Abstract
The utility model relates to the technical field of sealing, in particular to a lip-shaped sealing ring of a rotary shaft. The lip-shaped sealing ring of the rotary shaft comprises a skeleton and a rubber sealing body wrapped on the inner side of the skeleton, wherein the skeleton is an L-shaped metal skeleton; the rubber sealing body is provided with a blade tail part; a spring groove is formed on the inner side of the blade tail part; a spring body is arranged in the spring groove; and a cutting surface is formed on the other side of the blade tail part. The skeleton of the lip-shaped sealing ring of the rotary shaft is designed on the basis of pure rubber so as to greatly facilitate the assembling of the sealing ring, ensure the assembling and positioning of the seal, avoid the escape or leakage of lubricating oil of an automobile lubricating system, guarantee the sealing effect, prolong the service life of the sealing ring, and meet the using requirement.
Description
Technical field
The utility model relates to technical field of sealing technology, especially a kind of rotary shaft lip seal.
Background technique
Seal ring is installed in vehicle lubricating system, traditional seal ring is generally single rubber material or other macromolecular materials, when the seal ring of this structure is the housing pairing, its sealing effect is difficult for guaranteeing, its material also easily follows the string because of aging distortion, thereby working life is shorter, needs frequent, affects the operational efficiency of equipment.In addition, because sealing effect is undesirable, the lubricant medium of lubrication system is leaked or seepage, can not satisfy user demand, serious entail dangers to personal safety.
The model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of easy for installation, the rotary shaft lip seal of good sealing effect.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of rotary shaft lip seal, comprise skeleton and the rubbery sealed body that is overlying on the skeleton inner side surface, described skeleton is " L " type metal frame, described rubbery sealed body has the leaf afterbody, the leaf afterbody has the spring ditch to the inside, in the spring ditch spring body is housed, described leaf afterbody opposite side has all and has a shave.
Further, be provided with dust excluder lips on the described rubbery sealed body, can play effective dust-proof effect.
Further, in order to improve its sealing, be provided with ripple at described rubbery sealed body outer side surface.
The beneficial effects of the utility model are, rotary shaft lip seal of the present utility model is design framework on the basis of gum, greatly facilitate the installation of seal ring, guaranteed better the assembling and positioning of sealing, avoid the lubricant oil of vehicle lubricating system to leak or seepage, guarantee sealing effect, in the working life of having improved seal ring, satisfy usage requirement.
