Abstract
The utility model discloses a novel skeleton inside seal circle has: the cross -section is the quoit skeleton of " L " shape, be the annular rubber body, it is the rubber layer of a body structure to personally experience sth. Part of the body with rubber, and wrap up on the quoit skeleton on the rubber layer, the rubber body still wraps up: locate the internal side of rubber and follow the convex first seal lip of its axial, it along the convex second seal lip of its axial, locates the internal side of rubber and along its radial convex third seal lip, locates the external side of rubber and follow its radial convex fourth seal lip to locate the internal side of rubber. The utility model discloses present inside seal circle, a newly -increased fourth lip, make the product be used in' L' appears has fine sealed effect on the fitting piece rather than interference fit outside the quoit, it is better to seal up the effect.
Description
Technical field
The utility model relates to a kind of Novel framework inner seal ring.
Background technique
The shape of black box, component, the effect of material to sealing effect and black box plays an important role, the seal ring of common black box has V-shaped seal ring, U-shaped circle, O RunddichtringO, square RunddichtringO, y-type seal ring, hole YX RunddichtringO, YX nibs back-up ring, axle YX RunddichtringO, axle YX type back-up ring, O type rubber seal, O-ring seals back-up ring, the exoskeletal dust ring of J type 12 kinds, this 12 inner seal ring is used in different occasions according to the shape of oneself and structure, respectively there are the pluses and minuses of oneself, but in life, in the sealing of different occasion different field, still there is numerous sealing demands, the better seal ring of sealing effect of development different structure and shape meets more sealing demands, realize the key of better sealing effect.
In widely used industrial original paper bearing or hub, the sealing effect of each parts seems particularly important, because it is larger that bearing or hub damage maintenance trouble, maintenance cost is higher, and use the equipment of industrial original paper bearing or hub usually can run in rugged environment or frequent running process, dust or mud etc. easily enter in bearing or hub, be difficult to cleaning on the one hand, easily cause the infringement of bearing or wheel hub on the other hand, the inconvenience brought extremely is used to vehicle, meanwhile, adding users uses the cost of vehicle; Further, if sealing effect is bad, then the grease of bearing or hub may be caused to leak outside, have a strong impact on its performance.
Model utility content
The purpose of this utility model is exactly that the grease in product oozes out the problem outside product, provides a kind of Novel framework inner seal ring in order to solve dust or mud enters in product.
To achieve these goals, the utility model adopts following technological scheme:
A kind of Novel framework inner seal ring, comprise eyelet skeleton and rubber body, it is characterized in that: described eyelet skeleton cross section is vertically L-shaped, described rubber body in the form of a ring, be pasted onto eyelet skeletal internal and along the axis of eyelet skeleton and the radial outside being wrapped in eyelet skeleton, described rubber body is also provided with the first sealing lip being positioned at and axially protruding inside rubber body and along eyelet skeleton, be positioned at the second sealing lip axially protruded inside rubber body and along eyelet skeleton, be positioned at the 3rd sealing lip protruded inside rubber body and along eyelet skeleton radial direction, be positioned at the 4th sealing lip protruded outside rubber body and along eyelet skeleton radial direction.
Described first lip and the second lip are used for the interference fit with dust cover or magnetic gasket lower surface, can interference 0.3-0.4mm; Described 3rd lip is used for the Extrude Face interference fit with dust cover or magnetic gasket, can interference 0.1-0.15mm; Described 4th lip is used for coordinating with the outer ring of fixed product or flange plate.
The sagittal plane of described eyelet bone is axially upwards locked little close to upper surface gradually, reduction scope 0-0.05mm, and the rubber body of wrapping up changes thereupon; To be positioned at outside rubber body and along the protruding 0.15mm of the 4th sealing lip distance eyelet skeleton radially-outer surface that eyelet skeleton radial direction is protruded, to be wrapped in the rubber body upper surface 0.95mm of eyelet skeleton from the axis along eyelet skeleton.
The beneficial effects of the utility model are: the first lip and the second lip coordinate with the lower surface interference 0.3-0.4mm of dust cover or magnetic gasket, 3rd lip coordinates with the Extrude Face interference 0.1-0.15mm of dust cover or magnetic gasket, prevent grease in product from spilling, cause steel ball and raceway unlubricated, friction factor strengthens, cause raceway to wear and tear and make product produce abnormal sound and damage, improve the life-span of bearing or hub, 4th lip coordinates with the outer ring or flange plate that need fixed product and prevents extraneous dust or mud from entering in the bearing of High Rotation Speed, steel ball and raceway is caused to rub, cause raceway to wear and tear and make product produce abnormal sound and damage, improve the life-span of bearing or hub.The utility model is existing product comparatively, and newly-increased four lips, product is acted on outside " L " shape eyelet with on the counterpart of its interference fit good seal action, and sealing effect is better.

Embodiment
The utility model is set forth further below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of Novel framework oil sealing, coated metal ring framework 5 and rubber body 6, described eyelet skeleton 5 cross section is vertically L-shaped, described rubber body 6 in the form of a ring, be pasted onto eyelet skeleton 5 inner and along the axis of eyelet skeleton and the radial outside being wrapped in eyelet skeleton, described rubber body 6 is also provided with the first sealing lip 1 being positioned at and axially protruding inside rubber body and along eyelet skeleton, be positioned at the second sealing lip 2 axially protruded inside rubber body and along eyelet skeleton, be positioned at the 3rd sealing lip 3 protruded inside rubber body and along eyelet skeleton radial direction, be positioned at the 4th sealing lip 4 protruded outside rubber body and along eyelet skeleton radial direction.
Described first lip 1 and the second lip 2, can interference 0.3-0.4mm for the interference fit with dust cover or magnetic gasket lower surface; Described 3rd lip 3, can interference 0.1-0.15mm for the Extrude Face interference fit with dust cover or magnetic gasket; Described 4th lip 4 is for coordinating with the outer ring or flange plate of fixed product.
The sagittal plane of described eyelet skeleton 5 is axially upwards locked little close to upper surface gradually, reduction scope 0-0.05mm, and the rubber body 6 of wrapping up changes thereupon; To be positioned at outside rubber body and the 4th sealing lip 4 protruded along eyelet skeleton radial direction apart from the protruding 0.15mm of eyelet skeleton radially-outer surface, be wrapped in the rubber body upper surface 0.95mm of eyelet skeleton from the axis along eyelet skeleton.
When this product is arranged on bearing or hub with the dust cover coordinated or magnetic circle, naked leakage outside, be illustrated in figure 2 schematic diagram when the utility model is combined with other water-tight equipment, the environment contacted with it is more severe, the foreign matter such as dust or mud is had to impact on product, as 2 dust mud arrow moving direction in figure, at this moment just need reasonable sealing configuration and performance.Newly-increased 4th lip can effectively avoid from L shape eyelet and with it interference 0.10-0.20mm cooperation ironware enter the danger of foreign matter.
