Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1-2, the utility model embodiment, a kind of excavator walking assembly, including walker 1, walker 1
Turgor cylinder 2 is inside installed, the inner side of turgor cylinder 2 is provided with oil filler cover plate 18, and the right side of turgor cylinder 2 is provided with the right side
Track beam 3, right-hand track chiain beam 3 is arranged on the right-hand member of walker 1, right-hand track chiain beam 3 and is provided with guide wheel 4, the left end of walker 1
Outside, which is connected with hydraulic motor travel motor 5, hydraulic motor travel motor 5, is provided with driving wheel 6, and the front side both sides of hydraulic motor travel motor 5 are equal
Heavy-duty spring packing ring 7 and interior hexagonal screw thread 8 are provided with, hydraulic motor travel motor 5 passes through heavy-duty spring packing ring 7 and interior hexagonal screw thread 8
On walker 1, the middle part both sides of hydraulic motor travel motor 5 are provided with Allen bolt 9 and heavy-duty spring packing ring 7, walking
Two size identical support sprocket wheels 10 are installed, the lower end of walker 1 is provided with eight size identical thrust wheels 11 on frame 1,
Sliding bearing 17 is provided with thrust wheel 11, is supported and connected using sliding bearing 17, and inside is provided with float grease seal, walker 1
Lower middle side part is provided with two block size identical baffle plates 16, guide wheel 4, driving wheel 6, support sprocket wheel 10 and the elongate support of thrust wheel 11
The surface coated track rail assembly 12 of walker 1, guide wheel 4 is used for guiding crawler belt correctly to operate, and can prevent its sideslip and exceed the bounds,
The guide wheel 4 of most hydraulic crawler excavator plays a part of thrust wheel 11 simultaneously, and so crawler belt that can increase is to ground
Contact area, reduces than pressure, smooth surface is made in the wheel face of guide wheel 4 mostly, and centre has shoulder block ring to make guide effect, the anchor ring of both sides
