Abstract
An assembly is provided for a turbine engine. This turbine engine assembly includes a rotating assembly and a sensor. The rotating assembly is configured to rotate about an axis. The rotating assembly includes an engine shaft and a phonic wheel threaded onto the engine shaft. The phonic wheel includes a lubricant scoop. The sensor is configured to measure fluctuations in a magnetic field induced by the phonic wheel during rotation of the rotating assembly about the axis.
Claims17
An assembly for a turbine engine, comprising:
- a rotating assembly configured to rotate about an axis, the rotating assembly including an engine shaft and a phonic wheel threaded onto the engine shaft, the phonic wheel comprising a lubricant scoop;
- and
- a sensor configured to measure fluctuations in a magnetic field induced by the phonic wheel during rotation of the rotating assembly about the axis;
- wherein the lubricant scoop comprises a gutter projecting radially in an outward direction into the phonic wheel, the gutter projects axially into the phonic wheel, and the gutter extends circumferentially about the axis within the phonic wheel;
- and
- wherein the engine shaft comprises a plurality of passages arranged circumferentially about the axis, and each of the plurality of passages extends axially into the engine shaft from the gutter.
An assembly for a turbine engine, comprising:
- a rotating assembly configured to rotate about an axis, the rotating assembly including an engine shaft and a phonic wheel threaded onto the engine shaft, the phonic wheel comprising a lubricant scoop;
- and
- a sensor configured to measure fluctuations in a magnetic field induced by the phonic wheel during rotation of the rotating assembly about the axis;
- wherein the engine shaft further comprises a shoulder;
- wherein the rotating assembly further comprises an engine component mounted on the engine shaft and abutted axially against the shoulder;
- wherein the phonic wheel circumscribes and is threaded onto the shoulder;
- and
- wherein the engine component comprises an inner race of a rolling element bearing.
An assembly for a turbine engine, comprising:
- a rotating assembly configured to rotate about an axis, the rotating assembly including an engine shaft and a phonic wheel threaded onto the engine shaft, the phonic wheel comprising a lubricant scoop;
- and
- a sensor configured to measure fluctuations in a magnetic field induced by the phonic wheel during rotation of the rotating assembly about the axis;
- wherein the rotating assembly further comprises an engine component mounted on the engine shaft;
- and
- wherein the phonic wheel further comprises an anti-rotation tab projecting axially partially into a recess in the engine component.
An assembly for a turbine engine, comprising:
- a rotating assembly configured to rotate about an axis, the rotating assembly including an engine shaft and a phonic wheel threaded onto the engine shaft at a threaded interface, the phonic wheel abutted axially against the engine shaft at a location discrete from the threaded interface, and rotating assembly further comprising an engine component mounted on the engine shaft;
- and
- a sensor configured to measure fluctuations in a magnetic field induced by the phonic wheel during rotation of the rotating assembly about the axis, the phonic wheel rotationally fixed to the engine component by an anti-rotation feature.
