Description

Integrated rotating shaft inspection and measurement device Technical Field The invention belongs to the technical field of aircraft engine fuel feed pumps, and particularly relates to an integrated rotating shaft inspection and measurement device. Background The method comprises the steps of carrying out regular detection in the operation process of an aeroengine system, on one hand, detecting the rotating speed of a rotating shaft of the aeroengine system in real time when the aeroengine system is in operation, detecting the rotating speed of the rotating shaft generally through a tone wheel in the prior art, enabling the tone wheel (1) to rotate along with the rotating shaft (4), cutting a magnetic field generated around a sensor (7) through gear teeth arranged on the peripheral surface of the tone wheel (1), enabling rotating speed information of the rotating shaft (4) to be converted into sound signals, and transmitting the sound signals to a user through the sensor (7), and on the other hand, when the aeroengine system stops in operation, detecting the internal mechanical structure or an assembly gap of the aeroengine system, wherein the detecting mode is to apply a rotating moment to the rotating shaft mainly through a manual tool by a user, and judging whether the internal mechanical structure or the assembly gap of the aeroengine system needs maintenance or not through sound emitted by the user in the slow rotating process of the rotating shaft. In the prior art, the patent document with the authority bulletin number of CN113959722B discloses a torque-pitch-phase angle-rotating speed integrated measuring device based on a sound wheel, which comprises a torsion spring shaft (10), a sound wheel component, a magnetic induction probe (11), a signal processing module (12) and a data display module (13). The sound wheel component is arranged on the torsion spring shaft with a non-circular section, one end face of the sound wheel component is fixedly connected with the beta feedback rod of the propeller, and the sound wheel component can rotate and axially slide on the torsion spring shaft. The signal processing module (12) is capable of determining the torque, pitch, phase angle and rotational speed of the propeller, respectively, based on the long delay, short delay, specific interval and expected delay of the response signal of the magnetic induction probe (11). By adopting the technical proposal of the patent, U-shaped torque teeth and splayed sign teeth are adopted, the torsion angle of the torque teeth reflects the torque, the pitch of the two sign teeth reflects the pitch, and the two pairs of symmetrical teeth have the functions of complementarily correcting magneto-electric detection signals and reducing unbalance, so that the two pairs of symmetrical teeth have double sensitivity and good rotating shaft dynamic balance characteristics. However, in the prior art, detection and research on various performance parameters of an aeroengine system are mostly focused on obtaining corresponding performance parameters through advanced electronic technology, and only when the aeroengine system is running, the corresponding performance parameters can be detected, and when the aeroengine system is stopped, the mechanical structure or assembly clearance of the aeroengine system needs to be checked, and because in the prior art, a manual tool is usually connected with a rotating shaft in a meshed manner by using a gear mechanism, the gear mechanism has a large appearance volume, and is unfavorable for operating in a narrow space.
