Abstract
A wear component assembly for use with a material handling implement can include an adapter configured for attachment to a lip of the material handling implement, the adapter having a forward-projecting nose, and a wear component including a pocket configured to receive the nose therein, the pocket having a deepest internal surface, and the surface being longitudinally spaced apart from a forward end of the nose. Another wear component assembly can include an adapter and a wear component, and in which contact between an inclined surface formed on the nose and an inclined surface formed in the pocket prevents contact between a deepest pocket surface and a forward end of the nose. A material handling implement can include a wear component including a pocket that receives an adapter nose therein, the pocket having a deepest internal surface longitudinally spaced apart from a forward end of the nose.
Description
- This disclosure relates generally to mining, excavation and other material handling equipment and, in an example described below, more particularly provides for stabilization of a wear component on an implement.
- Material handling implements (such as buckets, shovels and other types of excavation and mining implements) are frequently provided with replaceable wear components. For example, wear components can be used to protect a forward material-engaging lip of a material handling implement, in order to prevent or delay repair or replacement of the lip, and to achieve other purposes (such as, to enhance the effectiveness of the implement in engaging or breaking up the material).
- The wear components are subjected to a variety of different loads from various directions during material handling operations. In general, the more a wear component is allowed to deflect in response to those loads, the more rapid and greater will be the wear of the wear component, and the sooner the wear component will need to be replaced. Replacement of wear components can be costly and time-consuming.
- It will, therefore, be appreciated that improvements are continually needed in the art of securing wear components on material handling implements. Such improvements are provided to the art by the present disclosure, and these improvements can be realized in a wide variety of different configurations.

FIG. 1 is animplement 10 for a material handling apparatus which can embody principles of this disclosure. However, it should be clearly understood that theimplement 10 is merely one example of an application of the principles of this disclosure in practice, and a wide variety of other examples are possible. Therefore, the scope of this disclosure is not limited at all to the details of theimplement 10 described herein and/or depicted in the drawings. - In the example of
FIG. 1 , theimplement 10 is of the type known as a “dipper” or “bucket” of a cable shovel, but it should be clearly understood that the principles of this disclosure can be utilized with other types of mining, excavation (or other material handling) implements. In the illustration ofFIG. 1 , theimplement 10 is rotated so that a bottom material-engaging side of the implement is clearly visible. From this perspective, it may be seen thatmultiple teeth 12 are mounted on theimplement 10 for piercing the earth or other material. - The
teeth 12 are typically rapidly worn down or otherwise damaged during use of theimplement 10, and so the teeth are replaced periodically or when excessive wear is evident. Specially configuredadapters 14 releasably secure theteeth 12 to a forward edge of alip 16 of theimplement 10 in this example. In other examples, theteeth 12 may be secured directly to thelip 16. - The
teeth 12 andadapter 14 are merely examples of wear components that can be securely and conveniently attached to a material handling implement using the principles of this disclosure. Other examples of wear components includeshrouds lip 16 and sides of theimplement 10. Thus, the scope of this disclosure is not limited to use of any particular types of wear components. - As used herein, the term “forward” is used to indicate a direction in which the
implement 10 displaces to engage a material. Thus, a forward edge of thelip 16 would first engage the material, if the forward edge were not protected by theteeth 12,adapter 14 andshrouds FIG. 1 example, a rearward direction would be toward a back of theimplement 10 from the forward edge of thelip 16. - Referring additionally now to
FIGS. 2 & 3 , top and side views of an example of anadapter 14 that may be used with theFIG. 1 material handling implement 10 is representatively illustrated. Theadapter 14 is described below as it may be used with theFIG. 1 material handling implement 10, but it should be understood that the scope of this disclosure is not limited to use of theadapter 14 with any particular type of material handling implement. - The
adapter 14 as depicted inFIGS. 2 & 3 includes upper andlower legs lip 16 of theimplement 10. In this example, thelip 16 would be received in arecess 26 formed between thelegs adapter 14 could be attached to thelip 16 by other means (such as, using fasteners, connectors, wedges, etc.). - A
nose 28 projects forward from abody 30 of theadapter 14. In this example, thenose 28 is angled downward somewhat (e.g., alongitudinal axis 32 of the nose is inclined downward in the forward direction relative to thelegs 22, 24). In other examples, thenose 28 may be angled upward or parallel relative to thebody 30 orlegs - A forward end of the
