Device automatic measurement of residual stresses in the rim of a wheel mounted on a set of railroad wheels.

摘要

WHEEL (54) rests on a rail (50). CHASSIS (1) MOUNTED ON MEDIA SUPPORT AND LIFTING (6.6 '') has slideways ARRANGED BY BOTH SIDES OF RAIL (50) and parallel to the rail (50). TWO CARS ARE MOUNTED ON MOBILE translationally GUIDES LANDSLIDE. TRUCKS ARE MOUNTED ON MOBILE translationally in a direction perpendicular to the slideways, GRINDING DEVICES (12), CONTROL DEVICE FOR ULTRASOUND (131) and two proximity sensors. IS PERFORMED timekeeping ultrasound propagation on the rim (54A) in two perpendicular directions and measuring the width of the tire (54A). CALCULATED AND COMPARING THE SPEEDS OF ULTRASOUND PROPAGATION IN ORDER TO DETERMINE THE STATE OF TENSION rim (54A).
