Description

Technical Field

[0001] This utility model relates to the technical field of bearing parts, and to an improved bearing rubber seal ring. Background Technology

[0002] Application number CN200520039201.9 discloses a bearing seal, particularly a ball bearing seal ring. The ball bearing seal ring has two circular protrusions extending upwards from one end face of a ring. The inner diameter of the smaller diameter protrusion matches the outer diameter of the inner ring of the ball bearing, and the larger diameter protrusion matches the outer diameter of the ball ring. The inner diameter of the seal ring is not smaller than the inner diameter of the inner ring of the ball bearing. It features the advantages of preventing grease ignition, avoiding frequent lubrication, and having a simple structure. It is widely used in bearings.

[0003] In the aforementioned practical example, although the ball bearing seal ring has two circular protrusions extending upwards from one end face of a ring, with the inner diameter of the smaller protrusion matching the outer diameter of the inner ring of the ball bearing, and the larger protrusion matching the outer diameter of the ball ring, and the inner diameter of the seal ring being no smaller than the inner diameter of the inner ring of the ball bearing, achieving characteristics such as preventing grease fires, avoiding frequent lubrication, and having a simple structure, a drawback is that the bearing seal ring, being made of rubber, is susceptible to deformation, leading to a shorter service life. Therefore, it is necessary to add a metal seal ring to the device. The rigidity of the metal seal ring makes it less prone to deformation, allowing for longer use and greater durability.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 As shown, this utility model is an improved bearing rubber seal ring, including a seal ring body 1, a seal ring outer ring 2, a seal ring inner ring 3, and a metal sealing ring 4. The seal ring inner ring 3 is fixedly disposed inside the seal ring body 1, the seal ring outer ring 2 is fixedly disposed outside the seal ring body 1, and the metal sealing ring 4 is fixedly installed at the bottom of the seal ring inner ring 3.

[0026] The sealing ring body 1 contains a ring body 101. Several suction cup ports 102 are fixedly installed at the bottom of the ring body 101. Several sound-absorbing ports 103 are fixedly opened on the inner wall of the ring body 101. A common cavity 104 is fixedly opened inside the several sound-absorbing ports 103. Sound-absorbing cotton 105 is fixedly installed inside the cavity 104.

[0027] The outer ring 2 of the sealing ring contains a second ring body 201. A limiting groove 202 is fixedly opened on the outer side of the second ring body 201. The limiting groove 202 is semi-circular.

[0028] The inner ring 3 of the sealing ring contains a ring body 301. The bottom of the ring body 301 is fixedly connected to an extension fixing ring 302. The bottom of the extension fixing ring 302 is fixedly connected to a fixing ring 303. A ring spring 304 is movably arranged in the middle of the extension fixing ring 302. A metal sealing ring 4 is movably installed at the bottom of the ring spring 304.

[0029] The metal sealing ring 4 is movably installed inside the extension fixing ring 302 and is of a suitable size. The diameter of the fixing ring 303 is smaller than that of the metal sealing ring 4.

[0030] The sealing ring body 1, the outer ring 2, and the inner ring 3 are all fixedly connected.

[0031] Working principle: When using this bearing seal ring, the limiting groove 202 on the outer ring 2 of the seal ring corresponds to the limiting block inside the bearing, which can provide a good fixing effect. At the same time, the suction port 102 at the bottom of the seal ring body 1 has a certain adsorption capacity, providing firmness. The inner ring 3 of the seal ring rotates together with the metal sealing ring 4, and the metal sealing ring 4 provides a good sealing effect and shaping support effect. The annular ring 304 on the extension fixing ring 302 has a good contraction effect. During operation, some noise will be generated. At this time, the sound absorption port 103 on the inner side of the seal ring body 1 and the sound absorption cotton 105 inside will absorb the noise, thus avoiding noise generation.
