Description

Technical Field

[0001] This utility model relates to a slip shaft component, and more particularly to a high energy density composite conductor ring. Background Technology

[0002] The upper limit of the winding force of a magnetically controlled slip differential mechanism can be increased by increasing the magnetic flux density per unit cross-sectional area of ​​the conductor ring. Without breakthroughs in permanent magnet materials, the performance limit of the mechanism could previously only be increased by increasing the magnet volume, number of magnets, or magnet arrangement. However, these methods increase the size and cost of the mechanism. Therefore, some small-volume slip differential mechanisms, such as 3-inch models, have a lower upper limit of winding force and cannot meet the requirements of high-tension winding. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a composite conductor ring that solves at least one of the above problems.

[0004] This invention provides a high energy density composite conductor ring, comprising a ring-shaped composite metal sheet and a magnetically conductive layer disposed on the composite metal sheet;

[0005] The composite metal sheet is a conductive but non-magnetic material, while the magnetic layer is a magnetic material.

[0006] The thickness of the magnetic layer is greater than 30 micrometers, and its relative permeability is between 500 ur and 10000 ur.

[0007] The magnetically conductive layer is used to alter the magnetic field density distribution of the permanent magnet mechanism, increasing the magnetic field density per unit cross-sectional area passing through the composite metal sheet. This enhances the induced Foucault current generated within the conductor ring during relative motion between the conductor ring and the permanent magnet mechanism. Compared to existing products, with the same volume and relative speed difference, the added magnetically conductive layer significantly improves the winding force of the conductor ring.

[0008] As a further aspect of this invention, it also includes a support, with the magnetically conductive layer facing the support and sandwiched between the composite metal sheet and the support. Its magnetic conductivity is used to restrict the diffusion of magnetic field lines, making the magnetic field lines passing through the composite metal sheet denser.

[0009] As a further improvement of this invention: the support is made of alloy or polymer material. This reduces the cost or weight inertia of the conductor ring.

[0010] As a further embodiment of this invention: a composite metal sheet is applied to the inner edge of the body. This is suitable for assembly configurations where the conductor ring and the permanent magnet mechanism are radially coupled.

[0011] As a further embodiment of this invention: a composite metal sheet is applied to the end face of one end of the body. This is suitable for assembly configurations where the conductor ring and the permanent magnet mechanism are axially coupled.

[0012] As a further embodiment of this utility model: the composite conductor ring is installed opposite to the permanent magnet mechanism in the equipment, and there is an air gap between the two and they operate coaxially.

[0013] The aforementioned composite conductor ring employs a method of adding a layer of highly permeable magnetic material to the outside of the composite metal sheet to change the magnetic field line distribution density and increase the magnetic field line density per unit cross-sectional area passing through the composite metal sheet. This achieves the effect of effectively increasing the upper limit of the tension of the winding mechanism while maintaining a small volume conductor ring. Attached Figure Description

[0019] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] The distribution details of physical quantities in the accompanying drawings are simplified. The images are only for the purpose of describing the essence of this utility model. The simplified physical features are for illustration only, and do not indicate or imply the scientific characteristics that the physical quantities should have. This simplified expression should not be construed as an incorrect reference, and therefore does not limit the effectiveness and adaptability of this utility model.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In this embodiment, as Figures 1-4 As shown, a high energy density composite conductor ring includes a ring-shaped composite metal sheet 100 and a magnetically conductive layer 200 disposed on the composite metal sheet.

[0024] The composite metal sheet 100 is a conductive but non-magnetic material, and the magnetic layer 200 is a magnetic material.

[0025] The thickness of the magnetic layer 200 is greater than 30 micrometers, and its relative permeability is between 500 ur and 10000 ur.

[0026] It should be noted that the magnetic conductive layer 200 can be a plating layer, a foil, or a sheet, and can be bonded to the composite metal sheet 100 by sputtering, vapor deposition, electroplating, bonding with structural double-sided adhesive, or brushing or spraying a coating containing magnetic conductive powder solid content.

[0027] like Figure 2 As shown, the magnetic conductive layer 200 is used to change the magnetic field line distribution density of the permanent magnet mechanism, thereby increasing the magnetic field line density per unit cross-sectional area passing through the composite metal sheet 100. This enhances the induced Foucault current generated within the conductor ring when the conductor ring and the permanent magnet mechanism 300 move relative to each other. Compared to existing products, with the same volume and rotational speed difference, the increased magnetic conductive layer effectively improves the winding force of the conductor ring.

[0028] Furthermore, it also includes a support 400, with the magnetically conductive layer 200 facing the support 400 and sandwiched between the composite metal sheet 100 and the support 400. This is used to induce and suppress the distribution pattern of magnetic field lines, making the magnetic field lines passing through a unit cross-sectional area of ​​the composite metal sheet 100 more dense.

[0029] The support 400 is made of alloy or polymer material to reduce the cost, weight, and inertia of the conductor ring. For example, a support 400 made of engineering plastic will be much lighter than one made of metal. When the composite conductor ring is used as a driven rotating component, it will have less inertia, avoiding the risk of mechanical resonance and making the equipment operate more stably.

[0030] In the device, the composite conductor ring is mounted opposite the permanent magnet mechanism, with an air gap between them and coaxial. When the conductor ring is the driven component, the composite conductor ring is located on the outer side, and the composite metal sheet 100 covers the inner edge of the body. This is suitable for assembly forms where the conductor ring and the permanent magnet mechanism are radially coupled. Alternatively, if the conductor ring is the driving component, i.e., the power source, and the permanent magnet is located on the outer side, the composite metal sheet 100 is positioned on the outer edge of the body. Figure 4 In this configuration, the permanent magnet is the active component that rotates with the main shaft, meaning the composite conductor ring is located on the outside, and the two are radially distributed; as mentioned above, their positions can be interchanged.

[0031] As a second embodiment of this utility model, the difference from the first embodiment is that, Figure 5 As shown, a composite metal sheet covers one end face of the body. This is suitable for assembly configurations where the conductor ring and permanent magnet mechanism are axially coupled.

[0032] The magnetic conductive layer of the composite metal sheet can be constructed by sputtering, evaporation, electroplating, structural double-sided adhesive bonding, or by brushing or spraying a coating containing magnetically conductive powder solids.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
