Measuring of rotating shafts angular deformation by means of ultrasonic vibration meter

The task of measuring rotating shafts angular deformation by means ultrasonic vibration meter is considered in the article. Measurement parameters objects an urgent technical diagnostics electromechanical units, turbines, drilling rigs and metal-cutting machines subject to disturbances. measured include their torques arising from torsional vibrations shafting stationary mobile objects. Timely monitoring other factors disturbances frequency shaft beats makes it possible identify defects at early stage eliminate breakdowns that threaten life safety personnel. It was found out reflected acoustic signal phase measurement relative reference one incident onto investigated surface can be carried with error 0.6 % velocities not more than 0.5 m/s. This article intended for mechanical engineers involved development operation
