Description

Technical Field

[0001] This utility model relates to the field of rotor assembly technology, specifically a detachable large rotor assembly. Background Technology

[0002] Large rotor assemblies, as core components of critical power equipment such as motors, generators, and turbines, directly determine the overall equipment's efficiency, service life, and maintenance costs through their operational stability and ease of maintenance. They are widely used in high-end equipment fields such as new energy power generation, industrial manufacturing, and rail transportation. With the expansion of industrial production scale and the improvement of equipment intelligence, the market has placed increasingly stringent demands on the power density, reliability, and maintenance efficiency of large rotor assemblies. This is especially true in scenarios such as large wind turbines and heavy-duty motors, where the size and weight of rotor assemblies have increased significantly, and traditional structural designs have gradually revealed many technical defects that urgently need to be addressed.

[0003] In existing technologies, the assembly of magnets, outer frame, and magnetic poles in large rotor assemblies often adopts an integrated fixed structure. Common methods include integral casting encapsulation, dense bolt fastening, or welding fixation. While this design can meet basic usage requirements in small rotor assemblies, it has significant limitations when applied to large rotors: First, it has extremely poor disassembly and assembly flexibility. When a single magnet experiences magnetic attenuation, damage, or requires periodic maintenance, the entire rotor assembly must be disassembled, which not only consumes a lot of manpower and time but may also damage other critical components such as magnetic poles and outer frame during disassembly, further increasing maintenance costs. Second, the positioning stability of the magnets is insufficient. During long-term high-speed operation, this can lead to problems such as magnet misalignment and abnormal friction noise. In severe cases, it may even cause the magnets to fall off, directly threatening the safe operation of the equipment.

[0004] In summary, current large rotor assemblies still suffer from problems such as low disassembly and maintenance efficiency and poor magnet positioning stability in their structural design, failing to fully meet the actual needs of industrial sectors for high reliability and low operation and maintenance costs. Therefore, developing a large rotor assembly capable of rapid magnet disassembly and stable positioning has become a crucial issue that urgently needs to be addressed by those skilled in the art.

[0013] Preferably, the surface of the magnet is flush with the surface of the outer frame.

[0014] Preferably, the magnetic pole has a shaft hole at its center for mounting a rotor.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a detachable large rotor assembly, which has the following advantages: This utility model discloses a detachable large rotor assembly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Example 1: This embodiment provides a detachable large rotor assembly with the following technical features.

[0029] Please see Figure 1-6 A detachable large rotor assembly includes an outer frame 11, magnets 12 and magnetic poles 13. Both magnets 12 and magnetic poles 13 are installed inside the outer frame 11. The magnetic poles 13 are located in the radial center of the outer frame 11, and the magnets 12 are arranged around the outer periphery of the magnetic poles 13. The magnet 12 is installed inside the outer frame 11 via the snap-fit ​​connector 14.

[0030] In an optional embodiment, the inner wall of the outer frame 11 is provided with a mounting groove 111, and the snap-fit ​​member 14 is movably installed inside the mounting groove 111. A slot 121 is provided on one side of the magnet 12, and the slot 121 matches the connector 14.

[0031] It should be noted that during the entire installation process, the magnetic pole 13 must first be installed inside the outer frame 11, and then the snap-fit ​​14 must be installed inside the mounting slot 111, ensuring that the snap-fit ​​14 fits tightly against the mounting slot 111. Next, the magnet 12 is installed inside the outer frame 11, paying particular attention to aligning the slot 121 on the magnet 12 with the snap-fit ​​14 to ensure proper mating. This series of operations completes the installation process, enabling a detachable design for the large rotor assembly. This not only greatly improves the flexibility and convenience of installation but also significantly facilitates efficient maintenance and repair of the large rotor assembly in the future, ensuring the long-term stable operation of the equipment.

[0032] In an optional embodiment, the snap-fit ​​14 is a resilient notched ring structure that allows for quick attachment and detachment of the magnet 12 from the notch.

[0033] In an optional embodiment, one end of the snap-fit ​​member 14 is provided with a relief groove 141, and a connecting ring 143 is provided inside the relief groove 141. A positioning piece 142 is fixedly connected to the end of the connecting ring 143.

[0034] It should be noted that the positioning piece 142 protrudes from the center of the snap-fit ​​member 14, facilitating its placement between two adjacent sets of fan-shaped magnetic components. This allows the connecting ring 143 to rotate via the positioning piece 142 when the magnet 12 is rotated. The size of the notch in the snap-fit ​​member 14 is larger than the outermost arc length of a single magnetic component but smaller than the outermost arc length of two magnetic components. This design is particularly important when installing the magnet 12. In practice, the magnet 12 is simply and smoothly installed inside the outer frame 11 along the notch of the snap-fit ​​member 14. This greatly simplifies the installation process, making the installation of the magnet 12 extremely convenient. After installation, a slight rotation of the magnet 12 causes it to rotate via the positioning piece 142, driving the connecting ring 143 to rotate. This brings the positioning piece 142 into contact with the other end of the snap-fit ​​member 14, effectively preventing the magnet 12 from accidentally falling out of the outer frame 11 and ensuring the stability and safety of the entire device. Furthermore, when it is necessary to disassemble the magnet 12, the notch of the snap-fit ​​part 14 can also be used, making the disassembly process equally simple and efficient. This design improves the ease of installation and disassembly.

