The high-speed zero-escape hydraulic cylinder has the advantages of simple and compact structure, low cost, long service life and wide application.
Description
Technical field
The utility model is mainly concerned with the hydraulic equipment field, refers in particular to a kind of oil hydraulic cylinder.
Background technique
Along with the fast development of hydraulic pressure industry, more and more higher to the requirement of oil hydraulic cylinder, at a high speed, zero reveal, can bear the developing direction that big lateral force oil hydraulic cylinder has become the oil hydraulic cylinder industry, also require oil hydraulic cylinder can adapt to bad working environment simultaneously.In high speed hydraulic cylinder, the oil hydraulic cylinder guide sleeve adopts the copper sheathing guiding at present, and primary seal adopts one this special envelope with the U-shaped circle, perhaps this special envelope of twice.Copper sheathing has that friction factor is low, wear resistance good, good heat resistance, can bear bigger advantages such as lateral force, in the guiding of oil hydraulic cylinder guide sleeve is used more and more widely.Si Te envelope is the important seal element in the high speed hydraulic cylinder, and U-shaped circle frizing preferably prevents to leak effectively, has also obtained utilization more and more widely in the guide sleeve sealing.But because the high-speed motion of piston rod, frictional heat easily produces metal impurities, and the impurity in the hydraulic oil also enters between copper sheathing and the piston rod easily simultaneously, quickens the wearing and tearing of copper sheathing and piston rod, reduces guide effect; Above-mentioned sealing configuration causes easily and leaks simultaneously.
In existing oil hydraulic cylinder guide sleeve, in the piston rod rapid movement, and bigger lateral force is arranged, continuous frictional heat between piston rod and the copper sheathing, be easy to produce metal impurities, pull piston rod, the wearing and tearing copper sheathing pollutes hydraulic oil, bring very serious harm, and guide ring can not bear bigger lateral force, is easy to be damaged by pressure, loses leading role.Simultaneously, in existing high-speed motion oil hydraulic cylinder, how employing this spy's envelope 7 together as shown in Figure 1 is with U-shaped seal ring 9 in the guide sleeve sealing, or this spy of twice seals 7 as shown in Figure 2, but all can not reach the purpose of zero leakage, causes the pollution of working environment.
The model utility content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides a kind of simple and compact for structure, with low cost, long service life, the high speed zero applied widely oil hydraulic cylinder that leaks.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of high speed zero oil hydraulic cylinder that leaks, comprise cylinder barrel and be installed in cylinder barrel interior piston rod, copper sheathing and guide sleeve, described guide sleeve is sheathed on the outer surface of piston rod, is provided with copper sheathing between the outer surface of described piston rod and the guide sleeve, it is characterized in that: described copper sheathing is provided with receives dirty ring.
As further improvement of the utility model:
Described guide sleeve is provided with twice this special envelope and U-shaped seal ring between piston rod.
The tail end of described guide sleeve is provided with detachable gland.
Be provided with guide ring between described guide sleeve and the piston rod.
Be provided with dust ring between described guide sleeve and the piston rod.
Described copper sheathing links to each other by marking closely screw with guide sleeve.
Compared with prior art, advantage of the present utility model just is:
1, the high speed zero of the present utility model oil hydraulic cylinder that leaks, simple and compact for structure, with low cost, not only can be applied to high-speed motion and big lateral force oil hydraulic cylinder, also prolong the life-span of oil hydraulic cylinder and reached zero purpose of revealing;
2, the utility model is equipped with on the guide sleeve copper sheathing and receives dirty ring, can absorb impurity effectively, these impurity are piston rod high-speed motion and the metal impurities of lateral force generation and the impurity in the hydraulic fluid, thereby well protect piston rod and copper sheathing, reduce the wearing and tearing of piston rod and copper sheathing, prolong the working life of oil hydraulic cylinder;
3, the utility model is equipped with this special envelope of twice with the U-shaped circle on guide sleeve, Si Te envelope has that friction is little, static state and advantage such as dynamic airtightness is good, series seal is effective, it is the important seal element in the high speed hydraulic cylinder, and the U-shaped circle has frizing ability preferably, this sealing configuration can adapt to the job requirement of high-speed motion oil hydraulic cylinder, can reach zero purpose of revealing again, help protecting the operate outside environment of oil hydraulic cylinder;
4, the utility model is made gland and guide sleeve split type, is because the U-shaped circle is easily aging in high-speed motion, needs periodic replacement, and this split-type structural, can not dismantle whole guide sleeve, change the U-shaped circle under the situation of gland and only dismantle, convenient and swift.
