Problems solved by technology

This method requires earphones to listen to the current sound when the micrometer is in contact with the piano wire 6. The piano wire 6 may vibrate during the measurement process, and the wiring work of the earphones and the piano wire 6 is relatively cumbersome, and it is necessary to use an inner diameter micrometer to measure more. Group data, so the workload and error are relatively large

Abstract

The invention provides a measuring device for the absolute radius of a hydro-generator rotor. The device comprises a rotor (1), a roundness measurement rack center pillar (2), an inside micrometer (3), an I-shaped straight edge (4), and a magnetic pole (5). The roundness measurement rack center pillar (2) is arranged at the right center of the rotor (1); the center point of the roundness measurement rack center pillar (2) coincides with the center point of the rotor (1); the outer edge of the rotor (1) is provided with the magnetic pole (5); the outer side of the magnetic pole (5) is provided with the I-shaped straight edge (4); the two ends of the I-shaped straight edge (4) extend out of the upper vertex and the lower vertex of the magnetic pole (5). The device solves the problem of large workload and error in the prior art where piano wires are used and reduces the workload.

Description

technical field [0001] The invention relates to the technical field of the absolute radius of a water turbine rotor, and more specifically relates to a device and a method for measuring the absolute radius of a water turbine generator rotor. Background technique [0002] The rotor of the hydroelectric generator is an approximate cylinder, and its outer edge is the rotor yoke and magnetic poles. When the unit is overhauled, in order to keep the gap between the stator and the rotor within the specified range and reduce the vibration of the unit during operation, it is necessary to The roundness of the rotor is adjusted, and then the absolute radius of the rotor needs to be measured, that is, the distance between each measuring point on a specified magnetic pole or yoke and the center line of the rotor (the measurement accuracy is 0.01mm, and the surface processing accuracy of the flat ruler is 2.5μm). At present, the absolute radius of the hydro-generator rotor is generally me...
