Definitions
- This invention relates in general to a system for attaching a replaceable ground engaging wear member, and more particularly to a compactor tooth for use on a compactor wheel.
- a compactor is a type of self-propelled work machine used at construction sites to compact fill dirt and at landfills to crush and compact waste and refuse materials. In landfill applications, the compaction of such materials reduces the size and bulk of the materials, which are then covered by a layer of soil.
- Compactors have wheels with large steel drums or rollers. The cylindrical exterior surfaces of such drums are commonly ringed with a large number of teeth to increase the compaction and crushing capability of the compactor. Because such teeth are subject to wear, it is desirable to construct such teeth with replaceable tips or wear members, which are detachably mounted to an adapter or mounting block that is welded to the compactor wheel drum. In the past, steel pins and other types of retaining devices have been employed to detachably secure the tips to the mounting blocks.

- two of the retainers 20 may be employed in retaining the tip 18 , one in either side of tooth 10 .
- prior compactor teeth enabled rim pull forces acting on the teeth to be exerted on the retaining pins, causing such pins to break.
- the primary load transmitting surface employed on the replaceable tip of prior designs and the mating load carrying surface on the mounting base of such teeth are disposed at too great of an angle relative to the direction of the rim pull forces acting on the tooth.
- a component of the rim pull force acting in an upward radial direction is created.
- This radial component force tends to rotate the tip about and lift the tip away from its mounting base.
- the opposite lower edge of such prior tips contact the compactor wheel when such rim forces are applied. This creates a pivot point about which the tip rotates relative to the mounting base.
- the compactor tooth 10 of the present invention has a construction especially adapted for transferring rim pull forces exerted on the tip 18 into the mounting block 16 in a manner so as to isolate the transmission of such forces from the retainer 20 , thus reducing the breakage of such retainer 20 .
- the construction of the present retainer 20 and its containment in the tooth maximizes its load carrying capabilities, while at the same time relieving such retainer from experiencing the high loads exerted on the pins of prior compactor teeth devices.
- the circumferentially spaced sides 34 , 36 of the mounting block 16 and the corresponding circumferentially spaced sides 80 , 82 of the tip 18 provide the primary load transferring surfaces for transferring rim pull forces between the tip 18 and mounting block 16 .
- Such surfaces are oriented substantially perpendicular to such rim pull forces acting in the direction of arrow 77 .
- the mounting end 74 of the tip 18 is constructed so as not to contact the cylindrical exterior surface 12 of the wheel 14 when the tip 18 is mounted upon the mounting block 16 . This prevents the edge of the tip 18 from acting as a fulcrum that is located at the greatest distance possible from the retainer 20 . In the present structure, such fulcrum is located, if at all, along one of the circumferentially spaced side surfaces 34 , 36 , which are much closer to the retainer 20 . Thus, and resulting pivotal movement of the tip at the retainer 20 is reduced as compared to prior compactor teeth.
- Retainer breakage is also reduced by the fact that the loads exerted on the retainer 20 are exerted on the generally cylindrical head portion 116 of the fastening member 110 through the hole 100 in the tip 18 on one side and exerted on the barrel member 112 through the concave surface 68 of the tongue portion 56 of the mounting block 16 on the other side.

- This invention relates in general to a system for attaching a replaceable ground engaging wear member, and more particularly to a compactor tooth for use on a compactor wheel.
- 2. Background
- A compactor is a type of self-propelled work machine used at construction sites to compact fill dirt and at landfills to crush and compact waste and refuse materials. In landfill applications, the compaction of such materials reduces the size and bulk of the materials, which are then covered by a layer of soil. Compactors have wheels with large steel drums or rollers. The cylindrical exterior surfaces of such drums are commonly ringed with a large number of teeth to increase the compaction and crushing capability of the compactor. Because such teeth are subject to wear, it is desirable to construct such teeth with replaceable tips or wear members, which are detachably mounted to an adapter or mounting block that is welded to the compactor wheel drum. In the past, steel pins and other types of retaining devices have been employed to detachably secure the tips to the mounting blocks. Statutory Invention Registration No. H946 for Tip And Adaptor Assembly, published Aug. 6, 1991 to Alan H. Lonn, discloses a replaceable tip that is pinned to an adapter by the insertion of a pin through aligned apertures in both components.
