The invention relates to a measuring system for determining a force and/or a torque on a torque-transmitting shaft, wherein: the measuring system has at least three, in particular at least four, piezoelectric elements each having a preferred direction and each being arranged at different positions about a rotational axis of the shaft in a force flow transmitted via the shaft, said arrangement being such that a force of the force flow acts, in particular exclusively, on the piezoelectric elements; the preferred directions each lie parallel to or in a single plane which is intersected by the rotational axis; and the preferred directions of at least two, in particular at least three, of the piezoelectric elements are oriented neither parallel nor antiparallel to one other.

Measuring system and method for determining a force and/or a torque on a torque-transmitting shaft

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.
