Abstract:
An apparatus for measuring eccentricity between two circular structures attached together comprising:a vernier measuring device comprises a main scale and a vernier scale, said vernier scale for sliding in a slot opening provided in said main scale,a mounting block having a V-shaped top surface for receiving said main scale of the vernier measuring device with its longitudinal axis perpendicular to said mounting block and its center line intersects the bottom of the ""V"" in said V-shaped top surface such that a first zero setting on said main scale coincides with a center of a first circular structure, anda second circular structure attached to said first circular structure and having its radial axis perpendicular to said mounting block such that a second zero setting on said vernier scale coincides with a center of said second circular structure, wherein an eccentricity between said first circular structure and said second circular structure is determined by a distance between said first zero setting on said main scale and said second zero setting on said vernier scale.
