A friction coupling for friction locking of a shaft relative to a hub, comprises a radially deformable inner sleeve, a substantially dimensionally stable outer sleeve and at least one pressure chamber defined by at least the inner sleeve and the outer sleeve. The inner sleeve is arranged to be radially deformed, thereby producing a surface pressure on the shaft, for friction locking of the shaft relative to the hub. Measuring means integrating with the outer sleeve is arranged to measure the strain of the outer sleeve, which strain is an indication of the friction locking. The above-described friction coupling can be used, for instance, in piston assemblies and press tables. |
