TURBOMACHINE, WHICH CONTAINS THE MEANS OF SPEED MEASUREMENT AND TORQUE OF THE TURBOMACHINE SHAFT, AND THE METHOD OF MONITORING THE MENTIONED SHAFT Russian patent published in 2018 - IPC F01D21/00 F02K3/02 G01M15/14 

FIELD: machine building.

SUBSTANCE: turbomachine for the aircraft, comprising at least one axle shaft (2), which is mounted to be rotating in the turbomachine body; where the turbomachine comprises the reference annular part (10), which comprises short (11) and long (12) longitudinal reference teeth, the first means for detecting the passage of short (11) and long (12) reference teeth for measuring the speed of the shaft (2) of the turbomachine (1) around its axis (X), the circumferential annular part (20), which contains the longitudinal goniometric teeth (21) and the second means for detecting the passage of the long (12) reference teeth and the goniometric teeth (21) for measuring the torque of the shaft (2) of the turbomachine. Long reference teeth allow, on the one hand, to measure the speed in the first transverse plane, and, on the other hand, to measure the torque in the second transverse plane. Reference part and the goniometric detail of the turbomachine allow, therefore, to measure simultaneously two parameters of the shaft.

EFFECT: number of parts, which are used in order to perform the measurements, is thus less than that of the prior art, this restricts the mass and overall dimensions of the turbomachine, and in addition, it is easier to carry out installation and maintenance than in case of the prior art.
