Description

A composite conductive slip ring Technical Field

[0001] This utility model relates to the field of conductive slip ring technology, and in particular to a combined conductive slip ring. Background Technology

[0002] Composite conductive slip rings, as electromechanical components capable of transmitting multiple signals and energy sources between rotating and stationary parts, are widely used in numerous fields such as industrial automation, aerospace, and energy. They primarily achieve the transmission of various media, including electricity, signals, gases, and liquids, through the sliding contact between brushes and conductive rings, combined with insulating parts, supporting and fixing parts, and special transmission channels.

[0003] Composite conductive slip rings typically need to have the following functional structures:

[0004] 1. The conductive ring body is the core component of the conductive slip ring. It is made of a metal material with high conductivity, which can ensure the stable transmission of current and signal.

[0005] 2. The brush is in close contact with the conductive ring, and the transmission of current and signal is achieved through sliding friction. It is required to have good wear resistance and conductivity.

[0006] 3. Insulating material is used to isolate the conductive ring, prevent short circuits between different circuits, and ensure the accuracy of signal transmission;

[0007] 4. The outer shell protects and supports the internal structure, while also providing an interface for the installation and fixing of the conductive slip ring.

[0008] Currently, there are various conductive slip ring products on the market. Some conductive slip rings adopt an integral shell design with a relatively fixed internal structure. The rotor and shaft are mostly fixed with a single screw. In order to improve the stability of conductive slip rings, some manufacturers have tried to optimize the internal structure by improving the brush material and the surface treatment process of the conductive ring, which has improved the conductivity to a certain extent. Other manufacturers have enhanced the protective ability of slip rings in harsh environments by strengthening the sealing design.

[0009] However, the above-mentioned implementation still has the following problems. In terms of connection stability, the method of fixing the rotor and shaft with a single screw is difficult to resist the centrifugal force and vibration generated during equipment operation. After long-term use, it is easy to loosen, resulting in unstable signal transmission or even interruption, affecting the normal operation of the equipment. In terms of product versatility, the integrated design of the conductive slip ring is difficult to adapt to different sizes and types of internal structures, and cannot meet the needs of diverse application scenarios. If different specifications are to be adapted, redesign and production are often required, which leads to a significant increase in R&D and production costs. In response to this problem, this application proposes a solution: designing a conductive slip ring with a combined shell design, built-in serrated heat dissipation fins, and a double screw fixing structure to achieve good anti-loosening effect and high specification adaptability. Summary of the Invention

[0010] To address the shortcomings of existing technologies, this utility model provides a combined conductive slip ring, which solves the problem that the method of fixing the rotor and shaft with a single screw is difficult to resist the centrifugal force and vibration generated during equipment operation. After long-term use, it is prone to loosening, resulting in unstable or even interrupted signal transmission, affecting the normal operation of the equipment. In terms of product versatility, the integral design of the conductive slip ring is difficult to adapt to different sizes and types of internal structures, and cannot meet the needs of diverse application scenarios.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A combined conductive slip ring includes a slip ring stator and a slip ring rotor. A housing is movably fitted onto the annular side of the slip ring stator. A set of heat dissipation fins is fixedly connected to the annular side of the housing. A connecting ring is provided on the upper surface of the slip ring stator. Two screws are threaded onto the upper surface of the slip ring stator. A set of screws is threaded onto the annular side of both the slip ring rotor and the connecting ring. A protective mesh is fixedly connected to the surface of the slip ring stator. Two positioning blocks for positioning are fixedly connected to the upper surface of the slip ring stator. A set of retaining strips is fixedly connected to the inner wall of the housing. Both screws are threaded onto the connecting ring.

[0013] Preferably, the lower surface of the connecting ring has two positioning grooves, which are respectively engaged with two positioning blocks. The upper surface of the outer shell has two limiting blocks fixedly connected, which are respectively engaged with two screws.

[0014] Preferably, the surface of the slip ring stator has two rectangular grooves, which are respectively engaged with two limiting blocks. The annular side of the slip ring stator has a set of slots, which are respectively engaged with a set of locking strips.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the device is running, the slip ring rotor will be subjected to various forces, such as centrifugal force and vibration force. If it is only fixed by a single screw, it may loosen due to vibration after long-term use. The outer compression fixing screw can provide additional tightening force, making the connection between the slip ring rotor and the shaft tighter, effectively preventing the slip ring rotor from shifting or loosening on the shaft, and ensuring the normal operation of the device.

