Description
Technical field
The utility model belongs to oil seal technique field, more particularly to a kind of group button floating muddy water oil sealing.
Background technology
Current oil sealing is typically single dust-proof lip type, structure as shown in figure 1, in the structure design of oil sealing, the master of dust excluder lips
It is the entrance for preventing other impurity such as dust, silt to act on, because the product is single dust-proof lip type oil seal（I.e. one dust excluder lips）,
Equipment is under muddy water road and rice field working condition, and dirt exclusion capabilities are limited, and dust, silt are easily entered near primary seal lip,
Primary seal lip can drastically wear and tear because of the presence of impurity, occur oil leakage phenomenon, product failure too early, influence the sealed reliable of product
Property, reduce the service life of product.
The content of the invention
In view of the deficienciess of the prior art, the utility model provides a kind of group button floating muddy water oil sealing, if secondary sealing body,
The entrance of the bulky grains such as stone, silt is prevented, if outer dust excluder lips and interior dust excluder lips, prevents molecule from entering the oily lip of primary seal, carries
High dirt exclusion capabilities, improve service life.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：Group button floating muddy water oil sealing, including
Connection ring and primary seal body are installed, the lower end of primary seal body is connected on the side for installing connection ring, in addition to secondary sealing body and
Elastomer, secondary sealing body is located at primary seal body lower end, and is connected with installing connection ring, and the secondary sealing body, which is provided with, to be used to stop big
The ring-type resistance muddy water groove of particulate matter, secondary sealing body contacts sealing with rotary shaft provided with the side that ring-type hinders muddy water groove, opposite side and
Elastomer phase is contacted.
Further, the primary seal body is provided with the oily lip of primary seal, interior dust excluder lips and outer dust excluder lips.
Further, it is provided with ring spring at the oily lip of the primary seal.
Compared with prior art, the utility model advantage is：Improve the dust-proof lip type oil enveloping structure of existing list, it is close by pair
Seal body and stop the large granular impurities such as stone, the grains of sand, mud, make primary seal body without damage, effectively protect the complete of primary seal body
Whole property, and the effect for passing through elastomer so that secondary sealing body contacts sealing with the lasting elastic tensioning of rotary shaft, prevents lubricating oil
Leakage；Primary seal body is provided with interior dust excluder lips and outer dust excluder lips, and double dust excluder lips stop that molecule enters at the oily lip of primary seal, reduced
Impurity at primary seal oil lip, the oil leakage phenomenon for preventing abrasion of the impurity such as silt to the oily lip of primary seal from causing, so as to extend product
Service life, good dustproof effect.
Brief description of the drawings
Fig. 1 is the structural representation of the dust-proof lip type oil seal of list described in background technology；
Fig. 2 is structural representation of the present utility model.
In figure, A. installs connection ring；B. primary seal body；C. secondary sealing body；D. elastomer；1. primary seal oil lip；2. it is interior dust-proof
Lip；3. outer dust excluder lips；4. hinder muddy water groove；5. ring spring.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is further described to the utility model.
As shown in Fig. 2 group button floating muddy water oil sealing, including connection ring A, primary seal body B, secondary sealing body C and elasticity are installed
Body D, primary seal body B lower end are connected on the side for installing connection ring A, and secondary sealing body C is located at primary seal body B lower ends, and with
Connection ring A connections are installed, secondary sealing body C is produced by the small polyurethane high molecule material of the good hardness great friction coefficient of wearability and made
Make, secondary sealing body C is provided with the ring-type resistance muddy water groove 4 for being used to stop bulky grain thing, prevents the entrance of muddy water, by handstone, the grains of sand,
The large granular impurities such as mud stop outside so that primary seal body B is without damage, effectively protects primary seal body B integrality.
Secondary sealing body C contacts sealing with rotary shaft provided with the side that ring-type hinders muddy water groove 4, and opposite side connects with elastomer D
Touch, elastomer D is used for ensureing that secondary sealing body C contacts sealing with the lasting elastic tensioning of rotary shaft.
Dust-proof effect is improved in order to further, primary seal body B is provided with the oily lip 1 of primary seal, interior dust excluder lips 2 and outer dust excluder lips 3,
Ring spring 5 is provided with primary seal oil lip 1, interior dust excluder lips 2 and outer dust excluder lips 3 stop that molecule enters at the oily lip 1 of primary seal, reduced
Impurity at primary seal oil lip 1, so as to extend the service life of product.
By experiment, oil sealing of the present utility model improves 2-3 times than the oil sealing life-span of Fig. 1 structure, extends making for product
Use the life-span.
In summary, the utility model improves the existing dust-proof lip type oil enveloping structure of list, stops stone, sand by secondary sealing body
The large granular impurities such as grain, mud, make primary seal body without damage, effectively protect the integrality of primary seal body, and pass through bullet
The effect of property body so that secondary sealing body contacts sealing with the lasting elastic tensioning of rotary shaft, prevents the leakage of lubricating oil；Primary seal body
Provided with interior dust excluder lips and outer dust excluder lips, double dust excluder lips stop that molecule enters at the oily lip of primary seal, reduce miscellaneous at the oily lip of primary seal
Matter, the oil leakage phenomenon for preventing abrasion of the impurity such as silt to the oily lip of primary seal from causing, so that the service life of product is extended, it is dust-proof
Effect is good.
Certainly, described above is not that, to limitation of the present utility model, the utility model is also not limited to the example above, this
The those of ordinary skill of technical field, in essential scope of the present utility model, the variations, modifications, additions or substitutions made, all
Protection domain of the present utility model should be belonged to.
