WHEEL INNER SURFACE DISTANCE MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To enable the reduction of labor and time required for measurement by improving measurement efficiency with a simple structure.SOLUTION: A wheel inner surface distance measurement device 1 for measuring an inner surface distance of wheels of a railway vehicle comprises: a horizontal guide rail 5 for placing a wheel 2 thereon and supporting a traveling rail 3 movably in a track gauge direction X; a load lateral pressure part 6 for applying lateral pressure in the track gauge direction X to the wheel 2; a wheel displacement measurement part 7 for measuring the displacement in the track gauge direction X of the wheel 2; a load lateral pressure measurement part 8 for measuring load lateral pressure applied in the track gauge direction X of the wheel 2; and a wheel pressing part 4 for holding the wheel 2 on the traveling rail 3 in the track gauge direction X. A support base 41 comprising the traveling rail 3 is provided in the wheel pressing part 4. The load lateral pressure part 6 presses the support base 41 movably along the horizontal guide rail 5 toward a track gauge outer side X2 and a track gauge inner side X1.
