ABSTRACT:
An apparatus for locating the center of rotation of a wheelset. The apparatus contains two movable roller assemblies each designed to establish circumferential contact with a wheel at a different location on the wheel periphery, a movable lifting device connected to each such roller assembly, encoders for determining the extent to which each of the movable roller assemblies is moved in a linear direction during rotation of the wheel of the wheelset while in contact with the wheel, and an encoder for determining the extent to which the wheel of such wheelset moves in the x and y axes axis during rotation of the wheel about its centrally mounted axes.
