[0022] The utility model provides a water-leakage-proof and highly sealed bearing seat casting for a washing machine, comprising a rotating shaft 101, a bearing 102 and a sealing assembly 103, wherein the sealing assembly 103 comprises a bearing seat 104, an end cover 105, a sealing ring 106, a water retaining ring 107, a spring sheet 108 and a water retaining seat 113, wherein the water retaining ring 107 has a sealing protrusion 109 and a first limiting protrusion 110, and the rotating shaft 101 has a first limiting groove 111 and a second limiting groove 112, wherein a two-layer sealing structure is formed by the sealing ring 106 and the water retaining ring 107, wherein the spring sheet 108 provides elasticity to the sealing ring 106 to enhance the sealing effect of the sealing ring 106, and the water retaining ring 107 further blocks the water flow, thereby enhancing the sealing effect. It can be understood that the aforementioned scheme can be used to enhance the sealing effect of the bearing 102, and can also be used to enhance the water retaining effect of the water retaining ring 107.

[0023] According to this specific embodiment, the bearing 102 is rotatably mounted on the rotating shaft 101 , and the bearing 102 includes an inner ring, an outer ring, and balls, wherein the inner ring is fixedly mounted on the rotating shaft 101 , and the outer ring is fixedly mounted inside the bearing seat 104 .

[0024] The bearing seat 104 is connected to the bearing 102 and is sleeved on the bearing 102. The end cover 105 is fixedly connected to the bearing seat 104 and is located on one side of the bearing seat 104. The sealing ring 106 is connected to the bearing seat 104, abuts against the rotating shaft 101, and is arranged on the bearing seat 104. The water retaining ring 107 is connected to the sealing ring 106 and is located on one side of the sealing ring 106. The spring sheet 108 is connected to the sealing ring 106 and is arranged on the sealing ring 106. The end cover 105 is fixedly connected to the bearing seat 104 by bolts. Two groups of sealing rings 106 and water retaining rings 107 are provided. The other group of sealing rings 106 and water retaining rings 107 are provided on the end cover 105, so as to seal the bearing seat 104 and the bearing 102 inside the end cover 105. A plurality of The spring sheet 108 provides elasticity to the sealing ring 106 through the spring sheet 108, so that the sealing ring 106 is pressed against the rotating shaft 101, and at the same time, the sealing ring 106 is prevented from reducing the sealing effect due to wear and deformation. The water retaining ring 107 is C-shaped. When the bearing seat 104 and the end cover 105 are installed in place, the sealing ring 106 and the water retaining ring 107 are pressed against the rotating shaft 101, so as to waterproof the bearing 102. Two layers of sealing are formed by the sealing ring 106 and the water retaining ring 107. Through the shape of the water retaining ring 107, when the water flow impacts the water retaining ring 107, the water retaining ring 107 will be deformed under the action of water pressure, and then one end of the water retaining ring 107 is pressed against the rotating shaft 101, thereby further improving the anti-leakage effect, realizing the improvement of the sealing effect of the bearing seat 104 and the end cover 105, and avoiding the problem of rust damage to the bearing 102.

[0025] Secondly, the sealing protrusion 109 is arranged on the water retaining ring 107 and is located on the side of the water retaining ring 107 close to the rotating shaft 101; when the water retaining ring 107 is deformed under the action of water pressure, the sealing protrusion 109 can abut against the rotating shaft 101, thereby improving the water retaining effect of the water retaining ring 107; at the same time, when the water retaining ring 107 is not subjected to external force, the sealing protrusion 109 is away from the rotating shaft 101 to avoid wear of the sealing protrusion 109.

[0026] At the same time, the first limiting protrusion 110 is arranged on the water retaining ring 107 and is located on the side of the water retaining ring 107 close to the rotating shaft 101; the first limiting groove 111 is arranged on the rotating shaft 101 and is located on the side of the rotating shaft 101 close to the first limiting protrusion 110, and the first limiting groove 111 cooperates with the first limiting protrusion 110; the second limiting groove 112 is arranged on the rotating shaft 101 and is located on the side of the rotating shaft 101 close to the sealing ring 106; the first limiting protrusion 110 is located inside the first limiting groove 111, and the first limiting protrusion 110 is limited by the first limiting groove 111, and then the water retaining ring 107 is limited to avoid the water retaining ring 107 from deviating and affecting the water retaining effect; the end of the sealing ring 106 is located inside the second limiting groove 112, and the sealing ring 106 is limited by the second limiting groove 112 to avoid the sealing ring 106 from deviating and affecting the sealing effect.

[0027] In addition, the water retaining seat 113 is fixedly connected to the bearing seat 104 and is arranged on the bearing seat 104; the water retaining seat 113 blocks the water flow, reduces the impact force of the water flow hitting the water retaining seat 113, and prevents the water retaining ring 107 from being unable to effectively block the water flow when the impact is large.

[0028] When the water-leakage-proof and highly sealed washing machine bearing seat casting of this embodiment is used, the sealing ring 106 is pressed against the rotating shaft 101 by the elasticity of the spring sheet 108, thereby forming a first-layer sealing structure, and a second-layer sealing structure is formed by the water retaining ring 107. When the water flow impacts the water retaining ring 107, the water retaining ring 107 is deformed, thereby driving the sealing protrusion 109 to abut against the rotating shaft 101, thereby improving the sealing effect of the water retaining ring 107, thereby improving the sealing effect of the bearing seat 104 and the end cover 105, and avoiding the problem of rust and damage of the bearing 102.

[0029] Second embodiment:

[0030] Based on the first embodiment, please refer to Figure 5 , Figure 5 2 is a schematic diagram of the structure of the oil filling hole of the second embodiment. The bearing seat 104 of this embodiment has an oil filling hole 201 and a sealing column 202.
