Definitions

  • the invention relates to the technical sector of equipment of public works machines with buckets, buckets or other receptacles likely to scrape, remove, move materials or others for their evacuation from a given place to other operating posts using public works machinery.
  • connection of the teeth on their nose adapters is made by keying to allow, after wear of the teeth, to proceed with their removal and replacement.
  • the horizontal, lateral, oblique or various stresses inherent to the applications and uses also cause deteriorations in the tooth-nose-adapter relationship, but also on the keying.
  • tooth-adapter fitting configuration as shown figure 1 , in the form of a fitting either pyramidal or frustoconical.
  • the nose of the adapter support has, in its front part, a stabilizing plate and the rear part of the adapter holder comprises housings receiving the two ears of the tooth.
  • the play established in the production of the pieces is such that J2 between the upper and lower faces of the fitting is greater than that achieved at the levels of the stabilizing plate and the ears (J1) .J2> J1.
  • the keying systems of the teeth to ensure their retention on their adapter supports, are arranged, either vertically or horizontally. Their keys are assisted or not by an elastic element. Placed horizontally, they have the disadvantage of difficult access because of the presence too close to neighboring adapters. Placed vertically, they pre-dispose to the loss of keys, especially from the bottom.
  • the first relates to a vertical key formed by two cylinders which screw on one another, one forming a bolt and the other forming a nut ( Figures 5, 6 and 7 ).
  • a rubber tube is placed between the two.
  • the rubber By screwing the two elements forming the key that come together, it tends to crush and expand the rubber tube. It is positioned in a recess provided in the body of the adapter where it can expand, harden under the screwing pressure. This ensures the retention of the key in use.
  • the rubber the position of which is imposed by the recess in the adapter, places the metal elements forming a key in a random position with respect to the orifices of the tooth where they can not systematically find in rear contact position to ensure the retention of the tooth. In addition to this, there is no, practically or very little, in the case of favorable random position of the key, rear support force for the retention of the tooth.
  • the second is placed horizontally ( Figures 8 and 9 ).
  • a rubber tube is introduced into its housing in the adapter.
  • a cylindrical pin forming a key is introduced through one or other of the orifices of the tooth.
  • the diameter of the rod is slightly greater than the inside diameter of the rubber tube to create a clamping to ensure the holding in place of the key during service.
  • sandwich keys as described by the applicant, which are particularly arranged with a particular structure of two components movable relative to each other and between which is disposed an elastically deformable material.
  • Such a key is described in the patent PCT WO 2004/035945 the applicant.
  • This type of key is specific to a configuration of the tooth with a skirt surrounding and protecting the adapter.
  • STICKEY process subject of the patent EP No. 618,334 which provides for the insertion of a key in a vertical plane, the key being tapered from top to bottom, and receiving, in a suitable chamber, the connecting material.
  • This is in the form of a resin which solidifies by forming, after stiffening, a retaining sheath between the tooth and the adapter.
  • the key is completely embedded in the connection volume between the tooth and the adapter. Specific tools are then required to proceed with its removal and / or tearing, see also heating the elastic material to make it liquid and allow the removal of the key.
  • connection tooth-adapter This reflection was also directed to the connection tooth-adapter by the design of a specific keying device responding to the problems posed and goals sought.
  • the applicant's approach has been to propose a tooth-adapter coupling assembly that can implement, independently or in combination, depending on the case and application, special provisions in the contact zones between the tooth and the nose-adapter. on the one hand, and in the introduction of a keying device, on the other hand.
  • the connection between the tooth and the adapter is substantially improved by the addition of complementary contact areas for the absorption of stresses of all kinds and multi-directional.
  • the new design of the keying device also contributes to the limitation of the movement between the tooth and the adapter, while avoiding, as far as it is concerned, all risks of escape, from the top or the bottom, in the nose connection.
  • -adapteur which is perfectly secure by leaving no possibility of inadvertent snap when used in situ.
  • the key is remarkable in that it is constituted by a pyramidal body allowing it to have a wedge effect, and in that the lower zone of the key is arranged to engage in the lower portion forming the seat of the tooth, and in that the key in its intermediate portion has on its lateral faces a plurality of horizontal zones of tool holders extended by alternating recessed areas.
  • the coupling assembly of wear parts on support tools for equipment of public works machines is remarkable in that the tooth and the adapter are arranged with profiled complementary support shapes located between their respective contact and connecting ends, said shapes being arranged symmetrically and in opposition on the upper and lower faces of the nose of the adapter and the tooth, and in that the key is arranged with three specific zones, one intermediate to be engaged and cooperate with the sleeve, another upper opening of the sleeve and being arranged with means for gripping and positioning a disassembly tool, and another lower to engage in the lower part forming seat of the tooth, and in that the key in its intermediate portion has on its lateral faces a plurality of horizontal zones of tool holders extended by an alternation of recessed areas and projections capable of cooperating with a plurality of complementary raised and recessed zones established in the sleeve to ensure an adjustment and anchoring, and in that the tooth is arranged with a flared upper opening allowing the introduction of the key and the positioning and actuation of a tool for
