Abstract
The utility model relates to an end face seal ring, which comprises a seal ring body (1). The cross section of the seal ring body (1) is V-shaped. The end face seal ring is characterized in that backward prick-shaped protrusions towards the center direction are arranged one outside lateral face of the seal ring body (1). A plurality of backward prick-shaped protrusions are contacted with surface of a sleeve ring or a gasket to form a plurality of stopping dams. The end face seal ring effectively stops oil or oil liquid from leaking outwards, and then improves sealing property.
Description
Technical field
The utility model relates to a kind of end-face seal ring.
Background technique
Seal ring is fixed on lasso or the packing ring of bearing and with another lasso or packing ring and contacts or form narrow labyrinth clearance, can prevent internal grease or fluid to external leakage, also can prevent extraneous dabbling or the intrusion of dust.Seal ring of a great variety pacified its sectional shape and can be divided into O RunddichtringO and V-shaped seal ring etc.Conventional V-shaped seal ring, its sectional shape is " V " font, and its main oil sealing district is smooth plane; Small gap can be left with the surface of lasso or packing ring in the assembling back; During work, grease or fluid easily along this gap to external leakage, thereby influence sealing effect.
Summary of the invention
The utility model is to overcome above-mentioned deficiency, and a kind of good airproof performance, antileakaging end-face seal ring are provided.
The purpose of the utility model is achieved in that a kind of end-face seal ring, and it comprises the seal ring body, and said this body section of seal ring is in the shape of the letter V, and an outer side surface of said seal ring body is provided with to the reversed acanthoid of central direction protruding.
Said reversed acanthoid is raised with multiple tracks.Be preferably the 3-5 road.
Compared with prior art, the beneficial effect of the utility model end-face seal ring is:
The utility model end-face seal ring, the multiple tracks reversed acanthoid is protruding to be contacted with the surface of lasso or packing ring, forms multiple tracks interception dam, effectively stops grease or fluid to external leakage, thereby improves sealability.
Description of drawings
Fig. 1 is the utility model end-face seal ring structural representation.
Fig. 2 is the A portion enlarged view of Fig. 1.
Among the figure:
Seal ring body 1;
Protruding 2.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model end-face seal ring, it comprises seal ring body 1, and said seal ring body 1 cross section is in the shape of the letter V, and an outer side surface of said seal ring body 1 is provided with the reversed acanthoid protruding 2 to central direction.
Said reversed acanthoid protruding 2 has multiple tracks, is preferably the 3-5 road.
During use, multiple tracks reversed acanthoid protruding 2 contact with the surface of lasso or packing ring, forms multiple tracks and tackles the dam, effectively stops grease or fluid to external leakage, thus the raising sealability.
