Description

A slip ring structure Technical Field

[0001] The invention relates to the technical field of slip rings, in particular to a slip ring structure with good heat dissipation performance and easy manufacture and assembly. Background Art

[0002] Slip rings, as a crucial electrical component, are responsible for connecting rotating bodies and transmitting energy and signals. They are widely used in electromechanical systems that require 360° continuous rotation and the transmission of electrical and data signals from a fixed position to a rotating position.

[0003] However, traditional slip ring designs have several flaws. For example, adjacent collars often form tight contact, leaving insufficient space for the guide vanes to connect to the guide rings. To address this, manufacturers often create additional holes or notches in the collars. This not only increases manufacturing complexity but also compromises the collar's overall structural strength. Therefore, ensuring sufficient clearance between adjacent collars to allow for a stable connection between the guide vanes and guide rings while maintaining the collar's overall structural strength has become a pressing technical challenge. Summary of the Invention

[0004] This patented invention proposes a novel slip ring structure that, through its unique design, addresses the challenges of conventional slip rings. This structure creates a gap by providing a convex ring between adjacent shaft rings, providing ample space for the connection between the guide vane and the guide ring, ensuring a stable connection. Furthermore, by optimizing the size and shape of the conductor holes and incorporating retaining ribs and flanges, the structure improves the slip ring's heat dissipation, welding quality, and assembly ease. These improvements and innovations significantly enhance the performance and application range of the new slip ring structure.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a slip ring structure comprising a plurality of concentrically stacked shaft rings in a multi-layer structure, each shaft ring having a plurality of conductor holes arranged in an annular array and extending therethrough, the number of the conductor holes being no less than the total number of the shaft rings, and the conductor holes on each shaft ring being aligned one by one;

[0006] One side of the collar is provided with a convex ring protruding outward along the axial direction around the inner ring. When a plurality of the collars are stacked together, the convex ring will be clamped between two adjacent collars, so that there is a gap between the adjacent collars and they do not contact each other.

[0007] Each layer of the collars is provided with a guide piece, which passes through the conductor hole and extends into the gap between adjacent collars;

[0008] Each layer of the shaft rings is sleeved with a guide ring, and the guide rings and the guide plates are welded together in the gaps between adjacent shaft rings;

[0009] The collars of each layer are fixed together by fixing members;

[0010] The guide pieces welded on each layer of guide rings have different lengths. The lower the number of layers, the more shaft rings the guide pieces need to pass through, and the longer they need to be, to ensure that each guide piece can extend out of the shaft ring in the same direction for external connection.

[0011] In some embodiments, the inner space size of the conductor hole is larger than the corresponding size of the guide piece.

[0012] In some embodiments, a plurality of limiting edges are provided on a side of the shaft ring close to the convex ring, and the limiting edges are respectively arranged between adjacent conductor holes.

[0013] In some embodiments, a flange is integrally provided on the outer side wall of the collar.

[0014] In some embodiments, a plurality of annular grooves are formed on the outer wall of the guide ring.

[0015] In some embodiments, each of the collars is provided with a plurality of mounting holes arranged in a circular array, and the mounting holes on the collars are aligned one by one.

[0016] The fixing member is a bolt and nut assembly, which is used in conjunction with the mounting hole.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. The present invention forms a certain gap space by setting a convex ring between adjacent shaft rings, providing an ample environment for the connection between the guide vane and the guide ring. This design effectively avoids the problem of loose connection or disconnection caused by insufficient space, thereby significantly improving the connection stability of the slip ring structure and ensuring the reliable transmission of electrical signals. Although the present invention sets gaps between the shaft rings to facilitate connection and heat dissipation, the overall structural strength of the shaft ring is ensured to be unaffected through reasonable structural design and manufacturing process control. On the contrary, since the problem of structural weakening caused by additional openings or gaps in traditional designs is avoided, the slip ring structure of the present invention may have a greater advantage in overall strength.

[0019] 2. The internal dimensions of the conductor hole in this invention are designed to be larger than those of the guide vanes, creating a heat dissipation gap. This innovative design allows for the timely dissipation of heat generated by current flowing through the guide vanes, preventing localized overheating from impacting the slip ring's performance. This optimized heat dissipation not only extends the slip ring's service life but also improves its stability in high-power, high-speed applications.

[0020] 3. The limiting ridges on the collar of the present invention regulate the weld points between the guide blade and the guide ring, making the welding process more standardized and controllable. This not only improves the convenience of the welding operation but also significantly enhances the weld quality, reducing the risk of weak welds or weld fractures. High-quality welding ensures the electrical performance and overall reliability of the slip ring structure.

