Abstract
The invention relates to the technical field of oil seals, in particular to a lip-shaped framework seal ring with good heat dissipation property. The lip-shaped framework seal ring comprises an L-shaped metal framework and a rubber sealing body which covers an outer side face of the framework, wherein the rubber sealing body is provided with a leaf tail part; a spring groove is formed in the inner side of the leaf tail part; a self-tightening spiral spring is arranged in the spring groove; a trimming surface is arranged on the outer side of the leaf tail part; the rubber sealing body is provided with a sealing lip and anti-skid grains. According to the lip-shaped framework seal ring, the framework is designed on the basis of the pure rubber, so the mounting of the seal ring is greatly facilitated, the assembly and positioning of the seal are guaranteed better, the heat dissipation is good, leakage of lubricating oil of an automobile lubricating system can be avoided, dust can also be sheltered, the sealing effect is guaranteed, the service life of the seal ring is prolonged, and the use requirements are met.
Description
Technical field
The present invention relates to oil seal technique field, the lip backbone sealing ring that especially a kind of thermal diffusivity is good.
Background technique
In vehicle lubricating system, seal ring is installed, traditional seal ring is generally single rubber material or other macromolecular materials, the seal ring of this structure is when matching with housing, its sealing effect not easily ensures, radiating effect is poor, and its material is also easy to follow the string because of aging distortion, and thus working life is shorter, need frequent replacing, affect the operational efficiency of equipment.In addition, because sealing effect is undesirable, very easily make the lubricant medium of lubrication system leak or seepage, can not user demand be met, serious entail dangers to personal safety.
Summary of the invention
The technical problem to be solved in the present invention is: for overcoming above-mentioned Problems existing, provides that a kind of thermal diffusivity is good, the lip backbone sealing ring of good sealing effect.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lip backbone sealing ring, comprise " L " type metal frame and be coated on the rubbery sealed body on skeleton outer side surface, described rubbery sealed body has leaf afterbody, leaf tail inner side has spring ditch, spring ditch is built with self-tightening helical spring, described leaf lateral tail has all and has a shave, and described rubbery sealed body is provided with sealing lip, and described rubbery sealed body is provided with anti-slip veins.
Further, described skeleton has ladder position.
Further, described skeleton material is the iron-clad through antirust treatment, when the seal ring of this structure is that housing matches, can strengthen heat dispersion.
The invention has the beneficial effects as follows, lip backbone sealing ring of the present invention design framework on the basis of gum, greatly facilitate the installation of seal ring, better ensure the assembling and positioning of sealing, thermal diffusivity is good, and the lubricant oil of vehicle lubricating system can be avoided to leak or seepage, dust can be kept off again, ensure sealing effect, improve the working life of seal ring, meet usage requirement.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is generalized section of the present invention.
1. skeletons, 2. rubbery sealed body in figure, 2-1. self-tightening helical spring, 2-2. cuts and has a shave, 2-3. sealing lip.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Lip backbone sealing ring as shown in Figure 1, the rubbery sealed body 2 comprising " L " type metal frame 1 and be coated on skeleton 1 outer side surface, rubbery sealed body 2 has leaf afterbody, leaf tail inner side has spring ditch, spring ditch is built with self-tightening helical spring 2-1, leaf lateral tail has all 2-2 that have a shave, and its rib can avoid the lubricant oil of vehicle lubricating system to leak or seepage, rubbery sealed body 2 is provided with sealing lip 2-3.Rubbery sealed body 2 is provided with anti-slip veins.Wherein, skeleton 1 has ladder position.Skeleton 1 material is the iron-clad through antirust treatment, and the lip backbone sealing ring of this structure, with housing pairing process, can strengthen heat dispersion again while guarantee sealability.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