nose 28 is defined by aplanar surface 34. In this example, thesurface 34 is oriented orthogonal to thelongitudinal axis 32 of thenose 28. In other examples, thesurface 34 may not be planar (e.g., the surface could be curved), and may not be orthogonal to theaxis 32. Thus, it will be appreciated that the scope of this disclosure is not limited to any particular shape or orientation of any of the physical features of thenose 28 as described herein or depicted in the drawings. - The
end surface 34 is encircled by fourinclined surfaces 36. Thesurfaces 36 are inclined inward (toward the axis 32) in a forward direction. An included angle a is formed between the side surfaces 36 (seeFIG. 2 ), and an included angle b is formed between the upper and lower surfaces 36 (seeFIG. 3 ). The angles a, b may be different, or they may be the same, in different examples. - Although four of the
inclined surfaces 36 are depicted in theFIGS. 2 & 3 example, any other number of surfaces may be used in other examples. If only asingle surface 36 is used, then thesurface 36 can have a frusta-conical shape. - An
opening 38 is formed laterally through thenose 28 for receiving a connector or fastener therein, in order to mount a wear component onto the nose. As described more fully below, atooth 12 is attached to theadapter 14. However, the scope of this disclosure is not limited to use of any particular type of wear component with theadapter 14. - Referring additionally now to
FIGS. 4 & 5 , respective horizontal and vertical cross-sectional views of an example of atooth 12 that may be used with theadapter 14 ofFIGS. 2 & 3 are representatively illustrated. TheFIGS. 4 & 5 tooth 12 may be used with other adapters, or may be attached directly to a lip of an implement, in keeping with the scope of this disclosure. - For convenience, the
tooth 12 is described below as it may be used with theFIGS. 2 & 3 adapter 14.Openings 48 are formed inside walls 50 of thetooth 12 to receive a connector or fastener to attach the tooth to theadapter 14. - As depicted in
FIGS. 4 & 5 , thetooth 12 has aforward end 40 configured to pierce, penetrate or break up material engaged by a lip of an implement on which the tooth is mounted via theadapter 14. In this example, the forward end is curved upward in the forward direction and has a broad scoop shape. However, the scope of this disclosure is not limited to any particular type or shape of the tooth forwardend 40. - An internal recess or
pocket 42 is formed in arearward end 44 of thetooth 12. Thepocket 42 extends forward from therearward end 44 and terminates at adeepest surface 46 in the tooth 12 (farthest from the rearward end). - Inclined
surfaces 52 encircle thedeepest surface 46. Thesurfaces 52 are complementarily shaped relative to theinclined surfaces 36 on thenose 28. Thus, in this example, the included angle a is formed between the side surfaces 52 (seeFIG. 4 ) and the included angle b is formed between the upper and lower surfaces 52 (seeFIG. 5 ). If only asingle surface 52 is used, then the angles a, b can be the same. - Referring additionally now to
FIGS. 6 & 7 , respective horizontal and vertical cross-sectional views of a portion of awear component assembly 54 comprising thetooth 12 positioned on theadapter 14 are representatively illustrated. As viewed inFIGS. 6 & 7 , thenose 28 is fully received in thepocket 42, so that a fastener or connector can be installed in the alignedopenings tooth 12 to theadapter 14. - Note that the
inclined surfaces 36 on thenose 28 are in contact with theinclined surfaces 52 formed in thetooth 12. In this manner, loads due to forward penetration of thetooth 12 into the earth or another material will be reacted at these engagedsurfaces surfaces tooth 12 relative to thelongitudinal axis 32 of thenose 28. The contact between thesurfaces axis 32. - Note, also, that there is a gap G between the
end surface 34 of thenose 28 and thedeepest surface 46 of thepocket 42 in thetooth 12. This gap G ensures that thenose 28 does not “bottom out” in thepocket 42, and that thesurfaces tooth 12 andadapter 14 wear during use. - It may now be fully appreciated that the above disclosure provides significant advancements to the art of securing wear components on material handling implements. In the examples described above, the
tooth 12 is attached to theadapter 14 in a manner that stabilizes the tooth on the adapter, due to contact between theinclined surfaces - The above disclosure provides to the art a
wear component assembly 54 for use with a material handling implement 10. In one example, thewear component assembly 54 comprises: anadapter 14 configured for attachment to alip 16 of the material handling implement 10, theadapter 14 having a forward-projectingnose 28; and awear component 12 including apocket 42 configured to receive thenose 28 therein, thepocket 42 having a deepest internalfirst surface 46, and thefirst surface 46 being longitudinally spaced apart from a forward end of thenose 28. - The forward end of the
nose 28 may be encircled by at least one inclinedsecond surface 36. Thefirst surface 46 may be encircled by at least one inclined internalthird surface 52 of thepocket 42. The inclinedsecond surface 36 may contact the inclinedthird surface 52. - The
