Description
Technical Field
[0001] This utility model relates to the field of stator and rotor technology, specifically a quick-assembly stator and rotor assembly. Background Technology
[0002] In existing stator and rotor assemblies, traditional assembly methods typically involve fastening and securing multiple components, making the assembly process complex and time-consuming. Furthermore, stator and rotor assemblies may fail due to overheating or wear during long-term operation, leading to increased downtime for maintenance. Therefore, improving the assembly efficiency of stator and rotor assemblies, reducing maintenance costs, and enhancing their durability have become urgent problems to be solved.
[0003] Currently, most stator and rotor assemblies have relatively complex structural designs, and the connections between components are usually made by welding or fixing bolts. The disassembly and replacement process is cumbersome, which not only increases the difficulty of operation but also extends the maintenance time. In addition, due to the harsh working environment of stator and rotor assemblies, especially under high-speed operation and high temperature and pressure conditions, wear and heat accumulation of components often affect their performance and lifespan.
[0004] While existing quick-assembly designs improve ease of assembly and disassembly, most focus only on improving individual components and fail to achieve overall optimization of the stator and rotor assembly, particularly in terms of improving assembly stability and electromagnetic conversion efficiency. Therefore, the market urgently needs a stator and rotor assembly that is simple in structure, easy to assemble and disassemble, highly stable, and can effectively improve electromagnetic conversion efficiency.
[0005] To address the aforementioned issues, this invention proposes a quick-assembly stator-rotor assembly. Through innovative structural design, it enhances assembly efficiency and stability while maintaining high-efficiency electromagnetic conversion, and simplifies maintenance procedures, providing a more reliable and efficient solution for industrial equipment. Utility Model Content
[0006] This invention provides a quick-assembly stator and rotor assembly, designed to improve assembly efficiency and maintenance convenience through a structural design that facilitates disassembly and assembly. The assembly features a well-fitting structure between the stator and rotor, effectively enhancing working efficiency while ensuring stability and reliability.
[0007] The technical solution of this utility model includes the following:
[0008] Structural design of the stator and rotor assembly: The stator and rotor assembly of this utility model consists of three parts: a rotor shaft, a stator assembly, and a retaining ring. A permanent magnet block is installed at the center of the rotor shaft. The stator assembly includes a retaining ring seat, a magnetic yoke block, and a coil assembly. The retaining ring is fixed to the upper and lower ends of the retaining ring seat by tension screws.
[0009] The cooperation between the rotor shaft and the permanent magnet blocks: Several permanent magnet blocks are embedded and installed on the upper surface of the rotor shaft. These permanent magnet blocks are distributed along the axial direction of the rotor shaft and are arranged opposite to the magnetic yoke blocks in the stator assembly, forming an electromagnetic induction effect. The reasonable arrangement of the permanent magnet blocks ensures efficient energy conversion between the rotor shaft and the stator assembly.
[0010] Stator assembly structure: The stator assembly consists of a collar seat, a yoke block, and coil assemblies. The collar seat has slots on its surface that fit the surface of the yoke block, allowing the yoke block to be detachably connected to the collar seat via these slots. The coil assemblies are fitted one-to-one onto the surface of the yoke block, forming an electromagnetic induction with the permanent magnet on the rotor shaft, ensuring a stable current output during system operation.
[0011] The functions of the retaining ring and tensioning screws: The retaining ring, along with several tensioning screws, secures the stator assembly together, ensuring its structural stability. The detachable design of the retaining ring allows for quick disassembly of the stator and rotor assembly when maintenance or replacement is needed, facilitating operation and maintenance. The tensioning screws enhance the assembly's robustness and are fixed to the outer circumference of the retaining ring seat via positioning slots.
[0012] Material Selection and Durability: In this invention, the sheath ring is made of composite ceramic material, which has good high-temperature resistance and corrosion resistance, and can maintain the long-term stability of the component in harsh working environments. Furthermore, the magnetic yoke block is composed of silicon steel sheets, possessing excellent magnetic permeability, effectively improving the electromagnetic conversion efficiency of the system.
[0013] Easy-to-assemble / disassemble design: This utility model features a quick-assembly / disassembly mechanism. A stable connection between the rotor shaft and stator assembly is achieved through the locking and fixing of the tension screw, while the disassembly and assembly of each component are extremely convenient. This design significantly improves production, installation, and maintenance efficiency, and reduces the complexity of manual operation.
[0014] Through the above structural design, the quick-installation stator and rotor assembly of this invention exhibits excellent performance in mechanical, electromagnetic conversion, and heat conduction. The assembly's convenient assembly and disassembly capabilities make it suitable for applications requiring frequent replacement and maintenance, demonstrating high practicality and promising market prospects.
[0015] The beneficial effects achieved by this utility model are as follows:
[0016] 1. This utility model adopts a quick-installation design, making the assembly and disassembly of the stator and rotor assemblies simpler and faster. Through the fixing action of the tension screw, the connection between the stator assembly and the rotor shaft is more stable, while also allowing for quick disassembly, greatly improving the efficiency of assembly and maintenance.
