Definitions
- the invention relates to the technical field of chains and, more particularly, to the field of sawing chains.
- These chains are generally mounted on sawing machines such as chainsaws, shearers or the like.
- sawing machines consist of a motor, a blade - or guide - and a saw chain consisting of several links. At least a portion of these links support and hold a tool - also called "gouge" - square, half-round, or other shape and has a sharp edge.
- Some of these sawnwood chains have unique links of identical shape. Others have inner links alternating with outer links.
- the sawing tools can then be supported and maintained by all or part of the inner and outer links. In particular, and more frequently, these tools are supported and maintained by all the external links or by all the inner links.
- the choice of this configuration largely depends on the properties of the material to be cut, the cutting speed, etc.
- Such saw chains are, for example, used in underground quarries to cut blocks of rocks.
- the invention relates to a modular chain comprising outer links and inner links, each outer link being intended to be associated directly with an upstream inner link and a downstream inner link and indirectly with other external links.
- the outer link comprises: a first outer part extending substantially in a longitudinal direction, the first part being provided with an upstream bore, and a downstream bore substantially spaced from the upstream bore in the longitudinal direction; a second outer piece extending substantially in a longitudinal direction, the second piece having an upstream bore, and a downstream bore substantially spaced from the upstream bore in the longitudinal direction; an upstream pin having a first end portion adapted to be inserted into the upstream bore of the first outer member; and a second end portion adapted to be inserted into the upstream bore of the second outer piece; the upstream pin having at least one central shoulder positioned between the first end portion and the second end portion and having a diameter greater than the diameters of the upstream bore of the first piece and the upstream bore of the second piece; and a downstream pin having a first end portion adapted to be inserted
- the invention further relates to a method of mounting a modular chain according to the invention.
- each pin has two end portions of diameter D t0U r slightly greater than the diameter D ext of the bores of the outer parts so that these pins can be stamped into said bores of the first and second outer parts.
- This type of saw chain has several disadvantages.
- the stamping of the pins in the bores is a complex step and difficult to reverse, which makes it difficult to add or remove links when, for example, a sawing tool breaks and the corresponding link must be replaced. .
- Each link has a first end portion formed by two receiving branches, positioned vis-à-vis and defining an internal space.
- each branch is provided with a bore of diameter D rec , the bores of these two branches being also positioned vis-a-vis.
- the links also have a second end portion formed by an insertion arm having a bore of diameter D ins .
- a first link with a second identical link by inserting the insertion branch of the first link in the internal space defined by the two receiving branches of the second link and then introducing, by stamping , a trunnion of diameter D t0U r in the bores of the two receiving branches of the second link and in the bore the insertion arm of the first link.
- the diameter D t0U r of the trunnion is slightly greater than the diameter D rec of the bores of the receiving branches of the second link but less than the diameter D ins of the bore of the insertion arm of the first link.
- the journal is thus maintained, by stamping, in the bores of the receiving branches of the second link and the insertion arm of the first link can move in rotation around the journal.
- the diameter D t0U r of the trunnion is slightly greater than the diameter D ins of the bore of the insertion branch of the first link but less than the diameter D rec of the bores of the receiving branches of the second link.
- the journal is thus maintained, by stamping, in the bore of the insertion branch of the first link and the receiving branches of the second link can move in rotation around the pin.
- This type of sawing chain has disadvantages similar to those previously mentioned.
- the mechanical stresses generated on the links of the chain cause the wear of the trunnions at the portions on which most of the mechanical stresses are concentrated.
- the wear of the trunnions is accelerated, which has the effect of increasing the spacing of the links, to cause an elongation of the chain and thus to reduce its life.
- the stamping step harms the modularity of the chain, especially when certain links must be replaced.
- each outer link has two flanks defining an internal space capable of receiving on each side a portion of an inner link.
- the inner link and the two flanks of the outer link have bores which, when the inner and outer links are assembled, define a passage for the introduction of a trunnion.
- the pin In the assembly position, the pin is fixed relative to the inner link - thanks to a spring ball arranged in the body of the pin - but free in rotation vis-à-vis the outer link.
- this embodiment also has disadvantages.
- the pins being fixed relative to the inner links, the mechanical stresses generated on the chain cause the wear of these pins at the portions that are continuously in contact with the inner link. This wear has the effect of increasing the spacing of the links, which causes a lengthening of the chain and therefore reduces their life.
- the object of the present invention is to propose an outer chain link and a chain comprising such an outer link free from at least one of the limitations mentioned above.
