Definitions
- the invention relates to the technical sector of load handling equipment including public works machinery with buckets, buckets or other means likely to come scrape, remove, move materials and others for their evacuation from a place given to other operating stations using said machines.
- connection is in the majority of cases carried out by a keying, the tooth or the shield and the support-adapter being profiled for the reception of the key.
- This may be metallic with an exclusive mechanical assembly or with the integration of a support element of elastic material which can also be in the form of a sleeve previously shaped or made in situ by casting resin.
- Another object of the invention was to provide a device that does not require geometric rigor relative position of the tooth relative to the adapter.
- the connecting device between a wear part and its support used on material handling equipment for public works machinery of the type including the fitting of a tooth on an adapter, and their connection with a sheath of elastically deformable material and a key, the tooth and
- the adapter and in that said key has an end portion said key foot and a key head on either side of a body, and in that the body is inserted into said sleeve while the head keyway is overflowing thereof, and in that the keyway is arranged with an eccentric bearing portion capable of providing a bearing function and thrust against a complementary shape established in a first hole of the tooth , and in that the end of the key head can be actuated in rotation by an operating means, and in that the keyway comprises anchoring means that can temporarily penetrate the elastically deformable sleeve in a first action at a preset value, and in that the end of the keyway is arranged with a conical portion to abut against a second orifice of the tooth, in the context of a squeezing action.
- the solution implemented by the invention to meet the initial objectives reveals unexpected advantages and more particularly the possibility offered to the operator to be able to adjust the position of the key according to the needs in situ according to anchoring forces, pre-set thrust and pushback to desired values. This solution is particularly interesting because it optimizes the fixing and binding according to the environmental constraints during the lifetime of each tooth.

- the connecting device between the tooth (D) and the adapter support (A) implements a particular configuration of the key referenced as a whole by (C) in a sleeve (F) elastically deformable and also configured specific way and in combination with particular arrangements of the tooth and the adapter and this to ensure a specific function.
- This function is to allow the orientation of the key at will in the sleeve in the axial direction and in rotation.
- the sheath is thus partially compressed and restores a flexible reaction force which determines that of the retention of the tooth and which in a service situation, secures the key (C) from the risk of accidental exit while maintaining it in the angular position. chosen.
- the key which is inserted axially into the sheath along a determined axial line is then angularly oriented to come partially anchored in the sheath, and have tight contact with one or both of the orifices of the tooth and with that of the adapter, and this according to the clamping forces made and the misalignment rotation amplitude of the key at the appropriate connection locations.
- This keying can be implemented in a vertical or horizontal position, the latter position being illustrated in the figures of the drawings. To perform the above functions, the components are described.
- Key (Cl) rigid, monolithic, cylindrical, comprises a body (1) of elongated shape with a lower end zone called key foot (C2) including a frustoconical end portion (C3) and a zone (C6) configured with an arrangement of recessed shapes and reliefs to give an ability to anchor the key in the sheath.
- this zone (C6) has one or more grooves or grooves whose depth decreases as it moves away from the end key foot. These coaxial grooves can be supplemented on the periphery by in-ground zones (C6.1) to form notches, as will be specified later.
- the key (C) has at its other end (C4) constituting the key head a cylindrical portion (C5) offset greater diameter than the body (Cl).
- This offset is as shown in Figures 3, 4 is partially tangential to the body (Cl) and the opposite of this overflow portion to form eccentricity.
- the key has a raised area (C7) with one or more notches (C8) for taking a disassembly tool.
- the key has a face (C9) connecting the body (Cl) and the offset (C5).
- the head of the key can be arranged with any form for receiving an operating tool to control the rotation of the key in the operating conditions developed below.
- the sleeve (F) receiving the key (2) is made of a material having an elastic capacity of deformation.
- This sleeve of frustoconical outer shape (Fl) is of great length but less than that of the section of the nose of the adapter in which it is housed. Internally, it has a central hole (F2) whose diameter is equal to that of the body (Cl) of the key.
- Its thickness is variable depending on the position of misalignment that will be able to take the key (C) in situation of service. This thickness is maximum in the receiving zone of the keyway (C2) whose angular displacement will be greater during the misalignment.
- the sleeve implemented according to the invention is of a simplified configuration.
- the adapter (A), shown in FIGS. 8 and 9, has a first transverse housing opening (A2) of frustoconical configuration for the oriented reception of the sheath of complementary configuration.
- the transverse housing (A2) allows the reception of the sleeve being thus established on only part of the width of the receiving zone of the adapter.
- This transverse housing thus has a bottom abutment face of the sheath. It is extended by a second hole or hole (A3) complementary overflowing into the external lateral clearance (A4) of the adapter.
- the diameter of the hole (A3) is voluntarily larger than that of the body of the key (Cl) to avoid premature contact with the key during its first phases of misalignment.
