Abstract
The utility model relates to a single rim bearing wheel with a compact structure for an excvavtor, which comprises a bearing wheel body, wherein a bearing shaft is arranged in the bearing wheel body, an iron shrinking-on part is arranged between the bearing shaft and the bearing wheel body, two ends of the bearing shaft are respectively provided with a shaft seat connected with the bearing wheel body, and the connection positions of the shaft seats and the bearing wheel body are respectively sealed through floating seal rings and floating sealing rubber rings. The single rim bearing wheel with the compact structure for the excvavtor is compact in structure, convenient in installation and maintenance, long in service life, low in production cost, suitable for wide-range popularization and application and capable of achieving good sealing performance by means of the floating seal rings and the floating sealing rubber rings.
Description
Technical field
This patent relates to a kind of excavating machine single rim bearing wheel of compact conformation.
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 single rim bearing wheel complex structure, mass ratio is higher, has brought great trouble to the user; Very easily damage simultaneously, 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 excavating machine single rim bearing wheel of simple in structure, easy to use, compact conformation.
The excavating machine single rim bearing wheel of the compact conformation of this patent; Comprise the caterpillar wheel body; The inside of said caterpillar wheel body is provided with fulcrum; Between fulcrum and the caterpillar wheel body iron engagement piece is set, the two ends of fulcrum are respectively equipped with and caterpillar wheel body bonded assembly axle bed, and the junction of axle bed and caterpillar wheel body is respectively through floating sealing ring and the sealing of floating sealing circle.
The excavating machine single rim bearing wheel of the compact conformation of this patent, the inside of said fulcrum is provided with oil leab, and the right-hand member of oil leab is provided with plug cock.
The excavating machine single rim bearing wheel of the compact conformation of this patent passes through screw retention between said axle bed and the caterpillar wheel body.
Compared with prior art the beneficial effect of this patent is: the excavating machine single rim bearing wheel compact conformation of the compact conformation 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 excavating machine single rim bearing wheel of the compact conformation of the described a kind of this patent of this patent embodiment.
Among the figure:
1, caterpillar wheel body; 2, fulcrum; 3, iron engagement piece; 4, axle bed; 5, floating sealing ring; 6, floating sealing circle; 7, plug cock.
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 single rim bearing wheel of compact conformation; Comprise caterpillar wheel body 1, the inside of said caterpillar wheel body 1 is provided with fulcrum 2, between fulcrum 2 and the caterpillar wheel body 1 iron engagement piece 3 is set; The two ends of fulcrum 2 are respectively equipped with and caterpillar wheel body 1 bonded assembly axle bed 4, and axle bed 4 seals through floating sealing ring 5 and floating sealing circle 6 respectively with the junction of caterpillar wheel body 1.
The excavating machine single rim bearing wheel of the compact conformation of this patent, the inside of said fulcrum 2 is provided with oil leab, and the right-hand member of oil leab is provided with plug cock 7.
The excavating machine single rim bearing wheel of the compact conformation of this patent passes through screw retention between said axle bed 4 and the caterpillar wheel body 1.
The excavating machine single rim bearing wheel compact conformation of the compact conformation 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.
