Description
Technical Field
[0001] This application relates to the field of magnets, and more particularly to a high-magnetic toroidal magnet. Background Technology
[0002] High-magnetic toroidal magnets are a type of magnet with strong magnetic properties and a circular shape. They are commonly used in power generation equipment, high-performance motors, and automation equipment. Their high magnetic strength and good magnetic field characteristics help improve the overall efficiency of motors, making them run more smoothly and with greater torque. With the continuous advancement of technology, the performance requirements for high-magnetic toroidal magnets are becoming increasingly stringent. Developing magnet materials with higher magnetic energy product, higher coercivity, and better temperature stability is one of the future development directions.
[0003] Currently, high-magnetic ring magnets have poor high-temperature resistance and wear resistance. After prolonged use, due to their insufficient high-temperature resistance and wear resistance, the ring magnets are easily damaged, thus shortening their service life and affecting their normal use. Utility Model Content
[0004] The purpose of this invention is to provide a high-magnetic circular annular magnet to solve the problems mentioned in the background art.
[0005] This utility model provides a high-magnetic circular annular magnet, comprising:
[0006] The high-magnetic annular magnet provided in this application adopts the following technical solution: it includes an annular magnet body, and high-temperature resistant layers are provided on the upper, lower, inner and outer sides of the annular magnet body. Wear-resistant layers are provided on the upper, lower and inner sides of the high-temperature resistant layers. Waterproof layers are provided on the upper, lower and outer sides of the wear-resistant layers. Anti-corrosion layers are provided on the upper, lower and outer sides of the waterproof layers. Anti-oxidation layers are provided on the upper, lower and outer sides of the anti-corrosion layers.
[0007] By adopting the above technical solutions, the high-temperature resistant layer protects the annular magnet body from high temperatures, maintaining magnetic stability; the wear-resistant layer reduces wear and extends service life; the waterproof layer prevents moisture from entering the annular magnet body, reducing the probability of rust or oxidation; the anti-corrosion layer prevents rust from contacting air and moisture, thus preventing rust from affecting structural strength and magnetism; and the anti-oxidation layer prevents oxidation of the annular magnet body surface, improving service life.
[0008] Preferably, the annular magnet body has a transverse annular groove inside, and a transverse reinforcing ring is provided inside the transverse annular groove. Vertical annular grooves are provided on the upper and lower sides of the transverse reinforcing ring, and vertical reinforcing rings are provided inside the vertical annular grooves.
[0009] By adopting the above technical solutions, when the annular magnet body is subjected to torque load, the transverse reinforcing ring set in the transverse annular groove can resist circumferential deformation and prevent the ring from torsional deformation or breakage. When the annular magnet body is subjected to compression or bending, it is prone to circumferential buckling. The transverse reinforcing ring set in the transverse annular groove can increase the circumferential bending modulus of the ring and avoid instability. In an alternating magnetic field, the annular magnet body may be subjected to circumferential electromagnetic force. The transverse reinforcing ring set in the transverse annular groove can evenly disperse such force and reduce local magnetostrictive deformation. When the annular magnet body is subjected to axial load, the vertical reinforcing ring set in the vertical annular groove can resist axial deformation and prevent the ring from bending or breaking along the axial direction. The annular magnet body may generate radial vibration in high-speed rotation or alternating magnetic field. The vertical reinforcing ring set in the vertical annular groove can suppress radial deformation and maintain the roundness of the ring. The annular magnet body will generate thermal expansion and contraction when the temperature changes. The vertical reinforcing ring set in the vertical annular groove can guide the release of thermal stress along the axial direction and avoid structural damage caused by thermal deformation.
[0010] Preferably, the high-temperature resistant layer is made of aluminum oxide.
[0011] By adopting the above technical solution, alumina has good chemical stability and does not react with the ring magnet body, which is beneficial to protecting the ring magnet body.
[0012] Preferably, the wear-resistant layer is made of stainless steel.
[0013] By adopting the above technical solutions, stainless steel has good machinability and can be formed by stamping and welding. The surface can be further hardened, such as by nitriding treatment, which can improve wear resistance and extend the service life of the ring magnet body.
[0014] Preferably, the waterproof layer is made of silicone rubber.
[0015] By adopting the above technical solutions, silicone rubber has strong ozone resistance and weather resistance, is not easy to age in outdoor or humid environments, and has a dense molecular structure with extremely low water vapor permeability, which can block moisture for a long time. It can adapt to the curved surface structure of the ring magnet body, resist vibration and deformation, is not easy to crack, and is suitable for waterproofing requirements in high-temperature environments, which is conducive to the long-term use of the ring magnet body.
[0016] Preferably, the anti-corrosion layer is made of zinc alloy.
[0017] By adopting the above technical solution, the standard electrode potential of zinc is lower than that of iron, so it can be used as a sacrificial anode to protect the ring magnet body. The zinc-nickel alloy has extremely high corrosion resistance, which is beneficial to protecting the ring magnet body.
[0018] Preferably, the material of the anti-oxidation layer is a nickel-based alloy.
[0019] By adopting the above technical solution, the nickel-based alloy has a high nickel content, high oxidation resistance temperature, good resistance to sulfidation and halide corrosion, and good ductility, which is beneficial to protecting the ring magnet body and extending the service life of the ring magnet body.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. By setting a high-temperature resistant layer, the ring magnet body is protected from high temperature and the magnetic stability is maintained. The wear-resistant layer can reduce wear and extend service life. The waterproof layer will prevent water from entering the ring magnet body and reduce the probability of rust or oxidation. The anti-corrosion layer can prevent rust from contact with air and moisture, which will affect the structural strength and magnetism. The anti-oxidation layer will prevent the surface of the ring magnet body from oxidizing and improve service life.
[0022] 2. When the annular magnet body is subjected to torque load, the transverse reinforcing rings set in the transverse annular groove can resist circumferential deformation and prevent the ring from torsional deformation or breakage. The annular magnet body is prone to circumferential buckling when under compression or bending. The transverse reinforcing rings set in the transverse annular groove can increase the circumferential bending modulus of the ring and avoid instability. In an alternating magnetic field, the annular magnet body may be subjected to circumferential electromagnetic force. The transverse reinforcing rings set in the transverse annular groove can evenly disperse such force and reduce local magnetostrictive deformation. When the annular magnet body is subjected to axial load, the vertical reinforcing rings set in the vertical annular groove can resist axial deformation and prevent the ring from bending or breaking along the axial direction. The annular magnet body may generate radial vibration in high-speed rotation or alternating magnetic field. The vertical reinforcing rings set in the vertical annular groove can suppress radial deformation and maintain the roundness of the ring. The annular magnet body will undergo thermal expansion and contraction when the temperature changes. The vertical reinforcing rings set in the vertical annular groove can guide the release of thermal stress along the axial direction and avoid structural damage caused by thermal deformation.
