Abstract:
1. A torque sensor that comprises two parallel, axially opposite, disc-shaped, fastening flanges ( 1 , 2 ), which are rigidly connected with one another by a radially inwardly lying torque transmission element ( 3 ), whereby one fastening flange ( 2 ) is embodied as a measuring flange, which comprises several imperforate blind pocket recesses ( 5 , 5 ′) on a coaxial encircling area that extends radially between a radially outer fastening ring surface ( 10 ) of the measuring flange and the radially inwardly lying torque transmission element ( 3 ), shear force transducers ( 20 ) are applied on blind floor surfaces ( 15 ) in the blind pocket recesses or on outer surfaces ( 19 ) on a backside of the blind floor surfaces of the pocket recesses ( 5 , 5 ′), and the coaxial encircling area of the measuring flange further comprises at least three radial stiffening webs ( 6 ) at positions respectively circumferentially between and separating the blind pocket recesses from one another, wherein the coaxial encircling area of the measuring flange ( 2 ) is a solid axially imperforate disc that is circumferentially and radially continuous and that extends radially from the radially inwardly lying torque transmission element to the radially outer fastening ring surface ( 10 ).