[0017] 2. In this invention, the cooperation between the sheath ring and the tensioning screw securely locks the various parts of the stator and rotor assembly together, preventing loosening or detachment during operation. This design ensures that the assembly maintains good working condition even under high-frequency operating conditions, thereby improving the overall stability of the system.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0026] The following is in conjunction with the appendix Figures 1-4 This invention describes a quick-assembly stator and rotor assembly provided by some embodiments of the present invention. Example 1
[0027] like Figure 1 As shown, the overall structure of the quick-assembly stator-rotor assembly includes a rotor shaft 100, a stator assembly 200, and a retaining ring 300. In this embodiment, the rotor shaft 100 is made of steel and has sufficient strength to bear the magnetic field generated by the permanent magnet blocks 110 on the rotor.
[0028] Structure of rotor shaft 100 and permanent magnet blocks 110: The rotor shaft 100 is located at the center of the stator-rotor assembly, and several permanent magnet blocks 110 are embedded and installed on the surface of the rotor shaft 100. The permanent magnet blocks 110 are arranged in a ring and are arranged opposite to the magnetic yoke block 220 to form a stable magnetic field. During assembly, the permanent magnet blocks 110 are fixed to the rotor shaft 100 by a suitable mechanical connection method, ensuring their precise position relative to the rotor shaft 100.
[0029] The stator assembly 200 comprises a collar seat 210, a yoke block 220, and a coil assembly 230. The collar seat 210 is made of metal and possesses a certain strength. A slot adapted to the surface of the yoke block 220 is formed on the upper surface of the collar seat 210 for insertion and fixation of the yoke block 220. The yoke block 220 is formed by assembling several silicon steel sheets to provide efficient magnetic field flux. One side of the yoke block 220 is coated with a thermally conductive grease layer that mates with the inner side of the collar seat 210 to improve heat conduction efficiency and reduce heat generated during operation.
[0030] Coil groups 230 are fitted one-to-one onto the surface of magnetic yoke blocks 220. Each coil group 230 is made of insulated wire. During the winding process, it is ensured that the coil group 230 and the magnetic yoke block 220 are in close contact to ensure a high-efficiency electromagnetic induction effect.
[0031] Structure of the retaining ring 300 and tensioning screws 310: The retaining ring 300 is a composite ceramic component, and its inner side is bonded to the surface of the collar seat 210. The retaining ring 300 is fixed to the upper and lower sides of the collar seat 210 by several tensioning screws 310. The tensioning screws 310 can be used to lock various parts of the stator assembly 200, ensuring that the assembly does not loosen during operation. The surface of the retaining ring 300 is provided with multiple tensioning screws 310 to increase the fixing stability. The outer side of the retaining ring 300 is provided with slots for positioning the tensioning screws 310.
[0032] Assembly Process: First, the collar seat 210 is inserted one-to-one with the magnetic yoke block 220 and coil assembly 230, ensuring a tight fit between the slots and pins. Then, the sheath ring 300 is fixed to the upper and lower sides of the collar seat 210 using the tension screw 310, completing the assembly of the stator assembly 200. Finally, the rotor shaft 100 and permanent magnet block 110 are embedded inside the stator assembly 200, and the rotor shaft 100 is fixed using bearings or other connection methods, allowing it to rotate freely within the stator assembly 200. Example 2
[0033] In this embodiment, the sheath ring 300 is made of composite ceramic material, giving it better high-temperature resistance and corrosion resistance. Furthermore, the inner side of the magnetic yoke block 220 has an arc groove to match the surface of the permanent magnet block 110, further enhancing the stability and electromagnetic induction efficiency of the component. The magnetic yoke block 220 is in close contact with the inner side of the sheath seat 210 through a thermally conductive grease layer, ensuring rapid heat dissipation and preventing overheating that could damage the component.
[0034] In practical applications, the quick-installation stator and rotor assembly of this invention can be quickly disassembled and installed, and the connections of each part are stable. It is suitable for high-frequency start-up and shutdown environments and has good durability and high energy conversion efficiency.
[0035] Working principle and usage process of this utility model:
[0036] The quick-assembly stator-rotor assembly of this invention mainly consists of a rotor shaft 100, a stator assembly 200, and a retaining ring 300. A permanent magnet block 110 is mounted on the rotor shaft 100. The permanent magnet block 110 and the magnetic yoke block 220 are arranged opposite each other to form a magnetic field, which interacts with the coil assembly 230 in the stator assembly. During operation, the relative movement between the permanent magnet block 110 and the coil assembly 230 generates electromagnetic force, thereby driving the stator-rotor assembly to work.
[0037] The stator assembly 200 includes a collar seat 210, a yoke block 220, and a coil assembly 230. The retaining ring 300 securely fastens the collar seat 210 and the yoke block 220 together via a tension screw 310, ensuring the stability of the assembly. The retaining ring 300 can be easily assembled and disassembled by removing the tension screw 310, facilitating maintenance and replacement.
[0038] The entire stator and rotor assembly is assembled in a detachable manner, and the connection of each part adopts a locking device, which can effectively improve the reliability and stability of the assembly, while facilitating quick assembly and maintenance.
