Description

L'invention est relative à un dispositif de verrouillage portant une dent, un adaptateur et une clavette de verrouillage destinée à verrouiller la dent sur l'adaptateur.The invention relates to a locking device carrying a tooth, an adapter and a locking key for locking the tooth on the adapter.

L'invention est également relative à une clavette de verrouillage destinée à verrouiller une dent sur un adaptateur.The invention also relates to a locking key for locking a tooth on an adapter.

L'invention est particulièrement utile pour équiper un godet ou un outil de travaux publics apte à être monté au bout d'une pelle excavatrice hydraulique ou d'une chargeuse.The invention is particularly useful for equipping a bucket or a public works tool capable of being mounted at the end of a hydraulic excavator or a loader.

Le document US 5 233 770 décrit une clavette de verrouillage en une seule pièce destinée à retenir une dent sur un adaptateur. Cette clavette présente une forme sensiblement parallélépipédique avec une partie formant ressort s'étendant à partir de l'extrémité distale vers le haut. Une butée de retenue est prévue pour empêcher la perte accidentelle de la clavette. Lors du démontage, il est nécessaire de casser cette butée de retenue en appliquant une force suffisante, avant d'extraire la clavette de l'assemblage.The document US 5,233,770 discloses a one-piece locking key for retaining a tooth on an adapter. This key has a substantially parallelepipedal shape with a spring portion extending from the distal end upwards. A retaining stop is provided to prevent the accidental loss of the key. During disassembly, it is necessary to break this retaining stopper by applying sufficient force, before extracting the key of the assembly.

Ainsi, après avoir cassé la butée de retenue de la clavette du document US 5 233 770 , il devient nécessaire d'utiliser une clavette neuve à chaque remplacement de dent.Thus, after breaking the retaining stop of the key of the document US 5,233,770 , it becomes necessary to use a new key every tooth replacement.

Un premier but de l'invention est de fournir un dispositif comportant une clavette de verrouillage, dans lequel la clavette de verrouillage peut être réutilisée lors d'un changement de dent.A first object of the invention is to provide a device comprising a locking key, in which the locking key can be reused during a tooth change.

Un deuxième but de l'invention est de permettre la fabrication de la clavette de verrouillage par des moyens simples et économiques, de préférence par découpage dans une tôle, de manière à obtenir une pièce d'un seul tenant.A second object of the invention is to allow the manufacture of the locking key by simple and economical means, preferably by cutting into a sheet, so as to obtain a piece in one piece.

Le document US 2 190 845 décrit une clavette de verrouillage en une seule pièce destinée à retenir une dent 12 sur un adaptateur 15. La figure 4 du document US 2 190 845 représente une clavette de verrouillage monobloc 40 avec un corps 50 et une lame de ressort 52. Le corps 50 de la clavette de verrouillage monobloc est en appui sur des faces d'appui 40 et 41 de la dent 12, tandis qu'une projection ou protubérance convexe 53 de la lame de ressort 52 est en appui sur une dépression concave 45R de l'adaptateur 15.The document US 2,190,845 discloses a one-piece locking key for retaining a tooth 12 on an adapter 15. Figure 4 of the document US 2,190,845 represents a one-piece locking key 40 with a body 50 and a leaf spring 52. The body 50 of the one-piece locking key bears on support faces 40 and 41 of the tooth 12, while a projection or convex protuberance 53 of the leaf spring 52 bears against a concave depression 45R of the adapter 15.

Mais cette projection ou protubérance convexe 53 de la lame de ressort 52 assure également le verrouillage de la clavette 40 dans le logement 45R de l'adaptateur 15 en remplissant ainsi deux fonctions.But this projection or convex protuberance 53 of the leaf spring 52 also ensures the locking of the key 40 in the housing 45R of the adapter 15 thus fulfilling two functions.

La fonction "verrouillage" de la clavette 40 dans le logement 45R de l'adaptateur 15 est assurée de manière satisfaisante pour maintenir en position la clavette en absence d'effort.The "lock" function of the key 40 in the housing 45R of the adapter 15 is satisfactorily provided to maintain the key in position in the absence of effort.

Par contre, la fonction "appui" de la clavette 40 n'est pas assurée de manière satisfaisante pour la reprise des efforts entre la dent 12 et l'adaptateur 15, car la projection ou protubérance convexe 53 de la lame de ressort 52 ne peut pas assurer un clavetage efficace.On the other hand, the "support" function of the key 40 is not satisfactorily provided for the recovery of the forces between the tooth 12 and the adapter 15, since the projection or convex protuberance 53 of the leaf spring 52 can not not ensure effective keying.

