Description

Technical Field

[0001] This utility model belongs to the field of slip ring technology, and specifically relates to a simplified slip ring. Background Technology

[0002] Slip rings, as key components for transmitting electricity, signals, or other media between rotating parts and stationary structures, are widely used in numerous devices requiring continuous rotation and simultaneous power or data exchange, such as wind turbines, automated robots, and medical imaging equipment. They achieve stable current and signal transmission through an internal conductive ring and brushes (or contact points). However, traditional slip rings exhibit several drawbacks in practical applications. Under high-speed rotation, poor contact is prone to occur, leading to unstable current transmission. This can have a significant negative impact on the performance and reliability of the entire system in industrial automation and robotics fields. Furthermore, traditional slip rings are mostly complex in structure and have high maintenance costs. Therefore, a simplified slip ring was designed to address these problems.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a simple slip ring.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a simplified slip ring, comprising: The main body has a mounting hole in a first direction and an insertion hole at its upper end, which is connected to the mounting hole. A conductive component, the lower end of which is inserted into the interior of the main body through the socket; The main body is provided with bearings at both ends in the first direction, and the bearings are located in the mounting holes and are coaxially arranged with the mounting holes.

[0006] Furthermore, washers are affixed to both sides of the bearing, and sealing rings are also provided at both ends of the main body in the first direction. The sealing rings are located on the outer side of the bearing on the same side, and are all located within the mounting holes, coaxially arranged with the mounting holes. In this design, the sealing rings provide a better sealing effect, allowing the slip ring to be used in environments with acidic or alkaline gases, thus expanding its applicability.

[0007] Furthermore, the main body is provided with sealing and clamping rings at both ends in the first direction. These sealing and clamping rings are located outside the sealing ring on the same side and are coaxially arranged with the mounting hole. In this design, the sealing and clamping rings can tighten the sealing ring, improving the sealing effect.

[0008] Furthermore, the conductive component includes a connecting plate, an adapter plate, a first comb plate, and a second comb plate. The adapter plate is arranged parallel to the upper surface of the main body, and the connecting plate is vertically arranged on the upper end of the adapter plate. A connecting hole is provided on the connecting plate, and the first and second comb plates are vertically arranged on the lower end of the connecting plate. In this design, the connecting plate, adapter plate, first comb plate, and second comb plate are integrally formed, resulting in a more stable structure.

[0009] Furthermore, a support block is provided on the wall of the socket to support the adapter plate, and the adapter plate is snapped onto the support block. In this design, two support blocks can be used to make the support more stable.

[0010] Furthermore, a sealing gasket is provided inside the socket, and the sealing gasket is fitted over the upper end of the conductive component, with the upper end face of the sealing gasket flush with the upper end face of the main body. In this design, the lower end face of the sealing gasket is located on the adapter plate, and the sealing gasket at the socket serves a sealing function.

[0011] Furthermore, a connecting shaft is inserted into the mounting hole. The connecting shaft is coaxially arranged with the mounting hole, the washer, the sealing ring, and the sealing clamping ring. Both ends of the connecting shaft extend out of the main body, and the connecting shaft is electrically connected to the conductive component.

[0012] Furthermore, the distance between the first and second comb plates is adapted to the outer diameter of the connecting shaft. When the connecting shaft is located within the mounting hole, both the first and second comb plates are in contact with the connecting shaft. This ensures that the conductive component is electrically connected to the connecting shaft.

[0013] Furthermore, both ends of the connecting shaft extending from the main body are provided with flat sections. In this design, the flat sections prevent relative rotation with mating parts, provide a clear installation direction, and reduce adjustment time during assembly.

