Definitions
- the present invention relates to a coupling system for the teeth of an excavator, especially for the teeth constituted by the association of a tooth-bearing element, which is fixed on the active edge of the excavator's shovel or similar, with a tooth element, which is attachable to the aforementioned tooth holder element and retainable therein by means of one or more pins.

- a feature of the invention consists in that the two extreme sections of the straight section of each of the ears of the tooth element, affect the intermediate section with an angle of a value between approximately 10 ° and 40 °.
- the invention comprises that the differentiated intermediate section of the straight section of the ears of the tooth element may adopt a curvilinear configuration or a rectilinear configuration, without excluding other composite configurations (mixed, broken, etc.).
- the invention comprises that the extreme sections of the straight section of each of the ears can adopt a rectilinear or curvilinear configuration, without excluding other possible ones, comprising the cases in which both extreme sections are of the same or of different configuration, of equal or different length in any of the preceding cases, and with angle of incidence on the differentiated intermediate sections equal or different for the two extreme sections of the same straight section.
- Another feature of the invention is that the two ears of the same tooth element can be specularly symmetrical or with respect to a point.
- ears of the tooth element have diametrically opposed holes that, located in one of the end sections or in the differentiated intermediate section, are aligned in correspondence with a hole that crosses the cantilever boss of the element of toothpick
- the two minor sides of the straight section of the ears of the tooth element are rectilinear and substantially parallel to each other and that the straight section of each ear of the tooth element has an equal width throughout its length, however, it may have one or more areas of reduced length and width different from the prevailing width.
- another feature of the invention is that in the ears of the tooth element the longer lengths are facing the direction of the efforts to resist.
- Figure 1 depicts, in angular exploded perspective, the tooth and tooth holder elements according to the invention, seen by their mutual coupling parts.
- Figure 2 represents, in side elevation, the tooth and tooth elements of the previous figure in their coupling position.
- Figure 3 represents, on the upper floor, the tooth and tooth elements of the previous figure.
- Figure 4 represents, schematically, a coupled set of tooth and tooth holders according to the invention, in which a downward vertical effort is assumed applied to the tip of the tooth, the resulting reactions caused by said effort being plotted.
- Figure 5 represents a schematic section along the line VV of Figure 4, in which the effects that the downward vertical force determine on the ears of the tooth element are shown.
- Figure 6 represents, analogously to the case of figure 4, the set of tooth and tooth holders in which the vertical effort is supposed to be applied upwards on the tip of the tooth, the reactions caused by said effort being enhanced.
- Figure 7 represents a schematic section according to line VI I-VI I of Figure 6, in which the effects on the ears of the tooth element determine the upward vertical stress are shown.
- Figure 8 represents a section analogous to that of Figures 5 and 7, in which the location of the ears of the tooth element, housed in the recesses of the tooth holder element, and the boundary angles between which functionally must be found are shown the end sections of the ears of the tooth element with respect to the vertical perpendicular to the central axis thereof, three possibilities having been indicated in strokes to position the housing for the coupling retaining pin.
- Figure 9 represents a section similar to that of the previous figure, in which the differentiated intermediate section and the end sections of the straight section of both ears of the tooth element are of rectilinear configuration and the angle of incidence of the extreme sections on the differentiated intermediate section is constant.
- Figure 10 represents a section analogous to that of the previous figure in which the ears of the tooth element are symmetrical with respect to a point, the straight section of the ears presenting its extreme, rectilinear and different length sections in each one of them and in alternating position those of one with respect to the other, and its differentiated intermediate curvilinear section, the situation of the housing for the retention pin has also been indicated in strokes.
- Figure 11 represents a section similar to that of Figure 10 in which the ears of the tooth element are specularly symmetrical presenting rectilinear and of different length their end sections and its differentiated intermediate section is curvilinear, being in this case, in the lower position the short end sections, being able to be located in a lower position in another case, not specifically represented.
- Figure 12 represents, schematically, some of the various ways that it can take a straight section of an ear of the tooth element.
- Figure 13 represents, schematically, half of a section analogous to that of Figures 5, 7 and 8 to 11, in which a straight section of an ear of the tooth element is shown in the case in which it presents its differentiated sections intermediate of different width and the bottom of the recess of the element of toothpick, which presents a complementary protrusion of the depression of the differentiated intermediate section.
- Figure 1 shows, in an angularly exploded perspective, an assembly formed by a tooth holder element 1 and a tooth element 2.