- the sheath is introduced by the opposite lateral clearance (A5).
- the offset between the hole (A3) and the bottom of the housing (A2) of the sheath (F) forms the shoulder (A7).
- the tooth (D) shown in FIGS. 10 and 11 comprises two orifices (D2) and (D3) formed in the vertical or horizontal walls according to the configuration of the tooth, and as represented in the drawings by way of example in the lateral ears (D4) (D5).
- the orifice (D3) receives the head (C4) of the key.
- the size of this orifice is chosen in a particular manner and is greater than the diameter of the body (Cl) of the key. More specifically, and in an advantageous implementation, the diameter of the orifice (D3) is obtained by adding to the value of the diameter (C1) of the key, twice the difference between the value of the diameters (C5) and ( Cl) of the key.
- the orifice (D2) receives the end (C3) of the keyway with a dimension substantially greater than the latter so as not to create an undesired contact during certain misalignments of the key.
- connection device it is therefore necessary to describe the mounting and operation of the connection device in service. It is previously specified that the assembly of the tooth and the adapter, depending on their fitting geometry may have variable relative positions with respect to each other and the connecting device according to the invention, and in particular the key which is rotatable at will in the axial direction and in rotation, can be in a plurality of positions. These positions are hereinafter set forth and are identified in the figures of the drawings (FIGS. 15 to 18.1) in which they are presented in six phases in which each performs the same function.
- PHASE 1 This corresponds to the assembly of the various elements and represents the rest position, represented in FIGS. 15, 15.1.
- the sheath (F) is inserted and positioned in the housing (A2) of the adapter.
- the key (C) is introduced through the orifice (D3) by being manually pushed into the bore (F2) of the sheath.
- the key in this phase has no contact with either the tooth or the adapter.
- the key head (C4) and in particular the offset portion (C5) is oriented to take place in the orifice (D3) of the tooth.
- the axis DD of the orifices (D2-D3) of the tooth is different from the axis AFC-common to the adapter, the sheath and the key.
- the two axes DD and AFC are initially parallel, with a difference according to a variable value E which can be zero so fortuitously depending on the geometry of the fitting considered, they are to be confused.
- E which can be zero so fortuitously depending on the geometry of the fitting considered, they are to be confused.
- the complete depression of the key in the sheath is obtained when its face (C9) abuts on the face (A6) opposite the adapter
- PHASE 2 This corresponds to a first method of fixing and clamping the tooth with a representation in FIGS. 16 - 16.1.
- the key head by its offset (C5) forcing the semi-circumferential surface (D3.1) on the first contact zone (P) with the lateral orifice formed on the tooth receives a reaction force (FlC ) which moves the body (Cl) forwards by compressing the sheath (F) according to the arrow (F2C) which, by resisting this compression forces the opposite part to the keyway to tilt in opposite directions and submit to the sheath a identified constraint (F3C). Due to its elastically deformable constituent material, the sheath (F) is susceptible to deformation at the contact areas considered. Thus the zone (C6) by its particular configuration with projecting and recessed parts, illustrated for example by grooves and projections (C6.1) will become embedded in the sheath and form an anchorage in the angular position chosen by maintaining the key.
- zone (C6) by its particular configuration with projecting and recessed parts, illustrated for example by grooves and projections (C6.1) will become embedded in the sheath and form an anchorage in the angular
- the key and more particularly the key body behaves as a lever arm partially blocked in the sheath. Furthermore, the key body transmits from its portion (C5) at the point (P) a force adjustable on the face (D3.1) for the retention of the tooth.
- the key misaligned with respect to its initial position has changed direction orientation according to the angle GlDR, and that of its rotation according to the angle GIRT.
- the positioning illustrated and described in FIGS. 16, 16.1 corresponds to the use of the coupling assembly for the purposes of normal earthworks.
- PHASE 3 This corresponds to a second level of attachment and tightening of the tooth.
- PHASE 6 This is the dismantling of the key. After cleaning if necessary of the opening D3 of the tooth giving access to the key head and its projecting portion (C7), rotation reversal is performed to eliminate the support stresses given by the offset part (C5). in the hole (D3). We cancel the compression on the sheath.
- the key returns to its rest position shown in FIG. 15 and simply by pushing on the end portion (C3) through the orifice (D2) or by the action of a screwdriver in the notch C8 of the tooth, it is possible to remove the key.
- the new solution of the invention therefore perfectly meets the desired objectives.
- it provides a permanent possibility of adjusting the pressure exerted by the key in its connection mode adapted to the nature of the work performed and their operating conditions.
- the solution according to the invention provides an unexpected advantage with this ability to adjust the anchoring pressure of the key on the entire coupling according to the needs in situ.
