Description

Technical Field

[0001] The present invention relates to the technical field of conductive slip rings, and more particularly to a conductive slip ring connection structure. Background Art

[0002] A conductive slip ring is a type of rotary electrical connector, usually installed at the center of rotation of a device. Its function is to achieve electrical connection between two relatively rotating mechanisms by fixing the stator end of the conductive slip ring to the fixed shaft of the device while the rotor end of the conductive slip ring is moved by the rotating shaft of the device.

[0003] However, when the rotating shaft of the equipment moves the rotor end of the conductive slip ring, the gap between the two causes them to knock against each other, producing a metallic clashing sound. This in turn leads to increased wear between the metals, which is more noticeable at low speeds. Furthermore, this gap can cause backlash between the rotating shaft and the rotor end of the conductive slip ring, resulting in inaccurate rotation angles and a significant impact on systems that require precise rotation angle control. Summary of the Invention

[0004] (1) Technical issues to be resolved The technical problem to be solved by the present invention is that there is a gap between the existing rotating shaft and the rotor end of the conductive slip ring, which leads to increased wear and generation of backlash.

[0014] (3) Beneficial effects The above technical solution of the present invention has at least the following advantages: In the present invention, a shift fork sleeve is provided between the shift fork disc of the rotating shaft and the shift fork at the conductive slip ring rotor end. The shift fork sleeve is made of a wear-resistant material. The shift fork sleeve fills the assembly gap between the conductive slip ring rotor end and the rotating shaft while isolating the rotating shaft from the conductive slip ring rotor end, thereby avoiding direct hard contact between the rotating shaft and the conductive slip ring rotor end, thereby avoiding increased wear. In addition, the shift fork realizes a snap-on connection, thereby avoiding backlash between the rotating shaft and the conductive slip ring rotor end, and improving the accuracy of the rotation angle.

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is 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 the present invention and are not intended to limit the present invention.

[0022] It should be noted that when an element is referred to as being “fixed to” or “disposed on” another element, it may be directly located on the other element or indirectly located on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0023] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate that the device or element must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating relative importance or the number of technical features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined. The following is a more detailed description of the specific implementation of the present invention in conjunction with specific embodiments: like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a conductive slip ring connection structure, comprising a conductive slip ring rotor end 1, a rotating shaft 2, and a shift fork sleeve 3. A shift fork 11 is provided at the end of the conductive slip ring rotor end 1. A shift fork disc 21 is connected to the end of the rotating shaft 2, and the shift fork disc 21 is provided with a mounting hole 211. The shift fork sleeve 3 is provided with a mounting cavity 31, and the shift fork sleeve 3 is engaged with the mounting hole 211, and the shift fork 11 is engaged with the mounting cavity 31. Specifically, the conductive slip ring comprises a conductive slip ring rotor end 1 and a conductive slip ring stator end, wherein the conductive slip ring rotor end can rotate relative to the conductive slip ring stator end to ensure that the wires connected to the conductive slip ring rotor end 1 do not become entangled with the wires connected to the conductive slip ring stator end, while ensuring that the rotating shaft 3 can rotate normally.

[0025] Specifically, the implementation principles of this embodiment are as follows: The shift fork sleeve 3 is assembled onto the shift fork 11 of the conductive slip ring rotor end 1, that is, the shift fork 11 is snap-fitted and installed in the mounting cavity 31 of the shift fork sleeve 3, and the shift fork disc 21 is assembled onto the rotating shaft 2 of the device. The shift fork sleeve 3 is then snap-fitted into the mounting hole 211 of the shift fork disc 21, ultimately achieving a gap-free connection between the conductive slip ring rotor end 1 and the rotating shaft 2. The above technical solution prevents the conductive slip ring rotor end 1 and the rotating shaft 2 from knocking against each other due to clearance, emitting a metallic collision sound and subsequently increasing metal-to-metal wear. It also avoids backlash between the rotating shaft 2 and the conductive slip ring rotor end 1, improving the accuracy of the rotation angle. Compared to conventional structures, the various components of this embodiment are rationally designed, with a streamlined and compact mechanism, while also facilitating disassembly, maintenance, and replacement. Furthermore, by eliminating the assembly clearance through the shift fork sleeve 3, the rotating shaft can rotate smoothly, without any jerking during the entire rotation process, further improving the stability of the rotating shaft's rotation.

[0026] In one embodiment, the shift fork sleeve 3 is made of polytetrafluoroethylene. Specifically, polytetrafluoroethylene (PTFE) is a high-performance synthetic polymer material, commonly known as the "King of Plastics" or "Teflon," and possesses excellent chemical stability, corrosion resistance, and physical properties. Using PTFE to manufacture the shift fork sleeve 3 provides it with excellent wear resistance. Furthermore, PTFE has a relatively low hardness compared to metal materials and possesses inherent lubricating properties, thereby preventing metal-to-metal contact between the rotating shaft 2 and the shift fork 11, significantly reducing component wear caused by such contact.

[0027] In one embodiment, the cross section of the shift fork sleeve 3 is rectangular. By matching the rectangular shape, the shift fork sleeve is prevented from rotating when the shift fork plate rotates, thereby achieving the anti-rotation function.

[0028] In one embodiment, the shift fork 11 includes multiple fork tines 111, which are fixedly connected to the slip-ring rotor end 1. The coordinated connection of multiple shift forks 11 further enhances connection stability. To prevent backlash between the rotating shaft 2 and the slip-ring rotor end 1 due to gaps, multiple shift forks 11 are connected to the fork plate 21. This significantly reduces the rotational angle error between the rotating shaft 2 and the slip-ring rotor end 1 during alternating forward and reverse rotation. In this embodiment, the number of shift forks 11 is preferably two.

[0029] In one embodiment, a plurality of shift fork teeth 111 are distributed at intervals along the circumference of the conductive slip ring rotor end 1 .

[0030] In one embodiment, the cross section of the shift fork teeth 111 is rectangular. The rectangular shape prevents the shift fork from rotating when the shift fork plate rotates, thereby achieving an anti-rotation function.

[0031] In one embodiment, the fork plate 21 further defines a central hole 212 , and the mounting hole 211 is communicated with the central hole 212 .

[0032] In one embodiment, the width of the gap between the fork sleeve 3 and the fork disc 21 is 0-0.05 mm, and / or the width of the gap between the fork 11 and the inner wall of the mounting cavity 31 is 0-0.05 mm.

[0033] In one embodiment, the material of the fork plate 21 is polytetrafluoroethylene.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