- the toothholder element 1 is constituted by a central core 3 from which axially, on the one hand, a fork 4, for the coupling of the toothholder element 1 on the active edge of the excavator blade or bucket, and, on the other hand , a projection in cantilever 5, or nose, in a prismatic manner.
- the central core 3 has, on both sides, two rectilinear recesses 6 and, transversely, a hole for the accommodation of a retaining pin, both dispositions located so as not to reduce the section of the nose 5.
- the tooth element 2 is constituted by a central core 7 which, axially, comprises a central housing 8, from which from its mouth 9 there are two straight ears 10, and a working tip 11.
- the rectilinear ears 10 of the tooth element 2 are housed in the rectilinear recesses 6 of the tooth holder element 1, the coupling being maintained , in an exemplary embodiment, by means of a step 12, constituted by holes aligned in the rectilinear ears 10 of the tooth element 2 and in the central core 3 of the holder element 1, into which a retaining pin 13 is inserted.
- the object of the invention consists, as shown in Figures 5 and 7, in relation to Figures 4 and 6, in the fact that the straight section of each of the rectilinear ears 10 of the tooth element 2, which is in a concave and substantially complementary part 14 of the convex profile of the bottom 15 of the rectilinear recesses of the holder element 1, it presents, as detailed in Figure 8, two end sections 10A that are convergently joined in a differentiated intermediate section 10B of the above.
- said sections 10A and 10B have been separated by lines of imaginary lines M.
- an effort Fs applied vertically downwards on the working tip 11 of the tooth element 2 determines reactions Rs1 on the nose 5 and Rs2 on the upper edge of the rectilinear recesses 6, which they give rise to a component Cs, which tends to apply the end sections 10A of the rectilinear ears 10 against the bottoms 15 of the rectilinear recesses 6.
- the effort Fi is applied vertically upwards at the working tip 11 of the tooth element 2, in which case the reactions are Ri1 and Ri2 and the component is Ci.
- the trend of the end sections 10A of the rectilinear ears 10 of the tooth element 2 against the bottoms 15 of the rectilinear recesses 6 has been drawn.
- Figure 9 shows the case in which, in the straight section of the rectilinear ears 10, the end sections 10A are rectilinear and equal and the differentiated intermediate section 10B is rectilinear, also having represented a possible step 12 for a retention pin.
- Figures 10 and 11 show the case in which the rectilinear ears 10 have their end sections 10A and 10C, rectilinear, of different length and the same angle of incidence on the differentiated intermediate sections 10B, being located in Figure 10 according to a point symmetry, while in figure 11 the symmetry is specular. In the case of this last figure, it can adopt an inverse position, in which the larger end sections 10A are located below the smaller end sections 10C. In all cases, in the rectilinear ears 10 of the tooth element 2 the longer end sections 10A will face the direction of the efforts to resist.
- Figure 12 shows some of the various variants of the straight section that can be adopted in the making of the rectilinear ears 10.
- the straight section of a rectilinear ear 16 can be seen, presenting its end sections 16A in a curvilinear shape and the differentiated intermediate section 16B in curvilinear form of curvature different from that of the end sections 16A.
- the straight section of the rectilinear ear 17 has its end sections 17A in curvilinear form and its differentiated intermediate section 17 in rectilinear form.
- the straight section of the rectilinear ear 18 has its end sections 18A in rectilinear form and its differentiated intermediate section 18B in a curvilinear form.
- the straight section of the rectilinear ear 19 has its end sections 19A in a rectilinear form, as does its differentiated intermediate section 19B.
- the straight section of the rectilinear ear 19 has its end sections 19A in a rectilinear form, as does its differentiated intermediate section 19B.
- figure 13 half of a section of the coupling of the tooth-holder element 1 is shown with the tooth element 2 analogous to that of figures 5, 7 and 8 to 11, in which a straight section of one ear is observed rectilinear 20 in the case where its differentiated intermediate section 20B has a different width than the end sections 20A and the bottom 15 of the rectilinear recess 6 of the holder element 1 has a protuberance 21 complementary to the depression 22 of the differentiated intermediate section 20B.
- a nose 5 that evolves from a hexagon, it allows it to be adapted without removing material from the nose 5 to implement rectilinear ears. In this way, the robustness of the nose 5 is not reduced, nor is the number of edges increased, thus reducing the risk of stress concentrations and achieving a simple but effective geometry.
- the ears are completely closed, working under compression when a vertical effort is applied to the assembly, either upper or lower.
