Abstract (en)

[origin: US4492059A] A grinding device for the reprofiling of a rail of a railway track, comprises at least one grinding unit having a conical grinding wheel rotatably driven by a motor. The motor is secured to a bracket connecting it rigidly to the chamber of a jack whose piston is secured to a rod fixed on the carriage of a railroad vehicle. The jack makes it possible to cause feeding movement of the grinding wheel along a direction parallel to the side profile of the grinding wheel and defining the cutting depth and compensating for wearing away of the grinding wheel. This feeding movement of the grinding wheel takes place along a direction forming an angle with the axis of rotation of the conical grinding wheel, this angle being about half the summit angle of the conical grinding wheel.
