Abstract

The invention provides a circle measuring frame for a large-size hydro-generator rotor and a use method thereof, in order to solve the problem of the prior art that no testing tool can be used for measuring a radius of each point on an external circle of a pole of a hydro-generator rotor at any time during an assembling process. The circle measuring frame for the large-size hydro-generator rotor comprises a spindle connecting mechanism, a counterweight shaft, a counterweight, a horizontal supporting frame and a measuring arm. If the circle measuring frame for the large-size hydro-generator rotor provided by the invention is used for measuring the assembling of the hydro-generator rotor, the radius of the external circle of each pole can be measured at any time, the circular degree and the concentricity of the external circle of each pole are checked and the central height of the each pole and the central height of a stator are kept consistent. The circle measuring frame for the large-size hydro-generator rotor has the beneficial effects that the circular degree and the concentricity of the external circle of each pole during the assembling process of the rotor are ensured, the central height of each pole is ensured and the circle measuring frame plays an important role in ensuring the safe running of a machine set. Besides, the circle measuring frame has generality and can meet the requirements of the assembling of the hydro-generator rotors in various sizes.

Description

technical field [0001] The invention relates to the assembly technology of the rotor of a large hydroelectric generator, in particular to a round measuring frame for a rotor of a large hydroelectric generator and a method for using the same. Background technique [0002] During the operation of the rotor of a large hydro-generator, the gap between the rotor and the stator is very small, only 8-40 mm, and the main shaft of the generator drives the rotor, the main shaft of the water machine, the runner, etc. at a speed of hundreds to thousands per minute. Rotate at a high speed (generally, the whole rotation weight of the unit is more than 10 tons), if the outer roundness of the rotor does not meet the requirements, the gap with the stator will be uneven, and it will cause a lot of damage during the rotation of the unit. The vibration will affect the power generation of the unit. If the height of the center of the magnetic pole is inconsistent with the height of the center of...
