FIELD: the invention is designed for ultra sound control of the axles of wheel pairs.
SUBSTANCE: they introduce ultra sound vibrations at different angles into the rotating axis with the aid of the converters of ultra sound vibrations, receive echo-signals, according to the parameters they define the quality of the axis, at that they install the converters under the part of the pre under stage and turn them relatively to the geometric axis in such a way that radiation of the first converter is directed on the part of the neck of the axis located in the zone of the interval between the two bearings, radiation of the second converter is directed into the field of the hollow chamber between the part of the pre under stage and the axis of neck, and the reflected signal is received with the third converter, radiation of the fourth - into the axis located in the zone of exterior edge of the hub, radiation of the fifth - into the part of the axis located in the zone of the inner edge of the hub, radiation of the sixth is directed perpendicularly to the geometrical axis, at that the first and the fourth-the sixth converters are fulfilled in the shape of receiving-transmitting converters, the introduction angles are changed in diapason 0-650, and the turning angles are changed in the diapason of 0-600.
EFFECT: exclusion of carrying out complex preparatory operations.
