Definitions
- the invention relates to a segment of a saw chain for high-speed chainsaws for sawing rock, concrete, brick and metal. Such a segment is in the WO 2008/041263 A1 discloses, from which the features of the preamble of claim 1 are known.
- the known chain systems which are suitable for the machining of hard materials such as rock, concrete, brick and metal have chain segments, the members of which are connected transversely to the direction of metal rivets or metal bolts on which the members rotatably support, with each other.
- This construction leads to large chain widths.
- the metal bolts or rivets are also made of relatively soft material, which makes them always worn in the same place, resulting in elongation of the saw chains. The elongation must be compensated by adjusting the saw chain, which leads to failure of the saws and additional repair work with the associated costs.
- From the DE 1 148 481 is a sawing chain for rock known whose segments consist of outer links and inner links, which are connected transversely to the direction of rivets. On the outer and / or inner links grinding materials are arranged, whose distance is only 0.2 to 0.8 mm and which are made wider than the links of the chain. However, the connection of the outer and inner links is made by the conventionally known and wear metal bolt connection.
- the DE 103 11 915 A1 discloses a wear-resistant transport chain, in which outer links, tabs, sleeves and pins ( Fig.1, 2 and 5) surfaces or surface portions of individual parts subject to particular wear are coated with a diamond-like amorphous carbon (DLC) layer. These surfaces may also have metallic particles distributed in the DLC layer and made of tungsten, chromium or titanium.
- This chain design reduces the wear of the chain parts but does not eliminate it. In addition, it is not subject to the high stress of a saw chain for rock.
- a wear-improved timing chain and a method for the production thereof in which elements of the chain, in particular connecting bolt hollow pins, sleeves flaps or rollers in the region of their surface have a coating of a Gleitstoff für or a combination of a hard material and a Gleitstoff für.
- These layers can consist of many different hard metals and their alloys as well as polymers or organic bonded coatings.
- hard-material layers of a nidritic, carbidic and / or carbonitride-type which are applied by all customary dip, spray, powder and PVD / CVD methods, can be applied under the sliding layers.
- the layer thicknesses are between 1 and 15 microns.
- the disclosed chain parts are low-wear but not wear-resistant. In addition, their production is very time consuming only by the required coatings before installation.
- the fasteners made of wear-resistant ceramic material and end roughened peripheral surfaces and the outer members consist of a shrinkable steel and have at least two through holes and at least one in the direction of right-angled tab, the roughened peripheral surfaces with the through holes of two opposing outer members by a shrink-fit and the tabs are positively connected to each other, wherein the end faces of the connecting elements with the outer surfaces of the outer members form a plane.
- the cutting segment are each connected to the upper edges and the tabs of two opposing outer members frictionally with each other.
- a welded connection is preferred for the adhesion of the parts.
- This composite ensures a solid Seat of the cutting segments on the outer links and additionally supports the strength of the composite of the outer links with the connecting elements. Since the cut segments are wider than the segments of the saw chain, only the cut segments are subject to wear but not the chain segments. The saw chain is thus not only wear-free but also maintenance-free.
- the simple design of the individual parts of a segment and their small number in connection with the joining and joining method used is particularly advantageous because it allows an automated and thus easy and fast assembly of the segments and thus time and cost can be produced.
- the wear and maintenance-free structure of the saw chain according to the invention ensures despite these considerable advantages over the prior art, the offer of a low-priced tool that can be disposed of after consumption of the cutting segments.
- two erfindugssecuree segments 1 a saw chain in combination and their individual parts are shown. They consist of two successively arranged in the direction of pairs of outer members 2, which consist for example of a shrinkable heat-treated steel, two in the direction of juxtaposed through holes 2.1 and at its lower edge 2.5 each center in the direction of a right-angled tab 2.2 and in which each have a pair Outer members 2 is arranged opposite one another so that the passage openings 2.1 are opposite transversely to the direction and the tabs facing each other 2.2.
