Abstract
The invention discloses a frame seal of a dynamic and static ring type for solving the problems of easy contact surface abrasion of a rotary shaft spare part and increased part cost of a traditional frame seal. The frame seal of the dynamic and static ring type comprises a dynamic ring sealing body and a static ring sealing body, wherein a reinforcing frame is arranged on the outer wall of the dynamic ring sealing body, the static ring sealing body is encircled on the inner wall of the dynamic ring sealing body and is provided with a reinforcing frame on the inner wall, the lower part of the dynamic ring sealing body protrudes toward the outer-upper side to form a brim the end of which bends inwards to form a curved surface, a reinforcing tension spring is clamped between the reinforcing frame on the outer wall of the dynamic ring sealing body and the brim curved surface so that the outer wall of the brim curved surface contacts with the reinforcing frame on the inner wall of the static ring sealing body, the bottom of the reinforcing frame on the inner wall of the static ring sealing body protrudes inwards, and the protrusion of the reinforcing frame is provided with a dustproof brim which contacts with the outer side of the bottom of the dynamic ring sealing body. The seal brim of the invention does not contact with the rotary spare part of the equipment to avoid abrading equipment and can save the replacement cost of spare parts and lower the mounting difficulty.
Description
Technical field
The present invention relates to reinforced seal, be specifically related to a kind of frame seal of dynamic and static ring type.
Background technique
Existing reinforced seal is an outside framework oil seal, and being used for needs the parts that lubricate and the parts of exerting oneself to isolate transmission part, is unlikely to allow oil seepage.Existing reinforced seal is an integral type, comprises the annular seal body and the reinforcement spring that are provided with web frame in it, and seal is divided into bottom, waist, lip etc. again according to different parts, and the reinforcement spring is placed in the waist of seal.Web frame plays the effect of reinforcement, and makes the sealing physical efficiency keep shape and tension force.The reinforcement spring is compensation sealing self-tightening power at any time.Under free state, the internal diameter of reinforced seal is littler than the diameter of axle, promptly has certain " magnitude of interference ", when sealing is packed into after sealing seat and axle go up, the contractile force of the pressure of the lip of seal and reinforcement spring produces certain radially tight power to axle, and the reinforcement spring is compensation sealing self-tightening power at any time.Owing between sealing and axle, exist the oil film of seal lip control, this oil film has the fluid lubrication characteristic, and under the effect of surface tension of liquid, the rigidity of oil film makes oil film and air contact jaw form a new lunar surface just, prevent the leakage of working medium, thereby realized the sealing of running shaft.
In use seal lip directly contacts with the rotation axial workpiece, improper in the reinforced seal model that runs into selection, when reason such as not in place perhaps is installed, can cause the contact surface abrasion of rotation axial workpiece, even the reinforced seal that more renews during serious wear, also can't play seal action, can only solve the leakage of oil problem by renewal part, make fittings cost increase.
Summary of the invention
The present invention installs when not in place in order to solve existing reinforced seal, cause the contact surface abrasion of rotation axial workpiece easily, even the reinforced seal that more renews during serious wear, also can't play seal action, can only solve the leakage of oil problem by renewal part, make the problem that fittings cost increases, and a kind of frame seal of dynamic and static ring type is provided.
The present invention is achieved through the following technical solutions:
Frame seal of dynamic and static ring type, comprise that inwall that outer wall is provided with the rotating ring seal of web frame and is located on the rotating ring seal outside is provided with the stationary ring seal of web frame, described rotating ring seal bottom top laterally convexes to form lip, the lip end formation curved surface that curves inwardly, be covered with the reinforcement tension spring between the web frame of rotating ring seal outer wall and the lip curved surface, make the outer wall of lip curved surface contact with the web frame of stationary ring seal inwall, the bottom inwardly protruding of described stationary ring seal inwall web frame, the high spot of web frame is provided with the dust excluder lips that contacts with rotating ring seal bottom outside.In use, rotating ring seal inboard utilizes the magnitude of interference of rotating ring seal, holds a class rotating part and sealing tightly, play sealing and repair the wearing and tearing of rotating component, the effect of manufacturing deficiency, and drive rotating ring seal rotates.Rotating ring seal lip is opened the reinforcement power that strong spring produces by self tension force and reinforcement, compresses the internal surface of stationary ring seal web frame, strikes off the Lubricants that spills in the body, plays seal action.Dust excluder lips on the stationary ring seal is adjacent to the rotating ring seal after being in place, play the effect of sealing and dustproof.
Described lip curved surface is the ptfe plastic circle.
The present invention compared with prior art has the following advantages:
1) the present invention adopts the dynamic and static ring split-type design, and seal lip does not contact with the equipment rotating part, can not cause equipment attrition;
2) rotating ring is inboard makes by certain magnitude of interference for rubber, can be firm hold rotational parts tightly, drive rotating ring and move, also can repair the certain wearing and tearing of rotational parts, so kind is sealed in moving parts have under the situation of certain wearing and tearing, also can use, save the renewal cost of Component;
3) the rotating ring lip adopts ptfe plastic to make, and is combined with each other with the rotating ring rubbery sealed body, has not only saved material, and operation surface friction drag is less, and self lubricity is arranged, and less demanding during installation to the perpendicularity of outside framework oil seal and shaft centre line, reduced installation difficulty;
4) position of the rotational parts installed of rotating ring, because be the rubber surface combination, thus less demanding to the degree of finish of processing, reduced the difficulty of processing of Component.
Description of drawings

Fig. 2 is the partial enlarged drawing of Fig. 1
Among the figure: 1-rotating ring seal, 2-stationary ring seal, 3-reinforcement tension spring, 4-lip, 5-dust excluder lips.
Embodiment
As Fig. 1, shown in Figure 2, frame seal of dynamic and static ring type, comprise that inwall that outer wall is provided with the rotating ring seal 1 of web frame and is located on the rotating ring seal outside is provided with the stationary ring seal 2 of web frame, described rotating ring seal bottom top laterally convexes to form lip 4, the lip 4 ends formation curved surface that curves inwardly, be covered with reinforcement tension spring 3 between the web frame of rotating ring seal 1 outer wall and lip 4 curved surfaces, make the outer wall of lip 4 curved surfaces contact with the web frame of stationary ring seal 2 inwalls, the bottom inwardly protruding of described stationary ring seal 2 inwall web frames, the high spot of web frame is provided with the dust excluder lips 5 that contacts with rotating ring seal bottom outside.
