Abstract
The utility model relates to a thrust wheel for a traveling device of an excavator. The thrust wheel comprises a double-side thrust wheel body, wherein a support shaft is arranged inside the double-side thrust wheel body; shaft seats connected with the double-side thrust wheel body are respectively arranged at two ends of the support shaft; the connected parts of the shaft seats and the double-side thrust wheel body are respectively sealed by a floating seal ring and a floating seal rubber ring; a lubricating oil path is arranged inside the support shaft; and an oil plug is arranged at the end part of the lubricating oil path. The thrust wheel for the traveling device of the excavator has the advantages of compact structure, convenience in mounting and maintaining, long service life, low production cost and suitability for wide-range popularization and application; and due to the arrangement of the floating seal ring and the floating seal rubber ring, favorable sealing performance can be achieved.
Description
Technical field
This patent relates to a kind of caterpillar wheel of excavator walking device.
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 bilateral caterpillar wheel complex structure, mass ratio is higher, has brought great trouble to the user; Productive costs is high simultaneously, very easily damage, and the life-span is shorter.
The utility model content
For solving the problems of the technologies described above, this patent provides a kind of caterpillar wheel of excavator walking device simple in structure, easy to use.
The caterpillar wheel of the excavator walking device of this patent; Comprise bilateral caterpillar wheel body; The inside of said bilateral caterpillar wheel body is provided with fulcrum, and the two ends of fulcrum are respectively equipped with and bilateral caterpillar wheel body bonded assembly axle bed, and the junction of axle bed and bilateral caterpillar wheel body is respectively through floating sealing ring and the sealing of floating sealing circle; The inside of fulcrum is provided with oil leab, and the end of oil leab is provided with plug cock.
The caterpillar wheel of the excavator walking device of this patent, the junction of said bilateral caterpillar wheel body and fulcrum is provided with the iron engagement piece, and the junction of iron engagement piece and bilateral caterpillar wheel body is provided with O shape circle.
Compared with prior art the beneficial effect of this patent is: the caterpillar wheel compact conformation of the excavator walking device of this patent; Convenient for installation and maintenance, through floating sealing ring being set and floating sealing circle can reach good sealing property, long service life; Productive costs is low, suits to apply on a large scale.
Description of drawings
Fig. 1 is the structural representation of the caterpillar wheel of the described excavator walking device of this patent embodiment.
Among the figure:
1, bilateral caterpillar wheel body; 2, fulcrum; 3, axle bed; 4, floating sealing ring; 5, floating sealing circle; 6, oil leab; 7, plug cock; 8, iron engagement piece; 9, O shape circle.
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 caterpillar wheel of excavator walking device comprises bilateral caterpillar wheel body 1, and the inside of said bilateral caterpillar wheel body 1 is provided with fulcrum 2; The two ends of fulcrum 2 are respectively equipped with and bilateral caterpillar wheel body 1 bonded assembly axle bed 3; Axle bed 3 seals through floating sealing ring 4 and floating sealing circle 5 respectively with the junction of bilateral caterpillar wheel body 1, and the inside of fulcrum 2 is provided with oil leab 6, and the end of oil leab 6 is provided with plug cock 7.
The caterpillar wheel of the excavator walking device of this patent, said bilateral caterpillar wheel body 1 is provided with iron engagement piece 8 with the junction of fulcrum 2, and iron engagement piece 8 is provided with O shape circle 9 with the junction of bilateral caterpillar wheel body 1.
The caterpillar wheel compact conformation of the excavator walking device of this patent, convenient for installation and maintenance, through floating sealing ring being set and floating sealing circle can reach good sealing property, long service life, productive costs is low, suitablely applies on a large scale.Welding all is to adopt friction welding between each parts in addition, the relatively good processing of the processing of weld seam, and the connection of parts is also compact; The floating pressure of vacuum is adopted in plug cock and oil lubrication; Quality is low weight, and material is relatively economized, because under the situation that does not influence intensity, all adopt designs such as hole, spoke to hollow out in unnecessary portions on some parts, reduces materials.
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.
