Abstract
The invention discloses a split embedding engagement molded seal ring, which comprises a rubber plastic outer ring and a rubber seal inner ring, wherein the hole wall of an inner ring hole of the rubber plastic outer ring is provided with N circumferential engagement grooves; the outer circular side face of the rubber seal inner ring is uniformly provided with N engagement bumps; the sizes and the shapes of the engagement bumps correspond to those of the circumferential engagement grooves; and the rubber seal inner ring is engaged in the circumferential engagement grooves of the rubber plastic outer ring through the engagement bumps by means of die pressing. In the split embedding engagement molded seal ring, the rubber plastic outer ring with high rigidity is arranged, so that necessary elastic interference fit can be kept with a shell, and distortion is not produced during mounting; the rubber seal inner ring can also tightly wrap a shaft to be sealed; since coefficients of deformation of the rubber plastic outer ring and the rubber seal inner ring are close to each other, the rubber plastic outer ring and the rubber seal inner ring can synchronously expand with heat and contract with cold when the working temperature of the seal ring is raised; and thus, degumming and stripping phenomenon produced due to different shrinkage rates is avoided, and the service life of a product is prolonged.
Description
Technical field:
The present invention relates to a kind of split inlays and is bited into RunddichtringO.
Background technique:
Existing rubber seal adopts the gum compression molding usually; This type rubber seal is easy to produce distortion because intensity is hanged down when assembling; In order to overcome the defective of rubber seal insufficient rigidity easy deformation; Common way is in rubber seal, to set up metal frame, to improve the rigidity of rubber seal external diameter.But because metal frame rigidity is too big, elasticity is very low, if the rubber layer thickness of parcel is too small, rubber layer is torn inefficacy easily in assembly process.Because the deformation coefficient of metal frame is different with rubber, when the operating temperature of seal ring raise, metal frame was different with the amount of deformation of rubber layer, is easy to produce degumming phenomenon between the two on the other hand, and the working life of product is not long.
Summary of the invention:
The purpose of this invention is to provide a kind of split and inlay and be bited into RunddichtringO, it had both had the advantage of backbone sealing ring, had overcome the shortcoming of backbone sealing ring again, and simple in structure, rubber consumption is few, and good seal performance is with low cost.
The technological scheme that the present invention takes is following:
A kind of split is inlayed and is bited into RunddichtringO; It is characterized in that: comprise rubber and plastic outer ring and rubber seal inner ring; On the inner ring hole wall of rubber and plastic outer ring, be provided with equably N circumferential snap groove and N circumferentially in convex body, N >=1, the circumferential snap groove is made up of notch and vallecular cavity; The size of notch is less than the overall dimensions of vallecular cavity, and the size of notch is more than or equal to 5 millimeters; Convex body outside N the interlock is evenly arranged on the cylindrical side of rubber seal inner ring; Size, the shape of the outer convex body of interlock are all corresponding with the circumferential snap groove; The rubber seal inner ring is embedded in the circumferential snap groove of rubber and plastic outer ring through the outer convex body of interlock, and rubber and plastic outer ring and rubber seal inner ring are fixedly connected and are integral through inlaying occlusion structure.
Further, inlay in split and to be bited in the RunddichtringO, circumferentially in the convex body lateral cross section be shaped as rectangle or trapezoidal.
Further, inlay in split and to be bited in the RunddichtringO, in circumferentially, be provided with radially occlusal crib on the convex body.
Further, inlay in split and to be bited in the RunddichtringO, be provided with the glue adhesive layer at the gummed place of rubber and plastic outer ring and rubber seal inner ring.
Further, inlay in split and to be bited in the RunddichtringO, being shaped as of the circumferential snap groove on the rubber and plastic outer ring is fan-shaped with one heart.
Further, inlay in split and to be bited in the RunddichtringO, the circumferential snap groove on the hole wall of rubber and plastic outer ring inner ring hole be shaped as T shape.
Because the existing hardness of rubber and plastic is flexible again; Go out the rubber and plastic outer ring with shell with the mold pressing of rubber and plastic elder generation, it is the static seal part of seal ring, on the inner ring hole wall of rubber and plastic outer ring, be provided with equably N circumferential snap groove and N individual circumferential in convex body; The circumferential snap groove distributes with circumferentially interior convex body alternate intervals; Occlusal crib is made up of notch and vallecular cavity, and the size of notch is less than the overall dimensions of vallecular cavity, and the size of notch is more than or equal to 5 millimeters; Form the rubber seal inner ring so that to be the moulding skeleton carry out mold pressing with the rubber of excellent elasticity in the rubber and plastic outer ring then; On rubber seal inner ring cylindrical side, suppress convex body outside the interlock; Make the rubber seal inner ring inlay snap-fit with the rubber and plastic outer ring; Be that the outer convex body of interlock on the rubber seal inner ring is embedded in the circumferential snap groove on the rubber and plastic outer ring, also can the rubber seal inner ring be installed in the endoporus of rubber and plastic outer ring, make both formation structure that is fixed as one through moulded glued mode.If in circumferentially, set up radially occlusal crib on the top and bottom of convex body, both realized circumferential snap between rubber and plastic outer ring and the rubber seal inner ring, realize radially interlock again, connect more reliably, can bear bigger shearing force.The rubber and plastic outer ring that is bited into the existing higher stiffness of RunddichtringO is inlayed in this split; Flexible again fabulous rubber seal inner ring; The rubber and plastic outer ring of high rigidity can keep necessary elasticity interference fit with housing; Can not produce torsional deformation during installation, the rubber seal inner ring can wrap axle to be sealed by hard-pressed bale, if it is higher on the hole wall of rubber and plastic outer ring inner ring hole and in the vallecular cavity, to coat the adhesive glue join strength.Because rubber and plastic outer ring and rubber seal inner ring deformation coefficient are approaching, when the operating temperature of seal ring raises, can expand with heat and contract with cold synchronously between the two, therefore can not occur refuting from phenomenon because of different the coming unstuck of producing of shrinkage, be able to the working life of product prolong.
