Embodiment

[0024] Embodiment: As shown in the accompanying drawings, the method for on-site processing of generator yoke laminations includes the following steps:

[0025] Step 1: Foundation installation: Remove all magnetic poles of the generator rotor to be processed to facilitate the processing of the equipment in the foundation pit, select the position to be processed of the rotor yoke 7 to be processed, and groove 7-1 on both sides of the rotor yoke 7 to be processed A certain number of foundation tensioning components 8 are installed inside, as attached figure 1 As shown, in the present embodiment, 8 pieces are evenly distributed on each side;

[0026] Step 2: Component installation: Install the base plate 2 and the adjustment block 3 on both sides of the equipment base 1 outside the generator foundation pit in advance, and integrate with the axial transmission component 4 on the equipment base 1; A tangential transmission assembly 5 is installed on the axial transmission assembly...

Abstract

The invention discloses an on-site processing method and equipment for generator magnet yoke laminations. The device mainly comprises a device foundation base, foundation bottom plates and adjusting blocks are installed on the device foundation base located on the two sides of the device and used for fixedly installing axial transmission assemblies, tangential transmission assemblies are installedon the axial transmission assemblies on the two sides, and radial transmission assemblies are installed in the middles of the tangential transmission assemblies; a plurality of basic tensioning assemblies are installed in grooves in the two sides of the to-be-machined rotor magnet yoke and used for integrally installing and fixing equipment. The beneficial effects of the invention are that the method effectively avoids the possible dangerous accidents after the dislocation of the generator rotor magnet yoke, and can achieve the high-precision restoration of the generator without the need of lifting the rotor out of the generator foundation pit; for a newly-installed generator, high-precision machining can be directly carried out on the magnet yoke on site, and the technical problem of magnet yoke machining is solved. Two V-shaped faces can be machined at the same time, and it is guaranteed that all the machined faces meet the slide precision and the surface quality of magnetic pole installation requirements after the to-be-formed groove is machined.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a method and equipment for on-site processing of generator yoke laminations. Background technique [0002] With the rapid development of hydropower equipment technology, especially the rapid development of pumped storage power stations, the rotor of the generator is also developing in the direction of high speed. However, under the action of centrifugal force, the high speed will easily lead to the dislocation of the generator yoke laminations, resulting in serious quality accidents and unnecessary losses to the enterprise. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a method and equipment for on-site processing of generator yoke laminations, which can repair the generator with high precision without lifting the rotor out of the generator foundation pit; It can also be ...
