Abstract

The invention discloses a sealing element for an oil seal of a reciprocating moving part. The sealing element comprises an annular body, and is characterized by further comprising a skeleton, wherein the cross section of the annular body comprises a horizontal part at the outer side and a flexible part at the inner side; the horizontal part is connected with the flexible part through a connecting part; the flexible part stretches backwards to form an anti-dust lip which is obliquely arranged; the flexible part stretches towards the front side to form a sealing lip which is obliquely arranged; the anti-dust lip and the sealing lip are arranged in a sealing way; the skeleton is arranged in the annular body; and the colloid of the connecting part is identical to the vertical section of the skeleton in thickness. The sealing element for the oil seal of the reciprocating moving part solves the problems of being relatively low in integral strength and excessively thick in the colloid covering the skeleton such that the colloid layer is quite easy to be damaged and the service life of the sealing piece is affected because a pure colloid sealing piece is generally adopted; and the sealing element for the oil seal of the reciprocating moving part is simple in structure, high in strength, difficult to wear and long in service life.

Description

A kind of Sealing that is used for the reciprocating member oil sealing
Technical field
The present invention relates to a kind of Sealing, particularly relate to a kind of Sealing that is used for the reciprocating member oil sealing.
Background technique
Sealing is exactly the parts that seal, rise the gas leakage leakage of oil that prevents to leak parts.The Sealing that is used for the reciprocating member oil sealing at present adopts pure colloid Sealing, and whole intensity is lower, when the parts of the motion repeatedly 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 influences working life of Sealing.Sealing outside end face is because bigger 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.
Summary of the invention
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, influence the problem of seal durability, the invention provides a kind of simple in structure, the intensity height, 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, the technical solution used in the present invention is:
A kind of Sealing that is used 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 the 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 that is used for the reciprocating member oil sealing is characterized in that: the portion position forms preceding chamfering in face of the ring body outboard end.
Aforesaid a kind of Sealing that is used for the reciprocating member oil sealing is characterized in that: the end face rear positions forms the back chamfering in the ring body outside.
Aforesaid a kind of Sealing that is used for the reciprocating member oil sealing is characterized in that: the outside end face before described between chamfering and the back chamfering is the waveform end face.
Aforesaid a kind of Sealing that is used for the reciprocating member oil sealing is characterized in that: described skeleton adopts ferrous material to make.
The invention has the beneficial effects as follows: the present invention 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, make the Sealing bulk strength improve greatly like this, 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, it is just less that Sealing is held power tightly, frictional force is also less, and it is fast to adapt to movement velocity, reciprocating friction often.The present invention's 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 present invention is used for the reciprocating member oil sealing.
Fig. 2 is an A part structure for amplifying schematic representation among Fig. 1.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of Sealing that is used 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 the 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.
Chamfering 11 before the portion position forms in face of ring body 1 outboard end forms back chamfering 21 in ring body 11 outside end face rear positions.Outside end face before described between chamfering 11 and the back chamfering 12 is a waveform end face 13.
The present invention is used for the Sealing of reciprocating member oil sealing, described skeleton 2 horizontal segments 9 insert ring bodies 1 horizontal part 4, and described skeleton 2 vertically section 10 extend into deflection division 3 by joint 5, makes the Sealing bulk strength improve greatly like this, replaced pure glue spare product, prolong working life.Vertically section 10 thickness are identical with skeleton 2 for joint 5 colloid thickness simultaneously, skeleton 2 is tightly wrapped, joint 5 encapsulate force bearing points are near skeleton 2 like this, like this in the little to-and-fro motion process of pressure, it is just less that Sealing is held power tightly, frictional force is also less, and it is fast to adapt to movement velocity, reciprocating friction often.The present invention's face that will contact with pilot hole is designed to waveform end face 13 in addition, has reduced the area of contact with pilot hole, and prolong working life.
