FIELD: machine building.
SUBSTANCE: turbomachine shaft destruction detection device includes the following: a shaft containing an inlet end and an outlet end, a bar containing an inlet end and an outlet end and located inside in and coaxially to the shaft; at that, outlet end of the bar is rigidly fixed on the shaft outlet end, and inlet end of the bar can be freely rotated in relation to the inlet end of the shaft, and a sensor provided with possibility of detecting the difference of rotation mode between inlet end of the bar and inlet end of the shaft.
EFFECT: simplifying the design of the shaft destruction detection device and reducing its weight.
