Estimating the term…
The invention relates to a measuring device for determining force and/or torque on a torque-transmitting shaft which is supported by a bearing device, in particular a machine, the output and/or input shaft of which is formed by the torque-transmitting shaft. The measuring device has at least two, preferably three or four, piezoelectric elements and a fixing device, wherein the fixing device supports the piezoelements and is designed in such a way that a force, in particular shear force, can be measured between the bearing device and a supporting device for supporting the bearing device by means of the piezoelements.
A measuring device for determining a torque on a torque-transmitting shaft which is supported by a bearing apparatus, an output shaft or an input shaft of the bearing apparatus being formed by the torque-transmitting shaft, the measuring device comprising:
A measuring arrangement for determining a torque on a torque-transmitting shaft, comprising:
A method for determining a torque applied to a shaft, wherein the torque is determined by measuring reactive forces of a bearing of a bearing apparatus of the shaft on the bearing apparatus via at least two piezoelements, wherein the reactive forces are measured as shear forces on the at least two piezoelements, and wherein a fixing device supports the at least two piezoelements, and wherein the fixing device and the at least two piezoelements are, for determining the torque, configured to measure the shear forces between the bearing apparatus and a supporting apparatus for supporting the bearing apparatus.
