Abstract
The utility model relates to a wear-resistant self lubrication nitrogen gas spring. A sealing ring of the wear-resistant self lubrication nitrogen gas spring is arranged in a guide sleeve embedded with extreme pressure resistance solid lubricating composite materials, is arranged on a piston rod, is then arranged in a cylinder tube and is provided with a dustproof ring. The wear-resistant self lubrication nitrogen gas spring has the advantages that the friction between friction surfaces of a guide seat and the piston rod is small, in addition, stability and controllability are realized, chemical ingredients are stable in the work temperature range of the nitrogen gas spring, no corrosion is caused on carrying materials, the extreme pressure resistance solid lubricating composite materials are firmly pasted and attached onto the friction surfaces and cannot fall off, high wear resistance and good lubricating performance are realized, the service life of the nitrogen spring can be prolonged, no toxicity and economy are realized, and the process is simple, so the structure of the nitrogen gas spring is more compact.
Description
Technical field
The utility model relates to a kind of wear-resistant self-lubricating nitrogen spring.
Background technique
The structure of at present domestic and international nitrogen spring: a kind of is that the anti-attrition cover is housed between guide sleeve and piston rod, during piston rod movement, leans on anti-attrition cover self-lubrication and anti-attrition.This structure has increased the quantity of part, makes structure not compact.Another kind is between piston rod and guide sleeve, to design lubricating chamber, lubricating oil filling in lubricating chamber, and this mode must adopt the double density seal, and it is long to have strengthened the design base.
Summary of the invention
The purpose of the utility model is: a kind of nitrogen spring that studs with a kind of novel anti-extreme pressure solid lubricating composite material at the guide sleeve endoporus is provided.
It is achieved in that seal ring is contained in the guide sleeve that studs with anti-extreme pressure solid lubricating composite material, and is contained on the piston rod, in the cylinder barrel of packing into then, has refilled dust ring.
The advantage of the utility model is: it is little 1, to stud with between guide sleeve and the piston rod friction surface of anti-extreme pressure solid lubricating composite material friction, and steadily controlled.2, chemical composition stability in the temperature range of nitrogen spring work does not have corrosion to loading material.3, anti-extreme pressure solid profit composite material sticks on the friction surface securely, can not come off.4, very high wear resistance and good lubricity are arranged, can prolong the life-span of nitrogen spring.5, nontoxic, economy, technology is simple, makes the structure of nitrogen spring more compact.

Wherein: 1, cylinder barrel 2, guide sleeve 3, dust ring 4, piston rod 5, anti-extreme pressure solid lubricating composite material 6, seal ring
Embodiment
The utility model is achieved in that anti-extreme pressure solid lubricating composite material 5 is bumped in the guide sleeve 2, with seal ring 6 inside groove of guide sleeve 2 of packing into, and is contained on the piston rod 4, in the cylinder barrel 1 of packing into then, refills dust ring 3.
In the utility model when work,, the to-and-fro motion of piston rod makes in the guide sleeve anti-extreme pressure solid lubricating composite material on rubbing surface, form lubricated good, the firm attachment and the even solid transfer film of covering, has reduced fretting wear significantly.With the carrying out of friction, the solid lubricating composite material of embedding constantly is provided in rubbing surface, when having guaranteed long-time running to the good lubrication of friction pair.Like this, reduced kinematic friction coefficient, made that the wear-resisting property of nitrogen spring is good, long service life.Simultaneously, low to the hardness requirement of piston rod, thus reduced the difficulty of processing of correlated parts, reduce the processing cost of part.
