METHOD FOR THE ELIMINATION OF MAZAROTS AND THE RECTIFICATION OF RAILWAY WHEELS.

摘要

MAZAROTH IS REMOVED FROM A CAST STEEL RAILWAY WHEEL (34) USING A GRINDING WHEEL (168) WHEN THE WHEEL (34) HAS COOLED FROM ITS INITIAL CASTING TEMPERATURE AROUND 425-650 (DEGREES) C. A RAILWAY WHEEL SUPPORT KIT INCLUDES A ROLLER KIT (62, 64, 100, 110) TO RECEIVE AND COLLECT THE RAILWAY WHEEL (34) AND ROTATE THE RAILWAY WHEEL (34) ON ITS CENTRAL AXLE. A MOTOR (160) STEERING A GRINDING WHEEL (168) IS MOUNTED ON A SUPPORT EQUIPMENT (122). THE RAILWAY WHEEL SUPPORT EQUIPMENT SWINGS ON AN AXLE EQUIPMENT (70, 72) DURING GRINDING. THE GRINDING TEAM ADVANCES THE GRINDING WHEEL (168) LATERALLY ON THE RAILWAY WHEEL DURING GRINDING. THE SIDE ADVANCE OF THE GRINDING WHEEL (168) AND THE SWING OF THE RAILWAY WHEEL (34) ARE CONTROLLED TO PERFORM A LAST GRINDING OF THE SELECTED SURFACE OF THE RAILWAY WHEEL (34) WITH A PRESET CONTOUR.
