Description

Bind round pressure type outside framework oil seal body

Technical field

The utility model belongs to oil seal technique field, and in particular to a kind of hoop pressure type outside framework oil seal body.

Background technique

Oil sealing is the mechanical organ for being used to oil sealing, and the component for needing to lubricate in transmission parts is isolated with power output component for it, It is unlikely to allow oil seepage, while is also possible to prevent extraneous dust and entering in lubricating component, internal oil sealing and externally dust-proof, It is in and is widely used in electric appliance, automobile engine and chemical industry, although the oil enveloping structure of the prior art can satisfy one As situation use demand, but it is mostly poor there are mounting stability and the case where be easy to appear loosening, so applicability and Practicability is restricted.

Summary of the invention

And a kind of use reliable and stable hoop pressure type outside framework oil seal reasonable the purpose of the utility model is to provide structure setting Body.

The technical solution for realizing the utility model aim is a kind of hoop pressure type outside framework oil seal body, including rubber oil seal ring, The inner wall both ends of the rubber oil seal ring are respectively fixed with the first sealing lip being inclined outwardly, the second sealing lip, in the rubber Fixed fluted ring, is further fixed on two in the outer ring surface of the rubber oil seal ring and compresses annular groove in the middle part of the outer ring surface of oil seal ring, The outboard end for compressing annular groove and being respectively at the first sealing lip, the second sealing lip, is additionally provided with u tie pressure ring, the u tie The internal diameter of pressure ring is less than the outside of rubber oil seal ring, riser is fixed on the both ends outer wall on the u tie pressure ring, described It is fixed with locking screw holes on riser, is uniformly fixed with arc in the lateral surface of the u tie pressure ring and compresses plate, the u tie pressure Ring be in the groove ring and fixed by tie down screw and the arc compress plate outboard end be pressed on respectively described in support In pressure ring slot.

Ring is compressed integrally formed with the protection that section is disc in the outboard end that the arc compresses plate, the protection compresses Ring, which is pressed on, to be compressed in annular groove.

Annulus protrusion is fixed in the middle part of the inner wall of the rubber oil seal ring, the degree height of the annulus protrusion is close in first Height of the height of envelope lip and the first sealing lip less than the second sealing lip.

The u tie pressure ring is the carbon steel ring with a thickness of 1-3mm, and the arc compresses plate and u tie pressure ring is integrally formed And thickness is identical.

The utility model has the effect of positive: the structure setting of the utility model is reasonable, and it is convenient to operate, can be effective Guarantee oil sealing performance, while being provided with u tie pressure ring cooperation arc and compressing plate, it is ensured that the reliability of oil sealing is applicable in The strong and practicability of 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 structural schematic diagram of u tie pressure ring in 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 structural schematic diagram of u tie pressure ring in the utility model.

Fig. 1 and Fig. 2, a kind of hoop pressure type outside framework oil seal body, including rubber oil seal ring 1 are seen, in the rubber oil seal ring Wall both ends are respectively fixed with the first sealing lip 2 being inclined outwardly, the second sealing lip 3, in the outer ring surface of the rubber oil seal ring The fixed fluted ring 4 in portion is further fixed on two in the outer ring surface of the rubber oil seal ring and compresses annular groove 5, described to compress annular groove point Other places are additionally provided with u tie pressure ring 6 in the first sealing lip, the outboard end of the second sealing lip, and the internal diameter of the u tie pressure ring is small In the outside of rubber oil seal ring, it is fixed with riser 7 on the both ends outer wall on the u tie pressure ring, it is fixed on the riser There are locking screw holes 8, is uniformly fixed with arc in the lateral surface of the u tie pressure ring and compresses plate 9, the u tie pressure ring is in institute State in groove ring and fixed by tie down screw and the arc compress plate outboard end be pressed on respectively described in compress in annular groove.

Ring 10 is compressed integrally formed with the protection that section is disc in the outboard end that the arc compresses plate, the protection is supported Pressure ring, which is pressed on, to be compressed in annular groove.Ring is compressed using protection, can increase and compress the contact area of annular groove, avoids compressing damage It is bad.

Annulus protrusion 11 is fixed in the middle part of the inner wall of the rubber oil seal ring, the degree height of the annulus protrusion is in first Height of the height of sealing lip and the first sealing lip less than the second sealing lip.

The structure setting of the utility model is reasonable, and it is convenient to operate, and can effectively guarantee oil sealing performance, while being provided with U Shape hoop pressure ring cooperation arc compresses plate, it is ensured that the reliability of oil sealing, strong applicability and practicability are 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.
