Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to an assembled generator rotor core. Background Art

[0002] As we all know, a generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy.

[0003] The rotor of a traditional generator is integrated, with several groups stacked together. During assembly, it is easy for the rotors to be misaligned. If the rotor is partially damaged, the rotor cannot be used, which easily leads to a waste of resources. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4, an assembled generator rotor core, comprising a base ring 1, a fin 2 and a support assembly, an auxiliary ring 3 is arranged below the base ring 1, and several groups of the support assemblies are arranged around the auxiliary ring 3, the support assembly comprises a bottom plate 4 and a limit plate 5, the bottom plate 4 is connected to the auxiliary ring 3, the limit plate 5 is arranged at the center above the bottom plate 4, the limit plate 5 is T-shaped, a slide groove matched with the limit plate 5 is arranged at the center below the fin 2, a first positioning hole is arranged at one end of the fin 2 close to the base ring 1, a second positioning hole is arranged on the auxiliary ring 3, the first positioning hole is matched with the first positioning hole, and the fin 2 and the support assembly are arranged as several groups evenly arranged.

[0023] An auxiliary ring 3 is provided on the base ring 1 for supporting the bottom plate 4. A limit plate 5 is also provided on the bottom plate 4. The fin 2 is slidably connected with the limit plate 5. When the first positioning hole is aligned with the second positioning hole, they are fixed by plugging and connecting with a pin. The base ring 1 is also plugged through the center axis so that several groups of assembled rotor cores are stacked together. The limit plate 5 is T-shaped to prevent the fin 2 from sliding up and down. At the same time, the limit plate 5 can also increase the strength of the bottom plate 4. The inner wall of the base ring 1 is also provided with two groups of symmetrically arranged arc grooves to ensure that the base ring 1 rotates synchronously with the center axis.

[0024] During actual use, the auxiliary ring 3 is also provided with an auxiliary plate 6 for limiting the fin 2, and elastic friction blocks 7 for fastening the side walls of the fin 2 are embedded on both sides of the auxiliary plate 6. As the fin 2 slides in, the elastic friction blocks 7 of the auxiliary plate 6 clamp the fin 2 from both sides to prevent the fin 2 from slipping off the supporting assembly before it is fixed by the pin rod.

[0025] In this embodiment, the elastic friction block 7 is made of vulcanized rubber, which has good corrosion resistance and stability.

[0026] In actual use, it is also necessary to ensure the heat dissipation effect of the equipment. The fins 2 are also provided with symmetrically arranged heat dissipation holes, and the heat dissipation holes are arranged on both sides of the limit plate 5. Since several groups of rotor cores are fixed by non-cylindrical pins, it is convenient to ensure that the heat dissipation holes are aligned to ensure the overall heat dissipation effect.
