Description

Technical Field

[0001] The utility model belongs to the technical field of sealing, and in particular relates to a novel sealing ring. Background Art

[0002] Conventionally, seal rings are used in various fields of automobiles and industrial equipment to seal liquids such as oil and water, and gases such as air and gas inside the device. The seal ring is formed of an annular member formed of an elastomer, and seals between the end faces of two members by using the rebound force generated by radial elastic deformation when installed between the end faces of the two members, thereby preventing leakage of various fluids.

[0003] The existing sealing ring structure has a single shape, the thickness of each part is consistent, and the deformation amount is basically the same. For products with a relatively complex shaft sleeve gap structure, the sealing effect is not good and the installation reliability is low. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the utility model provides a new type of sealing ring which has better oil locking effect, long service life and easy positioning.

[0005] The technical solution adopted by the utility model is:

[0006] A new type of sealing ring includes an X-shaped body, wherein the X-shaped body includes an inner ring and an outer ring, wherein the upper and lower convex parts of the inner ring are both arc-shaped structures, wherein the convex parts of the inner ring are arranged higher or lower than the convex parts of the corresponding sides of the outer ring, and oil storage grooves are arranged between adjacent convex parts. The utility model is provided with oil storage grooves on each surface, which can store more grease, so that the contact friction between the sealing ring and the chain plate during the transmission process is more lubricated, and the seal is less prone to aging. During the installation process, the inner ring is sleeved on the inner single section to hold the inner single section tightly, so that the sealing ring is easier to position during the assembly process, and the sealing ring failure caused by the sealing ring being cut off due to inaccurate positioning of the sealing ring is reduced.

[0007] Furthermore, the diameter of the lower arc-shaped structure is greater than the diameter of the upper arc-shaped structure.

[0008] Furthermore, the inner side of the lower arc-shaped structure is arranged to protrude from the inner side of the upper arc-shaped structure.

[0009] Furthermore, a lower convex portion of the lower arc-shaped structure is arranged higher than the outer ring.

[0010] Furthermore, an upper convex portion of the upper arc-shaped structure is provided which is lower than the outer ring.

[0011] Furthermore, a middle convex portion is provided in the middle of the concave surface between the upper and lower convex portions of the outer ring.

[0012] Furthermore, the lateral widths of the upper and lower protrusions of the outer ring are consistent.

[0013] Furthermore, the lateral width of the middle convex portion is smaller than the lateral width of the convex portion of the outer ring.

[0014] Furthermore, the maximum angle between adjacent protrusions is 45°.

[0015] Furthermore, the material of the X-shaped body is imported nitrile rubber numbered XNBR, and its Brinell hardness is 85 degrees.

[0016] Beneficial effects of the utility model:

[0017] 1. Each surface is provided with oil storage grooves, which can store more grease. The contact friction between the sealing ring and the chain plate during the transmission process is more lubricated, and the seal is less likely to age.

[0018] 2. During the installation process, the inner ring is put on the inner single section to hold the inner single section tightly, which makes it easier to position the sealing ring during the assembly process and reduces the failure of the sealing ring caused by the sealing ring being cut off due to inaccurate positioning of the sealing ring.

[0019] 3. Each side of the sealing ring is designed with two layers to better lock the oil. BRIEF DESCRIPTION OF THE DRAWINGS