second surface 36 may contact thethird surface 52 while thefirst surface 46 is longitudinally spaced apart from the forward end of thenose 28. The forward end of thenose 28 may comprise a planarfourth surface 34 that is orthogonal to alongitudinal axis 32 of thenose 28. - The
second surface 36 may be inclined relative to thelongitudinal axis 32. Thethird surface 52 may be inclined relative to thelongitudinal axis 32. - Contact between at least one inclined
second surface 36 formed on thenose 28 and at least one internal inclinedthird surface 52 formed in thepocket 42 may prevent contact between thefirst surface 46 and the forward end of thenose 28. - Also provided to the art by the above disclosure is a
wear component assembly 54 that comprises: anadapter 14 configured for attachment to alip 16 of a material handling implement 10, theadapter 14 having a forward-projectingnose 28; and awear component 12 including apocket 42 configured to receive thenose 28 therein, thepocket 42 having a deepest internalfirst surface 46. Contact between at least one inclinedsecond surface 36 formed on thenose 28 and at least one internal inclinedthird surface 52 formed in thepocket 42 prevents contact between thefirst surface 46 and a forward end of thenose 28. - The forward end of the
nose 28 may be encircled by thesecond surface 36, and thefirst surface 46 may be encircled by thethird surface 52 of thepocket 42. Thesecond surface 36 may contact thethird surface 52 while thefirst surface 46 is longitudinally spaced apart from the forward end of thenose 28. The forward end of thenose 28 may comprise a planarfourth surface 34 that is orthogonal to alongitudinal axis 32 of thenose 28. - A material handling implement 10 is also described above. In one example, the implement 10 can comprise: a
lip 16; anadapter 14 attached to thelip 16, theadapter 14 having a forward-projectingnose 28; and awear component 12 including apocket 42 that receives thenose 28 therein. Thepocket 42 has a deepest internalfirst surface 46, and thefirst surface 46 is longitudinally spaced apart from a forward end of thenose 28. - The forward end of the
nose 28 may be encircled by at least one inclinedsecond surface 36, thefirst surface 46 may be encircled by at least one inclined internalthird surface 52 of thepocket 42, and the inclinedsecond surface 36 may contact the inclinedthird surface 52. Thesecond surface 36 may contact thethird surface 52 while thefirst surface 46 is longitudinally spaced apart from the forward end of thenose 28. The forward end of thenose 28 may comprise a planarfourth surface 34 that is orthogonal to alongitudinal axis 32 of thenose 28. - Contact between at least one inclined
second surface 36 formed on thenose 28 and at least one internal inclinedthird surface 52 formed in thepocket 42 prevents contact between thefirst surface 46 and the forward end of thenose 28. - Although various examples have been described above, with each example having certain features, it should be understood that it is not necessary for a particular feature of one example to be used exclusively with that example. Instead, any of the features described above and/or depicted in the drawings can be combined with any of the examples, in addition to or in substitution for any of the other features of those examples. One example's features are not mutually exclusive to another example's features. Instead, the scope of this disclosure encompasses any combination of any of the features.
- Although each example described above includes a certain combination of features, it should be understood that it is not necessary for all features of an example to be used. Instead, any of the features described above can be used, without any other particular feature or features also being used.
- It should be understood that the various embodiments described herein may be utilized in various orientations, such as inclined, inverted, horizontal, vertical, etc., and in various configurations, without departing from the principles of this disclosure. The embodiments are described merely as examples of useful applications of the principles of the disclosure, which is not limited to any specific details of these embodiments.
- The terms “including,” “includes,” “comprising,” “comprises,” and similar terms are used in a non-limiting sense in this specification. For example, if a system, method, apparatus, device, etc., is described as “including” a certain feature or element, the system, method, apparatus, device, etc., can include that feature or element, and can also include other features or elements. Similarly, the term “comprises” is considered to mean “comprises, but is not limited to.”
- Of course, a person skilled in the art would, upon a careful consideration of the above description of representative embodiments of the disclosure, readily appreciate that many modifications, additions, substitutions, deletions, and other changes may be made to the specific embodiments, and such changes are contemplated by the principles of this disclosure. For example, structures disclosed as being separately formed can, in other examples, be integrally formed and vice versa. Accordingly, the foregoing detailed description is to be clearly understood as being given by way of illustration and example only, the spirit and scope of the invention being limited solely by the appended claims and their equivalents.