- Such pins, however, have been subject to frequent breakage due to loads being exerted on the retaining pin during operation of the compactor. Such pin breakage results in the loss of the tip and damage to the adapter.

FIG. 1 , there is illustrated an assembledcompactor tooth 10 for use on a landfill-compactor wheel 14 of a compactor work machine (not shown). While only onesuch tooth 10 is shown, it should be understood that a large number ofsuch teeth 10 are distributed about the cylindricalexterior surface 12 of thecompactor wheel 14. Eachcompactor tooth 10 includes amounting block 16 and areplaceable wear tip 18, which is selectively retained on the mounting block by aretainer 20. The cylindricalexterior surface 12 is that of asteel drum 22 that is typically used for compactor wheels of compactors, or machines employed for compacting earth in road-building or other types of construction, or for compacting refuse in landfills or the like. The cylindricalexterior surface 12 of thedrum 22 is disposed about acentral axis 24 of thewheel 14. For directional orientation purposes herein, thetooth 10 inFIG. 1 is shown with ‘x’, ‘y’ and ‘z’ axii, with the ‘x’ axis extending in a direction which is generally tangential to the circumference of the cylindricalexterior surface 12 of the wheel, the ‘y’ axis extending in a direction which is generally perpendicular to thecentral axis 24 of thewheel 14, and the ‘z’ axis extending in a direction which is generally parallel to thecentral axis 24. Accordingly, a reference to an axial direction herein means in a direction generally parallel to the ‘z’ axis, a reference to a circumferential direction means in a direction generally parallel to the ‘x’ axis, and a reference to a radial direction means in a direction generally parallel to the ‘y’ axis. - As depicted in
FIGS. 2-4 , themounting block 16 has anarcuate mounting surface 26 for mating contact with cylindricalexterior surface 12 of thecompactor wheel 14. Themounting block 16 is secured to the cylindricalexterior surface 12 of thewheel 14 by welding along chamfered edge surfaces at 28,30. Themounting block 16 has atop surface 32 remote from the cylindricalexterior surface 12, a pair of circumferentially spacedsides sides sides exterior surface 12 of thewheel 14. - In one embodiment, at least one of the axially spaced
sides 38 of themounting block 16 has aretainer pocket 42 formed therein having an inward or bottom surface 44 lying along afirst plane 46. Such oneside 38 further has a pair ofedge surfaces retainer pocket 42 and lying along a second-intermediate plane 52 spaced outboard of thefirst plane 46. - A generally radially oriented
tongue portion 54 has anouter surface 56 disposed along a third-outer plane 58 spaced outboard of thesecond plane 52. Thetongue portion 54 has a pair of opposite circumferentially spacedsides retainer pocket 42 defines abore 64 extending inward from the third plane 58 adjacent thetongue portion 54 and terminating at the inward surface 44. Thebore 64 has a predetermined diameter so that thebore 64 extends radially outward at a distance greater than the predetermined distance between thesides bore 64 extends outboard of thesides tongue portion 54. Located in thebore 64 theretainer pocket 42 may have analignment configuration 66 shown as being a raised surface or key member. It should be recognized that thealignment configuration 66 is not required for function of the disclosed arrangement and could be a groove or flat surface in thebore 64 or any of a number of other configurations, the use of which will be described later. Thetongue portion 54 is positioned adjacent theretainer pocket 42 and has aconcave surface 68, generally facing the cylindricalexterior surface 12 of thewheel 14, that is formed by thebore 64 of theretainer pocket 42. In addition, theopposite side 40 of themounting block 16 may be configured as described above for the oneside 38. - As best depicted in
FIGS. 5-7 , thereplaceable tip 18 has abody 70 with an exterior ground-engaging surface 72, a mountingend 74 and a mountingblock receiving cavity 76 opening through themounting end 74. The exterior ground-engaging surface 72 has a stepped “plus”-symbol profile to better crush and compact the materials it engages when a compactor wheel moves across waste material or fill dirt. The portions of the “plus” shape that are aligned parallel to the direction of travel of the compactor wheel provide a crushing, grinding and compacting force on the material being compacted, while the portions of the “plus” shape that are transverse to the direction of travel of the wheel provides the traction of the wheel on the refuse material and/or soil being worked. It should be understood thatwheel 14 is a drive wheel, which is driven by the compactor. Therefore, substantial rim-pull forces are transferred from thewheel 14 into the ground through the transverse portions of theteeth 10, such rim pull forces being oriented in the direction ofarrow 77 relative to thewheel 14. While the exterior ground-engaging surface 72 is illustrated in a “plus” configuration, it is to be understood that the profile of the exterior ground-engaging surface 72 of thetip 18 may be formed in a number of other configurations as well. - The
