Description
Technical field
The utility model belongs to oil enveloping structure technical field, and in particular to a kind of card die mould oil enveloping structure.
Background technique
Oil sealing, the i.e. sealing device of lubricating oil are that fluid or solid particle are revealed from the binding site of device in order to prevent,
And the part of the internal influence inner components of the invasion mechanical equipment such as impurity, moisture for preventing outside, thus oil pocket and outside
Boundary's isolation, the structure of the oil sealing sealing part of the prior art is relatively simple, the structures such as rubber ring is mostly used, although may be implemented to grasp
Make, but the sealing performance of its oil sealing is relatively limited, and stability in use is difficult to ensure, so applicability and practicability are certain
It is restricted in degree.
Summary of the invention
Reasonable and strong applicability the card die mould oil enveloping structure the purpose of the utility model is to provide a kind of structure setting.
The technical solution for realizing the utility model aim is a kind of card die mould oil enveloping structure, including rubber oil sea ontology,
It is dust-proof to ring that the first sealing lip, the second sealing lip and outside are successively fixed on the inner wall of the rubber oil sea ontology, described
It is fixed with metallic framework on the outside of one end of rubber oil sea ontology, being fixed with section in the lateral surface of the metallic framework is arc
Ring is compressed, is fixed in the lateral surface of the rubber oil sea ontology and compresses groove, the groove that compresses is in the second sealing lip
Outside, the opening diameter for compressing ring are less than the diameter for compressing groove, are provided at least one buffering on ring in described compress
Strip groove, the end card for compressing ring, which is pressed in described compress, rides over the second sealing lip on the surface of shaft.
It is fixed with clamp ring on the outside of the rubber oil sea ontology, is fixed with ring in the lateral surface of the rubber oil sea ontology
Clevis slot, the annular clip slot are in the dust-proof outside to ring in outside, and the clamp ring is caught in fixed in the annular clip slot.
The internal diameter of the clamp ring is less than the diameter of annular clip slot and is greater than the outer diameter of shaft.
It is described to compress the carbon steel ring that ring is 1-2mm, it is integrally formed on the inner ring side for compressing ring and section is circle
Inside edge.
The utility model has the effect of positive: the structure setting of the utility model is reasonable, be provided with compress ring and
It compresses and is provided at least one buffering strip groove on ring, advantageously ensure that the first sealing lip, the second sealing of rubber oil sea ontology
The dust-proof ring that supports of lip and outside closely rides over the surface of shaft, to guarantee the reliability of oil sealing, strong applicability and practical
Property is good.
Detailed description of the invention
In order to be more likely to be clearly understood the content of the utility model, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, in which:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the concrete structure schematic diagram for compressing ring of the utility model.
Specific embodiment
(embodiment 1)
Fig. 1 and Fig. 2 shows a kind of specific embodiment of the utility model, and wherein Fig. 1 is the structure of the utility model
Schematic diagram；Fig. 2 is the concrete structure schematic diagram for compressing ring of the utility model.
Fig. 1 and Fig. 2, a kind of card die mould oil enveloping structure, including rubber oil sea ontology 1 are seen, in the rubber oil sea ontology
It is dust-proof to ring 4 that the first sealing lip 2, the second sealing lip 3 and outside are successively fixed on inner wall, the one of the rubber oil sea ontology
End outside is fixed with metallic framework 5, is fixed with section in the lateral surface of the metallic framework and compresses ring 6 for arc, described
The lateral surface of rubber oil sea ontology, which is fixed with, compresses groove 7, the outside for compressing groove and being in the second sealing lip, described to compress
The opening diameter of ring is less than the diameter for compressing groove, is provided at least one buffering strip groove 8 on ring in described compress, is provided with
Strip groove is buffered, so as to so that a range can be unfolded by compressing ring, facilitate installation to fix, the end card pressure for compressing ring
On the surface for compressing and the second sealing lip being made to ride over shaft in groove.
It is fixed with clamp ring 9 on the outside of the rubber oil sea ontology, is fixed in the lateral surface of the rubber oil sea ontology
Annular clip slot 10, the annular clip slot are in the dust-proof outside to ring in outside, and the clamp ring is caught in fixed in the annular clip slot.
The internal diameter of the clamp ring is less than the diameter of annular clip slot and is greater than the outer diameter of shaft.
It is described to compress the carbon steel ring that ring is 1-2mm, it is integrally formed on the inner ring side for compressing ring and section is circle
Inside edge 11.
The structure setting of the utility model is reasonable, is provided with and compresses ring and be provided at least one buffering on compressing ring
Strip groove advantageously ensures that the dust-proof ring that supports of the first sealing lip, the second sealing lip and outside of rubber oil sea ontology closely rides over
The surface of shaft, to guarantee the reliability of oil sealing, strong applicability and practicability is good.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.And the obvious changes or variations that these connotations for belonging to the utility model are extended out still fall within it is practical
Novel protection scope.
