Abstract
A wear component for a ground engaging tool includes a longitudinally-extending mounting portion connectable to a mounting assembly of the ground engaging tool. The wear component also includes at least one wear portion connected to the mounting portion. The at least one wear portion forms at least one ground engaging edge. The wear component further includes a plurality of longitudinally-spaced ribs projecting from the at least one wear portion and connecting to the mounting portion. The plurality of ribs are configured to affect a direction of a flow of material passing along the at least one wear portion.
Description
- The present disclosure relates generally to a wear component, and more particularly, to a wear component for a ground engaging tool.
- Machines, for example motor graders, dozers, wheel loaders, and excavators are commonly used in material moving applications. These machines include a ground engaging tool having a cutting edge component configured to contact the material. For example, motor graders are typically used to perform displacement, distribution and leveling of material, such as rock and/or soil. The motor graders may move the ground engaging tool over the ground so that the cutting edge component engages with the rock and/or soil so as to displace, distribute, or level the rock and/or soil.
- During use of the cutting edge component, the material may abrade the cutting edge component, causing it to erode away. Accordingly, the cutting edge component may he removably attached to the ground engaging tool and replaced on a periodic basis. Conventional cutting edge components may be formed as a single plate of constant thickness. Such conventional cutting edge components may be relatively costly to manufacture and relatively difficult to handle due to their weight.
- An alternative cutting edge component is described in U.S. Pat. No. 1,633,057 (the '057 patent) issued to Wold. Specifically, the cutting edge component of the '057 patent includes an upper portion of about one-half thickness as a lower portion. By reducing the thickness of the upper portion, the cutting edge component may require less material and may weigh less than the conventional cutting edge component having a single plate of constant thickness. However, the cutting edge component of the '057 patent may still be relatively costly to manufacture and relatively difficult to handle due to its weight. Also, the cutting edge component may not efficiently direct material, such as rock and/or soil, around the cutting edge component.
- The disclosed system is directed to overcoming one or more of the problems set forth above.
- In one aspect, the present disclosure is directed to a wear component for a ground engaging tool. The wear component includes a longitudinally-extending mounting portion connectable to a mounting assembly of the ground engaging tool. The wear component also includes at least one wear portion connected to the mounting portion. The at least one wear portion forms at least one ground engaging edge. The wear component further includes a plurality of longitudinally-spaced ribs projecting from the at least one wear portion and connecting to the mounting portion. The plurality of ribs are configured to affect a direction of a flow of material passing along the at least one wear portion.
- In another aspect, the present disclosure is directed to a wear component for a ground engaging tool. The wear component includes a mounting portion connectable to a mounting assembly of the ground engaging tool. The wear component also includes at least one wear portion connected to the mounting portion and forming at least one ground engaging edge. The at least one wear portion has a similar thickness along a first direction as the mounting portion and is offset along the first direction from the mounting portion. The wear component also includes at least one rib projecting from the at least one wear portion. The at least one rib is configured to affect a direction of a flow of material passing along the at least one wear portion.
- In another aspect, the present disclosure is directed to a wear component for a ground engaging tool. The wear component includes a mounting portion connectable to a mounting assembly of the ground engaging tool. The wear component also includes a plurality of wear portions spaced along a distal end of the mounting portion and connected to the mounting portion. Each wear portion forms a ground engaging edge. The wear component also includes a plurality of ribs projecting from the plurality of wear portions. The plurality of ribs connect to and extend distally from the mounting portion. Each rib is configured to affect a direction of a flow of material passing by the respective rib.

