NONCONTACT TYPE MEASURING DEVICE FOR TORQUE OR ANGLE OF TORSION

摘要

1. Contactless measuring device for torque and/or angle of rotation on stationary or rotating shafts (10), comprising two preferably cylindrical bodies (20, 21) which are concentric to the shaft (10), are attached, with their respective end areas, to the shaft to rotate therewith and can be turned with respect to one another, also comprising a measuring system (19a, 19b) which determines from the relative position of the two bodies (20, 21), which changes with the turning angle, the torque and/or the angle of rotation transmitted form the shaft (10) over a pretermined shaft section and the bodies (20, 21) which can be turned with respect to one another and the measuring system (19a, 19b) are built up on a torsionally elastic tube (11') as the common carrier and the tube (11') is connected with its end areas to the shaft to rotate therewith, characterized in that the torsionally elastic tube (11') is mechanically separate and exhibits a press fit which can be turned and connects the tube halves (11a, 11b) on both sides.
