The invention discloses a shaft coupling fatigue testing device, which comprises a workbench, the upper surface of the workbench is connected with a test motor, the output shaft of the test motor is connected with a positioning shaft through a reduction box, and the positioning shaft is connected with a A positioning flange coaxial with the positioning shaft, a mounting box is provided on the upper surface of the workbench, a connecting shaft coaxial with the positioning flange is rotatably connected to the mounting box, and a connecting flange is fixed on the connecting shaft , the installation box is provided with a limit assembly to prevent the rotation of the connecting shaft, the two ends of the coupling to be tested are fixed on the positioning flange and the connecting flange, and the upper surface of the workbench is provided with a drive The installation box is a drive mechanism that moves in a direction perpendicular to the axis of the coupling. It acts on the driving mechanism to make the installation box move in a direction perpendicular to the axis of the coupling, which is convenient for testing the radial force of the coupling.
Description
technical field [0001] The invention relates to the technical field of anti-fatigue testing, in particular to a coupling fatigue testing equipment. Background technique [0002] A wind turbine is a device that converts electrical energy into mechanical energy. The mechanical work drives the rotor to rotate, and finally outputs an electrical device that generates alternating current. Wind turbines are generally composed of components such as wind rotors, generator sets, steering devices, towers, speed limit safety mechanisms, and energy storage devices. The wind wheel drives the generator set to work under the blowing of the wind, thereby generating electric energy. The wind rotor is mainly connected with the coupling of the generator set, and the strength and stability of the coupling also determine the efficiency and service life of the wind turbine. In order to ensure the quality of the coupling, it is often necessary to perform fatigue tests on the coupling during produ...
