Definitions
- the present invention is intended to disclose a device for coupling excavator teeth of the type used on excavating machines and the like, that is to say, machines intended to remove masses of earth and stones in public and civil engineering works.
- the teeth or excavators and the like have to fulfill a series of conditions which in some cases are contradictory and which represent on the one hand reduced manufacturing costs given the type of application for which they are to be used and the frequency of their renewal, and on the other hand high strength and the most extended life possible.
- a result of the said unsatisfactory coupling is the occurrence of different operational problems due to incorrect fitting of the tooth in the tooth-carrier, which manifests itself in high local contact pressures with the consequent wear and increase in the coupling play between the tooth and the tooth-carrier, which in turn accelerates the problems of wear and leads to a reduction in the useful life of the coupling.
- U.S. Pat. No. 4,404,760 discloses a coupling with an adapter and a point element in which the adapter has a recess with ears and a nose portion which develop from a conical form to a free rectangular end.
- the present invention has ears, which have a support function as they are capable of absorbing efforts transmitting the same from the end of the point to the adapter.
- the coupling of the present invention is precisely the result of the work carried out by the inventors in order to obtain a more balanced solution to the technical problems which arise on the teeth of the excavators.
- the result of the investigations and work performed by the inventors is that of obtaining a device for coupling excavator teeth which combines in a satisfactory manner the characteristics of mechanical robustness necessary in the part with significant ease of manufacture and with an extended life of the coupling.
- the combination of these three types of principal coupling is obtained by producing a first area of coupling between tooth and tooth-carrier which comprises seatings which open on the edge of the tooth-carrier and which have internally a double straight guide which assumes the form of a profile which has in cross-section a double straight stepped region and which extends through the sides of the tooth-carrier parallel to the axis of the part.
- the tooth has projecting areas complementary to the said parts having a double stepped guide structure, so that, after their introduction, the aforesaid projecting areas are properly engaged in the double guide recesses, providing multiple areas of coupling between the tooth and the tooth-carrier in a transverse arrangement at 90° which provide a very effective coupling with many areas of contact between the two parts.
- the immediate area of coupling between tooth and tooth-carrier has symmetrical revolution surfaces opposed to one another, assuming the form of areas of cylindrical or frustoconical surfaces, arranged on the start of the tooth coupling rod intended to coincide in the complementary opening of the tooth-carrier and, preferably, in an arrangement such that one of the revolution surfaces is arranged on the upper portion of the part and the other, symmetrically opposed to the first, is arranged on the lower portion of the part.
- the third area of coupling between tooth and tooth-carrier combined with those described above, constitutes a terminal journal of the coupling projection of the tooth, which assumes a prismatic structure with the edges rounded and the axis of which coincides with the axis of the part.
- the upper and lower ends of the seating for the retaining pin or bolt will optionally be closed by means of covers intended to preserve the seating of the cotter pin as far as possible, facilitating its subsequent disassembly at the right moment.
- the retaining bolt or pin will have a structure consisting of a base body carrying a centering extension which is joined to the base body by vulcanization. In order to permit the inspection of the correctly introduced state of the cotter pin and likewise certain manipulations which may be necessary for extraction, the tooth will have in one of its lateral fitting lugs an opening which coincides with the position of the bolt.
- FIGS. 3 to 6 are cross-sections through the tooth coupling which correspond to the double, stepped guide area.
- FIG. 15 shows a view in side elevation of the assembly of tooth and tooth-carrier.
- FIG. 20 shows a perspective view of the tooth which incorporates the coupling device of the present invention.
- FIGS. 28 and 29 respectively show a longitudinal section through the assembly of tooth-carrier and tooth according to the variant in FIG. 21 .
- FIGS. 32 and 33 show respective sections through bolts for retaining the tooth, according to the present improvements.
- FIGS. 35 to 40 are sections through the section planes indicated in FIG. 34 .
- FIG. 42 shows a longitudinal section according to the section plane indicated in FIG. 41 .
- FIG. 43 shows a second longitudinal section through the section plane indicated in FIG. 44 , perpendicular to the section indicated in FIG. 42 .
- FIG. 45 shows a detail in section of the assembly of tooth and tooth-carrier according to the present invention, showing a variant of the edge where the tooth and tooth-carrier coincide.
- FIG. 46 shows a detail in section illustrating the stresses generated in the coupling in FIG. 45 .
