Definitions
- the invention relates to a seal, a method for the production thereof and a seal arrangement comprising the seal.
- Seals are well known and reach, for example, for sealing rotating or translationally movable machine elements
- the machine elements that are sealed may be, for example, shafts, rods, spindles or roller bearings. Sealed are often liquid or pasty media to the environment, or, impurities from the environment of the machine elements, such as
- Example Dirt, dust, salt and / or moisture are kept away from the inside of the machine elements where the seals are located by seals.
- the seals can be designed as sealing rings and, depending on
- seals that seal a diameter of more than 400 mm, have a complex structure and are therefore complicated and expensive to manufacture.
- Most such seals consist of several
- CONFIRMATION COPY Parts such as a support body made of a metallic material, which is connected to a sealing element made of elastomeric material.
- the invention has for its object to develop a seal of the type mentioned in such a way that it has a simple and teilarmen structure, is inexpensive to produce and can be easily assembled, especially if the seal very large diameter, for example, of several Meters.
- This object is achieved by a seal, a method for their preparation and a seal assembly having the features of the independent claims.
- a seal comprising a substantially H-shaped sealing profile.
- An H-shaped sealing profile is easy and inexpensive to produce and easy to install.
- the substantially H-shaped sealing profile comprises, viewed in cross section, two spaced apart longitudinal webs, which are interconnected by a transverse web.
- the sealing profile is formed symmetrically to an imaginary plane, which, viewed in cross section, is arranged centrally of the transverse web.
- Such a symmetrical design is particularly easy to assemble, because each of the two longitudinal webs has the same performance characteristics and the direction in which the sealing profile is installed, for the function of the seal therefore does not matter. The risk of assembly errors is thereby reduced to a minimum.
- the crossbar is designed as a hinge, around which the longitudinal webs are pivotable relative to each other like a clothespin.
- the longitudinal webs, each starting from the crosspiece, on the one hand have a clamp arm and on the other hand a sealing lip.
- Machine element in which the seal is fixed compared to another machine element.
- the ratio of the length of the sealing lips to the length of the corresponding clamping arms of the respective longitudinal webs is preferably at least two starting from the transverse web. It is advantageous that the clamping arms, based on the corresponding sealing lips of the longitudinal webs, compact and thus dimensionally stable. Through this dimensionally stable design of the clamp arms, the seal can be very precisely with a
- the sealing lips have a greater flexibility, in order to be able to invest better on the surface of the machine element to be sealed. Due to the elastic compliance of the sealing lips can
- the clip arms are formed latching nose-shaped.
- the clamp arms can be an undercut in the installation groove of the
- Machine element on which the seal is fixed engage behind to produce a positive connection.
- the locking lugs of the clamp arms also act as a static seal for sealing the installation groove. Due to the latch-nose-shaped, free end of the staple arms, the seal is snapped into the installation groove.
- the ratio of the length of the sealing lips to the articulated width of the transverse web is preferably 0.75 to 1.5.
- Lubricant in the lubricant reservoir the abrasive wear of the dynamically stressed sealing lips is reduced to a minimum and also formed a barrier between the two sealing lips, the
- the mutually facing flanks and / or the mutually remote flanks of the sealing lips may have a surface profiling.
- the surface profiling may for example be formed by a slight grooving, which forms additional micro-lubricant depots.
- the lubricant contained in the micro-lubrication depots reduces the friction between the sealing lips and the relatively movable to be sealed
- the seal is preferably formed of the same material, consists of a material having elastomeric properties and has a hardness Shore A of 70 to 95.
- Such a seal has a satisfactorily large dimensional stability even without separately produced support body.
- the material may be formed by a polyurethane. Such materials have a comparatively low coefficient of friction. During the intended use of the seal thereby becomes Heat development in the region of the sealing points between the sealing lips and the machine element to be sealed reduced.
- a further reduction of the friction torque and an improvement of the run-flat and dry running properties can be achieved that the material contains friction-reducing fillers.
- friction reducing fillers may be formed by PTFE particles, for example.
- the seal may be formed, for example, as a sealing ring.
- a sealing ring can, for example, seal a shaft with respect to a housing, wherein the shaft penetrates the housing.
- the invention relates to a method for producing a seal, as described above, in which in a first procedural document, an endless band-shaped sealing profile is extruded and cut to length in a second method step, wherein the cut sealing profile in a third
- Process step is annular deformed and wherein the two free ends of the sealing ring formed to the sealing profile in a fourth
- Process step selected the extrusion process.
- the sealing profile can be formed into a sealing ring with a diameter> 400 mm.
- Seals made by other manufacturing processes may consist of several parts and include support body and / or ring coil spring, the joining of these parts is complicated each other.
- the seal according to the invention in contrast, does without additional elements, such as, for example, supporting bodies and / or annular helical spring, and is designed as a whole in one piece and of the same material.
- a sealing ring with a large diameter of, for example, about 4m can be saved by the inventive method and the inventive seal large amounts of steel for unnecessary support body and components and thus in the case of rotating seals the
- Effectiveness of a plant can be improved. Furthermore, the efficiency of the tools for producing the seal can be increased by lower masses to be moved.
- the two free ends can be welded together in the fourth step.
- the mirror welding is used for the welding of the free ends together.
- Mirror welding is also called
- Heated butt welding refers and serves to connect plastic components together. By supplying heat via a heating element, the components to be joined together are brought into a thermoplastic state in the region of their joints and then connected together under pressure.
- sealing rings With an almost unlimited size can be produced
- the welding method described has the advantage that can thus produce joints, with a homogeneous material at the joint, ie at the free ends. Incorporated material by joining, do not have the joints. This allows high durability and resistance to temperature variations and chemical influences at the seam between the two free ends at the level of the original material.
- the third and the fourth method step can, if necessary, be carried out "on site", for example, on the construction site, which has the advantage that the initially endless, band-shaped
- the invention relates to a seal assembly, comprising a seal, as described above and at least two machine elements, wherein the seal is arranged with their clip arms each positively in a Einbaunut of a machine element and the Einbaunut with its clamping arms substantially static sealing touches and the other machine element touched with the sealing lips dynamic sealing.
- the Machine elements can be formed by bearing shells of a slewing bearing. Such large-diameter bearings can be used in wind turbines, the diameter used for seals may well be about 4m and more.
- the one machine element may be formed by a housing with a bore, the other machine element by a shaft, which from the
- Housing is enclosed with a radial distance, wherein in the gap formed by the gap, the seal is arranged, which surrounds the shaft with its sealing lips dynamic sealing.