[0017] 2. The modular design of the housing allows for the replacement of different components to accommodate the internal structures of conductive slip rings of different sizes and types. For conductive slip rings of the same series but with different power or number of channels, the same basic housing frame can be used. Only some specific components that match the internal structure, such as mounting brackets and insulating partitions, need to be replaced to achieve the assembly of products of different specifications, thereby improving the versatility of the housing and reducing production costs.

The application designs a conductive slip ring with a combined shell, built-in serrated heat dissipation fins, and a double screw fixing structure to achieve good anti-loosening effect and high specification adaptability.

[0025] Example

[0026] As shown in Figures 1, 2, 3, and 4, the technical solution in this embodiment effectively solves the problem that the method of fixing the rotor and shaft with a single screw is difficult to resist the centrifugal force and vibration generated during equipment operation. After prolonged use, the screw is prone to loosening, leading to unstable or even interrupted signal transmission, affecting the normal operation of the equipment. Furthermore, in terms of product versatility, the integral design of the conductive slip ring is difficult to adapt to different sizes and types of internal structures, failing to meet the needs of diverse application scenarios. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a combined conductive slip ring, including a slip ring stator 1 and a slip ring rotor 2. A housing 8 is movably sleeved on the annular side of the slip ring stator 1. A set of heat dissipation fins 9 are fixedly connected to the annular side of the housing 8. A connecting ring 4 is provided on the upper surface of the slip ring stator 1. Two screws 6 are threaded onto the upper surface of the slip ring stator 1. A set of screws 5 are threaded onto the annular side of both the slip ring rotor 2 and the connecting ring 4. A protective mesh 3 is fixedly connected to the surface of the slip ring stator 1. Two positioning blocks 10 are fixedly connected to the upper surface of the slip ring stator 1. A set of retaining strips 14 are fixedly connected to the inner wall of the housing 8. Both screws 6 are threaded onto the connecting ring 4. During use, the output shaft of the equipment passes through the slip ring rotor 2, and the slip ring rotor 2 is connected to the connecting ring 4 via the retaining strips 14. A set of screws 5 is used for limiting and fixing. To ensure the tightness of the connection, a connecting ring 4 is fixedly connected to the upper surface of the slip ring stator 1 by two screws 6. The connecting ring 4 is positioned by two positioning blocks 10 fixed on the slip ring stator 1. After the connecting ring 4 is fixed, the set of screws 5 on it is rotated to press and fix it against the screws 5 on the slip ring rotor 2. When the device is running, the slip ring rotor 2 will be subjected to various forces, such as centrifugal force and vibration force. If it is fixed by only a single screw 5, it may loosen due to vibration after long-term use. The outer pressing and fixing screws 5 can provide additional fastening force, making the connection between the slip ring rotor 2 and the shaft tighter, effectively preventing the slip ring rotor 2 from shifting or loosening on the shaft, and ensuring the normal operation of the device.

[0028] Two positioning grooves 11 are formed on the lower surface of the connecting ring 4, and the two positioning grooves 11 are respectively engaged with two positioning blocks 10. Two limiting blocks 7 are fixedly connected to the upper surface of the outer shell 8, and the two limiting blocks 7 are respectively threaded with two screws 6. Two rectangular grooves 12 are formed on the surface of the slip ring stator 1, and the two rectangular grooves 12 are respectively engaged with two limiting blocks 7. A set of retaining grooves 13 are formed on the annular side of the slip ring stator 1, and the set of retaining grooves 13 are respectively engaged with a set of retaining strips 14. The outer shell 8 is fixedly connected to the annular side of the slip ring stator 1 by screws 6, and the outer shell 8 protects it. A set of retaining grooves 13 are provided on the annular side of the outer shell 8. Heat dissipation fins 9 are used for heat dissipation. The serrated design of heat dissipation fins 9 increases the heat dissipation area. The outer shell 8 is movably connected to the slip ring stator 1 through a set of clips 14 fixed on it. The overall modular design of the outer shell 8 can adapt to the internal structure of different sizes and types of conductive slip rings by replacing different components. For conductive slip rings of the same series but with different power or different number of channels, the same basic frame of the outer shell 8 can be used. Only some specific components that match the internal structure, such as mounting brackets and insulating partitions, need to be replaced to achieve the assembly of products of different specifications, which improves the versatility of the outer shell 8 and reduces production costs.