- the modular chain also in accordance with the generic definition given in the preamble above, is essentially characterized by the fact that the outer link comprises holding means able to hold the first piece and the second piece in a freely pivotable assembly position where: the first end portions (22a, 22b) of the upstream trunnion (20a) and the downstream trunnion (20b) are respectively inserted into the upstream bore (12a) and the downstream bore ( 12b) of the first piece (10), the second end portions (22'a, 22'b) of the upstream trunnion (20a) and the downstream trunnion (20b) are respectively inserted into the upstream bore (12a) and the downstream bore (12b) of the second piece (10 '), the upstream inner link (50) is positioned between the first piece (10) and the second piece (10') of the outer link (2) and
- the upstream inner link (50) is structurally associated with the outer link (2) and free to rotate around the upstream pin (20a).
- the journals are free to rotate both in the bores of the first and second outer parts, but also in the bores of the inner links.
- the journals can pivot on themselves so that the portions subject to a higher stress concentration vary.
- the wear of the trunnions is distributed over the entire circumference of the trunnions, which substantially increases the service life of the chain before the links become too far apart or when the trunnions fail and break.
- This arrangement also makes it possible to considerably increase the modularity of the chain. Indeed, it is sufficient to remove a link of the chain to disassemble the holding means so that the first and second outer parts are no longer held relative to each other and that the upstream and downstream trunnion can be extracted from the upstream bores and downstream of these first and second outer parts to release the upstream and downstream inner links.
- the holding means are able to cooperate with the first piece and the second piece so as to limit the displacement of the first piece vis-à-vis the second piece in the longitudinal direction.
- the holding means are adapted to cooperate with the first piece and the second piece so as to limit the movement of the first piece vis-à-vis the second piece in a transverse direction perpendicular to the longitudinal direction.
- the first piece and the second piece respectively comprise a first groove and a second groove, the first groove being substantially opposite the second groove when the first piece and the second piece are in the assembly position. This configuration makes it possible to reinforce the resistance of the outer chain link.
- the chain link comprises a primary rider having a body having a portion adapted to fit simultaneously into the groove of the first part and the groove of the second part when the first part and the second part are in position.
- free pivoting assembly position so as to limit the displacement, in the longitudinal direction, of the first piece vis-à-vis the second piece.
- the chain link comprises a secondary jumper capable of cooperating with the first piece and the second piece when the first piece and the second piece are in the freely pivotable assembly position so as to limit the movement of the first piece. vis-à-vis the second piece in a direction substantially perpendicular to the longitudinal direction.
- the secondary jumper has two legs extending in two planes spaced apart from each other so as to define at least one receiving space, the at least one receiving space being adapted to receive the first piece and the second piece, in the assembly position, and the two lugs being adapted to limit the displacement of the first piece vis-à-vis the second piece in a direction perpendicular to the longitudinal direction.
- the secondary jumper has two tabs extending in two planes spaced from one another so as to define a reception space, the reception space being able to receive the first piece and the second piece, in the assembly position, and the two tabs being able to limit the movement of this first piece vis-à-vis the second piece in a direction perpendicular to the longitudinal direction.
- the secondary jumper has a central lug extending in a plane defined in the at least one receiving space, the third central lug having a predetermined thickness so as to limit the approximation of the first piece vis-à-vis from the second room.
- the central shoulder has a thickness less than the thickness of the third leg.
- this central lug prevents excessive pressure being exerted by the first and second parts on the shoulder surfaces of the upstream and downstream trunnions which would have the effect of reducing their freedom of rotation inside the bores. upstream of the first and second parts.
- the primary rider and the secondary rider form a single piece functionally and structurally.
- the primary rider and the secondary rider form two separate parts functionally and structurally.
- the first piece, the second piece and the holding means have recesses which, when the first and second pieces are in the freely pivotable assembly position with the holding means, are concentric and extend in one direction. substantially perpendicular to the longitudinal direction. And, advantageously, the recess is adapted to receive a recessed pin.
- the outer link comprises a support and holding member adapted to support and maintain a cutting tool, preferably diamond.
- the support element is formed by the primary jumper or by the secondary jumper.
- the modular chain also comprises a downstream inner link positioned between the first piece and the second piece and having a bore receiving a portion of the shoulder of the downstream pin.
- the invention further relates, in a second aspect, to a method of mounting a modular chain according to the invention, comprising a succession of steps, successive or simultaneous, consisting of:
- the method consists more particularly in associating retaining means holding the first part and the second part in a freely pivotable assembly position where the first ends of the upstream trunnion and the downstream trunnion are respectively inserted into the upstream bore and the downstream bore of the first part, and the second ends of the upstream trunnion and the downstream trunnion are respectively inserted into the upstream bore and the downstream bore of the second part, so that said upstream trunnions and downstream are held in position between the first part and the second part while being free to rotate inside the upstream and downstream bores of the first and second parts.

- FIG. 7 shows, in front view, an assembly of outer chain links and links of an inner chain used for the production of a chain according to the invention.
