PURPOSE: A non-contact shaft power measuring device is provided to measure shaft power without physical contact, thereby measuring the continuous change of shaft power with respect to time without interrupting the movement of a machine during normal operation.;CONSTITUTION: A non-contact shaft power measuring comprises a strain gauge(1), a rotating unit(2), and a fixing unit(3). The strain gauge is attached to a rotary shaft, thereby measuring the distorted deformation of the rotating unit. The rotating unit comprises a housing, a first electronic module, and a second electronic module. The first electronic module comprises a signal converting module(222), an electricity receiving module(223), an electricity converting module(224), and a wireless transmitting module(225). The signal converting module converts measurement signals of the strain gauge into digital data. The wireless transmitting module transmits digital measuring signals received from the signal converting module to the fixing unit by a short distance communication method. The fixing unit is fixed to an external structure and calculates shaft power by receiving the measurement data of the strain gauge from the rotating unit and wirelessly supplies electricity to the rotating unit.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Rotary shaft; (BB) Electricity; (CC) Measurement data
