Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, and specifically to a novel sealing ring. Background Technology

[0002] A sealing ring is a device used to prevent the leakage of liquids or gases. It is typically made of elastic materials and serves a sealing function. The choice of material is crucial to its sealing performance and service life; the material's properties directly affect the sealing ring's performance. It is used as a pressureless seal for rotating shafts. The sealing lip has good mobility and adaptability, compensating for large tolerances and angular deviations. It prevents internal grease or oil from leaking out and also prevents external splashes of water or dust from entering.

[0003] Precautions for installing and using sealing rings:

[0004] (1) Do not install it in the wrong direction or damage the lip edge. If there are scratches larger than 50μm on the lip edge, it may cause obvious oil leakage.

[0005] (2) Prevent forced installation. Do not hammer it in. Instead, use a special tool to press the sealing ring into the seat hole first, and then use a simple cylinder to protect the lip as it passes through the spline section. Before installation, apply some lubricant to the lip to facilitate installation and prevent burns during initial operation. Keep it clean.

[0006] (3) Prevent exceeding the service life. The service life of the rubber seals of dynamic seals is generally 3000 to 5000 hours, and new seals should be replaced in time.

[0007] (4) The size of the sealing rings must be consistent when replacing them. The sealing rings of the same size must be selected strictly according to the instructions. Otherwise, the required tightness and other requirements cannot be guaranteed.

[0008] (5) Avoid using old sealing rings. When using new sealing rings, carefully check their surface quality to ensure that there are no defects such as pinholes, protrusions, cracks and grooves and that they have sufficient elasticity before use.

[0009] (6) During installation, all parts of the opened hydraulic system should be thoroughly cleaned first. It is best to use special tools to prevent sharp metal edges from cutting your fingers.

[0010] (7) When replacing the sealing ring, the sealing ring groove must be strictly inspected, dirt must be removed, and the bottom of the groove must be polished.

[0011] (8) To prevent damage and oil leakage, the operation must be carried out in accordance with the procedures. At the same time, the machine should not be overloaded for a long time or placed in a harsh environment.

[0012] Existing sealing rings generally meet the requirements, but they still have the following shortcomings:

[0013] 1. Since existing sealing rings are basically made of rubber, they need to be squeezed to reach the intended position when installed in the position that needs to be sealed. Excessive squeezing will exceed the pressure resistance limit of the sealing ring and shorten its service life.

[0014] 2. When installing the sealing ring, it needs to be tightened with a nut. The torque of the nut during tightening causes the surface of the sealing ring to twist, which greatly reduces the sealing effect of the sealing ring. Utility Model Content

[0015] Therefore, this utility model provides a novel sealing ring to solve the above-mentioned problems in the prior art.

[0016] To achieve the above objectives, this utility model provides the following technical solution:

[0017] According to a first aspect of the present invention, a novel sealing ring includes a sealing ring body, wherein a circular hole is provided inside the sealing ring body, the circular hole being arranged in a ring shape inside the sealing ring body, a ball being rolledly connected inside the circular hole, an annular pad being provided at the top and bottom of the sealing ring body, an annular ring being fixedly connected to the inner and outer side walls of the annular pad, and an arc-shaped plate being fixedly connected to the end of the annular ring away from the annular pad, the side of the arc-shaped plate away from the annular ring contacting the ball.

[0018] Furthermore, two-thirds of the ball is located inside the circular hole.

[0019] Furthermore, an arc-shaped groove is provided inside the sealing ring body and on one side of the ball, and the arc-shaped plate is located inside the arc-shaped groove.

[0020] Furthermore, a vertical groove is provided on the side of the arc-shaped groove away from the ball, and the vertical groove is connected to the arc-shaped groove.

[0021] Furthermore, the vertical groove extends to the outside of the sealing ring body, and the annular ring is located inside the vertical groove.

[0022] Furthermore, both the annular ring and the annular pad are made of aluminum alloy.

[0023] Furthermore, the main body of the sealing ring is made of fluororubber.

[0024] The present invention has the following advantages: by setting the annular gasket and annular ring, the pressure resistance of the sealing ring is increased and the service life of the sealing ring is extended. By cooperating with the arc plate and the ball, the torque of the nut can be used to prevent the surface of the sealing ring from twisting when the nut is tightened, thereby improving the sealing effect of the sealing ring.

