Definitions

  • the present invention relates to a system for coupling a tooth to its holder in an excavating machine or the like, in which the holders are attached to the bucket or shovel of the machine.
  • the tooth holders comprise a frontal protrusion or nose
  • in the tooth holder guide means are provided so that the ears of the tooth in horizontal position slide vertically guided by the dies of their ears to a point where the axis of the tooth cavity is aligned with the axis of the nose of the tooth holder, at which point the tooth moves in the direction of these axes and in the direction of bringing the tooth closer to the tooth holder until the teeth of the teeth are positioned in complementary housings of the tooth holder located at the level of the dies, after which a space is created between the guide means of the tooth holder and the tooth dies, in which a pin is inserted.
  • the new tooth is attached to the adapter by front entry of its hollow on the nose of the adapter, following a substantially horizontal path that coincides with the geometric axes corresponding to the largest dimension of the adapter and tooth elements, without these axes being considered as symmetry since these elements are not symmetrical with respect to an axis, as observed in patents ES 9801404 (Metallogeny), EP 0835963 (Metallogeny), US 4,192,089 (Orenstein), US 3520,224 (Hensley), US 5,074,062 (Esco), ES 9902161 (Metallogeny), ES 9801257 (Metallogeny) and others.
  • the tooth in its coupling to the tooth holder, must point its hole inclined against the nose of the tooth holder until it passes a horizontal step of the tooth, at which point the tooth turns over the nose of the tooth holder and slides to the bottom of the tooth.
  • These systems of coupling the tooth to the adapter are especially difficult to carry out in large sizes, such as those used in mining and often have to be carried out in uncomfortable space situations.
  • the retention pins work in shear, for which reason they are reusable on rare occasions.
  • the system object of the invention has been developed, according to which guide means are provided for the teeth so that the ears of the tooth in horizontal position slide vertically guided by the dies of their ears to a point in the that the axis of the tooth cavity is aligned with the axis of the nose of the tooth holder, at which point the tooth moves in the direction of these axes and in the direction of bringing the tooth closer to the tooth holder until the dies of the ears are located of the tooth in complementary housings of the tooth holder located at the level of the dies, after which a space is created between the means of guiding the tooth holder and the teeth of the tooth, in which a pin is inserted.
  • a preferred embodiment of the invention consists in that the tooth holder symmetrically presents on its flanks a wide vertical slot, open superiorly and closed inferiorly by a support step, which extends transversely, as a continuation of said support step, in an open recess and it is furrowed at its bottom by a minor groove that, when it reaches the support step, continues in a through hole, while the tooth has a dimensioned to slide vertically across the wide area at the free end of the inner face of each ear vertical slot of the adapter to the support step and move horizontally to lodge in the open recess of the same, leaving the die of the tooth's ear free the passage through the minor slot for the insertion of a pin equipped with a complementary retainer with a recess centrally provided at the bottom of said minor groove.

  • Figure 1 shows, in its upper part, the coupling end portion of a tooth holder 1 complementary to the end portion of a tooth 2, represented in the lower part.

  • Figures 2 and 5 show how the pin 11 is located, observing, on the one hand, that it is attached on one side against the coplanar walls 4A of the wide vertical slot 4 and 8A of the minor slot 8, while on the opposite side, die 14 is applied, with the result that the pin is only subjected to compressive stresses, while, on the other hand, pin 11 is positioned centrally at the height of the recess 10 of the tooth holder 1 in the one that engages the retainer 15, with which it is housed to the pin 11 of the risks of being damaged during work.
  • figures 6 to 10 show various stages of mounting the tooth 2 in the tooth holder 1 and the insertion of the pin 1 1, stages that are not described because the figures are sufficiently explicit.

Abstract

L'invention concerne un système de couplage d'une dent dans le porte-dents d'une excavatrice ou analogue. Dans le porte-dents, un dispositif de guidage est prévu pour que les oreilles de la dent en position horizontale glissent verticalement, guidées par les dés de leurs oreilles jusqu'à un point dans lequel l'axe du creux de la dent est alignée sur l'axe du nez du porte-dents. A ce moment, la dent se déplace en direction desdits axes et dans le sens dans lequel la dent s'approche du porte-dents jusqu'à ce que les dés des oreilles de la dent soient situés dans des logements complémentaires du porte-dents situés au niveau des dés, ce qui permet de créer, entre le dispositif de guidage du porte-dents et les dés, un espace dans lequel on insère une fiche.
