Equally as shown in Figures 3 and 4, wear-resisting cuff 40 can have ducted body 60 conventionally, and it forms level and smooth and continuous inner surface 62 and external surface 64 at least in part.Inner surface 62 can be set to be positioned at wedge portion 44 align member 37 external surface 52 substantially corresponding and coupling.Therefore, inner surface 62 can be set to for example, receive via tight fit (, interference fit) the wedge portion 44 of wearing and tearing, and ducted body 60 can extending axially along the align member 37 in the principal length of wedge portion 44 (that is, more than half length of the wedge portion 44).In one embodiment, ducted body 60 can extend to chamfered edge 54 from transition position 50 in the axial direction.Can there is the skew that thickness be t from inner surface 62 in external surface 64, and have roughly the profile that the profile with inner surface 62 matches.
As align member 37, after assembling, wear-resisting cuff 40 can have single symmetrical plane, and it aligns with plane 58, once this just makes align member 37 insert wear-resisting cuff 40, the single symmetry of these parts can contribute to stop relatively rotating between them.Plane 58 can be passed two positions that separate inner surface 62.In first such position (position, lower-left as shown in Figure 3), inner surface 62 conventionally can with the axially aligning of align member 37.In second such position (upper-right position as shown in Figure 3), the angle [alpha] that inner surface 62 can be certain with respect to axioversion.
The ducted body 60 of wear-resisting cuff 40 can also comprise the first axial end portion 66(or the outer axial end portion 66 that is positioned at chamfered edge 54) with relative the second axial end portion 68(or the axial end portion 68 that are positioned at transition position 50).In the disclosed embodiment, it is oval that the inner surface 62 of the first axial end portion 66 is generally, and the inner surface 62 of the second axial end portion 68 is generally circular.Yet, can be expected that, if necessary, the inner surface 62 of the first and second ends 66,68 can be replaced by oval-shaped.In arbitrary configuration, the inner surface 62 of the first axial end portion 66 can have minor diameter D
1(the minor diameter d of the inner surface 62 of itself and the second axial end portion 68
1about equally), and major diameter D
2(it is than the major diameter d of the inner surface of the second axial end portion 68 62
2approximately large 10-30%).The thickness that this geometrical relationship can provide at the second axial end portion 68 and internal diameter be than being about 1:3-4, and thickness with axial length than being about 1:2.5-3.5, this can contribute to guarantee have enough intensity and suitable cooperation in holes 30,34 of wearing and tearing.Wear-resisting cuff 40 can be made by substantially identical with manufacturing align member 37 material, makes wear-resisting cuff 40 to wear and tear and to provide support with the essentially identical mode of align member 37.In other embodiments, wear-resisting cuff 40 can be made by the material different from manufacturing align member 37, thereby compares with the align member 37 that lacks wear-resisting cuff, and wear-resisting cuff 40 provides improved abrasion resistance properties.
Through operation after a while, the different parts of equipment 12, GET 14 and/or fixed system 24 can wear and tear.As will be described below in more detail, wear-resisting cuff 40 can optionally be assembled to adapt to this wearing and tearing around the align member 37 of wearing and tearing, and contributes to guarantee the suitable engaging condition between GET 14 and equipment 12.But possible, the wearing and tearing meeting in some places is more serious than other place, and/or wearing and tearing depend on age or the useful life of machine 10.In order to adapt to different application and/or working environment, the wear-resisting cuff kit of producing can have a plurality of different wear-resisting cuffs 40.This kit can comprise the wear-resisting cuff of many covers, the wear-resisting cuff of every cover comprises two wear-resisting cuffs, and there is different thickness t, its configuration by the relative motion between different amount limit adaptation devices 20 and installation protuberance 22 (is for example used for, the first cuff is running-in wear, the second cuff comparable the former thick approximately 10% to adapt to more serious wearing and tearing).In addition, this kit can comprise for removing align member 37 and/or existing wear-resisting cuff 40, and for assembling the manual of the wear-resisting cuff 40 of replacement with different-thickness.This kit can have single component numbering, this means that this kit can be used as a single product form and ordered and distribute to customer.In certain embodiments, if necessary, replace bolt 38 and/or seal (not shown) and also can be included in kit.
Fig. 5 shows another kind of substituting fixed system 70.In the present embodiment, fixed system 70 comprises single align member 72, bolt 74, fixed component 76 and wear-resisting cuff 78.From a side of GET 14, align member 72 can be inserted into by adapter 20 and the hole 30 and 34 that protuberance 22 is installed respectively.Bolt 74 can be inserted into fixed component 76, and the hole 34 of the installation protuberance 22 of the opposite side of the GET 14 that then fixed component 76 can engage by the inside end with align member 72 is inserted into.Then the tension force of bolt 74 can work and further make align member 72 enter in hole 30,34, thus fastening adapter 20 with being connected of protuberance 22 is installed.Wear-resisting cuff 78, as will be described below in more detail, at fixed system 70(align member 72) other parts and/or GET 14(for example, hole 30,34) after wearing and tearing, can strengthen engaging of adapter 20 and installation protuberance 22.Can be expected that, if necessary, fixed system 70 can comprise additional parts, one or more seals that intermediate host member, the one or more pins that stop bolt 74 rotations, prevention dirt and the chip rotating such as one or more prevention align members 72 enters, pad etc.
