TLDR
A rotor for a gas turbine engine includes a turbine wheel with a centerbore there-through, a main shaft projecting through the center-bore, a turbular stub shaft surrounding the main shaft at a turbine end of the latter and being rigidly connected thereto so that the stub shaft defines a radially spaced reverse flange on the main- shaft, a tubular reference shaft around the primary shaft having an output end rigidly attached to an output-end of the main rotor, and a turbine-end rotatably journaled on an inside surface of the stub
Abstract
A rotor for a gas turbine engine includes a turbine wheel with a centerbore therethrough, a main shaft projecting through the centerbore, a turbular stub shaft surrounding the main shaft at a turbine end of the latter and being rigidly connected thereto so that the stub shaft defines a radially spaced reverse flange on the main shaft, a tubular reference shaft around the main shaft having an output end rigidly connected to an output end of the main shaft and a turbine end rotatably journaled on an inside surface of the stub shaft, a plurality of axial slots in the stub shaft, a plurality of pole supports projecting radially from the reference shaft turbine end through the stub shaft slots, a plurality of first pole pieces on the pole supports, a plurality of second pole pieces on the stub shaft between the first pole pieces, and a stationary pick-up operative to develop an electrical signal proportional to the spacing between the pole pieces while the rotor rotates which spacing is proportional to rotor torque.

Expanded range monopole torque measuring system

Abstract: A torque measurement system for measuring shaft torque has two toothed wheels mounted in spaced apart relationship. Each of the wheels has a plurality of axially extending spaced teeth along its periphery extending into spaces between the teeth of the other, forming an interlaced array of teeth having tooth spacing interstices therebetween. A discontinuity is provided in the tooth pattern at at least one location around the periphery of the two wheels to serve as an index marker. A single detector such as a variable relunctance sensor is mounted proximate the wheels to provide output signals representative of circumferential widths of tooth spacing interstices and also representative of the index marker. The widths of the interstices change upon shaft torque deflection, and signals from the sensor are processed to produce a DC signal proportional to torque. The two wheels can be offset in a noload condition so that adjacent tooth spacing interstices are approximately equal in a torque deflection range of interest.
