Description

Technical Field

[0001] The utility model relates to the technical field of floating seal equipment, in particular to a thin floating seal ring. Background Technique

[0002] The thin floating seal ring technology is a high-performance sealing technology, which is widely used in various industrial fields. The floating seal was initially used in crawler walking machinery. Due to its excellent sealing performance, long service life and strong adaptability, it has been widely used in engineering machinery, coal mining machinery and other fields later. The main structures of the floating seal are divided into two types: the O-shaped structure seal and the variant diamond-shaped structure elastomer seal. They are both composed of two rubber rings and two floating metal seal rings, which are respectively installed in two sealing cavities. Its sealing mechanism is based on two relatively sliding metal seal rings, and the sealing is achieved under the axial pressure generated by the compression of the elastomer. The contact surface of the seal ring is precisely machined to form a wedge-shaped oil gap, which ensures sufficient lubrication and forms an extremely thin oil film. This oil film plays a role in balancing the internal and external pressure differences, preventing leakage and external pollution. Although the thin floating seal ring has many advantages, there are still some defects and limitations in the existing technology. Under working conditions of high speed, high pressure or containing hard particles, the wear problem of the thin floating seal ring may be relatively serious, which will shorten its service life. The installation of the thin floating seal ring requires high precision. If the installation is improper, it may lead to poor sealing or early failure. Although the designed service life of the floating seal ring is relatively long, once it needs to be replaced, it may require a complex disassembly and installation process, increasing the maintenance cost and time. In some dynamic applications, the floating seal ring may be affected by vibration and impact, which may affect its sealing performance and stability. The thin floating seal ring technology is a key and continuously developing engineering technology, which is of great significance for ensuring the reliability and efficiency of mechanical equipment.

[0003] The patent with the application number CN209511107U discloses a floating seal ring, a labyrinth floating seal ring, including a labyrinth floating seal ring body. Four labyrinth grooves are dug at the inner end of the labyrinth floating seal ring body. A receiving groove is dug at the outer end of the labyrinth floating seal ring body. A fastening spring is movably connected in the receiving groove. Return grooves are dug at both the upper and lower ends of the labyrinth floating seal ring body. The return grooves are all interconnected with the four labyrinth grooves. An auxiliary positioning block is fixedly connected to the upper end of the labyrinth floating seal ring body. A plurality of positioning grooves are dug at the outer end of the labyrinth floating seal ring body. The positioning grooves match the auxiliary positioning block. A limiting block is arranged at the outer end of the labyrinth floating seal ring body. However, this device has problems of inconvenient installation and poor floating sealing effect. Therefore, in order to facilitate installation and improve the floating and sealing performance of the device, the utility model provides a thin floating seal ring. Summary of the Utility Model

A spring 7 is provided inside the fixing clip arms 5. The spring 7 is installed in the inner card slots of the fixing clip arms 5. Mounting holes 12 are provided on both sides of the device housing 11.

[0020] In this embodiment:

[0021] The working process of this device is as follows: When the device needs to be installed, first put the device housing 11 above the bearing and push the device housing 11 to a proper position. Place two semi-circular bases 1 inside the device housing 11. The semi-circular bases 1 are symmetrically arranged on both sides of the bearing. The semi-circular bases 1 arranged on both sides of the bearing are spliced with each other and sleeved on a proper position of the bearing. An internal groove 10 is provided inside the semi-circular base 1, and a rubber pad 2 is fixedly installed on the internal groove 10. The rubber pad 2 can achieve a floating sealing effect when the bearing rotates, which not only prevents the lubricant from flowing into the device through the floating seal ring, but also ensures that the floating generated by the rotation of the bearing will not damage the sealing effect. An external groove 13 is provided outside the semi-circular base 1, and a buckle structure 8 is provided above the external groove 13. The buckle structures 8 provided on the semi-circular bases 1 on both sides of the bearing are spliced with each other, so that the base device is sleeved on a proper position above the bearing. A buckle fixing clip 9 is provided above the buckle structure 8. The buckle fixing clip 9 includes: a fixing clip arm 5, a rotating bearing 6, and a spring 7. A rotating bearing 6 is provided above the fixing clip arm 5. The rotating bearing 6 penetrates through the circular hole above the fixing clip arm 5. The rotating bearing 6 can connect the two fixing clip arms 5. The rotating bearing 6 penetrates into the circular holes above the two fixing clip arms 5 to form a clamping structure. A spring 7 is provided inside the fixing clip arm 5. The spring 7 is installed in the inner groove of the fixing clip arm 5. The spring 7 can tighten the clamping structure formed by the fixing clip arm 5, so that the buckle fixing clip 9 plays a fixing role. The buckle fixing clip 9 can be connected to the buckle structure 8 provided on the semi-circular base 1. The buckle fixing clip 9 and the buckle structure 8 are engaged with each other, which not only fixes the two buckle structures 8 to ensure the sealing performance of the device, but also plays an effect of facilitating installation. After the two semi-circular bases 1 provided on the bearing are fixedly installed, a tightening spring 3 is sleeved above the external groove 13. Connecting groove structures 4 are provided on both sides of the tightening spring 3. The connecting groove structures 4 are fixedly arranged at the disconnection points on both sides of the tightening spring 3. Both sides of the connecting groove structure 4 are connected to the spring break points. The connecting groove structure 4 can be installed above the buckle fixing clip 9, so that the tightening spring 3 plays a tightening role on the device. When the bearing rotates and generates vibrations, the tightening spring 3 can achieve a floating effect and offset the vibrations in time to prevent affecting the normal operation of the device. After the installation of the tightening spring 3 is completed, the device housing 11 is sleeved above the bearing, spliced with the inner device housing 11, and wraps the internal structure, so that this floating seal ring can better achieve the sealing effect and the floating effect. Installation holes 12 are provided on both sides of the device housing 11. Through the installation holes 12, this floating seal ring can be fixedly installed on the equipment to be sealed, better achieving the floating effect and the sealing effect, and thus enabling the equipment to operate better.
