Abstract
The axial thrust exerted on a rotating shaft, such as the shaft of a turbomachine rotor, is measured by a device comprising a resilient washer sandwiched between two flange members disposed around the shaft so that the axial thrust will cause axial compression of the washer between the two flange members, and displacement-measurement probes secured to a fixed structure for measuring the displacements of the flange members so that the axial thrust can be determined from the difference between the displacements and corresponding to the change in thickness of the resilient washer.