As shown in Figures 6 and 7, align member 72 can have similar shape, and provides and the similar function of align member shown in Fig. 3,4 37.Yet, with align member 37 by contrast, align member 72 can have facet.Be that align member 72 can comprise shank 80 and wedge portion 82, the two is formed by a plurality of generally planar adjacently situated surfaces.The corresponding generally planar surface that these generally planar surfaces can be configured to engage adapter 20, protuberance 22 and/or fixed component 76 are installed, thereby undesirable rotation of inhibition align member 72.
Wear-resisting cuff 78 in Fig. 6 and 7, as the wear-resisting cuff 40 in Fig. 3 and 4, can be configured to receive in inside the align member 72 of wearing and tearing.Yet due to the geometry difference between align member 37 and 72, the shape of wear-resisting cuff 78 can be different from wear-resisting cuff 40.Especially, the inside and outside portion surface 84,86 of wear-resisting cuff 78 can have facet, so as with the outline of align member 72 and adapter 20, interior outline that protuberance 22 and/or fixed component 76 are installed.
industrial applicibility
The disclosed wear-resisting cuff of the utility model and instrument fixed system go for various earthwork machines, as cable shovel, wheel loader, excavator, front shovel, excavator and bulldozer.When ground engagement instrument is detachably connected to the equipment of these machines, equipment can be protected and make to meet with destructive friction and shock zone is avoided wearing and tearing.Therefore, disclosed instrument fixed system contributes to the application life of extension fixture and machine.After operation a period of time, 24 couples of GET 14 of instrument fixed system of use and equipment 12 be connected and the improvement of wearing and tearing will elaborate.
After operation after a while, due to wearing and tearing, the joint between equipment 12 and GET 14 can become loosening.If do not paid attention to, the lasting use under this condition may cause the damage of these expensive components.Therefore, Service Technicians can make regular check on the joint between equipment 12 and GET 14.When observing between equipment 12 and GET 14 significant motion (amount is about threshold level), the removable and maintenance fixed system 24 of service technician.
Service Technicians can remove fixed system 24 by discharging the tension force of bolt 38 inside.In certain embodiments, plug (not shown) may need to be removed, to approach the head end of bolt 38.Once the tension force of bolt 38 is released, one or two align member 37 can be from hole 30,34 be removed (that is, being pounded out).According to the abrasion condition having produced, Service Technicians can select one or more wear-resisting cuff 40(with corresponding thickness from above-described kit) use.Then wear-resisting cuff 40 can be installed in align member 37 tops that are removed and wear and tear, and align member 37 and wear-resisting cuff 40 can be inserted backward by corresponding hole 30,34 subsequently.Bolt 38 can be by retighten, to strengthen the engaging of installation protuberance 22 of adapter 20 and equipment 12.
After another section wearing and tearing, the wear-resisting cuff 40 of previously having installed may need to be replaced by the wear-resisting cuff 40 of the difference with larger thickness in kit.This process can complete with very identical mode described above.Especially, the tension force in bolt 38 can be released, and when corresponding align member 37 removes, the wear-resisting cuff 40 of previously having installed is removed from align member 37, thicker wear-resisting cuff 40 is installed, and all parts are replaced together.Yet, can be expected that, in certain embodiments, if the need arises, be not the wear-resisting cuff 40 of removing wearing and tearing, but extra wear-resisting cuff 40 can be installed simply above the wear-resisting cuff 40 of existing wearing and tearing.The maintenance of fixed system 70 can be carried out in the same manner as described above.
Fixed system disclosed in the utility model can be relatively simple and cheap.Particularly, because the parts of wearing and tearing can continue to be used, by the strengthening of wear-resisting cuff 40, the running cost of machine 10 can be lower.In addition, due to wear-resisting cuff 40 can excessive resorption wearing and tearing, the machine 10 comparatively damage of expensive parts can be avoided.
Clearly, those skilled in the art can carry out various modifications and variations to disclosed wear-resisting cuff and fixed system.From manual and the practice of disclosed wear-resisting cuff and fixed system, consider, other embodiment will be apparent to those skilled in the art.For example, although wear-resisting cuff 40 and 78 is described to only just be used after the miscellaneous part wearing and tearing of GET 14 and/or fixed system 24, can be expected that, wear-resisting cuff 40,78 is optionally used in new configuration, then after they self are worn, changes.Rely on this mode, other parts of GET 14 and/or fixed system 24 may suffer less running-in wear.Can further imagine, wear-resisting cuff 40,78 can be made by softer material, and it can make most wearing and tearing occur in the inside of wear-resisting cuff rather than the inside of other component.Manual and embodiment are only regarded as exemplary, real protection domain and are embodied on claim and equivalent thereof.