[0029] Among them, the slip ring stator 1 is an important component of the combined conductive slip ring. It provides the installation base for other components.

[0033] Screw 5: Both the slip ring rotor 2 and the connecting ring 4 have screws on their sides. The screws on the slip ring rotor 2 are used for initial positioning and fixing, while the screws on the connecting ring 4 are used for pressing and fixing with the screws on the slip ring rotor 2, providing additional fastening force to prevent the slip ring rotor 2 from shifting or loosening.

[0034] Screw 26: Threaded onto the slip ring stator 1, used to fix the connecting ring 4, and works in conjunction with the connecting ring 4, positioning block 10, etc. to ensure the stability of the connecting ring 4, thereby enhancing the stability of the slip ring rotor 2 connection;

[0035] Limiting block 7: It is fixed on the upper surface of the outer shell 8, threadedly connected to screw 6, and simultaneously engaged with the rectangular groove 12 on the surface of the slip ring stator 1, thus limiting screw 6, preventing it from loosening, and ensuring the stability of the overall structure.

[0036] The outer casing 8 is movably sleeved on the annular side of the slip ring stator 1, which protects the internal components. The heat dissipation fins 9 on its side are used for heat dissipation and are movably connected to the slip ring stator 1 through the retaining strip 14, which can be adapted to various specifications.

[0040] Rectangular groove 12: It is formed on the surface of slip ring stator 1 and is movably engaged with limit block 7. Together with limit block 7, it limits screw 6 to prevent it from shaking and ensures the stability of the overall structure.

[0041] Slot 13: It is opened on the annular side of the slip ring stator 1 and is movably engaged with the retaining strip 14 on the inner wall of the housing 8, so that the connection between the housing 8 and the slip ring stator 1 is more stable, and at the same time it is convenient to replace the components of the housing 8 to adapt to different specifications.

[0042] Clip 14: Fixed to the inner wall of the outer shell 8, it is movably engaged with the slot 13 on the annular side of the slip ring stator 1, realizing the movable connection between the outer shell 8 and the slip ring stator 1.

[0043] Working principle:

[0044] During operation, the output shaft of the device passes through the slip ring rotor 2. The slip ring rotor 2 is fixed by a set of screws 5. To ensure a tight connection, a connecting ring 4 is fixedly connected to the upper surface of the slip ring stator 1 by two screws 6. The connecting ring 4 is positioned by two positioning blocks 10 fixed on the slip ring stator 1. After the connecting ring 4 is fixed, the set of screws 5 on it is rotated to press and fix it against the screws 5 on the slip ring rotor 2. When the device is running, the slip ring rotor 2 will be subjected to various forces, such as centrifugal force and vibration force. If it is fixed by only a single screw 5, it may loosen due to vibration after long-term use. The outer pressing and fixing screws 5 can provide additional fastening force, making the connection between the slip ring rotor 2 and the shaft tighter and effectively preventing the slip ring rotor 2 from slipping on the shaft. To prevent displacement or loosening, and to ensure the normal operation of the device, the annular side of the slip ring stator 1 is fixedly connected to the outer shell 8 by screws 6, which protects it. The annular side of the outer shell 8 is provided with a set of heat dissipation fins 9 for heat dissipation. The serrated design of the heat dissipation fins 9 increases the heat dissipation area. The outer shell 8 is movably connected to the slip ring stator 1 by a set of clips 14 fixed on it. The overall modular design of the outer shell 8 can adapt to the internal structure of different sizes and types of conductive slip rings by replacing different components. For conductive slip rings of the same series but with different power or different number of channels, the same basic frame of the outer shell 8 can be used. Only some specific components that match the internal structure, such as mounting brackets and insulating partitions, need to be replaced to achieve the assembly of products of different specifications, which improves the versatility of the outer shell 8 and reduces production costs.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
