Torque measuring device and hydraulic power measuring system

Abstract

The invention provides a torque measuring device and a hydraulic power measuring system, and relates to the technical field of aero-engine testing. The torque measuring device comprises a sleeve, a rotating shaft, a strain gauge, a signal conversion assembly and a check ring, and the sleeve comprises a first mounting plate and a second mounting plate which are distributed in parallel and a bearing rib plate fixed between the first mounting plate and the second mounting plate; a static calibration device which is connected with the sleeve through a bolt and is used for applying torque to the bearing rib plate; a strain gauge which is arranged on the bearing rib plate and is used for detecting the deformation quantity generated after the bearing rib plate bears the torque; a signal conversion assembly which is electrically connected with the strain gauge and used for converting the deformation quantity detected by the strain gauge into torque information; and a check ring which is detachably connected between the first mounting plate and the second mounting plate, wherein the check ring and the rotating shaft are coaxially arranged, and the check ring is arranged on the periphery of the force bearing rib plate in a sleeving mode. According to the torque measuring device, the torque measuring precision can be improved, and the maintenance cost is reduced.

Description

Technical field[0001]The present disclosure relates to the field of aeroeir engine testing, and in particular, there is a tangle device and a hydraulic power system.Background technique[0002]Aviation engine is the core component of the aircraft. Its performance is directly affected by the pilot and the personal safety of the people. Therefore, it is especially important to test the basic performance before the aviation engine is applied to actual production.[0003]The output power of the engine is typically used to absorb and control the power output of the engine, and the engine power output control needs to measure and control the torque of the hydraulic power meter, and thus the torque of the torque is tested. However, the existing tangled thawing apparatus has a high manufacturing cost, and the test accuracy is low.[0004]It should be noted that information disclosed in the above background technology is only used to enhance the background of the present disclosure, and therefore,...