[0032] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1 to 6 As shown, a novel sealing ring according to the first aspect of this utility model includes a sealing ring body 1, with a circular hole 2 inside the sealing ring body 1 arranged in a ring shape inside the sealing ring body 1. A ball bearing 3 is rolled inside the circular hole 2. An annular pad 4 is provided at the top and bottom of the sealing ring body 1. An annular ring 5 is fixedly connected to the inner and outer side walls of the annular pad 4. An arc-shaped plate 6 is fixedly connected to the end of the annular ring 5 away from the annular pad 4. The side of the arc-shaped plate 6 away from the annular ring 5 is in contact with the ball bearing 3.

[0035] In the above embodiments, it should be noted that there is a very small gap between the annular gasket 4 and the sealing ring body 1. When the new sealing ring is in use, firstly, as the nut is turned, the nut drives the annular gasket 4, the annular ring 5 and the arc plate 6 to rotate on the surface of the ball 3. As the nut is turned tighter and tighter, it presses down on the annular gasket, causing the two arc plates 6 to move toward the center of the sealing ring body 1 and make close contact with the ball 3.

[0036] The technical effects achieved by the above embodiments are as follows: by setting the annular gasket 4 and the annular ring 5, the pressure resistance of the sealing ring is increased and the service life of the sealing ring is extended. By cooperating with the arc plate 6 and the ball 3, when the nut is tightened, the torque of the nut can be used to prevent the surface of the sealing ring from twisting, thereby improving the sealing effect of the sealing ring.

[0041] like Figures 1 to 4 As shown, a novel sealing ring includes all the contents of Embodiment 1. In addition, an arc-shaped groove 7 is provided inside the sealing ring body 1 and on one side of the ball 3, and the arc-shaped plate 6 is located inside the arc-shaped groove 7.

[0042] In the above embodiments, it should be noted that the arc plate 6 can slide inside the arc groove 7, realizing relative positional displacement between the arc plate 6 and the ball 3, and further enabling the annular pad 4 to move on the top of the sealing ring body 1.

[0043] Example 4

[0044] like Figures 1 to 4 As shown, a novel sealing ring includes all the contents of Embodiment 3. In addition, a vertical groove 8 is provided on the side of the arc groove 7 away from the ball 3, and the vertical groove 8 is connected to the arc groove 7.

[0045] In the above embodiments, it should be noted that when the arc plate 6 can slide inside the arc groove 7, it can drive the annular ring 5 to slide inside the vertical groove 8 via the arc plate 6.

[0046] Example 5

[0047] like Figures 1 to 4 As shown, a novel sealing ring includes all the contents of Embodiment 4. In addition, the vertical groove 8 extends to the outside of the sealing ring body 1, and the annular ring 5 is located inside the vertical groove 8.

[0048] In the above embodiments, it should be noted that by extending the vertical groove 8 to the outside of the sealing ring body 1, the annular ring 5 inside the vertical groove 8 is connected to the annular pad 4. This enables the annular ring 5 to move in the vertical groove 8 by moving the arc plate 6 on the ball 3, and further enables the annular pad 4 to move at the top of the sealing ring body 1.

[0049] Example 6

[0050] like Figures 1 to 4 As shown, a novel sealing ring includes all the contents of Example 4. In addition, both the annular ring 5 and the annular gasket 4 are made of aluminum alloy.

[0051] In the above embodiments, it should be noted that the use of aluminum alloy material has the advantages of strong filling capacity, low shrinkage rate, less susceptibility to cracking, good corrosion resistance, light weight, good mechanical properties, high compressive strength, and durability.

[0052] Example 7

[0053] like Figures 1 to 4 As shown, a novel sealing ring is provided, which includes all the contents of Example 4. In addition, the sealing ring body 1 is made of fluororubber.

[0054] In the above embodiments, it should be noted that it has excellent high temperature resistance, oil resistance, and chemical corrosion resistance, and is especially suitable for applications that require compatibility with various hydraulic oils, fuels, and many chemical substances.

[0055] Working principle: When this new type of sealing ring is in use, as the nut is turned, the nut drives the annular washer 4, the annular ring 5 and the arc plate 6 to rotate on the surface of the ball 3. As the nut is turned tighter and tighter, it presses down on the annular washer, causing the two arc plates 6 to move toward the center of the sealing ring body 1 and make close contact with the ball 3.
