An apparatus for profiling a wheelset comprised of a milling cutter with a first axis of rotation, driven friction rollers for rotating the wheelset about a second axis of rotation, and computer numerical control apparatus for rotating the milling cutter about its first axis of rotation while disposing it so that the first axis of rotation is substantially perpendicular to the second axis of rotation.

Apparatus for truing wheelsets

A technique for aligning a wheelset using a wheelset truing machine is disclosed. Using the technique, the wheelset may be aligned by roughly aligning the wheelset truing machine, placing each wheel of the wheelset on at least one roller, determining the distance of tread points on each wheel on the rollers relative to the center of revolution of each wheel by forming measurements and calculations, and coinciding the center of revolution of each wheel with the corresponding setpoint of the machine center. The measurement is taken of the periphery and of the concentricity error and a distance of the tread points determined by the triangulation principle. The technique includes a wheelset aligning device having a locating fixture for locating the wheelset, a measuring device including a-peripheral measuring instrument and a concentricity error measuring instrument, at least two rollers disposed to be swiveled in a x-y plane and to be traversed in a direction perpendicular to the x-y plane on the wheel side of the wheelset to evaluate a respective wheel measurement in the x-y plane by interacting with the wheel thus allowing for coincidence between the respective center of revolution of the wheel and the respective setpoint of the machine center.

Wheelset aligning technique for wheelset truing machinery and wheelset

An apparatus for measuring the contours of a railroad wheel which contains a tool slide, a measuring arm pivotally attached to the tool slide, a measuring wheel rotatably attached to the measuring arm, a device for moving the measuring arm horizontally, vertically, and pivotally, a marker, an optical sensor, and a device for sensing the movement of the measuring arm. The apparatus also contains a first encoder for determining the degree to which the measuring arm moves during any particular time during the rotation of the railroad wheel in any particular rotation cycle, and, additionally, a second encoder for determining at what point in said particular rotation cycle said measuring arm has moved.
