VERFAHREN UND EINRICHTUNG ZUR BERUEHRUNGSLOSEN VERMESSUNG DES RADPROFILS DER RAEDER VON EISENBAHNRADSAETZEN.

摘要

The measuring system uses a light source (5) directing a light beam onto the wheel periphery parallel to the wheel axis. The profile image of the wheel edge is detected by an optical imaging system, with subsequent digital evaluation. Each wheel (1) passes along a measuring path (2) with the light source radially aligned with a defined measuring position (3) at an acute angle, or perpendicular to the measuring path. The image of the edge profile of the wheel can be detected by a camera (6,7) at an angle (B) to the illumination path.
