Device for detecting surface flatness of aero-engine flywheel

Abstract

The invention relates to the technical field of aero-engine flywheels, and discloses a device for detecting surface flatness of an aero-engine flywheel. The device comprises a base, annular teeth arearranged on a turntable, a first magnet is connected to the interior of a positioning block, a coil is arranged in the middle of the turntable, and a permanent magnet is connected to the inner side ofa supporting block. Second magnets are connected to the side walls of the push rods, and a rectangular tooth row is arranged on the left portion of the rectangular rod. The annular teeth are meshed with the rectangular tooth row on the rectangular rod, the rectangular rod drives the sliding rod to move leftwards, and the sliding rod drives the detection device to slide on the flywheel through theswing rod; when the detection device reaches the center of the flywheel, the annular teeth are separated from the rectangular tooth row on the rectangular rod, due to flywheel rotation detection, repeated detection of the detection device is avoided, meanwhile, due to the selection proportion of the annular teeth, the first rotating shaft rotates by one circle, the detection device moves by the length of the detection device, and therefore comprehensive detection of the flywheel is achieved.

Description

technical field [0001] The invention relates to the technical field of aero-engine flywheels, in particular to a detection device for the surface smoothness of an aero-engine flywheel. Background technique [0002] In a narrow sense, aviation refers to the navigation activities of manned or unmanned aircraft in the atmosphere. In a broad sense, the term aviation also refers to the science necessary for aviation activities, and also refers to various technologies involved in the research and development of aircraft. . With the development of the aerospace industry, not only can I quickly reach the distance, see the distant scenery, the people I miss, and the diversified development of the world, but also let us see the vastness of the universe. Aircraft engines are equipped with flywheels. A flywheel is a mechanical device used to store rotational kinetic energy during rotational motion. The flywheel tends to resist changes in rotational speed. When the power source has a va...
