Claims (4)

1. Устройство измерения осевой тяги, создаваемой между вращающимся валом вокруг оси 2, валом 1 и неподвижной конструкцией, при этом, осевая тяга (4) создается между вращающимся валом (1) и неподвижной конструкцией (3) с помощью, по меньшей мере, одного подшипника (5), выполненного с вращающимся упором (10), который поддерживает осевую тягу (4), причем вращающийся упор (10) удерживается устройством осевого соединения (12), воздействующим тягой на этот вращающийся упор (10) и воспроизводящим осевую тягу (4), отличающееся тем, что вращающийся упор (10) выполнен с возможностью перемещения в осевом направлении по вращающемуся валу (1), причем имеются два фланца (14, 16), разделенные упругой шайбой (15) и расположенные между устройством осевого соединения (12) и вращающимся упором (10), и эти фланцы (14, 16) имеют соответственно измерительные боковые стороны (14а, 16а), сориентированные в одном направлении, при этом, упругая шайба (15) имеет боковые стороны (15а, 156); два зонда (17, 18) измерения перемещения, соединенные с неподвижной конструкцией (3), и расположенные каждый напротив измерительной боковой стороны (14а, 16а), а также устройство для определения разницы измерений этих зондов (17, 18) и для определения соответствующей осевой тяги, для того, чтобы осуществить осевую деформацию сжатия упругой шайбы (15) на вращающемся валу (1) и вывести из измерения изменений положения боковых сторон (15а, 156) этой упругой шайбы (15), начиная от неподвижной конструкции (3), величину P этой осевой тяги (4).1. A device for measuring axial thrust generated between a rotating shaft around axis 2, shaft 1 and a fixed structure, while an axial thrust (4) is created between the rotating shaft (1) and the fixed structure (3) using at least one bearing (5), made with a rotating stop (10), which supports axial thrust (4), and the rotating stop (10) is held by an axial joint device (12), which acts on the rotating stop (10) and reproduces axial thrust (4) ), characterized in that the rotating stop (10) is made the ability to move in the axial direction along the rotating shaft (1), and there are two flanges (14, 16), separated by an elastic washer (15) and located between the axial connection device (12) and the rotating stop (10), and these flanges (14, 16) respectively have measuring sides (14a, 16a) oriented in one direction, while the elastic washer (15) has sides (15a, 156); two probes (17, 18) for measuring displacement connected to a fixed structure (3) and each located opposite the measuring side (14a, 16a), as well as a device for determining the difference in measurements of these probes (17, 18) and for determining the corresponding axial thrust, in order to effect axial compression deformation of the elastic washer (15) on the rotating shaft (1) and deduce from the measurement of changes in the position of the lateral sides (15a, 156) of this elastic washer (15), starting from the fixed structure (3), the value P of this axial thrust (4). 2. Устройство по п. 1, отличающееся тем, что упругая шайба (15) и фланцы (14, 16) расположены на валу (1) на выходе (13) из подшипника (5) с возможностью использования пространства, окружающего вал (1) в этом месте. 2.