- three inner members 3 are arranged one behind the other in the running direction, which consist for example of alloyed stainless steel X153CrMoV12, 12379, a triangular shape with a top edge 3.2 and two parallel to this passage opening 3.1 two opposite to the cutting direction edges 3.3, the form a corner 3.5 and each have a molded circular segment-shaped recesses 3.4.
- the inner members 3 are arranged with their upper edge 2.4 in the cutting direction between the outer members 2, that always a passage opening 3.1 of an inner member 3 transversely to the direction with two opposing through holes 2.1 of two opposite outer members 2 corresponds.
- the second through opening 3.1 of the same inner member 3 then corresponds to the opposing first through openings 2.1 of the following pair of two opposing outer members 2, etc.
- the connecting elements 4 are preferably made of a wear-resistant sintered zirconium oxide and were produced, for example, as a hollow cylinder.
- the connecting elements 4 have a length which corresponds approximately to the sum of the material thicknesses of the respectively opposite two outer members 2 and the inner member 3 located therebetween.
- the outer diameter of the connecting elements 4 corresponds in the central region approximately to the inner diameter of the passage openings 3.1 of the inner member 3.
- Two end-shaped peripheral surfaces 4.1 are provided for example with a knurling.
- the outer diameter of the peripheral surfaces 4.1 corresponds approximately to the inner diameter of the passage openings 2.1 and the length of the material thickness of the outer members 2 and the end faces 4.2 of the connecting elements 4 are flat.
- a connecting element 4 is rotatably mounted with its central outer diameter in a through hole 3.1 of an inner member 3 and is with his Endally molded peripheral surfaces 4.1 in two adjacent to both outer surfaces of the inner member 3 through holes 2.1 of two opposing outer members 2 by a shrink and press fit anchored so that the outer surfaces 2.3 of the outer members 2 with the end faces 4.2 of the connecting elements 4 form a plane.
- each of the two inner members 3 projecting towards each other ends of the integrally formed on the lower edges 2.5 of the outer members 2 tabs 2.2 are welded together.
- a commercially available cutting segment 5 is, for example, welded on the upper edges 2.4 of two opposing outer members 2 in such a way that it projects beyond the body of each segment 1 on both sides in the running direction.
- the second embodiment according to Fig.3 and Fig.4 shows two segments of a saw chain 1 according to the invention in the composite and their individual parts, wherein the outer members 2 additionally have at its upper edge 2.4 a second formed in the direction of tab 2.2.
- the inner links 3 are executed in a square shape with rounded corners and two arranged in the direction between two corners through holes 3.1 and arranged as a rhombus between the outer members 2.
- a in the cutting direction on the upper edge 2.4 of the outer members 2 protruding corner 3.6 has a rectangular recess 3.7 and serves as Räum leopard and an opposite on the lower edge of the outer members 2 2 protruding corner serves as a transport member of the segment 1.
- FIG. 3 shown composite of two segments 1 shows that only one segment 1 over the two upper edges 2.4 of the outer members 2 with a sectional segment 5 and the two tabs 2.2 at the upper edge 2.4 and the two tabs 2.2 at the lower edge 2.5 of the outer members 2 is welded , A following segment 1 is welded as a dummy segment only over the middle of the upper edge 2.4 and at the lower edge 2.5 of the outer members 2 at right angles to the direction of formed and against each other directed tabs 2.2.
- the connecting elements 4 are made in this example as solid bolts of a ceramic base material, however, have the same outer contour as described in Example 1 and consist for example of a zirconium-reinforced alumina.
