Abstract
The utility model relates to a composite oil seal for a clutch of a laundry machine. An internal ring and an external ring of the utility model which can play sealing action are not easy to deform; concentricity of the internal ring and the external ring can be ensured, and sealing properties of the internal ring and the external ring and a dehydration shaft and a water containing barrel are higher. The utility model comprises a skeleton body which is distributed with rubber bodies on a peripheral portion. The utility model is characterized in that the internal ring surface and the external ring surface of the rubber bodies are respectively used as a sealing surface, and the sealing surfaces are respectively provided with a cutting edge which can play sealing action.
Description
(1) technical field
The utility model relates to the use in washing machine seal, is specially the clutch coupling of washing machine combination oil seal.
(2) background technology
The load of laundry machine dehydration axle outer cover connects dehydration barrel, and the outside of described dehydration barrel is a steel ladle.In order to prevent that the washings in the dehydration barrel from oozing out between dehydrating shaft and steel ladle, therefore, between dehydrating shaft and dehydration barrel, steel ladle, big sealing, little sealing are set.And big sealing is respectively two independent sectors with little sealing, to seal greatly during installation and little sealing between seal of chimeric formation, its side face cooperates with the inner peripheral surface of steel ladle, inner ring hugs dehydrating shaft, make the complementary sealing function of inside and outside sealing surface, can prevent fully that like this washings from flowing out from the bottom of washing machine.The shortcoming of this seal is exactly: chimeric between two seals, its concentricity is difficult to guarantee that after integral body of both chimeric formation, inner ring and outer ring are yielding, thereby can have influence on the sealing of oil sealing and dehydrating shaft, steel ladle.
(3) summary of the invention
At the sealing of existing clutch coupling of washing machine, by chimeric between two seals, make the complementary sealing function of inside and outside sealing surface, but because the concentricity of two seals is difficult to guarantee, after integral body of both chimeric formation, inner ring and outer ring are yielding, thereby can have influence on the shortcoming of the sealing of oil sealing and dehydrating shaft, steel ladle, the utility model provides a kind of clutch coupling of washing machine combination oil seal, inner ring that it seals and outer ring are not yielding, the concentricity of inner ring and outer ring can guarantee, the sealing of itself and dehydrating shaft, steel ladle is higher.
Its technical scheme is such: it comprises skeleton body, and the perimembranous distribution rubber bodies of described skeleton body is characterized in that: the inner peripheral surface of described rubber bodies and surface, outer ring are respectively sealing surface.
It is further characterized in that: described sealing surface is respectively arranged with the cutting edge that seals.
The utility model adopts after the said structure, because sealing function all can be played in inner ring and outer ring, as long as just can solve sealing problem between itself and dehydrating shaft, the steel ladle with a seal, so also just do not exist owing to the chimeric oil sealing that causes is out of shape, sealing can be guaranteed.
(4) description of drawings
Fig. 1 be the utility model in washing machine with the structural relation schematic diagram of critical piece on every side;
Fig. 2 is a cutaway view of the present utility model.
(5) specific embodiment
See Fig. 2, the utility model comprises skeleton body 8, the perimembranous distribution rubber bodies 5 of skeleton body 8, and the inner peripheral surface of rubber bodies 5 and surface, outer ring are respectively sealing surface.Sealing surface is respectively arranged with the cutting edge 9,10 that seals.Among Fig. 1,1 is the installation site of agitation wheel for washing machine, and 2 is wash shaft, and 3 is dehydrating shaft, and 4 is steel ladle, and 6 is the seal between oil sealing and the steel ladle, and 7 is the installation site of dehydration barrel.
Claims (2)
1, clutch coupling of washing machine combination oil seal, it comprises skeleton body, the perimembranous distribution rubber bodies of described skeleton body is characterized in that: the inner peripheral surface of described rubber bodies and surface, outer ring are respectively sealing surface.
2, according to the described combination oil seal of claim 1, it is characterized in that: described sealing surface is respectively arranged with the cutting edge that seals.