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
- An exemplary embodiment of a
machine 10 is illustrated inFIG. 1 . Themachine 10 may be, for example, a motor grader, a backhoe loader, an agricultural tractor, a wheel loader, a skid-steer loader, a dozer, an excavator, or any other type of machine known in the art. As a motor grader, themachine 10 may include aframe assembly 12. Theframe assembly 12 may include a pair of front wheels 14 (or other traction devices) and may support anoperator station 16. Theframe assembly 12 may also include one or more compartments 18 for housing a power source (e.g., an engine) and associated cooling components. The power source may be operatively coupled to one or more pairs of rear wheels 20 (or other traction devices) for propulsion of themachine 10. - The
machine 10 may also include one or moreground engaging tools 30. The ground engaging tool(s) 30 may include one or more wear components, such as one or morecutting edge components 40. In the case of a motor grader, as shown inFIG. 1 , theground engaging tool 30 may include a plurality of the cutting edge components 40 (e.g., six cutting edge components). Alternatively, other numbers of cuttingedge components 40 may he provided, such as from one to eight cutting edge components, depending on the application. - In the embodiment of the motor grader shown in
FIG. 1 , theground engaging tool 30 may include a drawbar-circle-moldboard (DCM)assembly 32 with a moldboard assembly 34 (or other mounting assembly) including asupport surface 36. Thecutting edge components 40 may he removably attached to thesupport surface 36. TheDCM assembly 32 may be operatively connected to and supported by theframe assembly 12 or by another portion of themachine 10. TheDCM assembly 32 may control the movement of themoldboard assembly 34 and therefore also the movement of thecutting edge components 40 mounted to thesupport surface 36 of themoldboard assembly 34. TheDCM assembly 32 may also be supported by ahydraulic ram assembly 38 that controls the movement of theDCM assembly 32. As a result, theDCM assembly 32 and/or thehydraulic ram assembly 38 may control one or more of a vertical, horizontal, or pivotal movement of themoldboard assembly 34 and thecutting edge components 40 mounted to thesupport surface 36 of themoldboard assembly 34. Alternatively, different mechanical and/or hydraulic arrangements, e.g., other than theDCM assembly 32 and/orhydraulic ram assembly 38 described above, may be provided to allow for movement of thecutting edge components 40. -
FIGS. 2-4 show an exemplary embodiment of thecutting edge component 40. The term “longitudinal” refers to a dimension generally lengthwise with respect to thecutting edge component 40, as indicated by the arrow A inFIG. 2 . The term “lateral” refers to a dimension generally extending between a proximal end orproximal edge 58 and aground engaging edge 68 of thecutting edge component 40, as indicated by the arrow B inFIG. 2 . Theproximal edge 58 and theground engaging edge 68 may extend generally longitudinally as shown. In an embodiment, the length of thecutting edge component 40 along the longitudinal direction may range from approximately 24 inches to approximately 92 inches, and the length of thecutting edge component 40 along the lateral direction may range from approximately 8 inches to approximately 16 inches. In one embodiment, thecutting edge component 40 may be approximately 48 inches longitudinally and approximately 16 inches laterally. - The terms “distal” and “proximal” are used herein to refer to the relative positions of the components of the exemplary cutting edge components along the lateral dimension. When used herein, “distal” refers to one end of the
cutting edge component 40 in the lateral dimension, e.g., positioned near theground engaging edge 68 of thecutting edge component 40. In contrast, “proximal” refers to the end of thecutting edge component 40 that is opposite the distal end in the lateral dimension, e.g., positioned near theproximal edge 58 of thecutting edge component 40. - While the
cutting edge component 40 shown inFIGS. 2-4 may be positioned substantially at right angles to the normal direction of travel of thecutting edge component 40, as indicated by the arrow C inFIG. 3 , it is to be appreciated that thecutting edge component 40 may be oriented at an angle and/or curved. The terms “front” and “rear” are also used herein to refer to the relative positions of the components of the exemplary cutting edge components. When used herein, “front” refers to one side of thecutting edge component 40, e.g., positioned near the forward side of thecutting edge component 40 with respect to the direction of travel of themachine 10. In contrast, “rear” refers to the side of thecutting edge component 40 that is opposite the front side. The rear side of thecutting edge component 40 may be the side that is connected to or proximal to thesupport surface 36 of theground engaging tool 30 to which thecutting edge component 40 is mounted. - The
cutting edge component 40 may be replaceable to help ensure productivity and/or efficiency of themachine 10. For example, thecutting edge component 40 may be removably connected to thesupport surface 36 of theground engaging tool 30 by way of one or more fasteners (not shown), such as bolts, inserted through one or more mountingholes 42 in thecutting edge component 40. - The
cutting edge component 40 may include one or more mountingportions 50, which may include the mountingholes 42, connected to one ormore wear portions 60. Thecutting edge component 40 shown inFIGS. 2-4 includes one mountingportion 50 including theproximal edge 58 of thecutting edge component 40 and onewear portion 60 including theground engaging edge 68 of thecutting edge component 40. - The mounting
portion 50 may include a longitudinally-extending substantiallyplanar portion 52 including arear surface 54, afront surface 56, and theproximal edge 58. As shown inFIG. 3 , therear surface 54 and thefront surface 56 may be substantially flat, and the substantiallyplanar portion 52 may taper toward the proximal end of thecutting edge component 40 to form theproximal edge 58. The substantiallyplanar portion 52 may be connectable to themoldboard assembly 34. For example, the substantiallyplanar portion 52 may include the mountingholes 42 for receiving the fasteners (not shown) for attaching thecutting edge component 40 to thesupport surface 36 of themoldboard assembly 34. As shown inFIG. 3 , therear surface 54 may be configured to contact and abut thesupport surface 36. - The
wear portion 60 may include a longitudinally-extending substantiallyplanar portion 62 including arear surface 64, afront surface 66, and theground engaging edge 68. Therear surface 64 and thefront surface 66 may be substantially flat, and the substantiallyplanar portion 62 may taper toward the distal end of thecutting edge component 40 to form theground engaging edge 68. Alternatively, instead of being substantially flat, the substantiallyplanar portion 52 of the mountingportion 50 and/or the substantiallyplanar portion 62 of thewear portion 60 may be substantially curved or may have another type of profile. Also, as shown inFIG. 3 , the substantiallyplanar portion 52 of the mountingportion 50 and the substantiallyplanar portion 62 of thewear portion 60 may have a similar and constant thickness T1 (e.g., between therear surface 54 and thefront surface 56, and between therear surface 64 and the front surface 66) substantially throughout the entire substantiallyplanar portion 52 and the entire substantially planar portion 62 (e.g., except theproximal edge 58, theground engaging edge 68, the mountingholes 42, and/or any beveled edges). In an embodiment, the minimum of the thickness T1 may range from approximately 10 millimeters to approximately 80 millimeters, e.g., approximately 35 millimeters in one embodiment. Alternatively, the substantiallyplanar portion 52. of the mountingportion 50 and/or the substantiallyplanar portion 62 of thewear portion 60 may have a variable thickness, depending on the application. In an embodiment in which the substantiallyplanar portion 52 and/or the substantiallyplanar portion 62 of have a variable thickness, the thickness of the substantiallyplanar portion 52 of the mountingportion 50 may not exceed the thickness of the substantiallyplanar portion 62 of thewear portion 60. - The mounting
portion 50 and thewear portion 60 may be positioned to from a generally S-shaped profile, as shown inFIG. 3 .