Description
Die Erfindung betrifft ein Segment einer Sägekette für hochtourige Motorsägen zum Sägen von Gestein, Beton, Ziegel und Metall. Ein derartiges Segment wird in dem
Die bekannten Kettensysteme, die für die Bearbeitung von harten Materialien wie Gestein, Beton, Ziegel und Metall geeignet sind weisen Kettensegmente auf, deren Glieder quer zur Laufrichtung mit Metallnieten oder Metallbolzen auf denen die Glieder drehbar lagern, miteinander verbunden sind. Diese Bauweise führt zu großen Kettenbreiten. Die Metallbolzen oder -nieten bestehen außerdem aus verhältnismäßig weichem Material, wodurch sie immer an der gleichen Stelle abgenutzt werden, was zu einer Längung der Sägeketten führt. Die Längung muß durch Nachstellung der Sägekette ausgeglichen werden, was zum Ausfall der Sägen und zusätzlichem Reparaturaufwand mit den damit verbundenen Kosten führt.The known chain systems which are suitable for the machining of hard materials such as rock, concrete, brick and metal have chain segments, the members of which are connected transversely to the direction of metal rivets or metal bolts on which the members rotatably support, with each other. This construction leads to large chain widths. The metal bolts or rivets are also made of relatively soft material, which makes them always worn in the same place, resulting in elongation of the saw chains. The elongation must be compensated by adjusting the saw chain, which leads to failure of the saws and additional repair work with the associated costs.
Diesem Problem wurde von einigen Herstellern durch Einsatz abgedichteter Metallbolzen durch O- Ringe und Schmierung der Bolzen entgegengetreten. Derartige Kettenkonstruktionen haben eine zwar eingeschränkte Längung der Ketten zur Folge, nicht aber deren Beseitigung.This problem has been addressed by some manufacturers by using sealed metal bolts through O-rings and bolt lubrication. Such chain constructions have a limited elongation of the chains result, but not their removal.

Schließlich ist aus der
Es war daher Aufgabe der Erfindung ein Segment für eine Sägekette zum Sägen von Gestein, Beton, Ziegel und Metall zu finden, das eine Längung der Kette unterbindet, dessen Bestandteile bis auf das Schnittsegement selbst verschleißfrei und somit wartungsfrei sind, das einen schmalen Bauraum aufweist und durch einen automatisierten Herstellungsprozeß schnell und einfach gefügt werden kann.It was therefore an object of the invention to find a segment for a saw chain for sawing rock, concrete, brick and metal, which prevents elongation of the chain, its components except for the Schnittsegement itself wear-free and thus maintenance-free, which has a narrow space and can be joined quickly and easily by an automated manufacturing process.
Die Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Besonders hervorzuheben ist dabei, daß die Verbindungselemente aus verschleißfestem Keramikmaterial bestehen und endseitig aufgerauhte Umfangsflächen aufweisen und die Außenglieder, gemäß Anspruch 2, aus einem schrumpfungsfähigen Stahl bestehen und mindestens zwei Durchgangsöffnungen sowie mindestens eine in Laufrichtung rechtwinklig angeformte Lasche aufweisen, die aufgerauhten Umfangsflächen mit den Durchgangsöffnungen von zwei gegenüberliegenden Außengliedern durch einen Schrumpf- Preßsitz und die Laschen miteinander kraftschlüssig verbunden sind, wobei die Stirnflächen der Verbindungselemente mit den Außenflächen der Außenglieder eine Ebene bilden.The object is achieved with the features of claim 1. Particularly noteworthy is the fact that the fasteners made of wear-resistant ceramic material and end roughened peripheral surfaces and the outer members, according to
Dieser konstruktive Aufbau gewährleistet einen sehr schmalen Baurraum der Kette. Durch die individuelle Gestaltung der Verbindungselemente, gemäß Anspruch 5, wird darüber hinaus eine optimale Formschlüssigkeit und damit Festigkeit der Verbindung zwischen dem keramischen Verbindungselement und den metallischen Außengliedern geschaffen.This structural design ensures a very narrow space of the chain. Due to the individual design of the connecting elements, according to