En effet cette projection ou protubérance convexe 53 de la lame de ressort 52 ne résiste pas à des efforts dépassant la limite élastique de la lame de ressort, laquelle est soumise à une déformation permanente et perd ensuite la fonction "verrouillage": l'assemblage se déchausse et ne fonctionne plus.Indeed, this projection or convex protuberance 53 of the leaf spring 52 does not withstand forces exceeding the elastic limit of the leaf spring, which is subjected to permanent deformation and then loses the function "lock": the assembly is loosens and does not work anymore.

Un troisième but de l'invention est de perfectionner la clavette de verrouillage réutilisable de la figure 4 du document US 2 190 845 , pour que la fonction "appui" de la clavette soit assurée de manière satisfaisante pour la reprise des efforts entre la dent et l'adaptateur.A third object of the invention is to improve the reusable locking key of FIG. US 2,190,845 , so that the function "support" of the key is satisfactorily provided for the recovery of efforts between the tooth and the adapter.

L'invention est relative à un dispositif de verrouillage comportant un adaptateur, une dent et une clavette monobloc de verrouillage destinée à verrouiller la dent sur l'adaptateur, dans laquelle la dent comporte deux passages présentant chacun une face d'appui de clavette, l'adaptateur présente un passage avec une face d'appui de clavette et un logement, caractérisé en combinaison par le fait que la clavette présente un contour d'appui intérieur, une lamelle élastique de verrouillage extérieure formant ressort et deux surfaces d'appui prévues de part et d'autre de la lamelle élastique de verrouillage formant ressort et par le fait que des conformations adaptées sont prévues sur l'adaptateur et la dent, de manière à séparer les fonctions «appui» et «verrouillage».The invention relates to a locking device comprising an adapter, a tooth and a locking monobloc key for locking the tooth on the adapter, wherein the tooth comprises two passages each having a key bearing face, The adapter has a passage with a key bearing face and a housing, characterized in that the key has an inner bearing contour, an elastic spring-forming outer resilient lamella, and two provided bearing surfaces. on either side of the spring-loaded resilient spring blade and that Adaptations are provided on the adapter and the tooth, so as to separate the "support" and "locking" functions.

En référence aux figures 1 à 3, les éléments identiques ou fonctionnellement équivalents sont repérés par des chiffres de référence identiques.With reference to Figures 1 to 3 identical or functionally equivalent elements are identified by identical reference numerals.

Sur la figure 1, un dispositif selon l'invention comporte un adaptateur 1, une dent 2 et une clavette 3.On the figure 1 , a device according to the invention comprises an adapter 1, a tooth 2 and a key 3.

L'adaptateur 1 comporte une partie arrière 1 a destinée à être fixée à un godet excavateur ou à un outil de travaux publics non représenté, et une partie avant 1 b en forme de nez.The adapter 1 comprises a rear portion 1a intended to be attached to an excavator bucket or a public works tool not shown, and a front portion 1b shaped nose.

La partie avant 1 b est en correspondance de forme avec une empreinte femelle 2b située à l'arrière de la pointe 2a de la dent 2.The front portion 1b is in correspondence of shape with a female cavity 2b located at the rear of the tip 2a of the tooth 2.

L'empreinte femelle 2b est limitée par deux conformations rentrantes 2c de contours évasés.The female footprint 2b is limited by two re-entrant conformations 2c of flared contours.

Les conformations rentrantes 2c sont en correspondance de forme avec deux ailettes 1 c de l'adaptateur 1.The re-entrant conformations 2c are in shape correspondence with two fins 1 c of the adapter 1.

Ainsi, lorsque les parties en correspondance de forme sont appliquées les unes contre les autres après verrouillage de l'assemblage par la clavette 3, les efforts résultants du travail de la dent 2 sont transmis à l'adaptateur 1 et au godet par leurs surfaces en correspondance de forme.Thus, when the form-fitting parts are applied against each other after locking the assembly by the key 3, the efforts resulting from the work of the tooth 2 are transmitted to the adapter 1 and the bucket by their surfaces. form correspondence.

La clavette 3 présente de préférence une épaisseur constante et des flancs parallèles, de sorte que la fabrication de la clavette peut être réalisée par un moyen de découpage dans une tôle, par exemple par oxycoupage, par découpe laser, par découpe à jet d'eau ou tout autre moyen de découpe permettant d'obtenir le contour de clavette représenté aux figures 1 à 3.The key 3 preferably has a constant thickness and parallel flanks, so that the manufacture of the key can be performed by a cutting means in a sheet, for example by flame cutting, laser cutting, water jet cutting or any other cutting means for obtaining the key contour shown in FIGS. Figures 1 to 3 .

