Description

Oil seal anti-cracking sealing ring

Technical Field

The utility model relates to a sealing ring especially relates to an oil blanket crack control sealing ring.

Background

The sealing ring is an annular sealing element with a notch, the sealing ring is placed in an annular groove of a sleeve, the sleeve and a shaft rotate together, the sealing ring is tightly pressed on the inner hole wall of a static element by the elasticity of the pressed notch, and the sealing ring can play a role of sealing.

Because the service environment of oil blanket sealing ring is very abominable, the oil blanket sealing ring is the both sides of lug connection at the wheel generally, so the oil blanket sealing ring is in the in-service use in-process, the breach appears in the surface very easily, the staff uses naked eye to be difficult to discover, if the breach then can lead to the inside liquid leakage of oil blanket seriously, and because present sealing ring is dustproof relatively poor in the effect, tiny dust still can get into in the oil blanket, along with the accumulation dust of time can be more and more, then the dust enters into on the seal lip, and then cause the transitional wear of sealing ring, inefficacy and oil leak, finally lead to the life of sealing ring to shorten.

Therefore, it is highly desirable to design an anti-cracking sealing ring for oil seal, which not only has a long service life, but also can prevent cracks and fractures during use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome among the above-mentioned prior art oil blanket seal ring breach appears easily in the use, and then leads to the liquid leakage in the oil blanket, and the dustproof effect of sealing ring is relatively poor, and the shortcoming of sealing ring transition wearing and tearing can be leaded to for a long time, technical problem: the oil seal anti-cracking sealing ring has long service life and can prevent cracking and fracture in the using process.

The technical scheme is as follows: an oil seal anti-cracking sealing ring comprises a shell, a static ring, an anti-cracking ring and a dynamic ring, wherein the static ring is connected in the shell, the anti-cracking ring is connected in the static ring, and the dynamic ring is connected in the anti-cracking ring.

Optionally, the anti-cracking device further comprises a heat insulation ring and a rubber sleeve, the heat insulation ring is connected in the anti-cracking ring, the rubber sleeve is connected in the heat insulation ring, and the movable ring is sleeved on the inner side of the rubber sleeve.

Optionally, the housing is peripherally perforated with a plurality of air inlet holes.

Optionally, the housing is peripherally grooved with a plurality of anti-slip grooves.

Optionally, the rubber sleeve is made of nitrile rubber with high sealing performance and good oil resistance.

Optionally, the housing is made of alloy material.

Optionally, the lower part of the housing is provided with a slope.

It is right to have adopted the utility model discloses the description of structure can know, the utility model discloses a design departure point, theory and advantage are: 1. the utility model discloses under the effect of crack control ring, and then can prevent this sealing ring fracture from appearing in the use to the life of this sealing ring has been increased.

2. Under the effect of antiskid groove, and then the staff of being convenient for dismantles the sealing ring.

Detailed Description

The invention will be further described with reference to specific examples, wherein the terms, unless otherwise expressly specified or limited, are as follows: the arrangement, mounting, connection should be understood broadly, for example, they may be fixed connections, detachable connections, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1

An oil seal anti-cracking sealing ring is shown in figures 1-3 and comprises a shell 1, a static ring 2, an anti-cracking ring 3 and a movable ring 6, wherein the static ring 2 is connected in the shell 1, the lower portion of the shell 1 is arranged on an inclined plane, the anti-cracking ring 3 is connected in the static ring 2, the anti-cracking ring 3 is used for placing the sealing ring to crack, the movable ring 6 is connected in the anti-cracking ring 3, a plurality of air inlet holes 7 are formed in the shell 1 along the periphery, eight air inlet holes 7 are formed in the shell 1, a plurality of anti-skidding grooves 8 are formed in the shell 1 along the periphery, and eight anti-skidding grooves 8 are formed in the anti-skidding grooves 8.

When the staff need install this sealing ring, the staff cup joints quiet ring 2 in 1 inboard of shell at first, shell 1 sets up to harder alloy material, the staff cup joints anti-crack ring 3 in quiet ring 2 inboard afterwards, anti-crack ring 3 can play the effect of connecting each part of this sealing ring, because anti-crack ring 3 itself is stand wear and tear, and then can prevent this sealing ring fracture in the use, the life of this sealing ring has been increased, anti-crack ring 3 inboard reconnection rotating ring 6 afterwards, because shell 1 lower part is the inclined plane setting, in the use, can prevent that the dust from getting into in the oil blanket, the leakproofness of this sealing ring has been strengthened, and then can prevent this sealing ring wearing and tearing excessively to lead to phenomenons such as oil leak, finally, this sealing ring of use for more convenient, the staff is convenient for dismantling this sealing ring through eight anti-skid grooves 8, the hand takes off when preventing to dismantle the sealing ring, under the effect of eight inlet ports 7, and then can be convenient for carry out the thermal treatment to the oil blanket.

Example 2

On the basis of embodiment 1, as shown in fig. 1 and fig. 4, the heat insulation device further comprises a heat insulation ring 4 and a rubber sleeve 5, the heat insulation ring 4 is connected in the anti-cracking ring 3, the heat insulation ring 4 is used for insulating heat, the rubber sleeve 5 is connected in the heat insulation ring 4, the rubber sleeve 5 is made of nitrile rubber with high sealing performance and good oil resistance, and the movable ring 6 is sleeved on the inner side of the rubber sleeve 5.

Finally, in order to strengthen the heat-proof performance of this sealing ring, the staff cup joints heat insulating ring 4 at the crack prevention ring 3 inboardly, and heat insulating ring 4 high temperature resistance is better, can prevent that the inside high temperature of oil blanket from influencing this sealing ring, and the staff cup joints rubber sleeve 5 in heat insulating ring 4 inboards afterwards, because 5 tensile properties of rubber sleeve are better, can increase the tensile strength of this sealing ring.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