[0014] Furthermore, the bearing is a spherical bearing. In this design, compared to traditional ball bearings, spherical bearings reduce the coefficient of friction, decrease wear rate, and reduce maintenance frequency.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: The simplified slip ring designed in this utility model has a simple structure and low maintenance cost. The conductive component with a comb-tooth plate structure realizes multi-point contact with the rotating part, ensuring that the current transmission can be maintained stably when the rotating part is in any position. It can meet the requirements of high-speed rotation conditions, is not prone to poor contact, and has stable current transmission. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] Example 1: See appendix Figure 1 and attached Figure 2 As shown, this embodiment provides a simplified slip ring, including: The main body 1 has a mounting hole 2 in the first direction and an insertion hole 3 at its upper end, which communicates with the mounting hole 2. The main body 1 is a one-piece structure. A sealing gasket 10 is installed inside the insertion hole 3, and the sealing gasket 10 is fitted onto the upper end of the conductive component 4, with the upper end face of the sealing gasket 10 flush with the upper end face of the main body 1. The lower end face of the sealing gasket 10 is located on the adapter plate 42. The sealing gasket 10 at the insertion hole 3 provides a sealing function. The main body 1 is made of high-strength alloy materials, such as aluminum alloy or stainless steel, to ensure the stability and corrosion resistance of the device structure. Different rotating parts can be connected to both sides of the mounting hole 2 according to the working requirements of the equipment.

[0023] Conductive component 4, see appendix Figure 5 As shown, the lower end of the conductive component 4 is inserted into the interior of the main body 1 through the insertion hole 3. The conductive component 4 includes a connecting plate 41, an adapter plate 42, a first comb plate 43, and a second comb plate 44. The adapter plate 42 is parallel to the upper surface of the main body 1, and the connecting plate 41 is vertically positioned above the adapter plate 42 (the connecting plate 41 is centered relative to the adapter plate 42). The connecting plate 41 has a connecting hole 45. The first comb plate 43 and the second comb plate 44 are vertically positioned at the lower end of the connecting plate 41. The first comb plate 43 and the second comb plate 44 are respectively located on opposite sides of the lower surface of the adapter plate 42, and the distance between the first comb plate 43 and the second comb plate 44 is adapted to the diameter of the mounting hole 2. The connecting plate 41, the adapter plate 42, the first comb plate 43, and the second comb plate 44 are integrally formed, resulting in a more stable structure.

[0024] The conductive component 4 is made of pure copper or silver-plated copper to ensure conductivity. The connection hole 45 of the conductive component 4 facilitates wiring and connection. The comb-tooth structure of the conductive component 4 enables multi-point contact with the rotating parts, ensuring stable current transmission regardless of the position of the rotating parts. Even under high-speed rotation conditions, poor contact is unlikely to occur, and current transmission remains stable.

[0025] Bearings 5 ​​are provided at both ends of the main body 1 in the first direction. The bearings 5 ​​are located in the mounting holes 2 and are coaxially arranged with the mounting holes 2. The number of bearings 5 ​​on both sides is equal and there is at least one. The bearings 5 ​​are high-precision rolling bearings, preferably models with low friction coefficient and good wear resistance, to ensure that the device can maintain stable performance even under high-speed rotation.

[0026] Both sides of the bearing 5 are fitted with washers 6, and the main body 1 is also provided with sealing rings 7 at both ends in the first direction. The sealing rings 7 are located on the outer side of the bearing 5 on the same side (the sealing rings 7 are located outside the outer washer 6 of the outer side of the bearing 5). The sealing rings 7 are all located inside the mounting holes 2 and are coaxially arranged with the mounting holes 2. The sealing rings 7 can provide a better sealing effect, allowing the slip ring to be used in environments with acidic or alkaline gases, thus expanding its application range. The bearing 5 is preferably a spherical bearing 5, but the bearing 5 is not limited to spherical bearings. Other types of bearings with low coefficient of friction are within the protection scope of this patent document. Compared with traditional ball bearings 5, spherical bearings 5 ​​reduce the coefficient of friction, reduce the wear rate, and reduce the maintenance frequency. The sealing rings 7 are made of rubber or polyurethane to ensure that they can adapt to the electroplating environment and meet the requirements for the use of slip rings in chain-type horizontal electroplating equipment. The washers 6 are made of wear-resistant plastic or ceramic materials and are used to adjust the clearance, absorb vibration, reduce instability caused by mechanical movement, and enhance the durability of the device.