De préférence, la clavette 3 présente un contour d'appui cylindrique intérieur 3a de rayon constant, par exemple voisin de 100 mm et une lamelle de verrouillage latérale extérieure 3b formant ressort.Preferably, the key 3 has an inner cylindrical bearing contour 3a of constant radius, for example close to 100 mm and an outer lateral locking strip 3b forming a spring.

De part et d'autre de la lamelle 3b élastique de verrouillage formant ressort, on prévoit deux surfaces d'appui 3c en forme de secteur cylindrique d'un même cylindre géométrique de rayon supérieur au rayon de la partie cylindrique intérieure 3a.On either side of the resilient spring locking slat 3b, two cylindrical sector shaped bearing surfaces 3c of the same geometrical cylinder having a radius greater than the radius of the inner cylindrical portion 3a are provided.

L'axe A du secteur cylindrique 3a d'appui et l'axe C des secteurs cylindriques 3c d'appui sont décalés de manière que la clavette 3 présente une forme généralement courbe et évasée, à l'exception de la lamelle 3b formant ressort.The axis A of the bearing cylindrical sector 3a and the axis C of the bearing cylindrical sectors 3c are offset so that the key 3 has a generally curved and flared shape, with the exception of the leaf 3b forming a spring.

De manière à permettre une coopération et une solidarisation de la dent 2 et de l'adaptateur 1, on prévoit des conformations adaptées sur l'adaptateur 1 et la dent 2 : ainsi, la dent 2 est pourvue de deux secteurs cylindriques 4 d'appui de même rayon que les appuis cylindriques 3c de la clavette 3 ; et l'adaptateur 1 est muni d'un logement central 5 et d'un contour d'appui cylindrique 6 de rayon notablement inférieur au rayon du secteur d'appui cylindrique 3a.In order to allow a cooperation and a joining of the tooth 2 and the adapter 1, adapted conformations are provided on the adapter 1 and the tooth 2: thus, the tooth 2 is provided with two cylindrical bearing sectors 4 of the same radius as the cylindrical supports 3c of the key 3; and the adapter 1 is provided with a central housing 5 and a cylindrical bearing contour 6 of radius substantially less than the radius of the cylindrical bearing sector 3a.

Le rayon du secteur d'appui cylindrique 3c et des surfaces cylindriques 4 d'appui peut être quelconque, dès lors qu'il est supérieur d'au moins cinq pour cent au rayon du secteur d'appui cylindrique 3a.The radius of the cylindrical bearing sector 3c and cylindrical bearing surfaces 4 may be arbitrary, provided that it is at least five percent greater than the radius of the cylindrical bearing sector 3a.

L'invention s'étend également au cas où le rayon des secteurs d'appui cylindriques 3c et des surfaces d'appui 6 est infini, c'est-à-dire au cas où ces secteurs et surfaces sont plans et coplanaires.The invention also extends to the case where the radius of the cylindrical bearing sectors 3c and the bearing surfaces 6 is infinite, that is to say in the case where these sectors and surfaces are planar and coplanar.

Sur la figure 2, la clavette 3 est insérée par le passage supérieur de la dent 2 et repose par son rayon intérieur 3a sur le contour cylindrique 6 de l'adaptateur 1.On the figure 2 , the key 3 is inserted through the upper passage of the tooth 2 and rests by its inner radius 3a on the cylindrical contour 6 of the adapter 1.

L'extrémité inférieure de la clavette 3 est en appui sur le chanfrein inférieur de délimitation du logement central 5.The lower end of the key 3 is supported on the lower chamfer of delimitation of the central housing 5.

La poursuite du mouvement de la clavette 3 dans les conformations de l'adaptateur 1 et de la dent 2 exige l'application d'un effort modéré, par exemple par frappe à l'aide d'un marteau sur la face supérieure de la clavette 3.The continued movement of the key 3 in the conformations of the adapter 1 and the tooth 2 requires the application of a moderate force, for example by striking with a hammer on the upper face of the key 3.

