Abstract
The utility model relates to a thrust wheel for an excavator. The thrust wheel comprises a thrust wheel body, wherein a support shaft is arranged inside the thrust wheel body; an outer shaft seat and an inner shaft seat which are connected with the thrust wheel body are respectively arranged at two ends of the support shaft; a shaft sleeve is arranged between the support shaft and the thrust wheel body; and the support shaft is fixed with the inner shaft seat by a cylindrical pin. The thrust wheel for the excavator, which is disclosed by the utility model, 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 a floating seal ring and a floating seal rubber ring, favorable sealing performance can be achieved.
Description
Technical field
This patent relates to a kind of excavating machine caterpillar wheel.
Background technology
Caterpillar wheel is the vitals of traxcavator walking and support system, and generally, caterpillar wheel is the carrier that bears whole machinery weight; Technical requirements is higher, but present caterpillar wheel complex structure, and mass ratio is higher; Install, use and keep in repair trouble, 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 caterpillar wheel simple in structure, easy to use.
The excavating machine caterpillar wheel of this patent; Comprise the caterpillar wheel body, the inside of said caterpillar wheel body is provided with fulcrum, and the two ends of fulcrum are respectively equipped with and outer axle bed of caterpillar wheel body bonded assembly and interior axle bed; Be provided with axle sleeve between fulcrum and the caterpillar wheel body, fix through straight pin between fulcrum and the interior axle bed.
The excavating machine caterpillar wheel of this patent, said fulcrum all seals through floating sealing ring and floating sealing circle with the junction of outer axle bed and the junction of fulcrum and interior axle bed.
Compared with prior art the beneficial effect of this patent is: the excavating machine caterpillar 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 caterpillar wheel of this patent embodiment.
Among the figure:
1, caterpillar wheel body; 2, fulcrum; 3, outer axle bed; 4, interior axle bed; 5, axle sleeve; 6, straight pin; 7, floating sealing ring; 8, floating sealing 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 caterpillar wheel; Comprise caterpillar wheel body 1, the inside of said caterpillar wheel body 1 is provided with fulcrum 2, and the two ends of fulcrum 2 are respectively equipped with and outer axle bed 3 of caterpillar wheel body 1 bonded assembly and interior axle bed 4; Be provided with axle sleeve 5 between fulcrum 2 and the caterpillar wheel body 1, fixing between fulcrum 2 and the interior axle bed 4 through straight pin 6.
The excavating machine caterpillar wheel of this patent, said fulcrum 2 all seals through floating sealing ring 7 and floating sealing circle 8 with the junction of outer axle bed 3 and the junction of fulcrum 2 and interior axle bed 4.
The excavating machine caterpillar 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.
