Method for measuring torque of e.g. low pressure shaft of two shaft type aircraft engine for military applications, involves recognizing and evaluating torque signals for load quantity of signal sensors distributed around periphery of shaft

摘要

The method involves producing torque signals for a metallic rotary shaft (3) by a magnetic coding (5) of the shaft, where the magnetic coding has two different signal types. The torque signals are recognized and evaluated for quantity of a load of two housing-firm signal sensors that are symmetrically distributed around a periphery of the shaft. A magnetic structure i.e. axial stripe pattern, of the signal types is provided for measuring the torque signals of the shaft to produce a trigger signal during fully integral rotation of the shaft for detection of the fully integral rotations. An independent claim is also included for a device for executing a method for measuring torque of a metallic rotary shaft e.g. low pressure shaft, high pressure shaft and gear shaft, of a turbo-engine i.e. aircraft engine.
