<p>PURPOSE: A device for measuring the torque, a rotating direction, and the rotating speed of a shaft of transmission, especially an output shaft of the azimuth transmission of a wind power plant are provided to measure the large torque slightly distorting the shaft with a simple method due to a diameter of the shaft and properties of materials. CONSTITUTION: A measuring device includes a shaft (1), strips (4,5), measuring sensors (6,7), and hole sensors. The strips are fixed to the circumference (3) of the shaft. The strips are detected by the measuring sensors and measure the torsion of the shaft. The measuring sensors include hole sensors respectively. Each strip is arranged at two different positions on the circumference of the shaft. The strips include polygon through-holes and/or holes. Bridges are arranged between the through-holes and/or holes. The bridges are detected by the measuring sensors.</p> |