Von großem Vorteil sind des weiteren die zwischen zwei gegenüberliegenden Außengliedern, über jeweils eine erste Durchgangsöffnung auf einem ersten Verbindungselement des einen Segmentes und über eine zweite Durchgangsöffnung auf dem zweiten Verbindungselement des folgenden Segmentes um deren Achsen drehbar lagernden Innenglieder, die, gemäß Anspruch 3, aus einem sehr harten Material bestehen, wobei sie die Segmente der Sägekette miteinander verbinden. Durch die Materialwahl der Innenglieder und der darin drehbar gelagerten Verbindungselemente wird die Verschleißlosigkeit beider Teile unterstützt und vor allem die Längung einer Kette, die aus den erfindungegemäßen Segmenten montiert ist, ausgeschlossen.Of great advantage are further between two opposite outer members, each having a first passage opening on a first connecting element of a segment and a second passage opening on the second connecting element of the following segment about the axes rotatably supporting inner members, which, according to
Vorteilhaft ist außerdem, daß das Schnittsegment jeweils mit den Oberkanten und die Laschen zweier gegenüberliegender Außenglieder kraftschlüssig miteinander verbunden sind. Gemäß Anspruch 6 wird für den Kraftschluß der Teile eine Schweißverbindung bevorzugt. Dieser Verbund sichert einen festen Sitz der Schnittsegmente auf den Außengliedern und unterstützt zusätzlich die Festigkeit des Verbundes der Außenglieder mit den Verbindungselementen. Da die Schnittsegmente breiter sind als die Segmente der Sägekette unterliegen nur die Schnittsegmente einem Verschleiß nicht aber die Kettensegmente. Die Sägekette ist dadurch nicht nur verschleißfrei sondern auch wartungsfrei.It is also advantageous that the cutting segment are each connected to the upper edges and the tabs of two opposing outer members frictionally with each other. According to claim 6, a welded connection is preferred for the adhesion of the parts. This composite ensures a solid Seat of the cutting segments on the outer links and additionally supports the strength of the composite of the outer links with the connecting elements. Since the cut segments are wider than the segments of the saw chain, only the cut segments are subject to wear but not the chain segments. The saw chain is thus not only wear-free but also maintenance-free.
Hervorzuheben ist auch eine zweite Variante der erfindungsgemäßen Segmente bei der die Innenglieder, gemäß Anspruch 4, eine Bauform mit angeformten Räumzähnen aufweisen und die Außenglieder an ihrer Ober- und Unterkante mit abgewinkelten Laschen ausgestattet sind. Diese Variante gestattet, daß nur jedes zweite Segment mit einem Schnittsegment ausgestattet werden muß und das die Außenglieder, insbesondere diejenigen die als Blindglied eingebaut sind, über die angeformten Laschen an Ihrer Ober- und Unterkante verschweißt sind und dem Segmentverbund eine zusätzliche Stabilität verleihen. Aufgrund der Einsparung von Schnittsegmenten ist diese Variante hinsichtlich des Materialaufwandes etwas wirtschaftlicher.Also to emphasize is a second variant of the segments according to the invention in which the inner members, according to claim 4, have a design with integrally formed Räumzähnen and the outer members are equipped at their upper and lower edges with angled tabs. This variant allows that only every other segment must be equipped with a cutting segment and the outer members, in particular those which are installed as a blind member, are welded over the molded tabs at their top and bottom edges and give the segment composite additional stability. Due to the saving of cutting segments, this variant is somewhat more economical in terms of material costs.
Schließlich ist die einfache Bauform der Einzelteile eines Segmentes und deren geringe Anzahl in Verbindung mit den eingesetzten Füge- und Verbindungsverfahren besonders vorteilhaft, da sie einen automatisierten und damit einfachen und schnellen Zusammenbau der Segmente gestattet und somit zeit- und kostengünstig herstellbar ist. Das verschleiß- und wartungsfreie Gefüge der erfindungsgemäßen Sägekette sichert trotz dieser erheblichen Vorzüge gegenüber dem Stand der Technik das Angebot eines preisgünstigen Werkzeugs, daß nach Verbrauch der Schnittsegmente entsorgt werden kann.Finally, the simple design of the individual parts of a segment and their small number in connection with the joining and joining method used is particularly advantageous because it allows an automated and thus easy and fast assembly of the segments and thus time and cost can be produced. The wear and maintenance-free structure of the saw chain according to the invention ensures despite these considerable advantages over the prior art, the offer of a low-priced tool that can be disposed of after consumption of the cutting segments.
