Definitions
- the invention relates to a saw chain with chain links, such as saw members and links, wherein the chain links have rivet openings in which bolts are arranged, which form articulated connections between the chain links, and wherein at least one sealing means is provided between the facing surfaces of the chain links around each rivet opening , Furthermore, the invention relates to a method for producing a saw chain.
- Chain links with sealing means are known around each rivet opening, wherein a sealing ring inserted in a bead is provided as sealing means.
- the disadvantage of this is that there are two sealing surfaces between the sealing ring and the two chain links. This can lead to Abuitee ⁇ or impurities on both sealing surfaces.
- the assembly of the saw chain by the respective insertion of the sealing rings between the chain links is very complex.
- the object of the invention is thus to provide a saw chain and a method for their production, which eliminates the above-mentioned disadvantages.
- sealing means is formed directly on a chain link and thus only one sealing surface is formed to the opposite chain link.
- the height and width of the resulting sealing bead can be varied as required by changing the pressure, the amount and the composition of the sealing material.
- a feature of the invention is that at least the chain link on which the sealant is formed has an annular bead around the rivet opening for receiving the sealant.
- the sealing means may be arranged as a star-shaped ring with at least three spaced from the rivet opening teeth around the rivet opening around.
- This embodiment has the particular advantage that collecting dirt between the teeth of the star is conveyed by the relative movement of the two chain links to each other via the star tips of the sealant to the outside and thus can not penetrate to the rivet opening.
- the sealing means can be applied flat over the entire surface of the chain link.
- the chain link may have at least three bulges in the form of nubs around the rivet opening on the surface facing the opposite chain link. These nubs can be formed for example by embossing the chain link. These nubs ensure a certain minimum distance between the chain links, wherein the relative movement of the chain links to each other by sliding over the Noppenköpfe takes place, similar to a ball bearing.
- the sealant is as described above 1 either around the rivet in a bead or flat over the entire chain link, it comes due to the existing knobs to a lower wear of the sealant.
- sealing means may be arranged, for example, in concentric rings around the rivet opening.
- the object of the invention is achieved by a method for producing a sawing chain, which is characterized in that the sealing means is applied by a printing method, preferably by a screen printing method on the chain link and thus formed on this.
- the screen printing technology makes it possible to print in a single pass between 100 and more than 1000 links in a few seconds.
- the expense for the classic screen printing technique itself is low, with a screen with the desired pattern as openings and the application technique.
- a distance is necessary, the so-called "jump.”
- the screen should have a distance of 2 - 3 millimeters from the print material after printing.
- Another variant of the screen printing works from the outset with a distance of about one millimeter, because the sealant must have a minimum thickness and the pressure is at a distance.
- the uniform application is more difficult to design because the sieve no longer works as a flow limiter.
- sealants there are a wide variety of materials which can be used as sealants:
- This template should have the following required properties:
- holding device for the chain links e.g. Magnet, negative pressure, clamp
- Non-adherent covering of the printed material to achieve a uniform height of the seals Another approach would be to use a rotating screen that moves with the material to be printed and applies the mass during the movement.
- Another alternative is a form of writing the gasket onto the chain link using an ink jet printer or comparable printhead.
- a further feature of a method according to the invention for producing a saw chain is that the sealing means is present as a two-component system and is formed on the chain link by bringing the two components together at the corresponding position on the chain link.
- the sealant is positioned on the chain link and molded thereon by vulcanization.
- the shaping of the sealant on the chain link can also be carried out by the action of temperature, for example heat or cold, or radiation, for example UV radiation.
- FIG. 1 shows a perspective view of a chain link of a saw chain according to the invention.
- Fig. 2 shows a longitudinal section through two adjacent chain links of a saw chain according to the invention.
- 3 shows a longitudinal section through an alternative embodiment of two chain links of a ner saw chain according to the invention.
- 4 shows a plan view of a chain link of a further embodiment of a saw chain according to the invention.
- the chain link 1 shown in FIG. 1 has rivet openings 2, via which the other chain links are articulated by means of bolts 3.
- an annular seal 4 which is formed according to the invention on the chain link 1.
- Chain links for a saw chain have a special distribution of forces.
- the bolt in the rivet hole absorbs the tensile loads that are transmitted from the chain links to the bolt. This results in a considerable bending moment, which is absorbed by a short, massive, bolt-like construction.
- Both chain links have rivet openings which underlie even very high tensile stresses.
- a bead 5 is provided around the rivet opening, in which the sealant 4 is received.
- the sealant By applying the sealant a lower overall height of the sealing ring of 0.4 mm should be achieved.
- the supernatant of the sealant will be about 0.1 - 0.2 mm.
- the seal must fit under full load into the bead without destroying the material. This results in a depth of the bead of 0.3 - 0.4 mm. Greater depth provides more room for compression and allows for longer seal life.
- Fig. 3 an embodiment is shown, in which the sealing means 4 is applied over the entire surface of the chain link 1.
- embossed knobs 6 are also arranged.
- the sealant 4 in the edge region of the chain link 1 quickly wears off, as a result of which comes to a contact between the studs 6 and the opposite chain link 1.
- FIG. 4 shows a further embodiment of a chain link 1 with a sealing means 4 around the rivet opening 2, in which case the sealing means 4 is arranged as a star-shaped ring.
- the sealing means 4 is arranged as a star-shaped ring.
