  • Ground engaging assemblies generally comprise an adaptor attached to a ground engaging implement such as a bucket, with the adaptor releasably securing an intermediate adaptor or a replaceable tip.
  • the intermediate adaptor will have means to releasably secure a replaceable tip.
  • Such assemblies can be difficult to assemble in the field requiring two or more persons to do the assembly, and it is desirable to improve these assemblies so that they work better in use.
  • such assemblies generally include adaptors having a tapered forward body, which will fit into a tapered blind socket on an intermediate adaptor or replaceable tip.
  • This tapered mating of parts results in a wearing of the tapered surfaces due to relative movement of the assembled parts. Once sufficient wear takes place, the axial forces applied to the system during use can prematurely result in the replaceable tip or the intermediate adaptor being split apart due to a wedge effect which results from the tapered mating of parts.

  • the protrusion 830 is effectively curved in the upward direction away from a central longitudinal axis of the intermediate adaptor 8, forming a hook like formation, due to the concave surface 832 and convex surface 834.
  • the concave surface 832 and convex surface 834 are a substantially constant width apart.
  • a radius is provided between the concave surface 832 and the upper bearing surface 848, which causes the protrusion 830 to thicken at this location.
  • the tip 6 Due to the tip 6 having the convex surface 616 and concave surface 618 forming the recess 614, the tip 6 has to be positioned onto the protrusion 830 by means of a relative rotation action, whereby once in position the tip 6 can be self supported on the intermediate adaptor 8. Once positioned in the location of figure 6, and even until the under surfaces 608 and 808 are in a condition of being approximately 20° below a horizontal orientation, the replaceable tip 6, by virtue of the convex and concave surfaces mating, is not able to be disconnected without relative rotation. This makes the replaceable tip 6 considerably easier to install than prior art tips, in that once in place the insertion of the lock member 900, and its securing can be a one person operation.

  • protrusion 830 and recess 614 when used for example on a replaceable tip 6 and intermediate adaptor 8, is that protrusion 830 is shaped so as to locate and or guide the replaceable tip 6 when tip 6 is axially urged towards the intermediate adaptor 8 during use.
  • the locating or guide function of the protrusion 830 is such that the protrusion 830 helps to ensure that the complementary pairs of bearing surfaces on respective components 6 and 8, will be guided towards each other so as to engage each other.
  • tip 6 and intermediate adaptor 8 are first ready to be assembled, they are preferably sized or have tolerances so as to enable the axial bearing surfaces 846 and 624 to engage first before any other respective bearing surfaces engage.
  • the surface 624 is surrounded by a channel 680 of
  • the channel 680 serves several functions. A first is for casting and strength purposes whereby the radius of the channel 680 assists in removing sharp corners from the casting while at the same time removing sources of stress concentration in the final product. Another function served by the channel 680 is that it is a receptacle or repository for worn off material or debris which wears from one or both of the surfaces 846 and 624. This material or debris will be produced by the peening action of axial loads being applied to the assembly or the relative sliding movement which may occur when horizontal or downwardly or upwardly vertical loads are applied and there results differential sliding movement between the tip 6 and the intermediate adaptor 8.
  • Axial loading applied to the sub-assembly of the tip 6 and intermediate adaptor 8 is that loading which occurs along the longitudinal axis 1, of figure 13, in a direction from left to right of the figure. Whereas, in respect of figures 6 and 13, vertical loading is exerted on the tip 6 either in an upward direction (towards the top of the figures) or a downward direction (towards the bottom of the figures).
  • a combination of axial and downwardly vertical loads are the most frequent or predominant that the tip 6 and intermediate adaptor 8 will experience during normal use. Whereas axial and upward loading will be experienced if reverse loading or back blading operations occur in use.
  • the first mechanism is where the protrusion 830 and recess 614, and side protrusions 612 and recesses 818 have their surfaces 624 & 846, 822 & 642 bearing and transmitting the axial load, whereas the downwardly vertical load causes the tip 6 to be under forces which produce relative rotation or bending about a line across the concave surface 832 (making a portion of the surface 832 and a portion of the convex upper surface 616 of recess 614 act as a fulcrum), which is resisted away from this line or fulcrum by the opposed surfaces 824 and 640 in the recess 818 and the protrusions 612 respectively, thus forming a cantilevering assembly.
  • the second mechanism is where the protrusion 830 and recess 614, and side protrusions 612 and recesses 818 have their surfaces 624 & 846, 822 & 642, together and the opposed surfaces 824 and 640 in the recess 818 and the protrusions 612 respectively, combining to bear and transmit the axial load, because the axial load in some circumstances can, due to the curved nature of the protrusion 830 and recess 614 can cause an amount or degree of rotation or deformation which replicates a downwardly vertical load, even if there is no specific downwardly vertical load applied.
  • This second mechanism can also occur when only a vertically downward load is applied, where due to the curved nature of the protrusion 830 and recess 614 can cause an amount or degree of rotation or deformation which will replicate an axial load, causing the surfaces 624 & 846, 822 & 642, of protrusion 830 and recess 614 together and the opposed surfaces 824 and 640 in the recess 818 and the protrusions 612 respectively together to bear and transmit the load.
  • This load bearing by axial and or cantilevering mechanism assists in the transferral of a greater proportion of the stress away from the locations of interface between the intermediate adaptor 8 and tip 6, to a location more central of the intermediate adaptor 8, where it is better able to resist such stress.
  • the axial bearing surfaces 846 and 624 engage first, with movement of the tip 6 axially relative to the intermediate adaptor 8 being limited until the bearing surfaces 846 and 624 wear. Eventually as surfaces 846 and 624 wear, the rear facing surface 642 of protrusion 612 will engage forward facing surface 820. Simultaneously or as each of these wear over time then the upper and lower bearing faces 626, 628 on the tip 6 will engage upper and lower bearing faces 848 and 850 respectively. Once all surfaces are engaged wear is expected to continue, however, the wear is not exacerbated by wedge type forces which would otherwise tend to force opposed sides of the tip apart.
  • the faces 624 and 846 contact each other first, which allows these faces to be used as datum surfaces for the rest of the tip 6 and intermediate adaptor 8.
  • surfaces 626 & 848 and or surfaces 822 & 642 could contact first with simultaneous or sequential wear occurring eventually causing all the pairs of surfaces 624 & 846, 626 & 848 and 822 & 642 to contact simultaneously.
  • Another reason it is preferred that 624 & 846 contact each other first is to assist in the control of the wear, where it is expected that a ratio of replacement of four to six tips 6 will be replaced to one replacement of the intermediate adaptor 8.
  • a second replaceable tip 6 put onto a worn intermediate adaptor 8 will not have surfaces 624 and 846 contacting first, thus relying on the other surfaces contacting and wearing down before 624 and 846 contact.

  • a similar mounting and inter-engagement relationship can be created between the adaptor 10 and the intermediate adaptor 8, or between an adaptor 10 and a replaceable tip which mounts directly to the adaptor 10 without an intermediate tip.