- the coupling device comprises firstly the tooth-carrying element designated generally by 1 , carrying the male coupling which consists of an area 2 for coupling with the tooth and an area 3 for coupling with the active edge of the bucket of the excavator.
- the area 3 has a basically fork-shaped structure heaving arms 4 and 5 with a straightedged indentation 6 for coupling it to the active edge of the bucket by welding or other means.
- the projecting portion 3 has, as is customary in these coupling devices, a structure of decreasing section from the starting face 7 of the projection 2 to the terminal straight end 8 .
- the coupling 1 has on each of its sides respective openings 9 and 10 which start on the face 7 and which extend to the end 3 for coupling with the edge of the bucket, it being characteristic of the said openings that both have a structure based on a double internal guide by means of transverse straight steps, as will be seen in FIGS. 3 to 6 , in which it will be observed that the openings 9 and 10 have rectilinear generatrices parallel to the axis of the part, assuming a form in cross-section in which there is constituted a double straight guide with intermediate step, having, for example, for the guide opening 9 the straight, parallel walls 11 and 12 of the first straight guide and the walls of the straight guide of the bottom of the indentation 9 which are indicated by 13 and 14 .
- the straight guides of each side are separated by respective straight steps 15 and 16 .
- the structure of the indentation 10 is identical to that explained for the indentation 9 , so that it will not be explained in greater detail.
- the provision of the double stepped guide improves the coupling between tooth and tooth-carrier by increasing the effective areas of contact between the two parts in the initial assembly.
- the tooth 17 , FIGS. 15 and 16 has projecting lateral wings 18 and 19 of a shape complementary to that of the openings with double stepped guide 9 and 10 , as can be seen in FIGS. 15 and 16 , 19 and 20 .
- the coupling projection 2 has, after its start from the face 7 of the part 1 , an area of coupling by means of revolution surfaces, which are formed by two surfaces 20 and 21 , FIGS. 7 to 10 , which may be constituted by frustoconical or cylindrical surfaces arranged in opposition to one another and symmetrical with respect to tile axis of the part, which coincides with the axis of symmetry of the sections illustrated.
- the lateral grooves 22 and 23 extend along the said coupling area, ending in the most remote section illustrated in FIG. 10 , in which the two revolution surfaces opposed to each other, indicated in this case by 20 ′ and 21 ′, are practically joined by their ends.
- the third principal guiding area is formed by the rod 24 at the free end of the coupling area 2 , which assumes a straight prismatic structure with rounded edges, as will be seen in FIG. 11 .
- the coupling is completed by means of a transverse cotter pin 25 which is intended to retain the tooth 17 and which is housed in a transverse opening 26 which opens in the part 1 in the immediate vicinity of the face 7 .
- FIG. 21 indicated generally by 27 , there can be seen a structure varying slightly in the rear extensions 28 and 29 , the first of which represents a substantially obtuse-angled structure forming with the extension 29 an indentation at a certain angle with respect to the horizontal, intended for the incorporation of the tooth-carrier on the edge of a bucket or scoop of the earth-moving machine.
- the seating 30 for the bolt or cotter pin which, as in the version in FIG. 1 , is provided in the body portion of the tooth-carrier and not in the part termed the “nose” 31 , also has wide rebates 32 and 33 on its ends which, combined with a more reduced length of the bolt, as can be observed in FIGS.
- the rectilinear construction of the bolt 36 which has been shown in FIG. 32 , may be modified in the form of a gently arched structure, as can be seen in FIG. 33 , in which is shown a bolt 40 provided with a certain longitudinal curvature, which is provided with a similar centering insert 41 with the central projection 42 , and the union with a similar resilient area 43 being excepted.
- the variant of the tooth-carrier shown in FIG. 21 has lateral centering grooves of symmetrical type 45 and 46 , like the corresponding ones in FIG. 1 and following figures, the version with double retaining bolt also being shown, the seatings 47 and 48 for the latter being seen in FIG. 23
- FIGS. 28 and 29 can be seen the coupling of the tooth 49 in the tooth-carrier according to the variant in FIG. 21
- the present invention likewise provides for a special constitution of the edge where the tooth-carrier and the tooth coincide, as can be seen in the figurers and, in particular, in FIG. 21 and in FIGS. 45 and 46 .
- the edge 60 of the tooth-carrier is not perpendicular to the median plane P of the tooth, but forms a certain angle ⁇ with respect to the perpendicular p as shown in FIG.
