Abstract
The utility model discloses a novel guide sleeve of a hydraulic cylinder and belongs to the field of hydraulic cylinder guide sleeves. The novel guide sleeve of the hydraulic cylinder comprises a guide sleeve body 1 and two embedded ring sleeves respectively embedded into an inner wall of the guide sleeve body, wherein one ring sleeve is a straight oil groove ring sleeve, the other ring sleeve is a spiral oil groove ring sleeve, the straight oil groove ring sleeve is embedded into an inner wall at one end of the guide sleeve body, and the spiral oil groove ring sleeve is embedded into an inner wall of the other end of the guide sleeve body. A movable sealing mode of the guide sleeve body adopts a glyd ring and a Y ring, and an oil groove is arranged in the front of the Y ring. The static sealing is double-layer O-shaped ring sealing. The novel guide sleeve of the hydraulic cylinder has the advantages of being large in guide span, good in guiding performance, good in abrasion resistance, good in lubricating effect, simple and reliable in structure, good in sealing effect and simple in shape, and simplifying a processing technology.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder novel guide sleeve, belongs to the oil hydraulic cylinder part field, is mainly used in engineering machinery hydraulic cylinder and plays guiding and sealing.
Background technique
At present, domestic oil hydraulic cylinder field component structural is varied, and this key structure spare of guide sleeve adopts monolithic construction mostly, its common supporting form is take rubber material as main supporting ring, supporting band structure, and this structure often needs multiple tracks to support, and per pass supports and all need coordinate the groove of machining high-precision, complex structure, difficulty of processing is large, and easily causes the dress of Sealing to cut, also easily wearing and tearing of supporting ring itself simultaneously.
Summary of the invention
The utility model provides a kind of oil hydraulic cylinder novel guide sleeve, is mainly used in promoting its leading role, has reduced its difficulty of processing, has also guaranteed simultaneously its sealing effect, the shortcoming of having avoided the supporting ring structure to bring.
The utility model is realized with following technological scheme: a kind of oil hydraulic cylinder novel guide sleeve, it comprises the guide sleeve body, embeds two embedded ring sets on the guide sleeve inner body wall respectively, one of them ring set is straight oil groove ring set, another ring set is the helical oil groove ring set, straight oil groove ring set embeds on an end inwall of guide sleeve body, and the helical oil groove ring set embeds on the other end inwall of guide sleeve body.
Motive sealing and static seal combination are adopted in the sealing of described guide sleeve body, and the motive sealing form is that Glais ring adds the Y circle, and drives an oil groove before the Y circle; Static seal adopts the sealing of double layer O-shaped circle.
The utility model beneficial effect is: the guiding span is large, guidance quality good, and wear resistance is good, and high lubricating effect is simple and reliable for structure, has simplified processing technology, and good sealing effect and form are simple.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the I place partial enlarged drawing in Fig. 1;
Fig. 3 is the II place partial enlarged drawing in Fig. 1;
Fig. 4 is the utility model scheme of installation.
In figure: 1, guide sleeve body, 2, straight oil groove ring set, 2.1, straight oil groove, 3, the helical oil groove ring set, 3.1, helical oil groove, 4, Glais ring, 5, the Y circle, 6, oil groove, 7, O shape circle, 8, piston rod, 9, cylinder barrel, 10, gland.
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the oil hydraulic cylinder novel guide sleeve adopt embed respectively on the inwall of guide sleeve body 1 two embedded ring sets composite structure, one of them ring set is straight oil groove ring set 2, have straight oil groove 2.1 thereon, another ring set is helical oil groove ring set 3, has helical oil groove 3.1 thereon; Straight oil groove ring set 2 embeds on an end inwall of guide sleeve body 1, and helical oil groove ring set 3 embeds on the other end inwall of guide sleeve body 1.
As shown in Figure 2, motive sealing and static seal combination are adopted in described guide sleeve body 1 sealing, and the motive sealing form is that Glais ring 4 adds Y circle 5, and drives an oil groove 6 before the Y circle, and static seal adopts 7 sealings of double layer O-shaped circle.During installation, locate by cylinder barrel 9 exterior edge faces and guide sleeve step, rely on gland 10 that it is compressed, utilize its embedded lining to play good leading role.
The present embodiment guide sleeve body 1 is selected certain spheroidal graphite cast iron, in proof strength, has reduced cost; Owing to adopting embedded ring set structure, simplified its structure, reduced difficulty of processing; Embedded ring set adopts Cuprum alloy, both guaranteed its guide effect, utilized again the antiwear characteristic of material, simultaneously according to its working position, two ring sets have adopted multi-form oil groove, have both guaranteed lubrication effect, make again ring set can lead to oil, guarantee the actual effect of sealing, ring set also can play certain sealing effect.Combinations thereof body mode has realized optimizing and combining of material, opens logical oil groove before Y circle, is conducive to its sealing effect, when piston rod 8 retraction, stores certain fluid simultaneously, provides back pressure to the Y circle, prevents that its lip limit from extruding.
