Technical Field
[0001] The utility model belongs to the technical field of sealed bearings, in particular to a sealed bearing. Background Art
[0002] Bearings are a crucial component in modern machinery. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. To ensure bearing life and mechanical performance, and to reduce internal friction, bearings are typically filled with lubricating oil.
[0003] Currently, some existing sealed bearings use sealing rings to seal the bearings, thereby preventing or reducing the leakage of lubricating oil from the inside of the bearings. However, this sealing treatment also makes it relatively difficult to add lubricating oil to the sealed bearings when necessary, and is relatively inconvenient to maintain. Therefore, we propose a sealed bearing to solve or improve the above problems. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a sealed bearing, which can effectively solve the problems of the prior art.
[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0006] The utility model is a sealed bearing, comprising a bearing body, a rotating ring slidably mounted on the surface of the bearing body, a storage groove opened inside the bearing body, an oil injection channel opened inside the storage groove, a push block fixed on the surface of the rotating ring, an oil injection port opened on the surface of the bearing body, and a pressure relief port opened on the surface of the bearing body.
[0007] Furthermore, a fixing frame is fixed to the inner surface of the pressure relief port, and a limiting rod is inserted into the interior of the fixing frame.
[0008] Furthermore, a sealing gasket is fixed to the top end of the limiting rod, and the top end of the sealing gasket contacts the inner surface of the pressure relief port.
[0009] Furthermore, a spring is sleeved on the surface of the limiting rod, one end of the spring contacts the surface of the sealing gasket, and the other end contacts the surface of the fixing frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: by arranging the oil filling port, the storage tank, the oil filling channel and the push block, the lubricating oil can be injected into the storage tank through the oil filling port when it is necessary to add lubricating oil to the inside of the bearing main body for maintenance. At this time, the rotating ring can be rotated to drive the push block to move, so that the push block pushes the lubricating oil inside the storage tank to one side of the oil filling channel and squeezes out from the inside of the oil filling channel, so that the lubricating oil enters the inside of the bearing main body through the oil filling channel, completing the maintenance of the bearing main body. Adding lubricating oil to the inside of the bearing main body is relatively simple, and maintenance and maintenance are relatively convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0022] See also Figure 1-6As shown, the utility model is a sealed bearing, comprising a bearing body 1, a rotating ring 2 slidably mounted on the surface of the bearing body 1, and an anti-skid pattern on the surface of the rotating ring 2. The anti-skid pattern can increase the friction between the surface of the rotating ring 2 and the fingers, thereby facilitating the rotation of the rotating ring 2 and reducing the phenomenon of slipping between the fingers and the surface of the rotating ring 2 when the personnel rotate the rotating ring 2. A limiting ring is fixed on the surface of the rotating ring 2. The limiting ring is located inside the bearing body 1 and is slidably connected to the bearing body 1. Two groups of limiting rings are symmetrically fixed on the surface of the rotating ring 2. The limiting rings can limit the position of the rotating ring 2 to avoid The rotating ring 2 is detached from the surface of the bearing body 1, and the storage groove 7 is opened inside the bearing body 1. The storage groove 7 is arranged in a plurality of groups on the inner circumference of the bearing body 1. The oil injection channel 6 is opened inside the storage groove 7. The oil injection channel 6 is opened in a plurality of groups at equal intervals inside a group of storage grooves 7. One end of the oil injection channel 6 is connected to the interior of the storage groove 7, and the other end is connected to the interior of the bearing body 1. The push block 10 is fixed to the surface of the rotating ring 2. The push block 10 is located inside the storage groove 7 and is slidably connected to the storage groove 7. When the rotating ring 2 rotates, it drives the fixed push block 10 to rotate, so that the push block 10 moves along the inside of the storage groove 7. When lubricating oil is provided inside the storage tank 7, the push block 10 moves inside the storage tank 7 to push the lubricating oil provided inside the storage tank 7 to move, so that the lubricating oil moves to the side close to the oil filling channel 6 and flows into the interior of the bearing body 1 through the oil filling channel 6, thereby reducing or avoiding the lubricating oil remaining inside the storage tank 7 and reducing the waste of lubricating oil. The oil filling port 3 is opened on the surface of the bearing body 1, and the internal space of the oil filling port 3 is connected with the internal space of the storage tank 7. The number of the oil filling ports 3 is the same as the number of the storage tanks 7. A top screw 4 is provided on one side of the oil filling port 3, and the top screw 4 can be threadedly installed inside the oil filling port 3 When the top screw 4 is threadedly installed in the oil filling port 3, the top screw 4 can seal the oil filling port 3, thereby preventing the lubricating oil from flowing out of the storage tank 7 through the oil filling port 3, reducing the waste of lubricating oil. At the same time, when the top screw 4 is threadedly installed in the oil filling port 3, it also prevents dust and debris from entering the storage tank 7 through the oil filling port 3, thereby preventing dust and debris from entering the storage tank 7 through the oil filling port 3 and causing pollution to the interior of the storage tank 7. The pressure relief port 5 is opened on the surface of the bearing body 1, and the internal space of the pressure relief port 5 is connected to the internal space of the storage tank 7. The number of the pressure relief ports 5 is the same as the number of the storage tanks 7.
