Device for measuring torque, direction of rotation and Drehverwidigkeit a shaft of a transmission, in particular an output shaft of an azimuth gear of a wind turbine

摘要

The invention relates to a device for measuring torque, direction of rotation and rotational speed of a shaft (1) of a transmission (2), in particular an output shaft of an azimuth gear, wherein on an outer circumference (3) of the shaft (1) bands (4, 5) positionally fixable are detectable by measuring sensors (6, 7) and make a torsion of the shaft (1) measurable, wherein the measuring sensors (6, 7) each have a Hall sensor (8) and at two different positions of the outer periphery (3) the shaft (1) is arranged in each case a band (4, 5) which comprises polygonal openings (9) and / or depressions (10), wherein webs (11) are arranged between the openings (9) and / or depressions (10). located, which are detectable via measuring sensors (6, 7). Furthermore, a method for operating a device (1) for measuring torque, direction of rotation and rotational speed of a shaft (1) is claimed.
