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, a phonic wheel and a lubricant scoop. The phonic wheel is mounted onto the engine shaft. The phonic wheel includes an outer surface and a plurality of apertures arranged circumferentially about the axis. Each of the apertures projects at least partially radially into the phonic wheel from the outer surface. The lubricant scoop is radially outboard of and axially overlaps the outer surface. 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.

An assembly for a turbine engine, comprising:
- a rotating assembly configured to rotate about an axis, the rotating assembly including an engine shaft, a phonic wheel and a lubricant scoop;
- the phonic wheel mounted onto the engine shaft, the phonic wheel including an outer surface and a plurality of apertures arranged circumferentially about the axis, and each of the plurality of apertures projecting at least partially radially into the phonic wheel from the outer surface;
- and
- the lubricant scoop radially outboard of and axially overlapping the outer surface;
- 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.
An assembly for a turbine engine, comprising:
- a rotating assembly configured to rotate about an axis, the rotating assembly including an engine shaft, a phonic wheel and a lubricant scoop integrated into the phonic wheel;
- the phonic wheel mounted onto the engine shaft, the phonic wheel including a plurality of apertures and an annular channel fluidly coupled with the plurality of apertures;
- the plurality of apertures arranged circumferentially about the axis and forming the lubricant scoop and a castellated region of the phonic wheel, each of the plurality of apertures extending radially through the phonic wheel to the annular channel;
- and
- the annular channel disposed at a radial inner side of the phonic wheel;
- and
- a sensor configured to measure fluctuations in a magnetic field induced by the castellated region of the phonic wheel during rotation of the rotating assembly about the axis.
