APPARATUS FOR DIAGNOSING DAMAGE OF POWER TRANSFER UNIT IN HOT ROLLING MILL EQUIPMENT

摘要

An abnormality diagnosis apparatus for a power transmission system in a hot rolling facility is provided. An abnormality diagnosis apparatus for a power transmission system is provided with a rolling roll and an apparatus for diagnosing an abnormality of a power transmission system in a hot rolling facility including a power transmission system that is connected to one end of a rolling roll through a spindle to rotate the rolling roll, The first displacement sensor is spaced a predetermined distance from the spindle and is spaced from the first displacement sensor at a predetermined angle in the circumferential direction of the spindle to measure the distance between the spindle and the spindle. A monitoring unit for obtaining an axis motion locus of the spindle in which the distance measured by the first displacement sensor is the X axis and the distance measured by the second displacement sensor is the Y axis as the spindle rotates; And a diagnosing unit for diagnosing an abnormality of the power transmission system by comparing the axis motion locus of the spindle obtained in the step S11 with the reference motion locus of the normal time stored in advance to diagnose the abnormality of the power transmission system early, It is possible to prevent a rolling equipment accident and loss of life.
