Abstract
The utility model discloses a kind of modified model oil cylinder sealing structure, including piston rod, cylinder body, fairlead, fairlead outer circumference surface is provided with lip, lip is mounted on the end face of cylinder body, and is screwed by nut cap；It is provided with guide ring on fairlead outer circumference surface, inner peripheral surface is provided with O RunddichtringO, Yx sealing ring, this special envelope, dust ring.This utility model improves the version of sealing ring, is additionally arranged Yx sealing ring and Si Te envelope.Yx sealing ring can be used for the sealing of reciprocating mechanism, and it relies on lip that coupled face is in close contact and produces under pressure the purpose that bigger contact pressure reaches to seal；Si Te envelope is then to utilize its bladed to seal structure and its good resorption effect and anti-extrusion performance, reduces the fine film pulled out from oil pocket by piston rod, thus reduces the leakage rate of hydraulic oil.By above-mentioned O RunddichtringO, Yx sealing ring, this special envelope three's seal combination, the slip of oil cylinder can be substantially reduced.
Description
Technical field
This utility model relates to cylinder seal field, a kind of follow-on oil cylinder sealing structure.
Background technology
In prior art, the cylinder seal pair overwhelming majority uses the seal form such as the sealing of O type, Y shape sealing, these sealing pairs
Overwhelming majority operating condition can be met.But under some special operation condition, the power that cylinder piston rod bears is suddenly big or suddenly small, and oil cylinder makes
It is inevitably generated violent vibration and impact during with, thus causes the O RunddichtringO on fairlead to be extruded sealing
, there is the phenomenon that oil cylinder leaks in groove.
Summary of the invention
The purpose of this utility model is to provide a kind of follow-on oil cylinder sealing structure, close to solve oil cylinder in prior art
The leakage problem that envelope is secondary.
This utility model is achieved by the following technical solution:
A kind of modified model oil cylinder sealing structure, including piston rod, cylinder body, fairlead, described fairlead outer circumference surface sets
Being equipped with lip, described lip is mounted on the end face of cylinder body, and is screwed by nut cap；Arrange on described fairlead outer circumference surface
There is guide ring, inner peripheral surface is provided with O RunddichtringO, Yx sealing ring, this special envelope, dust ring.
Preferred as one, the inner peripheral surface of described fairlead is provided with 2 O RunddichtringOs, 1 Yx sealing ring, 1
Si Te envelope, 1 dust ring.
Preferred as one, described nut cap is additionally provided with backing-up screw.
Compared with prior art, the beneficial effects of the utility model are:
1, the bonded lip that is revised as of legacy card being directed to set compresses connection, on the premise of ensureing oil cylinder stability,
The barrel of cylinder body one end is processed one section of fine thread, is coated with anaerobism fat at screw thread, and is equipped with the nut cap after screwing, add cylinder
The sealing of cap.
2, monoblock type fairlead changes embedded fairlead into, fairlead material uses the high-abrasive materials such as bronze, can avoid
There is pull-cylinder phenomena.
3, improve the form of sealing ring, be additionally arranged Yx sealing ring and Si Te envelope.Yx sealing ring is mainly used in back and forth transporting
The sealing of motivation structure, its dependence lip is in close contact and produces under pressure bigger contact pressure and reaches coupled face
The purpose sealed；Si Te envelope is then to utilize its bladed to seal structure and its good resorption effect
Fruit and anti-extrusion performance, reduce the fine film pulled out from oil pocket by piston rod, thus reduce the leakage of hydraulic oil
Amount.By above-mentioned O RunddichtringO, Yx sealing ring, this special envelope three's seal combination, the slip of oil cylinder can be substantially reduced.
Accompanying drawing explanation
Fig. 1 is this utility model structure chart.
Wherein: 1, piston rod, 2, cylinder body, 3, nut cap, 31, backing-up screw, 4, fairlead, 5, O RunddichtringO, 6, guide
Ring, 7, Yx sealing ring, 8, lip, 9, this special envelope, 10, dust ring.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention the present invention will be further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit this utility model.
As it is shown in figure 1, present embodiment discloses a kind of modified model oil cylinder sealing structure, including piston rod 1, cylinder body 2, guide
Set 4, is at improvement, described fairlead 5 outer circumference surface is provided with lip 8, and described lip 8 is mounted on the end face of cylinder body 2,
And screwed by nut cap 3；It is provided with guide ring 6 on described fairlead 4 outer circumference surface, inner peripheral surface is provided with O type and seals
Circle 5, Yx sealing ring 7, this special envelope 9, dust ring 10.
As a kind of preferred embodiment, the inner peripheral surface of described fairlead 4 is provided with 5,1 Yx of 2 O RunddichtringOs close
This 9,1 dust ring 10 of special envelope of seal 7,1.
This utility model improves the version of sealing ring, is additionally arranged Yx sealing ring and Si Te envelope.Yx sealing ring can
For the sealing of reciprocating mechanism, it relies on lip be in close contact coupled face and produce bigger under pressure
Contact pressure reaches the purpose sealed；Si Te envelope is then to utilize its bladed seal structure and its good resorption effect and resist crowded
Go out performance, reduce the fine film pulled out from oil pocket by piston rod, thus reduce the leakage rate of hydraulic oil.Close by above-mentioned O type
Seal, Yx sealing ring, this special envelope three's seal combination, can be substantially reduced the slip of oil cylinder.
Above description is to explanation of the present utility model, is not to restriction of the present utility model, and this utility model is limited
Scope see claim, in the case of this utility model basic conception, this utility model can make other shape
The amendment of formula.
