DEVICE FOR MEASURING TORQUE ROTATIONAL DIRECTION AND ROTATIONAL SPEED OF A SHAFT OF A TRANSMISSION PARTICULARLY AN OUTPUT SHAFT OF AN AZIMUTH TRANSMISSION OF A WIND POWER PLANT

摘要

The present invention is a device for measuring the torque, rotational direction and rotational speed of a shaft 1 of a transmission 2, in particular an output shaft of an azimuth transmission, wherein the strips 4, 5 are provided on the outer circumference 3 of the shaft 1 This position can be fixedly mounted, the strips can be detected by measurement sensors 6, 7 and allow to measure the torsion of the shaft 1, the measurement sensors 6, 7 Each includes one Hall sensor 8, one strip 4, 5 is disposed at two different positions of the outer periphery 3 of the shaft 1, the strip being polygonal through holes 9 And / or grooves 10, bridges 11 are disposed between the through holes 9 and / or grooves 10, the bridges can be detected by measurement sensors 6, 7. That is, it relates to a measuring device. In addition, a method for operating the measuring device 1 for torque, rotational direction and rotational speed of the shaft 1 is claimed.
