Example 1:
in order to omit the step of additionally arranging a notch for storing lubricating oil between a transmission shaft and a pipe fitting to ensure normal transmission and ensure a space for storing the lubricating oil, the double-ring sealing ring provided by embodiment 1 of the utility model, as shown in fig. 1-2, comprises a sealing ring body 1, wherein the sealing ring body 1 is a circular cylinder, and the sealing ring body 1 comprises an upper surface 11, a lower surface 12, an outer side surface 13 and an inner side surface 14; both the upper surface 11 and the lower surface 12 are planar; two annular protrusions 2 are arranged on the outer side surface 13; the protrusion 2 is a circular cylinder and comprises a first bottom surface 21 and a second bottom surface 22; the first bottom surface 21 of one of the protrusions 2 is coplanar with the upper surface 11; the first bottom surface 21 of the other projection 2 is coplanar with the lower surface 12; the inner sides of the circular rings of all the bulges 2 are completely attached to the outer side surface 13 and fixedly arranged on the sealing ring body 1; the protrusion 2 and the sealing ring body 1 are integrally formed; a first gap space 23 is left between the two protrusions 2; the inner side surface 14 is provided with two annular leakage-proof sealing rings 3 which protrude from the inner side surface 14 to the interior of the sealing ring body 1; a second gap space 31 is reserved between the two leakproof seal rings 3; the leakproof seal ring 3 and the seal ring body 1 are integrally formed.
When the double-ring sealing ring capable of hiding grease provided by the embodiment 1 of the utility model works, the sealing ring body is sleeved on the transmission shaft, and the leakage-proof sealing ring 3 is fully contacted with the transmission shaft; the protrusion 2 is annular, the outermost ring of the protrusion 2 is in contact with an external pipe fitting part, and the outermost ring of the protrusion 2 is in a concentric circle shape when viewed from the cross section and is respectively provided with a transmission shaft, a sealing ring and a pipe fitting from inside to outside, wherein the protrusion 2 integrally formed with the sealing ring body 1 can be attached to the pipe fitting, and a hollow closed space first gap space 23 is formed between the inner wall of the pipe fitting, the two protrusions 2 and the outer side surface 13; a closed space second gap space 31 is formed between the two leakproof seal rings 3 and the inner side surfaces 14 of the transmission shaft and the seal ring body; when the transmission shaft moves relative to the pipe fitting, the leakproof seal ring 3 can enable the transmission shaft and the pipe fitting to be divided into an upper space and a lower space by taking the seal ring as the center, and the two spaces do not influence each other, so that the sealing effect is achieved; at the first interstitial space 23, the motion between the transmission shaft and the pipe can be assisted by filling with lubricating oil; the second gap space 31 can ensure that a certain space is left to relieve the problem of failure of a transmission structure caused by expansion when the transmission shaft or a sealing ring or lubricating oil expands due to heat generated by heat expansion and cold contraction transmission; in addition, lubricating oil may be added to the inside of the second gap space 31 as needed to enhance the lubricating effect. The utility model discloses need not additionally set up the notch that is used for holding lubricating oil on can making transmission shaft or pipe fitting in order to guarantee the transmission, just can store lubricating oil in that the sealing washer is inside, reduce the process steps of transmission shaft and pipe fitting processing.
In order to make the second clearance space 31 between the protrusions 2 more easily contract when the internal components or the lubricating oil expand after the transmission shaft generates heat, in this embodiment, an arc-shaped surface 221 is formed between the second bottom surface 22 and the outer ring cylindrical surface of the protrusions 2. At this time, if the inner portion is expanded, the projection 2 is expanded outwardly with the arc-shaped surface 221, so that the distance between the outer side surface 13 of the seal ring and the inner wall of the pipe becomes smaller.
Because the sealing ring and the transmission shaft are usually in interference fit, in the embodiment, the cross section of the leakage-proof sealing ring 3 is semicircular, the semicircular straight edges of the leakage-proof sealing ring 3 are arranged on the inner side surface 14 of the sealing ring body 1, and the semicircular arc edges of the two leakage-proof sealing rings 3 are respectively tangent to the upper surface 11 and the lower surface 12 of the sealing ring body 1. The leak-proof sealing ring 3 with the semicircular section can fix the sealing ring on the transmission shaft more easily.
In order to better fit the sealing ring and to make the second clearance space 31 more easily open when deformed due to thermal expansion and contraction, in this embodiment, flexible materials are used for the protrusions 2 and the leak-proof sealing ring 3. The protrusions 2 are made of flexible materials, so that the two protrusions 2 are easy to deform when the interior of the pipe fitting expands, and the protrusions are far away from each other, so that the gap between the sealing ring and the pipe fitting is reduced, and the transmission component can normally transmit; the leakproof seal ring 3 is made of flexible materials, so that the seal ring can be mounted to the transmission shaft in an interference fit mode more easily.
To sum up, the utility model discloses a double-ring sealing ring capable of hiding grease, relating to the technical field of sealing rings and comprising a sealing ring body, wherein the sealing ring body is a circular cylinder and comprises an upper surface, a lower surface, an outer side surface and an inner side surface; the upper surface and the lower surface are both planar; two annular bulges are arranged on the outer side surface; the protrusion is a circular cylinder and comprises a first bottom surface and a second bottom surface; wherein the first bottom surface of one of the protrusions is coplanar with the upper surface; said first bottom surface of another of said protrusions being coplanar with said lower surface; the inner sides of all the raised circular rings are completely attached to the outer side surface and are fixedly arranged on the sealing ring body; the protrusion and the sealing ring body are integrally formed; a first gap space is reserved between the two bulges; the inner side surface is provided with two annular leakage-proof sealing rings protruding from the inner side surface to the inside of the sealing ring body; a second gap space is reserved between the two leakproof sealing rings; the leakage-proof sealing ring and the sealing ring body are integrally formed.
