Abstract
The utility model relates to the shaft seal technical field in reciprocating movement of a power machine, in particular to a high pressure shock absorber seal ring used in reciprocating movement. The high pressure shock absorber seal ring used in reciprocating movement comprises a framework and a rubber elastomer; wherein, the framework is arranged in the rubber elastomer; a polyfluortetraethylene ring is compounded above the rubber elastomer; the polyfluortetraethylene ring shrinks upwards and inwards to form a main seal lip. The utility model adopts sulfuration processing to couple and graft a thin polyfluortetraethylene layer with rubber so as to obtain the composite material of rubber and polyfluortetraethylene. The composite material is applied to the shock absorber seal ring, taking full advantage of the self-lubricating property of polyfluortetraethylene to meet the demand of wearability and making use of the elasticity of the rubber to meet the requirement of the following motion of the seal lip. Compared with conventional pure rubber shock absorber oil, the high pressure shock absorber seal ring is greatly prolonged in service life.
Description
Technical field
The utility model relates to reciprocating shaft technical field of sealing technology in the dynamic power machine, relates in particular to a kind of reciprocating high-pressure shock absorber seal ring that is used for.
Background technique
The vibration damper seal ring is the core component of vibration damper, and its length in working life has directly determined the life-span of vibration damper.Traditional vibration damper seal ring generally comprises skeleton and rubber elastomer, skeleton is arranged on the rubber elastomer, the inner ring of rubber elastomer is provided with primary seal lip and secondary seal lip, rubber elastomer is all made by gum, because primary seal lip and reciprocating shaft friction factor are big, the friction Temperature Rise height causes the primary seal lip aging, not wear-resisting, make it sealing effect relatively poor, be easy to wearing and tearing.Therefore, it is difficult to bear millions of inferior to-and-fro motion.
Summary of the invention
In order to solve the technological deficiency that above-mentioned vibration damper seal ring exists, the purpose of this utility model provides the vibration damper seal ring of a kind of good seal performance, wear-resisting, ageing-resistant, high life.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind ofly be used for reciprocating high-pressure shock absorber seal ring, comprise skeleton and rubber elastomer, skeleton is arranged in the rubber elastomer, and the compound polytetrafluoroethylene ring that is provided with in rubber elastomer top, polytetrafluoroethylene ring are upwards, toe-in forms the primary seal lip.As preferably, the bore of above-mentioned primary seal lip can be ￠ 3～￠ 500mm.
As preferably, described polytetrafluoroethylene ring is the filled polytetrafluoroethylene material.Described filled polytetrafluoroethylene material is the existing favorable mechanical performance that has, self lubricity, the teflon filled composite materials of corrosion resistance and self-compensating function.As preferably, the thickness of above-mentioned polytetrafluoroethylene ring is 0.10mm～15mm.
As preferably, the below of above-mentioned rubber elastomer is provided with dustproof lip.The bore of dustproof lip can be ￠ 3～￠ 500mm.
As a kind of selection, above-mentioned rubber elastomer has extended to form dust ring downwards, and dust ring is to the described dustproof lip of projecting inward formation.
Select as another kind, above-mentioned dustproof lip is downward by one, the filled polytetrafluoroethylene ring of toe-in forms the compound below that is arranged on rubber elastomer of described filled polytetrafluoroethylene ring.The thickness of above-mentioned filled polytetrafluoroethylene ring can be 0.1～5mm.
The utility model obtains rubber and polytetrafluoroethylplastic plastic composite material after having adopted sulfuration process that teflon thin layer and rubber are carried out coupling, graft reaction.Composite rubber-plastic material not only has the material behavior of teflon excellence, the high elastic index that has both simultaneously rubber again, be applied to the vibration damper seal ring, make full use of the teflon self lubricity and satisfied wear-resisting requirement, utilize the elasticity of rubber again, reach lip servo-actuated requirement, compare with traditional gum shock absorber fluid, improve working life greatly.Other performance of teflon has improved the possibility that seal ring is applicable to the working condition that other is harsh greatly.According to test, there is not noticeable wear, favorable sealing property through seal ring after 5,000,000 times the to-and-fro motion.
