Abstract
A device for measuring axial load on a thrust bearing in an engine having an shaft inside a fixed structure comprises: stability platform in contact with the fixed structure and prevented from motion in an axial direction; at least one load tab adjacent to and supported by the stability platform, the at least one load tab oriented perpendicularly to the axial direction, each load tab having a free end opposite the end supported by the stability platform, the free end adjacent the shaft; and deflection sensor attached to the at least one load tab and responsive to the axial load, wherein the axial load is applied to the free end of the at least one load tab. An offset body may be attached between the at least one load tab and the stabilizing body, and plurality of load tabs may be arranged symmetrically on the stability platform.