  • a tooth (D) and an adapter (A) can be associated and secured by a key (C).
  • the nose of the adapter is arranged in known manner in front with a stabilizing plate and or not openings for the reception of lateral ears arranged at the ends of the tooth.
  • the tooth and the adapter are arranged with complementary shapes (FA) supporting profiles in differentiated planes located between their respective ends and the stabilizing plate for the adapter and the tooth base, of on the one hand, and their opposite connecting and centering ends, on the other hand.
  • These complementary shapes (FA) are arranged symmetrically and in opposition on the upper (FS) and lower (FI) faces of the nose of the adapter and the tooth.
  • These complementary shapes are therefore additional support zones that complete the support zones installed on the stabilization plates, in front of the nose of the adapter, and back, if necessary, in the ears housing of the tooth, which no longer have to receive the effort alone when applying a stress on the stabilizing plate.
  • These shapes (FA) profiled additional support can increase the surface of stabilizing plates, to perform a better distribution of the forces received by the adapter nose, and to increase the total surface receiving the transmitted forces. This reduces the possibility of movement of the tooth relative to the adapter and reduces wear.
  • the upper (FS) and lower (FI) faces of the adapter nose are arranged between the front part of the stabilizing plate and the rear part beyond the zone constituting the nose of the adapter with staggered shapes established on all or part of the width of the nose.
  • said stepped shapes located on the upper and lower faces of the nose of the adapter are established in the extension of the stabilizing plate, established in a plane (a) which is extended by an inclined plane (a2) until connection with the upper part connecting the area from the nose of the adapter to the body of the adapter.
  • the stepped shape thus defines an upper plane (a3) of complementary support which is oriented angularly with respect to the plane (a) of the stabilizing plate and also with respect to the oblique connection plane (a2).
  • the stepped form is, in its front part, in turn connected to the stabilizing plate (a1), itself offset with respect to the plane (a), by a tilting inclined plane (a4), so that said shape has, in its front part, a sloping configuration forming a notch.
  • the plane (a2) is inclined at the angle (G2) with respect to the plane (a).
  • the plane (a3) which starts from the same vertex (0) as the plane (a2), defines, with the latter, an angulation (G3) smaller than the angulation (G2), which allows the establishment of contact (a4 - a5) forming abutments at an inclination (G4) less than 90 ° with respect to the plane (a1) and oriented relative to the longitudinal axis of the assembly in an inclination (G5) also less than 90 °.
  • the shape (FA) thus described is found on the underside of the nose of the adapter symmetrically and opposite to the longitudinal median axis of the adapter.
  • the width of this shape (FA) on the nose of the adapter is preferably equal to half of the total width of the nose of the adapter thus leaving partially free the inclined plane (a2). It should be noted that the connection zone of the upper inclined plane (a3) with the inclined plane (a2) can be locate at any level relative to the body of the adapter.
  • the particular configuration of the adapter nose, by its additional forms of support, offers a better imbrication of the tooth on the adapter nose.
  • the tooth is thus arranged in a complementary manner to allow the reception of additional forms of the adapter nose.
  • figure 10 upper (LS) and lower (LI) housings disposed from the upper and lower faces of the tooth, and receiving the form (FA) of the aforementioned type. These housings have support walls and contact with the forms (FA).
  • the zone of junction with the front end forming a notch of the shape (FA) can be complementary ( figure 12 ) to define a firm interlocking complementary parts facing, or alternatively, the tooth may present ( figure 14 ) an internal clearance, so that the notch portion is not in contact and contact with the bottom of the housing established on the tooth and receiving complementary shapes (FA).
  • the particular configuration of the nose of the adapter and the tooth greatly increases the contact and support surfaces.
  • the intermediate support zones may be arranged on the horizontal and / or vertical faces of the nose of the adapter, the tooth being arranged in a complementary manner.
  • This implementation thus meets a first objective, that of limiting the respective movements of the tooth on the adapter with increasing bearing surfaces and their angular orientation to find themselves favorably positioned to respond and absorb the multi-directional stresses transmitted by the tooth.
  • this implementation can be sufficient, whatever the keying system used.
  • the keying device uses, to fulfill the functions and objectives sought above recalled, a key C, having a specific profile and conformation, capable of engaging and cooperating in a sheath (F) having an elastic capacity of deformation, the key and the sheath being able to be engaged and protected in the assembly of the tooth (D) on the adapter (A) found on the buckets and buckets of the public works machines.
  • the adapter and the tooth are themselves profiled, one to receive internally said sheath, and the other to, on the one hand, protect the key in partial overflow of the sheath and allow the introduction of tools disassembly of the key in the situation of removal of the worn tooth.
  • the adapter (A) has a housing (AL) for receiving the elastic sleeve (F) ( figure 25 ) and the tooth (D) ( figures 26 , 27 , 28 and 29 ) has an upper orifice (D1) for the introduction of the key (C) with the passages (D1,2) and (D1,3) for the access of the disassembly tool of the key, and a lower orifice (D2) having the stop (D2,1) and the opening portion (D2,2).

