Abstract
The utility model discloses a kind of split type sealing rings of hydraulic cylinder, including oil sealing ontology and retaining ring, the oil sealing ontology is integrally formed with the first skeleton, first skeleton and the second skeleton are connected through a screw thread fixation, oil sealing ontology, spring and retaining ring are installed in the cavity constituted between the first skeleton and the second skeleton three, retaining ring is buckled in spring peripheral, oblique outwardly extending dust cover is additionally provided on oil sealing ontology, it is connected on first skeleton and the second skeleton at least through three bolt fastenings, the section of first skeleton is F font, the section of second skeleton is L-shaped, the retaining ring is annulus, two retaining rings are at least set outside spring, the retaining ring section is U-shaped, the recess of retaining ring matches with spring, the spring is garter springs or tension spring.The present apparatus increases the second skeleton of retaining ring and its limit, so that the position of spring is not susceptible to change, spring, which can be stablized, keeps pressing force of the sealing lip to axis by being further improved.
Description
Technical field
The utility model relates to the designs of the structure of sealing ring, more particularly to a kind of split type sealing ring of hydraulic cylinder.
Background technique
In the prior art, sealing ring is usually used to complete in the seal operation between hydraulic cylinder and piston rod, adopts
With integrally formed cyclic structure, this sealing ring is mainly the gap filled between piston rod and hydraulic cylinder, then by
It is deformed under piston rod and the compressing of both cylinder bodies, to realize to the sealing between hydraulic cylinder and piston rod.The structure type
Sealing ring integral, flexible coefficient is bigger than normal, and sealing ring will necessarily be made to increase the frictional resistance that piston rod applies, be unfavorable for hydraulic
The work performance of device.Meanwhile hydraulic cylinder holds piston rod tightly by dustproof lip on the inside of dust-proof seal ring in working in reciprocating mode,
Primary seal, support ring etc. are destroyed to prevent foreign matter from entering hydraulic system, sealing ring integral, flexible coefficient is excessive, and dust-proof effect then can
It reduces.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of split type sealing of hydraulic cylinder
Circle, the device are designed by split type structure, increase the overall structural strength of sealing ring, the coefficient of elasticity of sealing ring is in reasonable model
In enclosing, dust-proof and sealing using effect is taken into account.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of split type sealing of hydraulic cylinder
Circle, including oil sealing ontology and retaining ring, the oil sealing ontology are integrally formed with the first skeleton, and the first skeleton and the second skeleton are logical
It crosses threaded connection to fix, spring and retaining ring is installed in the cavity constituted between oil sealing ontology, the first skeleton and the second skeleton three,
Retaining ring is buckled in spring peripheral, and oblique outwardly extending dust cover is additionally provided on oil sealing ontology.
Further, it is connected on the first skeleton and the second skeleton as described above at least through three bolt fastenings.
Further, the section of the first skeleton as described above is F font, and the section of the second skeleton is L-shaped.
Further, retaining ring as described above is annulus, and two retaining rings are at least arranged outside spring.
Further, retaining ring section as described above is U-shaped, and recess and the spring of retaining ring match.
Further, spring as described above is garter springs or tension spring.
Compared with prior art, the utility model has the beneficial effects that the present apparatus is increased by further seperated Curve guide impeller
Add the second skeleton of retaining ring and its limit so that the position of spring is not susceptible to change, spring can stablize keep sealing lip to
The pressing force of axis, sealing effect is good, and service life extends.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
The label in accompanying drawing is: 1. oil sealing ontologies；2. the first skeleton；3. dust cover；4. spring；5. retaining ring；6. the second bone
Frame.
Specific embodiment
Be described in detail below with reference to embodiment referring to attached drawing, so as to the technical characteristics of the utility model and advantage into
Row deeper into annotation.
As shown in Figure 1, a kind of split type sealing ring of hydraulic cylinder of the utility model, including oil sealing ontology 1 and retaining ring
5, the oil sealing ontology 1 is integrally formed with the first skeleton 2, and the first skeleton 2 and the second skeleton 6 are connected through a screw thread fixation,
Spring 4 and retaining ring 5 are installed, retaining ring 5 buckles in the cavity constituted between 6 three of oil sealing ontology 1, the first skeleton 2 and the second skeleton
In 4 periphery of spring, oblique outwardly extending dust cover 3 is additionally provided on oil sealing ontology 1.
Further, first skeleton 2 is connected on the second skeleton 6 at least through three bolt fastenings, and bolt is equal
Cloth is on the circumference of the second skeleton 6.The section of first skeleton 2 is F font, and the section of the second skeleton 6 is L-shaped, is
It is easily installed bolt, the length of bolt is not more than the cavity spacing of the first skeleton 2, while bolt is completely through the first skeleton 2
With the second skeleton 6.
In addition, the retaining ring 5 can choose as annulus shape, two retaining rings 5 are at least set outside spring 4, can also be selected
Select 5 section of retaining ring be it is U-shaped, recess and the spring 4 of retaining ring 5 match.The spring 4 be garter springs 4 or tension spring,
Pressing force of the sealing lip to axis can be improved in spring 4, plays a part of to maintain this pressing force.1 lip end (dust cover 3 one of oil sealing ontology
Side) it is made into oblique wedge shape, on end pressing axis surface, play a part of to seal fluid.
In utility model device, the components such as integral molding techniques, spring 4, tapping and bolt for being related to are
The prior art or material, affiliated technical staff according to required product type and specification, can directly from market purchase or
It is tailor-made.
Clear, complete description is carried out to the utility model by the technical solution in above embodiments, it is clear that described
Embodiment be the utility model a part embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