- Figures 1a and 1b show a first outer part 10 of substantially oblong and flat shape, extending in a longitudinal direction XX.
- This first outer part 10 has, in one embodiment, a length in the longitudinal direction XX of about 45 millimeters, a width in the YY direction of about 25 millimeters and a thickness in the transverse direction ZZ of about 5 millimeters. It should also be noted that, according to an advantageous embodiment, the first external part
- the first outer part 10 is made of a material having a high hardness and resistant to abrasion, such as abramax or creuzabro 4000.
- On either side of the first outer part 10 are arranged an upstream bore 12a and a downstream bore 12b, both of circular form.
- a transverse groove 14 is also formed on the periphery of the first outer part 10, between the upstream bore 12a and the downstream bore 12b.
- the first outer part 10 further comprises, according to this embodiment a receiving recess 16 of a pin insert (described later).
- Figures 2a and 2b show, for their part, an upstream pin 20a in particular adapted to cooperate with a first outer part 10 as described above.
- the upstream pin 20a has a generally cylindrical shape with a first end portion 22a and a second end portion 22a 'also cylindrical. These first and second end portions 22a, 22a 'are separated from each other by a central shoulder 21a having a diameter greater than the diameter of the first and second end portions 22a, 22a'. There are thus formed two shoulder surfaces 24a, 24a 'on each side of the central shoulder 21a.
- the upstream trunnion 20a has a central shoulder 21a 14 millimeters in diameter as well as first and second end portions 22a, 22a '- advantageously symmetrical with respect to the median plane of this central shoulder 21a - comprising in the context of this nonlimiting example a diameter of 1 1 millimeters.
- journal having dimensions quite different without departing from the scope of the invention.
- an upstream trunnion comprising a first end portion 22a and a second end portion 22a 'having different diameters.
- the upstream pin 12a is formed of a hard material, such as XC 38 steel, for example.
- FIG. 3 represents, in perspective and in exploded view, a freely pivotable assembly of a first outer part 10, a second outer part 10 ', an upstream journal 20a and a downstream journal 20b in order to realize an outer chain link 2 according to the invention.
- the second outer part 10 ' is identical to the first outer part 10 described with reference to FIG. 1 and that the downstream journal 20b is identical to the upstream journal 20a described with reference to FIG. .
- the use of these different parts is adjustable and it is possible to switch the first outer part 10 with the second outer part 10 ', on the one hand, and the upstream journal 20a with the downstream journal 20b, on the other hand on the other hand, without generating mounting difficulties.
- This modularity is also advantageous in that it simplifies the supply of parts constituting the chain according to the invention.
- Such a configuration may, in particular, be advantageous in the context of specific applications that require the use of non-symmetrical links in the transverse and / or longitudinal median planes.
- the first end portion 22a of the upstream pin 20a is inserted into the upstream bore 12a of the first outer member 10 and the first end portion 22b of the downstream pin 20b is inserted into the downstream bore of this first outer part 10.
- the diameter of the first end portion 22a of the upstream pin 20a is slightly smaller than the diameter of the upstream bore 12a of the first outer member 10 so that, even in the freely pivotable assembly position, this first end portion 22a of the upstream pin 20a is kept free to rotate within the upstream bore 12a of the first outer member 10.
- the second end portion 22'a of the upstream trunnion 20a and the second end portion 22'b of the downstream trunnion 20b are able to be inserted while being held free to rotate within the upstream bore 12 ' a and the downstream bore 12'b of the second outer part 10 ', respectively.
- the rider 30 has a body 32 from which extend, in a direction YY, a first, a second and a third tab 34a, 34b, 34c positioned substantially opposite each other.
- first tab 34a and the second tab 34b define between them a first reception space 36 while the second tab 34b and the third tab 34c define between them a second reception space 36 '.
- This first reception space 36 like this second reception space 36 'has a thickness slightly greater than the thickness of the first and second parts 10, 10'.
- the first receiving space 36 is able to receive the edge of the first outer part 10 while the second receiving space 36 'is able to receive the edge of the second outer part 10'.
- first and second outer parts 10, 10 'in the first and second receiving spaces 36, 36' of the jumper 30 ensures a fixed positioning, in the transverse direction Z, of the first outer piece 10 screws to the second outer part 10 '. More particularly, the first leg 34a and the second leg 34c prevent the first and second outer parts 10, 10 'from moving apart in the transverse direction ZZ while the second leg 34b prevents these first and second outer parts 10, 10 'to approach each other in the transverse direction ZZ.
- the use of a second central leg 34b could be avoided by using the central shoulder 21a of the upstream pin 20a and the central shoulder 21b of the downstream pin 20b to prevent the first and second outer parts 10, 10 ' relative to each other in the transverse direction ZZ.
