Abstract
A thrust-sensing assembly for a bearing compartment of a gas turbine engine includes a spacer and a retaining ring. The spacer includes an outer frusto-conical portion and an inner ring. The outer frusto-conical portion includes an axial row of a plurality of slots. Each slot of the plurality of slots includes a first rounded end, a second rounded end, a first side-face, and a second side face that faces the first side-face. The retaining ring includes a plurality of axial extensions with distal ends that are in contact with the outer frusto-conical portion of the spacer.

A thrust-sensing assembly for a bearing compartment of a gas turbine engine, the thrust-sensing assembly comprising:
- a spacer comprising:
- an outer frusto-conical portion with an axial row of a plurality of slots, wherein each slot of the plurality of slots includes a first rounded end, a second rounded end, a first side-face, and a second side face, wherein the first and second side faces face each other;
- and
- an inner ring connected to the outer frusto-conical portion at a first axial end of the outer frusto-conical portion;
- a strain gauge mounted to one of the slots of the plurality of slots;
- and
- a retaining ring with a plurality of axial extensions, wherein the distal ends of the axial extensions are in contact with the outer frusto-conical portion of the spacer.
An assembly for a bearing compartment of a gas turbine engine, the assembly comprising:
- a bearing support connected to a frame of the gas turbine engine;
- a thrust-sensing assembly held in position by the bearing support, wherein the thrust-sensing assembly comprises:
- a spacer comprising:
- an outer frusto-conical portion with an axial row of a plurality of slots;
- a strain gauge mounted to one of the plurality of slots;
- and
- an inner ring connected to the outer frusto-conical portion;
- and
- a retaining ring with a plurality of axial extensions that are in contact with the outer frusto-conical portion of the spacer;
- and
- a bearing assembly disposed radially inward and in contact with the thrust sensing assembly.