cavity 76 of thetip 18 is configured to receive themounting block 16 and has anupper surface 78 disposed for radial load transferring abutting engagement with thetop surface 32 of themounting block 16. Thecavity 76 also has sidewalls defining a pair of circumferentially spacedside surfaces side surfaces 84,86. The circumferentially spacedside surfaces sides mounting block 16 for transferring the rim pull forces generated by the compactor. - At least one of the axially spaced side surfaces 84 of the
cavity 76 of thetip 18 includes a pair of circumferentially spaced apartribs 88,90 defining a generally radially orientedgroove 92 therebetween and which provides a pair of opposed side surfaces 94,96 and atransverse surface 98. Thegroove 92 is adapted to receive thetongue portion 54 on the mountingblock 16. Thetransverse surface 98 is positionable in a close abutting relationship to theouter surface 56 of thetongue portion 54, while theribs 88,90 are received along their respective edge surfaces 48,50, when thetip 18 is mounted on the mountingblock 16. Upon such mounting, the opposed side surfaces 94,96 of theribs 88,90 are also disposed in close abutting relationship to a respective one of spacedsides tongue portion 54. The sidewall of thecavity 76 with the one axially spacedside surface 84 further includes an annular through-hole 100 located within thegroove 92 and alignable with theretainer pocket 42 in the mountingblock 16. The through-hole 100 is generally coaxially aligned with thebore 64, the purpose of which will become subsequently apparent. Such oneside surface 84 also has alower surface 104 disposed along the mountingend 74, which is in close abutting relation to anaxially extending foot 106 on the mountingblock 16 and employed to transfer axial or side loads between the mountingblock 16 and thetip 18. In addition, the opposite side surface 86 of thetip 18 may be configured as described above for the oneside 84. - Turning now to the
retainer 20, as best shown inFIGS. 8-10 ,such retainer 20 is used for detachably retaining thetip 18 to the mountingblock 16. In one embodiment,retainer 20 includes afastening member 110 and abarrel member 112. Thefastening member 110 is provided with a threadedstud portion 114 and a generallycylindrical head portion 116. Thecylindrical head portion 116 includes atool socket 118 in the end thereof. Disposed between the threadedstud portion 114 and thecylindrical head portion 118 is a taperedportion 120 that blendingly connects the threadedstud potion 114 to thecylindrical head portion 118. - The
barrel member 112 is generally cylindrical in shape and of a predetermined diameter. Thebarrel member 112 is disposed along acentral axis 122 and has a threadedbore 124 in one end thereof that is adapted to be threadably engaged by the threadedstud portion 114 of thefastening member 110. Positioned in the other end of thebarrel member 112 is a taperedsocket 126 that is adapted to be engaged by the taperedportion 120 of thefastening member 110. Afirst end 130 of thebarrel member 112, adjacent the threadedbore 124, includes achamfer 132 that provides a lead for insertion into theretainer pocket 42. Asecond end 136, adjacent the taperedsocket 126, includes a pair of spacedsurfaces mating configuration 144 may be coaxially positioned on the generally cylindrical outer surface of thebarrel member 112 shown as being a groove. It should be recognized that themating configuration 144 could be a raised surface or a flat on the generally cylindrical surface of thebarrel member 112 or any of a number of other configurations that will mate with thealignment configuration 66 in thebore 64 of theretainer pocket 42. - The
barrel member 112 is adapted for receipt into theretainer pocket 42 of the mountingblock 16 and to engage one of thetip 18 or the mountingblock 16 to prevent the rotation of thebarrel member 110 upon the application of a torquing or tightening force thereto by means of a suitable tool which is placed in thetool socket 126 of thefastening member 110. When thetip 18 is placed onto the mountingblock 16, the pair of spacedsurfaces ribs 88,90 of thetip 18. If thealignment configuration 66 and themating configuration 144 are used, thealignment configuration 66 in thebore 64 of theretainer pocket 42 and themating configuration 144 of thebarrel member 112 allow only a specific orientation so that thereplaceable tip 18 is able to be placed on the mountingblock 16. Once thetip 18 is mounted, thefastener member 110 is inserted into the through-hole 100 of theside surface 84 of thecavity 76 of thetip 18 and screwed into the threaded bore 124 of thebarrel member 110. The predetermined diameter of thecylindrical surface 116 of thefastener member 110 is selected for close receipt of thefastener member 110 in the through-hole 100. - Once assembled, the
