FORCE MEASURING DEVICE FOR MULTI-AXIS MEASUREMENT OF ACTIVE FORCES AND MOMENTS

摘要

The invention relates to a force measuring device for the at least three-axis measurement of forces Fx, Fy and Fz and/or moments Mx, My, and Mz, comprising a first flange-like part (1), via which the forces/moments to be measured are introduced, a second flange-like part (2), via which the introduced forces/moments are picked up and dissipated, and a tube-like deformation zone (3) connecting said two parts, via which all the tensile, compressive, torsional, and shear forces acting on the first flange-like part (1) are passed on to the second flange-like part (2). At least the innner or outer surface of the tube-like deformation zone (3) serves as an application surface (5) for deformation transducers (4), and the tube-like deformation zone (3) is subdivided circumferentially into at least eight sectors S1 to S8. The force measuring device also comprises an evaluation unit for forming measured values of at least one force component. The force measuring device is distinguished by the fact that at least one deformation transducer is arranged on each individual sector S1 to S8, all the deformation transducers of a sector are each wired to one another in a common Wheatstone bridge, and each sector on the tube-like deformation zone (3) is located opposite a second sector offset by 180° about the mid-axis (7) of the deformation zone (3) and having a similar arrangement of deformation transducers.
