Abstract

The invention discloses a torque calibration device for a long shaft assembly, and a torque calibration method using the device. The torque calibration device for a long shaft assembly includes a mounting bracket, and also includes a first angle measuring instrument, a second angle measuring instrument and a graphical analysis and display system, wherein the mounting bracket is used for mounting a long shaft assembly; a torque loading member is arranged on the mounting bracket; the torque loading member is connected with a loading end of the long shaft assembly so as to successively load the torque for the long shaft assembly or successively unload the loaded torque; the first angle measuring instrument is arranged on the loading end of a transmission shaft; the second angle measuring instrument is arranged at the second end of a basic shaft; the graphical analysis and display system is used for recording, analyzing and displaying the corresponding relationship between the torque and the angular displacement; and both the first angle measuring instrument and the second angle measuring instrument are connected with the graphical analysis and display system. The torque calibration device for a long shaft assembly enables loading or unloading effect to approach electrodeless loading or unloading, and can eliminate the influence of the gap between the long shaft assembly and the torque calibration device and improve the accuracy and maneuverability of the torque testing result.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a long-shaft component torque calibration device. In addition, the invention also relates to a method for calibrating the torque of the long shaft assembly using the device. Background technique [0002] The design of the long shaft assembly of the turboshaft engine requires that under the loading and unloading test conditions, according to the change of the torque value, the angular displacement Ψ1 and Ψ2 of the front and rear ends are recorded to form a torque-angle relationship curve. After the test process is completed, the linearity of the end base is formed. It can only be installed and used when the end-base linearity is ≤3%. The existing torque calibration device has low accuracy and low operability when calibrating torque. Contents of the invention [0003] The invention provides a long-axis component torque calibration device and a torque calibration method using the dev...
