Abstract
An excavator bogie wheel comprises a left and right axle seats, wheel bodies, a shaft, shaft sleeves, floating ring assembles, O-shaped sealing rings, pins and the like. Two shaft sleeves are respectively pressed in from two ends of the roller bodies, one end of the shaft penetrates from one end of the shaft sleeves to the other end, two floating rings assemblies are respectively mounted in the wheel bodies and between the left and right axle seats while compressing for better tightness, pin holes at two ends of the shaft are aligned with pin holes on the left and right axle seats, and two pins are respectively stroke into the pin holes of the left and right axle seats and the shaft. The rim diameter of the wheel body is Phi 250+-5mm, the rim span is 134+-5mm, and rims of the wheel bodies can cross over two guiding ribs on a track shoe and directly support two tracks of the track shoe. Further, the bogie wheel utilizes floating seal inside, which has good sealing effect, the rim diameter of the bogie wheel is larger, the span of two rims of the track roller can be suitable for mounting not only a toothless steel track, but also a rubber track for mating, interchanging of the steel track and rubber track can be directly achieved without replacing the bogie wheel, and the track can be effectively prevented from jumping, thereby reducing manufacturing cost.
Description
(1) technical field:
The utility model belongs to the excavating machine field, relates to the caterpillar wheel of a kind of traxcavator chassis running gear.
(2) background technology:
At present, the common coventional type caterpillar wheel that adopts of the traxcavator chassis running gear of China is and the supporting use of high rail steel crawler belt.If constant line feed walking system parts, then steel crawler belt and rubber belt track can not directly exchange.At present, rubber belt track has been widely used in the walking machine, therefore, not changing under the excavating machine running gear parts situation, reaches steel crawler belt and rubber belt track and directly exchanges, and the caterpillar wheel supporting with it can be general, is the active demand of users institute.
(3) summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, can prevent the derailing, with steel crawler belt and the supporting general-duty traxcavator of rubber belt track caterpillar wheel.
The utility model can achieve the above object with following technical scheme: a kind of excavating machine caterpillar wheel comprises left bracket 1, wheel body 2, axle 3, axle sleeve 4, floating ring assembly 5, right axle seat 6, O-ring seals 7, pin 8; It is characterized in that: after two wheel body 2 welding, eliminate stress, two axle sleeves 4 are pressed into from wheel body 2 two ends respectively, axle 3 is penetrated the other end from an end by axle sleeve 4, in the groove at axle 3 two ends, adorn O-ring seals 7 respectively, two floating ring assemblies 5 are respectively charged between wheel body 2 and the left and right axle bed 1,6, compress left and right axle bed 1,6, the pin-and-hole at axle 3 two ends is alignd with pin-and-hole on the left and right axle bed 1,6, then two pins 8 are squeezed into respectively in the pin-and-hole of left and right axle bed 1,6 and spools 3.
The tip diameter A of wheel body 2 is Φ 250 ± 5mm, and the span B of wheel body 2 is 134 ± 5mm, and can stride across two guiding ribs on the caterpillar block, directly is supported on two tracks of caterpillar block.
The utility model can reach following good effect: adopt floating seal in the caterpillar wheel, after good sealing effect, floating ring in use wear and tear, automatic compensation function is arranged.The tip diameter of caterpillar wheel wheel body is bigger, the span of wheel body two wheel rims not only is fit to and adorn the steel crawler belt of no grouser but also be suitable for adorning rubber belt track supporting, do not change caterpillar wheel steel crawler belt and rubber belt track are directly exchanged, and can prevent crawler belt derailing, load-carrying capacity height simultaneously by actv..Actv. has improved the in-use performance of chassis of dredging machine running gear, has reduced manufacturing cost.
(4) description of drawings:
Fig. 1 is the main TV structure figure of a kind of excavating machine caterpillar wheel of the utility model.
(5) specific embodiment:
As shown in Figure 1, after two wheel bodys, 2 welding with caterpillar wheel, eliminate stress, then two axle sleeves 4 are pressed in the wheel body from wheel body 2 two ends respectively, axle 3 is penetrated the other end from an end by axle sleeve 4, in the groove at axle 3 two ends, adorn O-ring seals 7 respectively, two floating ring assemblies 5 are respectively charged between wheel body 2 and the left and right axle bed 1,6, compress left and right axle bed 1,6, the pin-and-hole at axle 3 two ends is alignd with pin-and-hole on the left and right axle bed 1,6, then two pins 8 are squeezed into respectively in the pin-and-hole of left and right axle bed 1,6 and spools 3.Inject lubricating oil from filler port simultaneously.The wheel rim of caterpillar wheel wheel body 2 can stride across two guiding ribs on the caterpillar block, directly is supported on two tracks of caterpillar block.
The caterpillar wheel assembly is screwed under the longeron of chassis of dredging machine, plays the effect of supporting complete machine.
