Abstract

The invention relates to an adjustment mechanism of an aero-engine air belt rotation tester, which includes a main support frame, a slider, a pull rod, a locking cylinder, and an inclined iron. Threads in opposite directions, the pull rod is installed between the two hinge ears, the piston of the locking cylinder is equipped with a pull rod, the pull rod is connected to the hinge ear through the thread, and the hinge ear is connected to the shaft sleeve of the air gun head. The provided support arm is hinged, and the positions of the two oblique irons are at the two ends of the bottom of the main supporting frame along the moving direction of the slider, and an inclined surface matching the two oblique irons is arranged below the main supporting frame. The present invention can realize the positions and rotation angles of the air-supply gun head in various directions through the setting of the tie rods, hinge ears and inclined irons, and achieves the purpose of ensuring that the air belt rotation test of the aero-engine can be carried out continuously. Through practical application, the effect is good .

Description

technical field [0001] The invention relates to an adjustment mechanism of an aero-engine air belt rotation tester. Background technique [0002] Before the aeroengine is delivered for use, a series of ground tests are carried out to ensure that the product meets the flight requirements. During the test, the aero-engine needs to be started in order to collect various working parameters. The starting method of some aero-engines during work is pyrotechnic starting, which is a one-time starting method. Although the ground test can be carried out by adopting the pyrotechnic starting method, the production cost will be greatly increased, and the safety of the test run will be increased while wasting financial resources. Under normal circumstances, it can be started with an air-rotating device, that is, high-pressure air is introduced to the position of the engine starting blade, and the blade is blown to drive the engine to start. After the engine works normally, the whole bel...
