Abstract
The invention discloses a turbine generator rotor assembly roundness measuring device. A central rotating body is axially supported on the upper end face of a column, and radially rotates around the column. By adjusting the eccentric amount of an eccentric shaft, the central rotating body can be adjusted to be parallel to and coaxial with the axis of the column. By adjusting a top wire I, the horizontal rotating accuracy of a measuring arm around the column can be adjusted. By adjusting a top wire II, the rotating center of the measuring arm can be adjusted to be concentric with a rotor. A gauge stand can slide along a measuring rod, so that the device can accurately measure the roundness and the concentricity of measurement points of different heights and positions in a rotor assembly process. The turbine generator rotor assembly roundness measuring device provided by the invention has the advantages of simple structure, easy installation and debugging, high measuring accuracy, safe and reliable use and low cost. A universal, serialized and standardized product can be realized.
