Abstract
In an apparatus for measuring the eccentricity of an eccentric bearing face having an axis of rotation, a rotary motion and a perimeter, the apparatus comprises a length measurement gauge, mounting means for mounting the length measurement gauge, means for guiding the movement of the length measurement gauge, in which the guiding means comprises a follower and two bearing tips, and means for applying the bearing tips to the eccentric bearing face. The mounting means for mounting the length measurement gauge functions to (a) maintain the length measurement gauge in the radical direction during rotary motion, and (b) enable the length measurement gauge to move perpendicularly to the axis of rotation. The guiding means functions to guide the movement of the length measurement gauge in the direction of the rotary motion of the eccentric bearing face. The guiding means comprises a follower, which is able to move radially with respect to the bearing face, and two bearing tips at a distance to one another along the perimeter of the eccentric bearing face. The follower is coupled to the length measurement gauge in the direction of its movement perpendicular to the axis of rotation.
