straightness of the part axis. The correction steady comprises a rocker arm with self-adjusting main supports as well as a secondary support for compensating weight which is mounted on a sliding member. The rocker arm is mounted in the body of the steady so as to be capable of rotation about the axis and of vertical displacement. The main supports are hinged to the axes at the ends of the rocker arm, while the secondary support in made in the shape of analog prism and is mounted on the sliding member. The sliding member is arranged at a given angle relative to the vertical and is mounted so as to be capable of linear displacement within the body of the steady.</p> |
