Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, and in particular to a waterproof bearing assembly with high sealing performance. Background Art
[0002] Bearings are key components used to support rotating or moving parts in machinery. They reduce friction, support loads, and ensure smooth operation. There are many types of bearings, depending on the application and requirements.
[0003] In existing technologies, waterproof bearing assemblies mostly use a single sealing structure or rely on chemical sealing materials to prevent liquid infiltration. However, these designs often appear to be inadequate when faced with complex or changing working environments. When bearings are exposed to high humidity or direct contact with liquid, liquid may penetrate through tiny gaps or weak seals inside the bearing, thereby affecting the lubrication effect of the bearing and causing accelerated wear of the bearing. At the same time, since traditional sealing materials may age or deform after long-term use, the sealing effect is further reduced. In addition, these designs usually lack multiple protection mechanisms and cannot effectively disperse the paths of liquid entry, increasing the risk of liquid leakage. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and provide a waterproof bearing assembly with high sealing performance.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a highly sealed waterproof bearing assembly, comprising: a concave ring, the inner wall of the concave ring is provided with a convex ring, the inner wall of the concave ring and the outer side of the convex ring fit together, the top side of the convex ring is provided with a protective cover, the top side of the convex ring is in contact with the inner side of the protective cover, the bottom side of the concave ring is provided with an inner ring, the bottom side of the concave ring is respectively provided with an inner ring and an outer ring, and the bottom side of the concave ring is in contact with one side of the inner ring and the outer ring.
[0006] As a preferred embodiment, a sponge pad is provided on the inner surface of the concave ring, the inner surface of the concave ring is fitted and fixed with the outer side of the sponge pad, and the top side of the sponge pad is in contact with the bottom side of the convex ring.
[0007] As a preferred embodiment, a positioning hole is opened on one side of the inner ring, a fixing member 1 is provided on the inner surface of the positioning hole, and the inner surface of the positioning hole is threadedly connected to one end of the fixing member 1.
[0008] As a preferred embodiment, one end of the fixing member is connected through the inner surface of the concave ring, and the top side of the concave ring is in contact with the inner side of the protective cover.
[0009] As a preferred embodiment, the inner surface of the protective cover is threadedly connected to the outer surface of the first fixing member.
[0010] As a preferred embodiment, a filling port is opened on one side of the inner ring, and the one side of the inner ring corresponds to the inner surface of the filling port.
[0011] As a preferred embodiment, a heat dissipation hole is opened on the inner side of the inner ring, a second fixing member is provided on the inner surface of the heat dissipation hole, and the inner surface of the heat dissipation hole is threadedly connected to the outer side of the second fixing member.
[0012] As a preferred embodiment, the outer side of the convex ring is movably connected to the inner side of the outer ring.
[0013] Compared with the prior art, the advantages and positive effects of the present invention are:
[0014] 1. When liquid enters between the concave ring and the convex ring, due to the many tortuous paths between the two, the liquid will be affected by multiple changes in direction during the flow process, thereby slowing down its flow rate. This helps prevent the liquid from passing through the connection quickly and reduces the risk of leakage. The design between the concave ring and the convex ring forms a mechanical structure that can effectively resist the intrusion of liquid and enhance the overall sealing performance. This sealing performance can effectively prevent external liquid from invading the interior of the bearing and protect its normal operation;
[0015] 2. The protective covers designed on the top sides of the convex and concave rings can effectively prevent direct contact between the convex and concave rings and reduce the risk of failure caused by environmental factors. When the convex and concave rings need to be removed from one side of the outer and inner rings, the fixings in the protective cover are separated from the inner ring, so that the protective cover, concave ring and convex ring are simultaneously released. Then, a filling port is designed on the inner ring to add lubricant as needed, simplifying the removal process of the fixings.
