Abstract
The utility model relates to a single rim bearing wheel of an excavator. The single rim bearing wheel comprises a single rim bearing wheel body; a fulcrum shaft is arranged in the single rim bearing wheel body; an iron fitting element is arranged between the fulcrum shaft and the single rim bearing wheel body; shaft seats connected with the single rim bearing wheel body are arranged at the two ends of the fulcrum shaft respectively; the shaft seat and the single rim bearing wheel body are both fixed by a plurality of bolts; and an oil plug is arranged at the right end of the fulcrum shaft. The single rim bearing wheel of the excavator is impact in structure, convenient to install and maintain and capable of achieving excellent sealing performance by arranging a floating seal ring and a floating seal rubber ring, has long service life and low production cost and is suitable for large-scale promotion and application.
Description
Technical field
This patent relates to a kind of excavating machine single rim bearing wheel.
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 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, installs, uses and keep in repair trouble, 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 excavating machine single rim bearing wheel simple in structure, easy to use.
The excavating machine single rim bearing wheel of this patent; Comprise the single rim bearing wheel body; The inside of said single rim bearing wheel body is provided with fulcrum, is provided with the iron engagement piece between fulcrum and the single rim bearing wheel body, and the two ends of fulcrum are respectively equipped with and single rim bearing wheel body bonded assembly axle bed; Axle bed and single rim bearing wheel body are all through some bolt, and the inside of the right-hand member of fulcrum is provided with plug cock.
The excavating machine single rim bearing wheel of this patent, the junction of said axle bed and single rim bearing wheel body are respectively through floating sealing ring and the sealing of floating sealing circle.
The excavating machine single rim bearing wheel of this patent, the junction of the junction of said axle bed and fulcrum and fulcrum and single rim bearing wheel body all are provided with O shape circle.
Compared with prior art the beneficial effect of this patent is: the excavating machine single rim bearing wheel 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 the described a kind of excavating machine single rim bearing wheel of this patent embodiment.
Among the figure:
1, single rim bearing wheel body; 2, fulcrum; 3, iron engagement piece; 4, axle bed; 5, plug cock; 6, floating sealing ring; 7, floating sealing circle; 8, 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 excavating machine single rim bearing wheel comprises single rim bearing wheel body 1, and the inside of said single rim bearing wheel body 1 is provided with fulcrum 2; Be provided with iron engagement piece 3 between fulcrum 2 and the single rim bearing wheel body 1; The two ends of fulcrum 2 are respectively equipped with and single rim bearing wheel body 1 bonded assembly axle bed 4, and axle bed 4 and single rim bearing wheel body 1 are all through some bolt, and the inside of the right-hand member of fulcrum 2 is provided with plug cock 5.
The excavating machine single rim bearing wheel of this patent, said axle bed 4 seals through floating sealing ring 6 and floating sealing circle 7 respectively with the junction of single rim bearing wheel body 1.
The excavating machine single rim bearing wheel of this patent, said axle bed 4 all is provided with O shape circle 8 with the junction of fulcrum 2 and the junction of fulcrum 2 and single rim bearing wheel body 1.
The excavating machine single rim bearing wheel 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.