[0027] The main body 1 is also provided with sealing and clamping rings 8 at both ends in the first direction. The sealing and clamping rings 8 are located outside the sealing ring 7 on the same side, and are coaxially arranged with the mounting hole 2. The sealing and clamping rings 8 can clamp the sealing ring 7 and improve the sealing effect.

[0028] See appendix Figure 4 As shown, a support block 9 is provided on the wall of the socket 3 to support the adapter plate 42, and the adapter plate 42 is snapped onto the support block 9. Two support blocks 9 can be provided to make the support more stable.

[0029] See appendix Figure 2 and attached Figure 3 As shown, a first step 21 and a second step 22 are provided on the inner sides of both ends of the mounting hole 2. The first step 21 is located inside the second step 22. The bearing 5 and the washer 6 are both located at the position of the first step 21, and the sealing ring 7 and the sealing clamping ring 8 are both located at the position of the second step 22. The steps can play a role in limiting and supporting, making the structure more stable.

[0030] Slip ring installation: Secure the slip ring body 1 to the predetermined position using fasteners such as brackets and bolts, adjusting it to the optimal horizontal state to minimize additional stress generated during operation. Install the bearing 5, ensuring correct alignment to avoid accelerated wear due to misalignment. Securely connect the conductive component 4, ensuring a stable connection and excellent contact. Install the sealing ring 7, washer 6, and sealing compression ring 8 in an orderly manner, thoroughly inspecting all connections to ensure a tight, seamless fit.

[0031] Example 2: This embodiment is a further improvement based on Embodiment 1, and its specific method is as follows: See appendix Figure 6 Appendix Figure 7 Appendix Figure 10 and attached Figure 11 As shown, a connecting shaft 11 is inserted into the mounting hole 2. The connecting shaft 11, mounting hole 2, washer 6, sealing ring 7, and sealing clamping ring 8 are all coaxially arranged. Both ends of the connecting shaft 11 extend out of the main body 1 and are electrically connected to the conductive component 4. The connecting shaft 11 is rotatably arranged within the mounting hole 2 and serves as a rotating component of the slip ring. As a rotating component, the connecting shaft 11 is connected to the corresponding structure of the equipment, and both sides rotate synchronously.

[0032] See appendix Figure 8 As shown, the distance between the first comb plate 43 and the second comb plate 44 is adapted to the outer diameter of the connecting shaft 11. When the connecting shaft 11 is located in the mounting hole 2, both the first comb plate 43 and the second comb plate 44 are in contact with the connecting shaft 11. This ensures that the conductive component 4 is electrically connected to the connecting shaft 11.

[0033] See appendix Figure 9 As shown, both ends of the connecting shaft 11 extending from the main body 1 are provided with flat sections 12. The flat sections 12 can prevent relative rotation with mating parts, provide a clear installation direction, and reduce adjustment time during assembly.

[0034] Installation Requirements: Select suitable installation sites according to equipment design requirements, ensuring convenient connection of fixed structures and rotating parts, as well as ventilation needs for the slip ring, and guaranteeing a normal working environment. Securely position the slip ring in the selected location using fasteners such as brackets and bolts, verifying horizontal and vertical alignment to ensure unobstructed rotation of the rotating parts.

[0035] The simplified slip ring designed in this utility model has a simple structure and low maintenance cost. The conductive component with a comb-tooth plate structure realizes multi-point contact with the rotating part, ensuring that the current transmission can be maintained stably when the rotating part is in any position. It can meet the requirements of high-speed rotation conditions, is not prone to poor contact, and has stable current transmission.

[0036] The slip ring designed in this invention is mainly used in chain-type horizontal electroplating equipment. In the traditional power transmission structure of chain-type horizontal electroplating equipment, the length of the conductive shaft is relatively large (usually 1.5m~1.8m), and it usually adopts single-sided power connection, which easily leads to uneven power between the near and far ends of the conductive component. However, the slip ring design allows the power to be input from the middle position of the conductive component, which is equivalent to reducing the distance between the near and far ends by half. The power is relatively more uniform, which can maintain stable current transmission and meet more operating conditions.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
