Assembly for measuring eccentricity of squeeze film damper

The invention relates to an assembly for measuring the eccentricity of a squeeze film damper, which comprises a measuring ring and a measuring scale, four measuring holes t and four reference planes are uniformly distributed along the circumference of the measuring ring, and each reference plane corresponds to one measuring hole. The measuring ruler is composed of a main ruler, a vernier and a depth ruler. And the measuring scale is matched with the measuring ring for use and is used for measuring the shortest distance from the outer surface of the supporting frame of the extrusion oil film damper to the reference plane. According to the invention, the reference plane and the measuring hole on the measuring ring can be used for radial measurement of the depth gauge, so that the space requirement of the measurement work is reduced, and the actual operation is more convenient; the measuring hole fixes the measuring position, so that the measuring precision is improved; during measurement, the surface tidiness o