Also, the maximum of the thickness T3 of eachtooth 260 may be larger than the maximum of the thickness T2 of the mountingportion 250, and an average of the thickness T3 of eachtooth 260 may he larger than an average of the thickness T2 of the mountingportion 250. in an embodiment, the thickness T2 of the substantiallyplanar portion 52 of the mountingportion 250 may not exceed the thickness T3 of the substantiallyplanar portion 62 of theteeth 260. The thickness T2 and/or the thickness T3 may vary within different ranges between approximately 10 millimeters to approximately 80 millimeters, depending on the application.

Thus, the middle portion of thecutting edge component 340 in the lateral direction may be thicker than theproximal edge 58 and theground engaging edge 68. Also, the maximum of the thickness T5 of thewear portion 360 may be larger than the maximum of the thickness T4 of the mountingportion 350, and an average of the thickness T5 of thewear portion 360 may be larger than an average of the thickness T4 of the mountingportion 350. In an embodiment, the thickness T4 of the substantiallyplanar portion 52 of the mountingportion 350 may not exceed the thickness T5 of the substantiallyplanar portion 62 of thewear portion 360. The thickness T4 and/or the thickness T5 may vary within different ranges between approximately 10 millimeters to approximately 80 millimeters, depending on the application. In an embodiment, the minimum of the thickness T4 may be at least approximately 35 millimeters, e.g., to maintain structural integrity and a minimum of the thickness T5 may be at least approximately 60 millimeters, e.g., to provide a relatively longer wear life. - Further, at least a portion of the thickness T4 of the mounting
portion 350 may extend both rearwardly and forwardly with respect to the location of theproximal edge 58 as the mountingportion 350 becomes thicker toward its distal end.

sides 394 of thegrooves 390 may formedges 396 with thefront surface 66 of the substantiallyplanar portion 62 of thewear portion 360. Theedges 396 may serve as self-sharpening teeth as wear progresses on thewear portion 360. For example, thewear portion 360 may wear from the bottom (e.g., starting at the ground engaging edge 68) and then upward (proximally). As thewear portion 360 wears away proximally, unworn and sharpened portions of theedges 396 become exposed, and therefore theedges 396 may be self-sharpening. - The
grooves 390 may include a coating of abrasion resistant material. For example, thebottom surface 392, thesides 394, and/or theedges 396 of thegrooves 390 may be coated with the abrasion resistant material. The abrasion resistant material may include a carbide (e.g., tungsten carbide, titanium carbide, and/or chromium carbide) and/or a metal oxide (e.g., aluminum oxide and/or chromium oxide). The abrasion resistant material, e.g., in particle form, may be applied to thegrooves 390 by welding, plasma transfer are deposition, and/or laser deposition. In the exemplary embodiment shown inFIG. 14 , the coating may not fill in thegrooves 390, thereby allowing thegrooves 390 to maintain the profile of thebottom surface 392,sides 394, edges 396, and depth D1. Alternatively, the coating may fill thegrooves 390. -

Also, as shown inFIG. 16 , therear surface 64 of theteeth 460 may include beveled edges. - In addition, the
teeth 460 may taper toward therear surface 64, as shown inFIG. 18 . The side surfaces of the teeth 460 (extending between therear surface 64 and the front surface 66) may be at an angle ranging from approximately 0 degrees to approximately 15 degrees relative to a plane that is perpendicular to thefront surface 66.
