Abstract
The utility model relates to a sealing ring with an oil impurity blocking structure. The sealing ring comprises a support framework and a sealing body, wherein the support framework is wrapped by the sealing body; the support framework takes the L shape; a groove is arranged inside the extending part of the sealing body used for wrapping the support framework; a spring ring is sheathed in the groove; and a dustproof lip, a main sealing lip and an oil impurity blocking lip are arranged outside the extending part from bottom to top. In the utility model, with the improvement of the structure of the oil impurity blocking lip, according with the present service conditions, the resisting capacity for the oil impurity can be improved, and the service life of the sealing ring can be prolonged.
Description
Technical field
The utility model relates to a kind of seal ring, especially relates to a kind of seal ring that has impurity barrier structure in the oil.
Background technique
At present, for the parts of needs sealing, the requirement of turbidity test is arranged all generally.But because aspect more such as technology, conditions of manufacture often is difficult to reach desired turbidity test; At this moment, remain in the various impurity in the parts cavity: sand that iron filings, greasy dirt or the casting that forms such as machining adheres to or the like impurity, all can be after assembling is finished sneak into oil along with the injection of oils.In the working procedure, these impurity very easily along with the motion of oil near the main lip of seal ring, seal ring is caused fatal infringement, thereby causes the leakage of parts.Existing seal ring does not have defensive ability/resistance ability to impurity in the oil, and the working life of seal ring is short.
The model utility content
The technical problems to be solved in the utility model provides a kind of seal ring that has impurity barrier structure in the oil; The sealing circle has prolonged the working life of seal ring to the defensive ability/resistance ability that has of impurity in the oil.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: it comprises support frame and seal, and described seal is coating support frame; Described support frame is the L type, and the extending portion inboard that coats the seal of support frame is provided with groove, is with spring ring in this groove, and the extending portion outside is provided with the interior impurity of dust excluder lips, primary seal lip and oil from the bottom up and stops lip.
Further, described seal adopts the rubber material.
Further, described support frame adopts stainless steel.
The utility model stops by impurity in the oil and the improvement of procheilon structure meets present service condition, has improved the defensive ability/resistance ability to impurity in the oil, has prolonged the working life of seal ring.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a working state schematic representation of the present utility model.
Embodiment
The utility model comprises stainless steel support frame 1 and rubbery sealed body 2, and described rubbery sealed body 2 envelopes stainless steel support frame 1; Described stainless steel support frame 1 is the L type, extending portion 21 inboards that envelope the rubbery sealed body 2 of stainless steel support frame 1 are provided with groove 211, be with spring ring 212 in this groove 211, extending portion 21 outsides are provided with the interior impurity of dust excluder lips 213, primary seal lip 214 and oil from the bottom up and stop lip 215.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
