Abstract
The utility model relates to a kind of oil cylinder dust ring, comprising: skeleton, wedge shape arc groove, annular ring; The annular sleeve of two sections of different outside diameters that annular ring is structure as a whole; Skeleton is positioned at the big column surface of annular ring, and wedge shape arc groove is opened on the big column of annular ring.The main lip of annular ring has the leaning angle structure of prolongation.This oil cylinder wiper seal performance is better, structure is simple, working stability is reliable, easy for installation.
Description
Technical field
The utility model relates to Sealing technical field, particularly a kind of oil cylinder dust ring.
Background technique
Dust ring is mainly used in hydraulic jack or transmission shaft, and Main Function is that removing reciprocating piston bar is exposed at the dirt such as dust, sand-lime, water accompanying on cylinder outer surface, prevents external dust, water enters sealing mechanism inside.Oil hydraulic cylinder is the important executive component of constructional engineering machinery, and the stability of its quality directly affects working efficiency and the reliability of constructional engineering machinery.But the quality problems of piston rod external leakage in use often occur oil hydraulic cylinder, the main cause of hydraulic cylinder piston rod external leakage is caused to be that rod seal was lost efficacy.In order to prevent dust from entering hydraulic parts inside, the oil hydraulic cylinder worked in the environment that dust is more, between its piston rod and cylinder cap except dress seal ring, separately must fill dust ring.
Summary of the invention
The purpose of this utility model is, provides that a kind of structure is simple, dust-proof effect is excellent for the deficiencies in the prior art, can be widely used in the oil cylinder dust ring of various dust-proof occasion.
A kind of oil cylinder dust ring, comprising: skeleton, wedge shape arc groove, annular ring; Its feature is in the annular sleeve being two sections of different outside diameters that described annular ring is structure as a whole; Skeleton is positioned at the big column surface of annular ring, and wedge shape arc groove is opened on the big column of annular ring.
Described a kind of oil cylinder dust ring, is characterized in that, the main lip of annular ring has the leaning angle structure of prolongation.
The beneficial effects of the utility model are, this oil cylinder wiper seal performance is better, structure is simple, working stability is reliable, easy for installation.The main lip of annular ring adopts the leaning angle structure extended, and can efficiently avoid dust accumulation at the lip place implementing sealing.
Accompanying drawing explanation
Fig. 1 is the axial sectional view of oil cylinder dust ring.
In figure; 1-skeleton; 2-wedge shape arc groove; 3-annular ring; The main lip of 4-.
Embodiment
The technical solution of the utility model is described further by specific embodiment below in conjunction with accompanying drawing.
A kind of oil cylinder dust ring, comprising: skeleton 1, wedge shape arc groove 2, annular ring 3; The annular sleeve of two sections of different outside diameters that annular ring 3 is structure as a whole; Skeleton 1 is positioned at the big column surface of annular ring 3, and wedge shape arc groove 2 is opened on the big column of annular ring 3.The main lip 4 of annular ring 3 has the leaning angle structure of prolongation, can efficiently avoid dust accumulation at the lip place implementing sealing.
Above-described embodiment only for technical conceive of the present utility model and feature are described, can not limit protection domain of the present utility model with this, and all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.The scope of the utility model protection is defined by appended claims and equivalent thereof.
