Abstract
The invention relates to an excavator supporting wheel with high sealing properties. The supporting wheel comprises a supporting shaft, a supporting wheel body is sleeved on the exterior of the supporting shaft, an iron sleeve piece is arranged between the supporting wheel body and the supporting shaft, shaft seats sleeved on the supporting shaft are arranged on two end faces of the supporting wheel body, connection positions of the shaft seats with the supporting wheel body are sealed through floating seal rings and floating seal rubber rings, an oil passage is arranged inside the supporting shaft, and an oil plug is arranged at the end portion of the oil passage. According to the excavator supporting wheel with high sealing properties, the structure is simple, the shaft seats and the supporting wheel body are fixed through bolts, connecting soundness is improved, tightness among all components is good through arrangement of O-shaped rings, floating seal rings and floating seal rubber rings; and the supporting wheel is convenient to use and mount, and the service life is long.
Description
Technical field
This patent relates to a kind of excavating machine caterpillar wheel of high sealing performance.
Background technology
Along with the continuous development of society, large-scale construction project is constantly implemented, and in construction project, all will use excavating machine; Therefore excavating machine also becomes the very high equipment of breakage rate, and wherein the excavating machine caterpillar wheel is that the excavating machine parts hold damageable parts most, and caterpillar wheel is the vitals of traxcavator walking and support system; Generally, caterpillar wheel is the carrier that bears whole machinery weight, and technical requirements is higher; But present caterpillar wheel complex structure, leak tightness is poor between each parts, causes oil leak; Outside dust also gets into caterpillar wheel inside easily simultaneously, and then caterpillar wheel is reduced service life greatly, has brought great trouble to the user; Productive costs is high simultaneously, very easily damage, and the life-span is shorter.
Patent content
For solving the problems of the technologies described above, this patent provides a kind of excavating machine caterpillar wheel of high sealing performance simple in structure, easy to use.
The excavating machine caterpillar wheel of the high sealing performance of this patent; Comprise fulcrum, the outside of said fulcrum is with the caterpillar wheel body, and the iron engagement piece is set between caterpillar wheel body and the fulcrum; The both ends of the surface of caterpillar wheel body are provided with the axle bed that is enclosed within on the fulcrum; The junction of axle bed and caterpillar wheel body is through floating sealing ring and the sealing of floating sealing circle, and the inside of fulcrum is provided with oil leab, and the end of oil leab is provided with plug cock.
The excavating machine caterpillar wheel of the high sealing performance of this patent passes through bolt between said axle bed and the caterpillar wheel body.
The excavating machine caterpillar wheel of the high sealing performance of this patent is equipped with O shape circle between said axle bed and the fulcrum and between iron engagement piece and the caterpillar wheel body.
Compared with prior art the beneficial effect of this patent is: the excavating machine caterpillar wheel of the high sealing performance of this patent is simple in structure; Pass through bolt between axle bed and the caterpillar wheel body; Improved the bonded assembly fastness; Through O shape circle, floating sealing ring and floating sealing circle are set, make better tightness between each parts; Easy to install and use, the life-span is long.
Description of drawings
Fig. 1 is the structural representation of the excavating machine caterpillar wheel of the described a kind of high sealing performance of this patent embodiment.
Among the figure:

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of this patent is described in further detail.Following examples are used to explain this patent, but are not used for limiting the scope of this patent.
As shown in Figure 1, a kind of excavating machine caterpillar wheel of high sealing performance comprises fulcrum 1; The outside of said fulcrum 1 is with caterpillar wheel body 2; Between caterpillar wheel body 2 and the fulcrum 1 iron engagement piece 3 is set, the both ends of the surface of caterpillar wheel body 2 are provided with the axle bed 4 that is enclosed within on the fulcrum 1, and axle bed 4 seals through floating sealing ring 5 and floating sealing circle 6 with the junction of caterpillar wheel body 2; The inside of fulcrum 1 is provided with oil leab, and the end of oil leab is provided with plug cock 7.
The excavating machine caterpillar wheel of the high sealing performance of this patent passes through bolt between said axle bed 4 and the caterpillar wheel body 2.
The excavating machine caterpillar wheel of the high sealing performance of this patent is equipped with O shape circle 8 between said axle bed 4 and the fulcrum 1 and between iron engagement piece 3 and the caterpillar wheel body 2.
The excavating machine caterpillar wheel of the high sealing performance of this patent is simple in structure, through bolt, has improved the bonded assembly fastness between axle bed 4 and the caterpillar wheel body 2, through O shape circle 8, floating sealing ring 5 and floating sealing circle 6 are set, makes better tightness between each parts; Easy to install and use, the life-span is long.
The above only is the preferred implementation of this patent; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the patent art principle; Can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of this patent.