  • the rear face in contact with the orifices of the tooth (D) is more advantageously rounded.
  • a boss (C2-C3) having a function of gripping and against-support of the tool, and one or more notches (C4) successive horizontal and spaced along said parts. These notches are intended to allow the positioning of the tip of the tool for removal. At least the top notch that appears figure 19 is disengaged from the sheath (F) and into the space or introduction opening formed in the tooth. The following notch (s) may be partially in the interior volume of the sheath when the key is in place. The release of the key causes the progressive accessibility to the other notches to allow the introduction of the tool again and operate an additional clearance until the final removal of the key.
  • the intermediate portion (Z2) of the key then has, on the two lateral faces whose surface is voluntarily broadly dimensioned and underlying, one or more recessed areas (C5) separated by relief zones (C15) alternately. Said zones (C5-C15) are established in a horizontal plane on said lateral faces. These so-called zones (C5-C15) thus have a complementary profile with a configuration similar to that in the inner part of the sleeve (F) with a succession of complementary hollow and relief zones (F15-F16) to allow assembly and locking in position of the key in the sheath. In view of the constitution of the sheath of a material having an elastic capacity of deformation, it ensures a firm connection of the key in the sheath.
  • the front face (C6) of the key is rectilinear and terminated in the lower zone by a radius or chamfer (C7) to avoid an angle that could damage the area (F1-2) of the elastic sleeve during its introduction.
  • the rear face of the key comprises a zone (C8) recessed with respect to the two active faces (C9) and (C10), arranged in the upper and lower part of the key, which bear in the two orifices (D1) and ( D2) of the tooth (D).
  • the active face (C9) is arranged with a notch (C11) forming a stop for locking the exit of the key upwards and, at the active end face (C10), a chamfer (C12) to facilitate the introduction of the lower end of the key in the hole of the tooth (D2).

  • On the lateral interior faces of the passage (F1) are arranged reliefs (F1-3) in a variable number and corresponding to those established on the faces side of the key and whose shape is conjugated with those of the corresponding recesses (C5) of the key.
  • the inside rear side is marked (F1-4) and is straight. Its mission is to guide the key when it is introduced.
  • the height of the sleeve is set to correspond to the intermediate zone (Z2) of the key with its successive parts (C5-C15) recessed and raised.

  • the adapter has a vertical opening of pyramidal configuration to receive the sheath.
  • the tooth has an upper orifice (D1) for introducing the key with flared parts (D12-D13) to allow the passage of the active part of the disassembly tool and access to the different notches (C4).
  • said flared portions have a straight-sloped profile (D12.1-D13.1) to constitute a base of counter-support during the pivoting movement of the release tool.
  • the lower part of the tooth (D) has an opening of passage (D2) of the lower end of the key with an upper recess zone (D2.1) corresponding to the zone of support of the zone (C13) of the wedge forming a seat, the lower opening part being referenced by (D2.2) and receiving the final end of the key.

After passage, the lateral zones in relief of the sheath return to their initial position and are anchored in the recessed areas of the key. After setting up, we are in the situation of assembly of figure 31 and 32 .
  • a conventional lever forming tool such as a screwdriver which, resting on the faces (D1-2-1) and (D1 -3-1) passages (D1-2) and (D1-3), can lift the key by placing itself in the notches (C4) under the two bosses (C2) and (C3) and in the notches (C4 ) by the effect of counter-support on the straight parts and the tilting of the tool which raises the key.