[0035] In an optional embodiment, an installation step 112 is fixedly connected inside the outer frame 11, which serves to support the magnetic pole 13.

[0036] In an optional embodiment, the magnet 12 consists of several sets of identical sector-shaped magnetic components.

[0037] It should be noted that the sector-shaped magnetic components use magnetic materials. The arrangement of multiple sector-shaped magnetic components makes the disassembly and reassembly of magnet 12 more convenient and efficient, while also increasing the central magnetic field strength. Furthermore, it significantly enhances the magnetic field strength and expands its effective range in the central region of the equipment. This not only improves the magnetic field stability of the entire device during operation but also further ensures the reliability and performance of the equipment under various working conditions, thus providing users with a more stable and durable user experience.

[0038] In an optional embodiment, a high-temperature resistant elastic buffer pad is provided between the fan-shaped magnetic components of the magnet 12 to buffer the vibration and friction between the fan-shaped magnetic components.

[0039] In an alternative embodiment, the surface of the magnet 12 is flush with the surface of the outer frame 11.

[0040] It should be noted that by aligning the surface of the magnet 12 with the surface of the outer frame 11, not only is a high degree of structural consistency ensured, but the installation of large rotor assemblies is also greatly facilitated. This design allows for smoother docking and fixing when installing large rotor assemblies, avoiding installation difficulties or errors caused by uneven surfaces. Furthermore, this flush alignment also helps improve the stability and reliability of the rotor assembly in practical applications, ensuring good performance during operation.

[0041] In an optional embodiment, the magnetic pole 13 has a shaft hole 131 at its center for mounting a rotor.

[0042] Working Principle: During installation, the magnetic pole 13 must first be installed into the internal space of the outer frame 11. Because an installation step 112 is designed inside the outer frame 11, it ensures that the magnetic pole 13 will not detach from the interior of the outer frame 11 after installation and prevents displacement during subsequent operations. Next, the snap-fit ​​connector 14 needs to be accurately installed into the mounting slot 111 inside the outer frame 11. Because the snap-fit ​​connector 14 adopts an open ring design, when installing the magnet 12, the magnet 12 can be installed into the interior of the outer frame 11 sequentially from the notch of the snap-fit ​​connector 14. During installation, it is necessary to ensure that the slot 121 around the magnet 12 is in close contact with the snap-fit ​​connector 14 to ensure a stable and reliable installation of the magnet 12. After the installation of the magnet 12 is completed, rotate the magnet 12 slightly so that the magnet 12 drives the connecting ring 143 to rotate through the positioning piece 142, so that the positioning piece 142 contacts the other end of the snap-fit ​​piece 14, thereby effectively preventing the magnet 12 from accidentally falling out of the outer frame 11.

[0043] When disassembly is required, firstly, the magnet 12 is rotated in the reverse direction, causing the connecting ring 143 to rotate into the recessed groove 141 via the positioning plate 142. This opens the notch of the snap-fit ​​component 14, allowing its individual sector-shaped magnetic components to rotate to the notch. This facilitates the smooth removal of the magnet 12 from the inside of the outer frame 11, completing the disassembly of the magnet 12. Subsequently, the snap-fit ​​component 14 and the magnetic pole 13 are removed from the inside of the outer frame 11, thus completing the disassembly process of the entire large rotor. This detachable design for the large rotor assembly not only greatly improves the flexibility and convenience of installation but also provides significant convenience for efficient maintenance and repair of the large rotor assembly in the later stages, ensuring the long-term stable operation of the equipment.

[0044] A detachable large rotor assembly, through the arrangement of the outer frame 11, magnets 12, and magnetic poles 13, enables convenient disassembly and installation of the magnets 12 and magnetic poles 13 within the outer frame 11. This design not only significantly improves the flexibility during installation but also greatly facilitates efficient and precise maintenance and repair of the large rotor assembly in the future. This design concept ensures that the equipment maintains stable and reliable performance during long-term operation, effectively extending the equipment's service life, reducing maintenance costs, and thus providing users with a more reliable and efficient user experience.

[0045] A detachable large rotor assembly is provided. A snap-fit ​​connector 14 is inserted into a mounting slot 111 inside an outer frame 11. Then, the fan-shaped magnetic components are installed one by one into the interior space of the outer frame 11 through the notches in the snap-fit ​​connector 14. By rotating the magnet 12, the magnet 12 drives the connecting ring 143 to rotate via a positioning plate 142. This positions the positioning plate 142 against the other end of the snap-fit ​​connector 14, effectively positioning the magnet 12 inside the outer frame 11. This securely fixes the magnet 12, preventing it from detaching from the outer frame 11 during use due to vibration or other external forces, thus ensuring the stability and reliability of the entire device.