[0021] 4. The flange structure integrated into the outer wall of the collar facilitates gripping and positioning during assembly. This design innovation simplifies and expedits the slip ring assembly process, reducing the operator's skill and experience requirements. Furthermore, the simplified assembly process improves production efficiency and reduces manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0031] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] As shown in Figures 1-5, this embodiment discloses a slip ring structure comprising a plurality of concentrically stacked multi-layered shaft rings 1. Each shaft ring 1 is provided with a plurality of conductor holes 101 arranged in an annular array. The number of conductor holes 101 is not less than the total number of shaft rings 1, and the conductor holes 101 on each shaft ring 1 are aligned one by one.

[0033] One side of the collar 1 is provided with a convex ring 104 convex outwardly along the axial direction around its inner ring. When multiple collars 1 are stacked together, the convex ring 104 will be clamped between two adjacent collars 1, so that there is a gap between the adjacent collars 1 and they do not touch each other.

[0034] Each layer of the collars 1 is provided with a guide piece 3, and the guide piece 3 passes through the conductor hole 101 and extends into the gap between adjacent collars 1;

[0035] Each layer of the shaft ring 1 is sleeved with a guide ring 4, and the guide ring 4 and the guide plate 3 are welded together in the gap between adjacent shaft rings 1;

[0036] The collars 1 of each layer are fixed together by fixing members;

[0037] To ensure that each guide vane 3 can extend out of the collar 1 in the same direction for external connection, the guide vanes 3 welded to each layer of guide rings 4 vary in length. The lower the number of layers, the more collars 1 the guide vanes 3 must pass through, and the longer they require. Specifically, because the slip ring is composed of multiple stacked collars 1, each collar 1 has conductor holes 101 through which the guide vanes 3 must pass. Therefore, for guide rings 4 of different layers, the number of collars 1 that the guide vanes 3 must pass through varies. For guide rings 4 located at lower layers, the guide vanes 3 must pass through more collars 1 on the upper layers to extend externally. Therefore, these guide vanes 3 must be designed to be longer. Conversely, for guide rings 4 located at higher layers, the guide vanes 3 must pass through fewer collars 1. Therefore, these guide vanes 3 can be relatively shorter. This design ensures that all guide blades 3 maintain the same direction when extending from the collar 1 and have a moderate length, neither too long to cause waste or interference, nor too short to achieve the expected connection effect.

[0038] When assembling this type of slip ring, a layered assembly method from bottom to top can be used, specifically as follows: First, starting from the bottom-level collar 1, instead of directly assembling the guide vanes 3 with the collar 1, the guide vanes 3 are first welded to the guide rings 4 of the corresponding layer. Next, the guide rings 4 with welded guide vanes 3 are placed on the bottom-level collar 1, ensuring that the guide vanes 3 correctly pass through the conductor holes 101 on the collar 1. Next, take the second layer of collars 1 and, similarly, weld the guide vanes 3 and guide rings 4 of this layer. Then, combine the collars 1, guide vanes 3, and guide rings 4 of this layer together. This process is repeated to produce multiple combined structures of collars 1, guide vanes 3, and guide rings 4. Finally, each combined structure is stacked layer by layer and fixed with fixings to obtain a finished slip ring structure.

[0039] In this slip ring structure, due to the presence of the convex ring 104, there is still a gap between the adjacent layers of the shaft rings 1 after they are combined. The gap provides sufficient space for the connection between the guide plate 3 and the guide ring 4, which can ensure the stable connection between the guide plate 3 and the guide ring 4. There is no need to open or punch a hole on the shaft ring 1 in order to connect the guide plate 3 and the guide ring 4, which makes the overall structure simpler and easier to manufacture.

[0040] In some embodiments, as shown in FIG2 , the internal space size of the conductor hole 101 is larger than the corresponding size of the guide plate 3 , forming a heat dissipation gap to ensure that the guide plate 3 has space for heat dissipation while passing through the conductor hole 101 .

[0041] In some embodiments, as shown in FIG4 , a plurality of limiting ribs 103 are provided on one side of the collar 1 near the convex ring 104. These limiting ribs 103 are disposed between adjacent conductor holes 101. The limiting ribs 103 are designed to standardize the welds between the guide blade 3 and the guide ring 4, ensuring a more regular shape and distribution of the welds, thereby improving the weld quality between the guide blade 3 and the guide ring 4.

[0042] In some embodiments, as shown in Figures 1-2, a flange 2 is integrally provided on the outer side wall of the collar 1. The design of the flange 2 facilitates the gripping of the collar 1 during assembly, thereby facilitating the assembly operation of the collar 1.

[0043] In some embodiments, as shown in FIG5 , a plurality of annular grooves 401 are formed on the outer wall of the guide ring 4 . These annular grooves 401 can be machined by turning and are used for heat dissipation and sewage removal.

[0044] In some embodiments, as shown in FIG1-4 , each of the collars 1 is provided with a plurality of mounting holes 102 arranged in a circular array, and the mounting holes 102 on each of the collars 1 are aligned one by one;

[0045] The fixing member is a bolt and nut assembly 5, which is used in conjunction with the mounting hole 102 to fix the collars 1 at each layer.

[0046] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
