Abstract
The utility model relates to an excavator supporting wheel with high sealing performance, which comprises a supporting wheel shaft arranged inside a supporting wheel body. Two symmetrical bearings are arranged between the supporting wheel shaft and the supporting wheel body; an oil seal seat connected with the supporting wheel body is arranged at the left end of the supporting wheel body; the joint of the oil seal seat and the supporting wheel body is sealed by a floating sealing ring and a floating sealing rubber ring; an end plate is arranged at the right end of the supporting wheel shaft; a supporting wheel cover connected with the supporting wheel body is arranged on the right side of the end plate; and an oil plug is arranged in the middle of the right end face of the supporting wheel cover. The excavator supporting wheel with the high sealing performance, which is provided by the utility model, has a simple structure, is convenient to use and install, has good sealing performance between parts, can bear a larger weight, has long service life and is suitable to popularize and apply in a large range.
Description
Technical field
This patent relates to a kind of excavating machine support roller with 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, so excavating machine also becomes the very high equipment of breakage rate; Wherein the excavating machine support roller is that the excavating machine parts hold damageable parts most, and support roller is the vitals of traxcavator walking and support system, and generally, support roller is the carrier that bears whole machinery weight; Technical requirements is higher, but riding wheel structure is complicated at present, and mass ratio is higher; Poor sealing performance causes support roller very easily to damage, and uses and install extremely inconvenience; Brought great trouble to the user, very easily damage simultaneously, and the life-span has been shorter.
The utility model content
For solving the problems of the technologies described above, this patent provides a kind of excavating machine support roller with high sealing performance simple in structure, easy to use.
The excavating machine support roller with high sealing performance of this patent; Comprise being arranged on support roller body in-to-in supporting-roller shaft, be provided with two symmetrical bearings between supporting-roller shaft and the support roller body, the left end of support roller body is provided with and support roller body bonded assembly oil seal seat; Oil seal seat and support roller body junction are through floating sealing ring and the sealing of floating sealing circle; The right-hand member of supporting-roller shaft is provided with end plate, and the right side of end plate is provided with and support roller body bonded assembly support roller lid, and the middle part, right side of support roller lid is provided with plug cock.
The excavating machine support roller with high sealing performance of this patent passes through bolt between said end plate and the supporting-roller shaft.
The excavating machine support roller with high sealing performance of this patent, said support roller lid is lined with circlip with the junction of support roller body.
Compared with prior art the beneficial effect of this patent is: the excavating machine riding wheel structure with high sealing performance of this patent is simple; Easy to install and use, good seal performance between each parts can be born very big weight; Long service life suits to apply on a large scale.

Fig. 1 is the described a kind of structural representation with excavating machine support roller of high sealing performance of this patent embodiment.
Among the figure:
1, support roller body; 2, supporting-roller shaft; 3, bearing; 4, oil seal seat; 5, floating sealing ring; 6, floating sealing circle; 7, end plate; 8, support roller lid; 9, plug cock; 10, circlip.
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 support roller with high sealing performance comprises being arranged on support roller body 1 in-to-in supporting-roller shaft 2; Be provided with two symmetrical bearings 3 between supporting-roller shaft 2 and the support roller body 1; The left end of support roller body 1 is provided with and support roller body 1 bonded assembly oil seal seat 4, and oil seal seat 4 seals through floating sealing ring 5 and floating sealing circle 6 with support roller body 1 junction, and the right-hand member of supporting-roller shaft 2 is provided with end plate 7; The right side of end plate 7 is provided with and support roller body 1 bonded assembly support roller lid 8, and the middle part, right side of support roller lid 8 is provided with plug cock 9.
The excavating machine support roller with high sealing performance of this patent passes through bolt between said end plate 7 and the supporting-roller shaft 2.
The excavating machine support roller with high sealing performance of this patent, said support roller lid 8 is lined with circlip 10 with the junction of support roller body 1.
The excavating machine riding wheel structure with high sealing performance of this patent is simple, easy to install and use, and good seal performance between each parts can be born very big weight, and long service life suits to apply on a large scale.
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.
