An angular-position measuring device for measuring the angular position between a stationary object and an object which is rotatable with respect to the stationary object on an axis of rotation, the device comprising:
- a scanning unit for scanning a scale wherein the scanning unit is fastened on a stator of the angular-position measuring device;
- a mounting element provided between the stator and the stationary object for fastening the stator in a torsion-proof manner on the stationary object, wherein the mounting element has at least a clamping element for radial clamping between the stator of the angular-position measuring device and the stationary object, wherein an actuating element cooperates with the clamping element and is aligned in a direction parallel with the axis of rotation and is accessible and actuable in this direction for clamping.
An angular-position measuring device for measuring the angular position between a stationary object and an object which is rotatable with respect to the stationary object on an axis of rotation, the device comprising:
- a scanning unit for scanning a scale wherein the scanning unit is fastened on a stator of the angular-position measuring device;
- a mounting element provided between the stator and the stationary object for fastening the stator in a torsion-proof manner on the stationary object, wherein the mounting element has at least a clamping element for radial clamping between the stator of the angular-position measuring device and the stationary object, wherein the clamping element or an actuating element cooperating with the clamping element is aligned in a direction parallel with the axis of rotation and is accessible and actuable in this direction for clamping;
- and
- a torsion-proof, yet radially and axially resilient coupling interposed between the stator of the angular-position measuring device and the stationary object, wherein the mounting element with at least one clamping element is provided for radial clamping between the stator and the coupling.
