Abstract
A system for reprofiling a wheel set of a railway vehicle allows the center of rotation of the wheel set to move relative to supporting rollers. A cutting tool used to reprofile the wheel profile on a wheel set is moved relative to the center of rotation of the wheel set to maintain a constant distance between the center of rotation and the cutter. The rollers are maintained in a fixed position during the cutting process. The system avoids mechanically forcing a constant location of the wheel set relative to the center of rotation.
Claims19
A method for facilitating the reprofiling of a wheel set of a railway vehicle comprising:
- providing a milling station having one or more rollers configured to be maintained in a fixed position and to support a wheel set during a milling process while allowing (i) the wheel set to rotate, (ii) a center of rotation of a wheel to move relative to the one or more rollers and while (iii) preventing radial movement of the rollers by maintaining the rollers in a fixed position relative to the milling station while allowing the rollers to rotate;
- providing a cutting tool operatively connected to the milling station, the cutting tool being moveable relative to said one or more rollers to mill a profile onto a wheel of the wheel set;
- providing a tracker connected to the milling station to track the vertical and horizontal position of the center of rotation;
- and
- providing a control system connected to said milling station and said tracker, the control system including a controller configured to control the position of the cutting tool relative to the center of rotation and to facilitate movement of the cutting tool towards a constant distance from the center of rotation.