[0023] The inner surface of the pressure relief port 5 is fixed with a fixing frame 12, and the number of fixing frames 12 is the same as the number of pressure relief ports 5. A limiting rod 11 is inserted into the interior of the fixing frame 12, and the number of limiting rods 11 is the same as the number of fixing frames 12. A sealing gasket 8 is fixed to the top of the limiting rod 11. When the sealing gasket 8 moves, it drives the fixed limiting rod 11 to move. The limiting rod 11 can limit the position of the sealing gasket 8 to prevent the sealing gasket 8 from tilting when it moves, thereby improving the stability of the sealing gasket 8 when it moves. The number of sealing gaskets 8 is the same as the number of limiting rods 11. The top of the sealing gasket 8 contacts the inner surface of the pressure relief port 5, and the surface of the limiting rod 11 is sleeved with a spring 9. One end of the spring 9 contacts the surface of the sealing gasket 8, and the other end contacts the surface of the fixing frame 12. When the sealing gasket 8 moves, it squeezes the spring 9 to cause the spring 9 to deform. When there is no external force interference, the spring 9 will push the sealing gasket 8 to move. At the same time, the spring 9 can apply a certain thrust to the surface of the sealing gasket 8, so that the sealing gasket 8 When the push block 10 moves to one side of the oil filling channel 6 and squeezes the lubricating oil in the storage tank 7 into the interior of the bearing body 1 through the oil filling channel 6, the air outside the bearing body 1 can squeeze the sealing gasket 8 through the atmospheric pressure to move the sealing gasket 8, so that the top of the sealing gasket 8 no longer closely adheres to the inner surface of the pressure relief port 5 to seal the pressure relief port 5, thereby allowing external air to enter the interior of the storage tank 7 through the pressure relief port 5 and balance the air pressure inside the storage tank 7, thereby preventing the lubricating oil injected into the bearing body 1 from being re-sucked into the interior of the storage tank 7 through the oil filling channel 6 due to the reduction of the air pressure inside the storage tank 7 when the push block 10 moves in the reverse direction, thereby improving the lubrication effect.
[0024] Working principle: When it is necessary to add lubricating oil to the bearing body 1 for maintenance, the lubricating oil can be injected into the storage tank 7 through the oil filling port 3. After the lubricating oil is injected into the storage tank 7, the rotating ring 2 can be rotated to make the rotating ring 2 drive the push block 10 to move. When the push block 10 moves, the surface of the push block 10 will move to the side of the oil filling port 3, thereby blocking the oil filling port 3, preventing the lubricating oil inside the storage tank 7 from being squeezed out from the inside of the storage tank 7 through the oil filling port 3 when the push block 10 moves, reducing the waste of lubricating oil. At the same time, when the push block 10 moves, it will push the lubricating oil inside the storage tank 7 to move to one side of the oil filling channel 6, so that the lubricating oil moves to The lubricating oil is squeezed out from one side of the dry group oil filling channel 6 and from the inside of several groups of oil filling channels 6, so that the lubricating oil can enter the interior of the bearing main body 1 through the oil filling channel 6, completing the maintenance of the bearing main body 1. It is relatively simple to add lubricating oil to the inside of the bearing main body 1, and the maintenance and maintenance are relatively convenient. At the same time, the above method can facilitate personnel to add lubricating oil or grease of different viscosities to the inside of the storage tank 7 according to use needs and squeeze it into the interior of the bearing main body 1 through the push block 10 and the oil filling channel 6, avoiding the problem that the lubricating oil or grease cannot be added to the inside of the bearing main body 1 due to its high viscosity and poor fluidity, thereby improving the adaptability of the bearing to lubricating oil or grease of different viscosities.
[0025] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
