ABSTRACT:
A clamping force relates to a clamping-force transducer for rotating clamping devices which has at least two opposite pressure pieces adapted to be placed on the clamping elements of the corresponding clamping device and arranged in a support member, at least one of which pressure pieces acts on a force transducer the measurement values of which are taken from the rotating clamping-force transducer housing via a stationary transfer housing. To adapt the clamping-force transducer simply to clamping devices having a different number of clamping elements and to different clamping diameters without the rigidity of the clamping-force transducer being changed thereby, the pressure pieces are arranged replaceably but fixed on the arms of a multi-arm measurement member, at least one arm of the measurement member being developed as the force transducer. The measurement member preferably has a star shape with six arms, each of which has a connection for a pressure piece. In order to determine the corresponding speed of rotation at the same time as the clamping force, a pulse transmitter for a pulse receiver arranged on the fixed transfer housing is arranged on the rotating clamping-force transducer housing.
