Abstract
The utility model discloses a seal piece used for a reciprocal moving part oil seal. The seal piece comprises an annular body. The seal piece is characterized in that the seal piece further comprises a framework, the cross section of the annular body comprises a horizontal portion located on the outer side and a flexural portion located on the inner side, the horizontal portion is connected with the flexural portion through a connecting portion, the flexural portion extends backwards to form an anti-dust lip which is arranged in an inclined mode, the flexural portion extends forward to form a seal lip which is arranged in an inclined mode, a seal position is formed between the anti-dust lip and the seal lip, the framework is arranged inside the annular body, and the thickness of connecting portion colloid is equal to the thickness of the vertical section of the framework. The seal piece solves the problems that most seal pieces of reciprocal moving part oil seals are pure colloid seal pieces, the overall strength is low, the thickness of colloid which wraps frameworks is too large, colloid layers are very easy to damage, and the service lives of the seal pieces are influenced. The seal piece used for the reciprocal moving part oil seal is simple in structure, high in intensity, not prone to abrasion, and long in service life.
Description
Technical field
The utility model relates to a kind of Sealing, particularly relates to a kind of Sealing for the reciprocating member oil sealing.
Background technique
Sealing is exactly the parts that seal, rise the gas leakage leakage of oil that prevents from leaking parts.The Sealing that is used at present the reciprocating member oil sealing adopts pure colloid Sealing, and whole intensity is lower, when the parts of the repeatedly motion that is sealed with pressure often because insufficient strength, thereby cause the damage of Sealing, working life is shorter.Simultaneously less at some pressure, reciprocating speed is very fast, and in the more parts of times of exercise, if the colloid thickness of wrapping frame is blocked up, the very easy damage of glue-line affects working life of Sealing.Sealing outside end face is because larger with the pilot hole area of contact in addition, and also very easy wearing and tearing cause scrapping of whole Sealing, bring than large economy and lose.
The model utility content
For the pure colloid Sealing of the many employings of Sealing that solves reciprocating member oil sealing in the prior art, whole intensity is lower, and the colloid thickness of wrapping frame is blocked up, the very easy damage of glue-line, affect the problem of seal durability, it is a kind of simple in structure that the utility model provides, and intensity is high, not easy to wear, the Sealing that is used for the reciprocating member oil sealing of long service life.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of Sealing for the reciprocating member oil sealing, comprise ring body, it is characterized in that: also comprise skeleton, described ring body cross section comprises the horizontal part that is positioned at the outside and is positioned at inboard deflection division, described horizontal part is connected by joint with deflection division, described deflection division extends back and forms the dust excluder lips that is obliquely installed, described deflection division extends to form the sealing lip that is obliquely installed to the front side, form sealing station between described dust excluder lips and the sealing lip, described skeleton cross section is L-type, comprise interconnective horizontal segment and vertical section, described horizontal segment inserts the ring body horizontal part, and described vertical section extend into deflection division by joint, described horizontal part, deflection division and joint adopt form by once with rubber, and vertically section thickness is identical with skeleton for described joint colloid thickness.
Aforesaid a kind of Sealing for the reciprocating member oil sealing is characterized in that: chamfering before ring body outboard end face forward position forms.
Aforesaid a kind of Sealing for the reciprocating member oil sealing is characterized in that: chamfering after ring body outside end face rear positions forms.
Aforesaid a kind of Sealing for the reciprocating member oil sealing is characterized in that: the outside end face between described front chamfering and the rear chamfering is the waveform end face.
Aforesaid a kind of Sealing for the reciprocating member oil sealing is characterized in that: described skeleton adopts ferrous material to make.
The beneficial effects of the utility model are: the utility model is used for the Sealing of reciprocating member oil sealing, described skeleton horizontal segment inserts the ring body horizontal part, described skeleton vertically section extend into deflection division by joint, like this so that the Sealing bulk strength greatly improve, replaced pure glue spare product, prolong working life.Vertically section thickness is identical with skeleton for joint colloid thickness simultaneously, skeleton is tightly wrapped, joint encapsulate force bearing point is near skeleton like this, like this in the little to-and-fro motion process of pressure, the Sealing enclasping force is just less, frictional force is also less, and it is fast to adapt to movement velocity, reciprocating friction often.The utility model face that will contact with pilot hole is designed to the waveform end face in addition, has reduced the area of contact with pilot hole, and prolong working life.
Description of drawings
Fig. 1 is the seal configuration schematic representation that the utility model is used for the reciprocating member oil sealing.
Fig. 2 is A part structure for amplifying schematic representation among Fig. 1.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of Sealing for the reciprocating member oil sealing, comprise ring body 1 and skeleton 2, described ring body 1 cross section comprises the horizontal part 4 that is positioned at the outside and is positioned at inboard deflection division 3, described horizontal part 4 is connected by joint 5 with deflection division 3, described deflection division 3 extends back and forms the dust excluder lips 6 that is obliquely installed, and described deflection division 3 extends to form the sealing lip 7 that is obliquely installed to the front side, forms sealing station 8 between described dust excluder lips 6 and the sealing lip 7.
Described skeleton 2 cross sections are L-type, comprise interconnective horizontal segment 9 and vertical section 10, and described skeleton 2 adopts ferrous materials to make.Skeleton 2 horizontal segments 9 insert ring body 1 horizontal part 4, described skeleton 2 vertically section 10 extend into deflection division 3 by joint 5, described horizontal part 4, deflection division 3 and joint 5 adopt form by once with rubber, and vertically section 10 thickness are identical with skeleton 2 for described joint 5 colloid thickness.