[0016] 3. There are heat dissipation holes on the inner side of the inner ring. When the bearing temperature in the inner ring and the outer ring is too high, the high temperature may cause the lubricant to degrade or fail. By effectively dissipating heat, the performance of the lubricant can be maintained and wear caused by insufficient lubrication can be prevented. Remove the second fixing part in the heat dissipation hole from the inner wall. The heat dissipation hole can quickly release heat and reduce the operating temperature of the bearing.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Example 1
[0025] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a highly sealed waterproof bearing assembly, comprising: a concave ring 13, an inner wall of the concave ring 13 is provided with a convex ring 15, the inner wall of the concave ring 13 and the outer side of the convex ring 15 fit together, a top side of the convex ring 15 is provided with a protective cover 16, the top side of the convex ring 15 contacts the inner side of the protective cover 16, an inner ring 12 is provided on the bottom side of the concave ring 13, the inner ring 12 and the outer ring 11 are respectively provided on the bottom side of the concave ring 13, the bottom side of the concave ring 13 and one side of the inner ring 12 and the outer ring 11, the inner surface of the concave ring 13 is provided with a sponge pad 14, the inner surface of the concave ring 13 It fits and is fixed with the outer side of the sponge pad 14, the top side of the sponge pad 14 is in contact with the bottom side of the convex ring 15, a positioning hole 18 is provided on one side of the inner ring 12, and a fixing part 17 is provided on the inner surface of the positioning hole 18, the inner surface of the positioning hole 18 is threadedly connected to one end of the fixing part 17, and one end of the fixing part 17 is connected through the inner surface of the concave ring 13, the top side of the concave ring 13 is in contact with the inner side of the protective cover 16, and the inner surface of the protective cover 16 is threadedly connected to the outer side of the fixing part 17, a filling port 19 is provided on one side of the inner ring 12, and one side of the inner ring 12 corresponds to the inner surface of the filling port 19.
[0026] In this embodiment, when this type of highly sealed waterproof bearing assembly is in use, the inner ring 12 is embedded in the outer ring 11. After the two are connected, an annular gap is formed at the joint. Therefore, a concave ring 13 is provided on one side of the gap, and a convex ring 15 is provided corresponding to the concave ring 13. When liquid enters between the concave ring 13 and the convex ring 15, due to the large number of tortuous paths between the two, the liquid is affected by multiple changes in direction during the flow process, thereby slowing its flow rate. This helps prevent the liquid from quickly passing through the joint and reduces the risk of leakage. The design between the concave ring 13 and the convex ring 15 forms a mechanical structure that can effectively resist the intrusion of liquid and enhance the overall sealing performance. This sealing performance can effectively prevent external liquid from invading the interior of the bearing and protect its normal operation. In addition, a sponge pad 14 is designed in the concave ring 13. The softness and elasticity of the sponge pad 14 can fully fill the tiny gap between the concave ring 13 and the outer ring 11, preventing liquid from leaking through the gap. This provides a better sealing effect, ensures the dryness of the bearing interior, and avoids the intrusion of liquids or contaminants.
[0027] Secondly, by designing the protective cover 16 on the top side of the convex ring 15 and the concave ring 13, the liquid can be effectively prevented from directly contacting the convex ring 15 and the concave ring 13, thereby reducing the risk of failure caused by environmental factors. In addition, when the convex ring 15 and the concave ring 13 need to be removed from one side of the outer ring 11 and the inner ring 12, the fixing part 17 in the protective cover 16 is separated from the inner ring 12, so that the protective cover 16, the concave ring 13 and the convex ring 15 are fixed and released at the same time. Then, a filling port 19 is designed on the inner ring 12, and lubricating liquid can be added to the inside as needed. By simplifying the release process of the fixing parts, the protective cover 16, the concave ring 13 and the convex ring 15 can be quickly disassembled, which is convenient for technicians to inspect, clean and repair, reducing maintenance time and improving work efficiency. In addition, the protective cover 16 is combined with the filling port 19 to improve the compactness and aesthetics of the overall design, making the equipment look more neat and professional.
[0028] Example 2
[0029] like Figure 4 As shown, a heat dissipation hole 110 is opened on the inner side of the inner ring 12, and a second fixing part 111 is provided on the inner surface of the heat dissipation hole 110. The inner surface of the heat dissipation hole 110 is threadedly connected to the outer side of the second fixing part 111, and the outer side of the convex ring 15 is movably connected to the inner side of the outer ring 11.
[0030] In this embodiment, a heat dissipation hole 110 is opened on the inner side of the inner ring 12. When the bearing temperature in the inner ring 12 and the outer ring 11 is too high, the excessively high temperature may cause the lubricant to degrade or fail. By effectively dissipating heat, the performance of the lubricant can be maintained and wear caused by insufficient lubrication can be prevented. The second fixing part 111 in the heat dissipation hole 110 is removed from the inner wall. The heat dissipation hole 110 can quickly release heat and reduce the operating temperature of the bearing, thereby preventing equipment damage and performance degradation caused by overheating. At the same time, the design of the heat dissipation hole 110 enables the equipment to flexibly respond to temperature changes under different working conditions, which is particularly suitable for high-load or high-temperature working environments.
[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