- this second central leg 34b prevents excessive pressure being exerted by the first and second parts 10, 10 'on the shoulder surfaces 24a, 24'a, 24b , 24'b of the upstream trunnions 20a and downstream 20b which has the effect of reducing their freedom of rotation inside the upstream bores 12a, 12'a and downstream 12b, 12'b of the first and second parts 10, 10 ' .
- the first outer part 10 has a notch 14 allowing, when this first outer part 10 is inserted into the first receiving space 36, to receive a portion of the body 32 of the rider 30.
- the second outer piece 10 ' has a notch 14' allowing, when this second outer piece 10 'is inserted into the second receiving space 36', to receive another portion of the body 32 of the rider 30.
- the notch 14 of the first outer part 10 is opposite the notch 14 'of the second outer part 10'. But it could, alternatively, not be.
- the portions of the body 32 of the rider 30 held in the inner position of the notches 14 and 14 ' can limit the relative movements of the rider 30 vis-à-vis the first and second outer part 10,10' in the longitudinal direction XX.
- Such a configuration is advantageous in that it makes it possible to use the geometry of the jumper 30 to effectively limit the movements between the jumper 30 and the first and second outer parts 10, 10 '.
- Such an aspect is essential to increase the strength and thus the service life of the sawing chains.
- first, second and third tabs 34a, 34b, 34c respectively have a first, second and third transverse recess 38a, 38b, 38c positioned facing each other so as to allow the embedding of a flush pin (not shown).
- the receiving recesses 16 of these first and second outer parts 10, 10 ' are also arranged in the axis of the first and second transverse recesses 38a, 38b.
- the jumper 30 comprises holding means 40 able to hold a cutting tool 42.
- this cutting tool 42 may consist of two pellets 42a, 42b arranged on both sides.
- it is two cutting pellets 42a, 42b may be formed in a material such as diamond.
- a cutting tool 42 consisting of a single pellet or to use a cutting tool 42 which is not in structural and functional cooperation with the rider 30.
- FIGS. 6a and 6b show an inner chain link 50 may be used in cooperation with an outer chain link as described above to achieve a chain according to the invention.
- This inner chain link 50 comprises a body 52 in which are formed two receiving bores 54 to ensure its assembly with an outer chain link upstream and a downstream chain link outside.
- This body 52 also has a substantially oblong shape and a thickness substantially equal to or less than the width of the central shoulder 21a of the upstream pin 20a and the central shoulder 21b of the downstream pin 20b.
- the two bores upstream 54a and downstream 54b have a diameter slightly greater than the diameter of the central shoulder 21a of the upstream pin 20a and the central shoulder 21b of the downstream pin 20b.
- FIG. 7 thus illustrates an assembly of three outer chain links 2 with three inner chain links 50 in order to produce a chain portion according to the invention.
- the invention also relates to a method of assembling a modular chain according to the invention.
- This method comprises a succession of steps, successive or simultaneous, of inserting the first end portion 22a of an upstream pin 20a into an upstream bore 12a formed on a first outer part 10.
- the method then consists in inserting a first end portion 22b of a downstream journal 20b in a downstream bore 12b substantially spaced from the upstream bore in the longitudinal direction of this first outer part 10.
- the method then involves associating a downstream bore 54b of a first inner link 50 with the central shoulder 21a of the upstream pin 20a so that the downstream bore 54b of the first inner link 50 is free to rotate around the shoulder. central 21a of the upstream pin 20a. It also assumes to associate an upstream bore 54a of a second inner link 5 with a central shoulder 21b of the downstream pin 20b so that the upstream bore 54a of the second outer link 50 is free to rotate around the central shoulder 21b of the downstream journal 20b.
- the method consists in associating holding means 30 holding the first outer piece 10 and the second outer piece 10 'in a free pivoting assembly position where the first ends 22a, 22b of the upstream pin 20a and the downstream pin 20b are respectively inserted into the upstream bore 12a and the downstream bore 12b of the first piece 10, and where the second ends 22'a, 22'b of the upstream pin 20a and the downstream pin 21b are respectively inserted into the bore upstream 12'a and the downstream bore 12'b of the second piece 10 '.
- this association is made so that said upstream and downstream trunnions 20a and 20b are held in position between the first outer part 10 and the second outer part 10 'while being free to rotate inside the upstream bores 12a. , 12'a and downstream 12b, 12'b of the first and second parts 10, 10 '.
- an outer chain link described with reference to Figures 1 to 7 comprises a jumper 30 for simultaneously restricting the freedom of movement of the first and second outer parts 10, 10 'in all directions.
- an outer chain link according to the invention could also comprise a primary jumper and a secondary jumper.
