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 system avoids mechanically forcing a constant location of the wheel set relative to the center of rotation.
Claims20
An apparatus for reprofiling a wheel set of a railway vehicle comprising:
- a milling station having one or more rollers supported on stationary brackets anchored to said milling station, the stationary brackets configured to prevent axial and radial translation of the one or more rollers relative to said milling station such that the one or more rollers rotate relative to the stationary brackets and support the wheel set while allowing the wheel set to rotate and while allowing a center of rotation of the wheel to move relative to the one or more rollers, the one or more rollers allowing the wheel set to rotate while cutting a wheel of said wheel set;
- a cutting tool operatively connected to the milling station, the cutting tool being moveable relative to said one or more rollers and positioned to mill a profile onto the wheel of the wheel set;
- a tracker connected to the milling station to track the position of the center of rotation;
- and
- a controller connected to said milling station and said tracker, the controller for controlling 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.
