[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 6 As shown, a self-lubricating sealing ring provided by an embodiment of the utility model includes a sealing ring body 1, a slow-release member for absorbing and storing lubricating oil is placed inside the sealing ring body 1, the slow-release member includes a first slow-release member 3, the main body of the first slow-release member 3 is located inside the sealing ring body 1, the oil-releasing part of the slow-release member extends through the sealing ring body 1 to the outside, and the sealing ring body 1 cooperates with the first slow-release member 3 to release oil and perform self-lubricating action.

[0026] The above-mentioned self-lubricating sealing ring has a structure designed inside the slow-release part that can absorb and store lubricating oil. The lubricating oil is slowly released during the use of the first slow-release part 3, so even if it is used for a long time, the contact part between the shaft body and the sealing ring can be kept well lubricated. Specifically, with the friction of the sealing ring during operation, the lubricating oil in the first slow-release part 3 will gradually be released onto the contact surface, replenishing and maintaining the lubrication effect, thereby extending the service life of the sealing ring and the shaft body. Compared with traditional sealing rings that require external lubricant replenishment, the design of this self-lubricating sealing ring reduces the frequency of use of external lubricants, thereby reducing maintenance costs and operating risks caused by lubricant loss.

[0027] In this embodiment, a guide arc surface 2 for installing the sealing ring body 1 is provided on one side of the sealing ring body 1. A first placement groove 4 is provided inside the sealing ring body 1, and a first slow-release member 3 is placed inside the first placement groove 4. The shape of the first slow-release member 3 is consistent with the first placement box. The first slow-release member 3 includes a storage ring 301, which is placed inside the first placement groove 4, and a release ring 302 is fixedly connected to the outside of the storage ring 301.

[0028] The sealing ring body 1 has a guide arc surface 2 for ensuring the correct installation and positioning of the sealing ring. The storage ring 301 is placed in the first placement groove 4 for absorbing and storing lubricating oil. Its design ensures a lasting lubricating effect, and even after long-term use, it can still release enough lubricating oil to maintain the sealing effect. The release ring 302 is fixedly connected to the outside of the storage ring 301, and its width is smaller than the storage ring 301. This design enables the release ring 302 to gradually release the lubricating oil in the storage ring 301 to the surface of the sealing ring in contact with the shaft during use, thereby achieving a slow and continuous self-lubricating effect.

[0029] The storage ring 301 absorbs and stores lubricating oil and releases it to the contact surface between the seal ring and the shaft when needed. The small width design of the release ring 302 helps to control the release speed, ensuring that the lubricating oil can be continuously replenished to the friction interface, thereby reducing friction and wear.

[0030] Long-lasting lubrication effect: Compared with the traditional method of adding lubricant regularly, this self-lubricating seal ring can maintain a stable lubrication effect for a long time through the precise design of the internal structure, thereby improving the service life and reliability of the seal ring.

[0031] In another embodiment, the slow-release member includes a second slow-release member 6, which is arranged inside the sealing ring body 1, and the sealing ring body 1 is cast outside the second slow-release member 6. The second slow-release member 6 includes an arc storage plate 601, and a plurality of arc storage plates 601 are provided. The plurality of arc storage plates 601 are arranged in a circumferential array inside the sealing ring body 1, and an arc guide rod 603 is fixedly connected between two adjacent arc storage plates 601, and an arc release plate 602 is fixedly connected outside the arc storage plate 601, and the arc release plate 602 is communicated with the outside, and the sealing ring body 1 is formed with a second placement groove 5 that matches the shape of the second slow-release member 6, and the second slow-release member 6 is located in the second placement groove 5.

[0032] The arc storage plates 601 are arranged in a circumferential array inside the seal ring body 1 and are fixedly connected by arc guide rods 603, ensuring the stable position and spacing of the storage plates. This layout allows the lubricating oil to be evenly distributed in the entire seal ring and shaft contact area, reducing the problem of insufficient or excessive lubrication.

[0033] Appropriate release: The arc-shaped release plate 602 is connected to the outside world. Through the design of the internal structure, the size and number of the openings of the release plate can be controlled to adjust the release rate of the lubricating oil. The function of the release plate is to ensure that the lubricating oil is released to the contact surface at an appropriate speed, thereby maintaining a good lubrication state of the friction interface.

[0034] Long-term stability: The close combination and molding method of the sealing ring body 1 and the second slow-release member 6 ensure the stability and durability of the overall structure. This design can not only provide good lubrication effect in the short term, but also maintain stable performance in the long term, extending the service life of the sealing ring and the shaft.

[0035] The working principle of this utility model:

[0036] When in use, the structure designed inside the slow-release member can absorb and store lubricating oil. The lubricating oil is slowly released during the use of the first slow-release member 3, so even if it is used for a long time, the contact part between the shaft body and the sealing ring can be kept well lubricated. Specifically, with the friction of the sealing ring during operation, the lubricating oil in the first slow-release member 3 will gradually be released onto the contact surface, replenishing and maintaining the lubrication effect, thereby extending the service life of the sealing ring and the shaft body. Compared with the traditional sealing ring that requires external lubricant replenishment, the design of this self-lubricating sealing ring reduces the frequency of use of external lubricants, thereby reducing the maintenance cost and operation risk caused by lubricant loss.