tip 18 is retained on the mountingblock 16 through engagement of thebarrel member 112 of theretainer 20 by thefastening member 110 through thehole 100 in thetip 18. While not essential, two of theretainers 20 may be employed in retaining thetip 18, one in either side oftooth 10. - The construction of prior compactor teeth enabled rim pull forces acting on the teeth to be exerted on the retaining pins, causing such pins to break. One of the reasons for this is that the primary load transmitting surface employed on the replaceable tip of prior designs and the mating load carrying surface on the mounting base of such teeth are disposed at too great of an angle relative to the direction of the rim pull forces acting on the tooth. As a consequence, a component of the rim pull force acting in an upward radial direction is created. This radial component force tends to rotate the tip about and lift the tip away from its mounting base. In addition, the opposite lower edge of such prior tips contact the compactor wheel when such rim forces are applied. This creates a pivot point about which the tip rotates relative to the mounting base. Due to the distance from this pivot point and pin, the amount of radial movement of the tip at the pin is increased. As the pin is situated to prevent such radial movement, a high resultant force is thereby applied to the pin, which frequently overloads the pin, causing it to break.
- The
compactor tooth 10 of the present invention has a construction especially adapted for transferring rim pull forces exerted on thetip 18 into the mountingblock 16 in a manner so as to isolate the transmission of such forces from theretainer 20, thus reducing the breakage ofsuch retainer 20. In addition, the construction of thepresent retainer 20 and its containment in the tooth maximizes its load carrying capabilities, while at the same time relieving such retainer from experiencing the high loads exerted on the pins of prior compactor teeth devices. - The benefits mentioned above are accomplished by various features of the
present compactor tooth 10. In particular, the circumferentially spacedsides block 16 and the corresponding circumferentially spacedsides tip 18 provide the primary load transferring surfaces for transferring rim pull forces between thetip 18 and mountingblock 16. Such surfaces are oriented substantially perpendicular to such rim pull forces acting in the direction ofarrow 77. - As a consequence, minimal radial components of force are created, thereby reduces the tendency of the
tip 18 to pivot relative to the mountingblock 16. Also, the mountingend 74 of thetip 18 is constructed so as not to contact thecylindrical exterior surface 12 of thewheel 14 when thetip 18 is mounted upon the mountingblock 16. This prevents the edge of thetip 18 from acting as a fulcrum that is located at the greatest distance possible from theretainer 20. In the present structure, such fulcrum is located, if at all, along one of the circumferentially spaced side surfaces 34,36, which are much closer to theretainer 20. Thus, and resulting pivotal movement of the tip at theretainer 20 is reduced as compared to prior compactor teeth. - Retainer breakage is also reduced by the fact that the loads exerted on the
retainer 20 are exerted on the generallycylindrical head portion 116 of thefastening member 110 through thehole 100 in thetip 18 on one side and exerted on thebarrel member 112 through theconcave surface 68 of thetongue portion 56 of the mountingblock 16 on the other side. - While this invention is described and shown for use with a compactor, it is to be understood that the present invention could be readily adapted use in other applications, such as for the juncture between a bucket tooth and adapter. This invention has been described in the specification and illustrated in the drawings with reference to an embodiment, the structure of which has been disclosed herein. However, it will also be understood by those skilled in the art to which this invention pertains that various changes or modifications may be made and equivalents may be substituted for elements of the invention without departing from the scope of the claims. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed in the specification and shown in the drawings as the best mode presently known by the inventors for carrying out this invention, nor confined to the details set forth herein, but that the invention shall include all embodiments, modifications and changes as may come within the scope of the following claims.
