Description

Technical Field

[0001] This utility model relates to the field of bearing sealing technology, specifically to a rubber sealing ring for bearings. Background Technology

[0002] Bearings are components that fix and reduce the coefficient of friction of loads during mechanical transmission. In other words, they are components used to reduce the coefficient of friction during power transmission and maintain the fixed position of the shaft's center when other machine parts move relative to each other on the shaft. Bearings are crucial components in modern mechanical equipment; their main function is to support rotating mechanical parts and reduce the coefficient of friction of mechanical loads during transmission. Bearings are widely used mechanical components; whether in airplanes, automobiles, ships, machine tools, motors, or household appliances, wherever there is a rotating support, bearings are indispensable.

[0003] Currently, after a long period of time, the sealing performance of bearing seals is affected by the long-term friction between the seal and the inside of the bearing, which reduces the sealing effect on the bearing. Therefore, it is necessary to design a rubber seal for bearings to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rubber seal ring for bearings to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A rubber seal for a bearing, comprising: The bearing body has two spacer rings fixedly connected to the outer wall of its inner ring, and the outer wall of the spacer rings has a placement groove. A sealing ring is fixedly connected inside the placement groove, and an adjustment groove is provided at one end of the sealing ring; An elastic ring is disposed inside the adjusting groove; A positioning component is disposed inside the adjustment groove and is used to position the elastic ring piece.

[0006] Preferably, the positioning component includes: a connecting ring, the connecting ring being fixedly connected inside the adjusting groove, one end of the connecting ring having a connecting groove, and the elastic ring being movably sleeved with the connecting groove.

[0007] Preferably, one end of the elastic ring is fixedly connected to a fixing ring, and the fixing ring is movably installed together with the adjusting groove.

[0008] Preferably, a retaining ring is provided inside the bearing body, and a first sealing ring is fixedly connected to the outer wall surface of the retaining ring.

[0009] Preferably, a second sealing ring is fixedly connected to the inner wall surface of the blocking ring, and a plurality of anti-slip grooves are provided at one end of the blocking ring.

[0010] Preferably, a mounting groove is provided on one side of the partition ring, and a mounting ring is fixedly connected to one end of the blocking ring, with the mounting ring threadedly connected to the mounting groove.

[0011] In the above technical solution, the bearing rubber sealing ring provided by this utility model has the following advantages: By setting up the bearing body, after the operator fixes the sealing ring inside the placement groove, the positioning component is used to position the elastic ring plate, so that the elastic ring plate can be fixed inside the adjustment groove. At this time, the elastic force released by the elastic ring plate can squeeze the sealing ring, so that the sealing ring can tightly seal between the spacer ring and the outer ring of the bearing body, thereby preventing the lubricating oil inside the bearing body from flowing out or being contaminated by the outside. At the same time, when the sealing ring wears out after long-term use, the elastic force continuously released by the elastic ring plate can squeeze the sealing ring, so that the worn part of the sealing ring can be put into contact with the inner wall of the outer ring of the bearing body again, thereby improving the sealing effect of the sealing ring on the bearing body.

[0021] In this embodiment, by setting the bearing body 1, after the operator fixes the sealing ring 4 inside the placement groove 3, the positioning component is used to position the elastic ring 6, so that the elastic ring 6 can be fixed inside the adjustment groove 5. At this time, the elastic force released by the elastic ring 6 can squeeze the sealing ring 4, so that the sealing ring 4 can tightly seal the spacer ring 2 and the outer ring of the bearing body 1, thereby preventing the lubricating oil inside the bearing body 1 from flowing out or being contaminated by the outside. At the same time, when the sealing ring 4 wears after long-term use, the elastic force continuously released by the elastic ring 6 can squeeze the sealing ring 4, so that the worn part of the sealing ring 4 can be put into contact with the inner wall of the outer ring of the bearing body 1 again, thereby improving the sealing effect of the sealing ring 4 on the bearing body 1.

[0022] Specifically, the positioning component includes a connecting ring 7, which is fixedly connected inside the adjusting groove 5. The connecting ring 7 is made of elastic material, and a connecting groove 8 is provided at one end of the connecting ring 7. The elastic ring 6 is movably fitted together with the connecting groove 8. In this embodiment, by setting a connecting ring 7, the elastic ring 6 and the connecting groove 8 are movably fitted together. At this time, the compressive force released by the elastic ring 6 can be evenly transmitted to the sealing ring 4 through the connecting ring 7, so that the sealing ring 4 can deform. Specifically, one end of the elastic ring 6 is fixedly connected to a fixing ring 9, and the fixing ring 9 is movably installed together with the adjusting groove 5; In this embodiment, by setting a fixing ring 9, the fixing ring 9 is movably installed inside the adjusting groove 5, and then the sealing ring 4 is placed inside the placement groove 3, so that the elastic ring 6 can be fixed inside the adjusting groove 5. Specifically, a retaining ring 10 is provided inside the bearing body 1, and a first sealing ring 11 is fixedly connected to the outer wall surface of the retaining ring 10; In this embodiment, by setting a blocking ring 10, since the outer wall surface of the blocking ring 10 is fixedly connected with a first sealing ring 11, the first sealing ring 11 can seal the space between the blocking ring 10 and the outer ring of the bearing body 1.

[0023] Specifically, a second sealing ring 12 is fixedly connected to the inner wall surface of the blocking ring 10, and a number of anti-slip grooves 13 are provided at one end of the blocking ring 10. In this embodiment, by setting a blocking ring 10, since the outer wall surface of the blocking ring 10 is fixedly connected with a second sealing ring 12, the second sealing ring 12 can seal the space between the blocking ring 10 and the inner ring of the bearing body 1.

[0024] Specifically, a mounting groove 14 is provided on one side of the partition ring 2, and a mounting ring 15 is fixedly connected to one end of the blocking ring 10. The mounting ring 15 is threadedly connected to the mounting groove 14. In this embodiment, by setting an installation ring 15 and threading the installation ring 15 to the installation groove 14, it is convenient to install and remove the blocking ring 10 later.

[0025] Working steps: 1. By setting the bearing body 1, after the operator fixes the sealing ring 4 inside the placement groove 3, the positioning component is used to position the elastic ring 6, so that the elastic ring 6 can be fixed inside the adjustment groove 5. At this time, the elastic force released by the elastic ring 6 can squeeze the sealing ring 4, so that the sealing ring 4 can tightly seal the spacer ring 2 and the outer ring of the bearing body 1, thereby preventing the lubricating oil inside the bearing body 1 from flowing out or being contaminated by the outside. At the same time, when the sealing ring 4 wears after long-term use, the elastic force continuously released by the elastic ring 6 can squeeze the sealing ring 4, so that the worn part of the sealing ring 4 can be put into contact with the inner wall of the outer ring of the bearing body 1 again, thereby improving the sealing effect of the sealing ring 4 on the bearing body 1. Second, by setting the connecting ring 7, the elastic ring 6 is movably fitted together with the connecting groove 8. At this time, the extrusion force released by the elastic ring 6 can be evenly transmitted to the sealing ring 4 through the connecting ring 7, so that the sealing ring 4 can deform. By setting the fixing ring 9, the fixing ring 9 is movably installed inside the adjusting groove 5. After the sealing ring 4 is placed inside the placement groove 3, the elastic ring 6 can be fixed inside the adjusting groove 5. By setting the mounting ring 15, the mounting ring 15 is threadedly connected to the mounting groove 14, which facilitates the later installation and removal of the blocking ring 10.
