Abstract
The invention discloses a kind of hydraulic cylinder sealing ring, including sealing ring body, set fluted on the madial wall of the sealing ring body, dust ring is provided with groove, top rib and bottom rib are provided with the inwall of sealing ring body.The present invention has the advantages of structure design is simple, service life is long, pass through the cooperation of sealing ring body and dust ring, realize to the multi-layer sealed of piston rod, it ensure that the airtight quality of piston rod, simultaneously fat groove is provided with dust ring, facilitate the flowing of lubricant grease, so as to increase the service life of dust ring.
Description
Technical field
The present invention relates to sealing ring technical field, specifically a kind of hydraulic cylinder sealing ring.
Background technology
Revolving hydraulic rotation all be present in each industrial circle such as engineering machinery, building machinery and automobile equipment.It is used
In bar, axle, swivel joint for being sealed with rotation or oscillating motion etc., it is that one kind can bear pressure at both sides or alternating pressure is made
The rotating seal ring of two-way function.At present, because the use environment of sealing ring is severe, so in use, sealing
Circle is easily subject to dirt contamination, so as to aggravate the abrasion of sealing ring, influences the sealing effectiveness of sealing ring.Therefore in the market needs
A kind of sealing ring of complex, service life length.
The content of the invention
According to above the deficiencies in the prior art, the technical problems to be solved by the invention are to propose a kind of hydraulic cylinder sealing
Circle.
The present invention is solved its technical problem and realized using following technical scheme：
A kind of hydraulic cylinder sealing ring, including sealing ring body, set on the madial wall of the sealing ring body it is fluted,
Dust ring is provided with groove, top rib and bottom rib are provided with the inwall of sealing ring body.
Grease storing chamber is provided with described in said apparatus in groove.
The ratio of the volume of groove described in said apparatus and the volume of grease storing chamber is 5:1.
Groove described in said apparatus and the junction of sealing ring inner body wall are provided with reinforcement.
Elastic portion is provided with bottom rib described in said apparatus.
The cross section of dust ring described in said apparatus is circle.
Fat groove is evenly arranged with described in said apparatus on dust ring.
Sealing ring body described in said apparatus is provided with enhancement layer.
The beneficial effects of the invention are as follows：
The present invention has the advantages of structure design is simple, service life is long, by the cooperation of sealing ring body and dust ring,
Realize to the multi-layer sealed of piston rod, ensure that the airtight quality of piston rod, while fat groove is provided with dust ring, it is convenient
The flowing of lubricant grease, so as to increase the service life of dust ring.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below by the description to embodiment, the shape of for example involved each component of embodiment of the invention, structure
Make, the mutual alignment between each several part and annexation, the effect of each several part and operation principle, manufacturing process and the side of operating with
Method etc., is described in further detail, completeer to help those skilled in the art to have inventive concept of the invention, technical scheme
Whole, accurate and deep understanding.
As shown in figure 1, a kind of hydraulic cylinder sealing ring, including sealing ring body 1, the madial wall of the sealing ring body 1
It is upper that fluted 1a is set, dust ring 2 is provided with groove 1a, top rib 1b is provided with the inwall of sealing ring body 1 with
Portion rib 1c.
Grease storing chamber 1d is provided with groove 1a, grease storing chamber 1d is used for storing lubricating grease, for reducing sealing ring body 1 with living
The coefficient of friction of stopper rod, add the service life of sealing ring.
The ratio of groove 1a volume and grease storing chamber 1d volume is 5:1, this volume fraction is optimal proportion, is not being influenceed
While the structural strength of sealing ring body 1, there is the volume of larger depot fat again.
Groove 1a and the inwall of sealing ring body 1 junction are provided with reinforcement, for increasing the structure of sealing ring body 1
Intensity.
Elastic portion is provided with the rib 1c of bottom, bottom rib 1c can be made preferably to be fitted on the outer wall of piston rod.
The cross section of dust ring 2 is circle, and manufacturing cost is low.
Fat groove 2a is evenly arranged with dust ring 2, facilitates the flowing of lubricant grease, so as to increase the use of dust ring 2
Life-span.
Sealing ring body 1 is provided with enhancement layer, increases the stability of sealing ring.
In use, sealing ring body 1 is arranged in hydraulic cylinder, in hydraulic cylinder works, piston rod is along sealing ring body 1
Inwall slide, and in the sliding process of piston rod, top rib 1b stops the dirt on piston rod, dust ring 2 at first
Positioned at top rib 1b bottom, bottom rib 1c top, it can further stop dirt, bottom rib 1c is then used for final
Stop dirt, prevent from polluting the fluid in hydraulic cylinder, and after dust ring 2 wears excess, dust ring 2 can be carried out more
Change, improve the service life of sealing ring.
The present invention is exemplarily described above, it is clear that present invention specific implementation is not subject to the restrictions described above,
As long as employing the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress, or not improved this is sent out
Bright design and technical scheme directly applies to other occasions, within protection scope of the present invention.The protection of the present invention
Scope should be determined by the scope of protection defined in the claims.