L'application de cet effort assure simultanément la pénétration complète de la clavette 3 dans le passage inférieur de la dent 2 et la mise en place de la lamelle 3b formant ressort dans le logement central 5, le tout dans un mouvement d'enroulement du secteur d'appui cylindrique 3a autour de la conformation 6 de l'adaptateur 1.The application of this force simultaneously ensures the complete penetration of the key 3 in the lower passage of the tooth 2 and the establishment of the leaf spring 3b in the central housing 5, all in a winding movement of the sector of cylindrical support 3a around the conformation 6 of the adapter 1.

En référence à la figure 3, après insertion complète de la clavette 3, les centres des secteurs cylindriques d'appui 3a et 6 sont alignés avec le point de contact de la clavette 3 et de la conformation 6.With reference to the figure 3 , after complete insertion of the key 3, the centers of the bearing cylindrical sectors 3a and 6 are aligned with the point of contact of the key 3 and the conformation 6.

Le point T de contact et d'appui de la clavette 3 et du contour cylindrique d'appui 6 de l'adaptateur 1 sont ainsi alignés avec le centre B du contour cylindrique 6 et le centre A de la face intérieure cylindrique 3a de la clavette 3, de manière à éviter tout effort dévié ou moment susceptible de déchausser la clavette 3 à l'encontre du ressort 3b appliqué dans le logement 5.The point T of contact and support of the key 3 and the cylindrical bearing contour 6 of the adapter 1 are thus aligned with the center B of the cylindrical contour 6 and the center A of the cylindrical inner face 3a of the key 3, so as to avoid any deflected force or moment likely to loosen the key 3 against the spring 3b applied in the housing 5.

Le contact d'appui entre les surfaces 3c et 4, ainsi que le contact d'appui au point T, assure une solidarisation du dispositif selon l'invention et permet une transmission intégrale des efforts des dents 2 aux adaptateurs 1 et aux godets ou à l'outil correspondant.The bearing contact between the surfaces 3c and 4, as well as the bearing contact at the point T, secures the device according to the invention and allows an integral transmission of the forces of the teeth 2 to the adapters 1 and the buckets or to the corresponding tool.

Lors de l'utilisation, les jeux mécaniques entre la dent 2 et l'adaptateur 1 engendrent des petits mouvements qui ont tendance à déplacer la clavette 3.In use, the mechanical clearances between the tooth 2 and the adapter 1 cause small movements which tend to move the key 3.

Selon l'invention, le ressort 3b exerce constamment un verrouillage élastique sur la face supérieure du logement 5 de l'adaptateur 1 et empêche ainsi le recul de la clavette 3 et son dégagement, en repoussant la clavette 3 en position dans la dent 2.According to the invention, the spring 3b constantly exerts an elastic locking on the upper face of the housing 5 of the adapter 1 and thus prevents the recoil of the key 3 and its disengagement, by pushing the key 3 into position in the tooth 2.

Le poids propre de la clavette 3 est faible et ne peut pas exercer sur le ressort 3b une action susceptible de le déformer.The self weight of the key 3 is low and can not exert on the spring 3b an action likely to deform.

Pour assurer le démontage de la clavette 3, il suffit d'appliquer un effort modéré sur la partie inférieure de la clavette 3, par exemple par frappe à l'aide d'un marteau.To ensure the disassembly of the key 3, it is sufficient to apply a moderate force on the lower part of the key 3, for example by striking with a hammer.

Cet effort repousse radialement intérieurement la lamelle de verrouillage latérale extérieure 3b formant ressort et repousse ainsi la clavette 3 vers le haut, en augmentant la mise en compression du ressort 3b par glissement de son extrémité sur une pente correspondante du logement 5.This force radially pushes internally the outer lateral locking strip 3b forming spring and thus pushes the key 3 upwards, increasing the compression of the spring 3b by sliding its end on a corresponding slope of the housing 5.

La déformation correspondante de la clavette 3 permet son dégagement hors du logement 5 jusqu'à sortie complète de la clavette 3.The corresponding deformation of the key 3 allows its release from the housing 5 to complete output of the key 3.

La sortie de la clavette 3 s'effectue alors par déroulement progressif du secteur cylindrique 3a sur le contour cylindrique 6 de l'adaptateur 1.The output of the key 3 is then performed by progressive unwinding of the cylindrical sector 3a on the cylindrical contour 6 of the adapter 1.

Ainsi, grâce à l'invention, on peut effectuer le changement des dents usées en réutilisant la même clavette 3 selon l'invention, sans devoir endommager une partie de cette clavette 3.Thus, thanks to the invention, it is possible to change the worn teeth by reusing the same key 3 according to the invention, without having to damage part of this key 3.
