MECHANISM MOVING MEASURING DEVICE Russian patent published in 1997 - IPC

FIELD: measurement technology, measuring machines and instrumentation. SUBSTANCE: mechanism includes base, drive of rotating support of measured part and column placed on base. Column carries carriage mounted for longitudinal translation, transducer is put on carriage. Mechanism also has safety clutch kinematically coupled to output shaft of drive of rotating support, drum put on body of clutch with radial and axial clearances, pins located on body of clutch. Drum has outer helical groove where rope is placed. Ends of rope are anchored in carriage and center point of rope is mechanically fixed on drum. When signal is fed to output shaft it starts rotating and transmits rotation to support with measured part. Part is measured by transducer installed on rod attached to carriage which is coupled by rope via drum to clutch of drive rotating support and can move along guiding column mounted on base from extreme upper to extreme lower positions. EFFECT: improved measuring accuracy and reliability of mechanism. 11 dwg
