Abstract: A measuring device for the rolling and lathing parameters of railway wheels (1) permitting the viewing of both sides of the flange and the rolling band by means of artificial viewing methods, using two laser light sources (2), each one of which projects a line of light along the profile to be measured. A camera (4) simultaneously captures both sides of the illuminated profile (3) with the aid of a two mirror periscope system (5). The periscope design permits simultaneous viewing of both the flange and the rolling band with a single camera. A set of wheel presence sensors (10) activates image capture by the camera. Each captured image is sent to an electronic artificial viewing equipment (6), where the two profile views containing the recorded image are composed resulting in a complete profile. The obtained results are displayed in the electronic equipment itself or in a computer (7).

Abstract: Device and process for measuring ovalization, buckling, planes and rolling parameters of railway wheels by use of a rolling rail (2) along which the outermost part of the wheel (1) to be measured is made to pass at approximately 10 km/h. Various sensors (7) detect the presence of the wheel in the measuring area, such that they activate the device. A collimated laser beam system (6) projects a solid light beam on the wheel, constantly interfering therewith producing images which are reflected on a screen (4). These images are recorded by a camera (5) and sent to an artificial viewing system (9) where the necessary parameters are calculated, on the basis of which the required measurements are obtained. The results obtained are sent to a computer (10) where the measurement reports are generated.
