Abstract

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.
