[0060] Embodiment 1

[0061] As shown in the accompanying Figures 1-5 ​As shown in the drawings, the embodiment discloses a bearing assembly with a hydrophobic ring, which is used for reducing the wear degree between a rotating shaft 2 and a sliding bearing 1, and mainly comprises the sliding bearing 1, a bearing seat 3, the rotating shaft 2 and the hydrophobic ring 5. In use, workers inject cleaning water into the sliding bearing 1 through a water inlet 6; when the rotating shaft 2 rotates relative to the sliding bearing 1, the cleaning water and waste residues in the sliding bearing 1 can rotate together; then, under the action of the hydrophobic ring 5, the waste residues accumulated in a mounting chamber 34 can be flushed away from a water outlet 33, so that the waste residues can be prevented from entering the area where the rotating shaft 2 contacts the sliding bearing 1, and the wear degree between the rotating shaft 2 and the sliding bearing 1 is reduced.

[0062] The specific structure of the bearing assembly is as follows: the bearing assembly comprises the bearing seat 3, the sliding bearing 1 is arranged in the bearing seat 3, the rotating shaft 2 is rotatably arranged in the sliding bearing 1, one end of the rotating shaft 2 extends away from the bearing seat 3, the mounting chamber 34 is arranged between the outer wall of the rotating shaft 2 and the inner wall of the bearing seat 3, the hydrophobic ring 5 is arranged in the mounting chamber 34, the water inlet 6 is arranged in the end wall of the sliding bearing 1, and the water outlet 33 is arranged on the peripheral wall of the bearing seat 3. Compared with the prior art, the bearing assembly can reduce the wear degree between the rotating shaft 2 and the sliding bearing 1, thereby prolonging the service life of the sliding bearing 1, and therefore, the bearing assembly has high practicability.

[0063] Further, as shown in the drawings, Figure 4 or the drawings, Figure 5 As shown, a plurality of hydrophobic holes 52 are arranged in the peripheral wall of the hydrophobic ring 5, and the design can improve the flushing effect of the cleaning water on the waste residues.

[0064] In a specific application scenario, as shown in the drawings, Figure 4 and the drawings, Figure 5 As shown, a first annular groove 51 is arranged in the peripheral wall of the hydrophobic ring 5, and the hydrophobic holes 52 are arranged in the first annular groove 51, and the design can improve the flushing effect of the cleaning water on the waste residues; in addition, a second annular groove 53 is arranged in the inner peripheral wall of the hydrophobic ring 5, and the hydrophobic holes 52 are arranged in the second annular groove 53, and the design can improve the flushing effect of the cleaning water on the waste residues.

[0065] In a specific application scenario, as shown in the drawings, Figure 1 or the drawings, Figure 2 As shown, an auxiliary water inlet 32 is arranged in the peripheral wall of the bearing seat 3 close to the mounting chamber 34, the auxiliary water inlet 32 is communicated with the hydrophobic holes 52, and the auxiliary water inlet 32 is arranged in the bearing seat 3 in a spaced manner with the water outlet 33. In use, workers can inject cleaning water from the water inlet 6 and the auxiliary water inlet 32, so that the sliding bearing 1 can carry more cleaning water at the same time, and the flushing effect is improved to a certain extent.

[0066] Furthermore, the auxiliary inlet 32 ​​is provided with a discharge end (not marked in the figure), and the drainage hole 52 is provided with a feed end (not marked in the figure). The discharge end of the auxiliary inlet 32 ​​is opposite to the feed end of the drainage hole 52. This design can improve the efficiency of water injection by the staff through the auxiliary inlet 32. The outlet 33 is provided with a feed end (not marked in the figure), and the drainage hole 52 is provided with a discharge end (not marked in the figure). The feed end of the outlet 33 is opposite to the discharge end of the drainage hole 52. This design can improve the efficiency of waste residue discharge. Normally, the inner diameter of the auxiliary inlet 32 ​​is smaller than the inner diameter of the inlet 6. If the inner diameter of the auxiliary inlet 32 ​​is smaller, it can enhance the impact force of the local water flow, which can improve the flushing effect of the waste residue in this embodiment to a certain extent. In addition, the auxiliary inlet 32 ​​is inclined, which can enhance the effect of directional flushing and turbulent disturbance; the outlet 33 is inclined, which is conducive to the smooth discharge of waste residue.

[0068] Furthermore, the sealing component 4 mainly includes a first packing 41 and a second packing 42. Specifically, the first packing 41 is located on the side of the hydrophobic ring 5 away from the sliding bearing 1, and is wound around the inner wall of the mounting chamber 34.

The second packing 42 is provided on the side of the hydrophobic ring 5 close to the sliding bearing 1, and is wound around the inner wall of the mounting chamber 34. The second packing 42 can store some of the waste residue entering the contact area between the rotating shaft 2 and the sliding bearing 1 from the outside. In use, the combination of the first packing 41 and the second packing 42 can reduce the wear between the rotating shaft 2 and the sliding bearing 1. In addition, under the action of the rotating shaft 2 and the hydrophobic ring 5, the waste residue in the first packing 41 and the second packing 42 is continuously flushed away from the outlet 33.

[0069] Furthermore, the sealing component 4 can be acid and alkali resistant packing. This design can resist corrosive substances, ensure the reliability of the seal, and extend the service life of the sealing component 4 to a certain extent. In addition, the sealing component 4 can be 16*16mm packing. This design improves the reliability of the sealing component 4, thereby effectively preventing external waste from entering the area where the rotating shaft 2 contacts the sliding bearing 1.

A water storage chamber 31 is arranged between the end of the rotating shaft 2 and the end wall of the sliding bearing 1, and the water storage chamber 31 is located in the downstream direction of the water inlet 6. Such a design can make the accumulated cleaning water form a pulse water flow, thereby enhancing the washing effect of the waste residue and stabilizing the pressure of the overall structure of the embodiment to a certain extent.

A water storage chamber 31 is arranged between the end of the rotating shaft 2 and the end wall of the sliding bearing 1, and the water storage chamber 31 is located in the downstream direction of the water inlet 6. Such a design can make the accumulated cleaning water form a pulse water flow, thereby enhancing the washing effect of the waste residue and stabilizing the pressure of the overall structure of the embodiment to a certain extent. Figure 2 In addition, the space inside the bearing seat 3 can be generally divided into a first space 35 and a second space 36. The first space 35 is located in the downstream direction of the water inlet 6, and the second space 36 is located in the downstream direction of the first space 35. The mounting chamber 34 is arranged in the second space 36, and the inner diameter of the first space 35 is greater than the inner diameter of the second space 36. Such a design can enhance the local flushing force, thereby improving the overall washing effect.

[0071] Generally, as shown in Fig. 3, mounting holes (not marked in the figure) are formed on the right side of the bearing seat 3, on the left side of the bearing seat 3 close to the sliding bearing 1, and on the left side of the sliding bearing 1 close to the bearing seat 3.
