Abstract
The present invention proposes a kind of good digging machine chassis of stability, including two crawler bodies, coats one layer of crawler belt on each crawler body, arranged in parallel between two crawler bodies, is connected between two crawler bodies by connecting shaft；Cladding sets a bushing outside the connecting shaft, the connecting shaft is the column structure that end face is square structure, bushing interference fit is fixed on outside connecting shaft, bushing periphery is cylindrical structure, the length of bushing is less than the length of connecting shaft, and structure is novel, easy for installation, the intensity of axle can be effectively improved, improves the stability on digging machine chassis.
Description
Technical field
The present invention relates to a kind of digging machine chassis, and in particular to a kind of good digging machine chassis of stability.
Background technology
Excavator, also known as excavating machinery (excavating machinery), it is to be excavated to be higher or lower than with scraper bowl to hold machine
The material in face, and load haulage vehicle or unload to the earthmoving machinery of rickyard.Excavator excavate material be mainly soil, coal,
Silt and soil and rock after pre- pine.From the point of view of the development of engineering machinery in recent years, the development of excavator is relatively
It hurry up, excavator has become one of most important engineering machinery in engineering construction.
Chassis is one of basic element of character of excavator, and axle is to connect the part between two chassis, existing axle intensity
Not enough, easy fracture.
The content of the invention
The present invention proposes a kind of good digging machine chassis of stability regarding to the issue above, and structure is novel, easy for installation, can
The intensity of axle is effectively improved, improves the stability on digging machine chassis.
Specific technical scheme is as follows：
A kind of good digging machine chassis of stability, including two crawler bodies, one layer of crawler belt, two shoes are coated on each crawler body
It is arranged in parallel between band chassis, connected between two crawler bodies by connecting shaft；
Cladding sets a bushing outside the connecting shaft, and the connecting shaft is the column structure that end face is square structure, lining
Set interference fit is fixed on outside connecting shaft, and bushing periphery is cylindrical structure, and the length of bushing is less than the length of connecting shaft；
The bushing includes liner body, axial on liner body alternate to be provided with the first axis hole group and the second axis hole group；The
One axis hole group and the second axis hole group are arranged alternately composition, the first axle hole position of the first axis hole group by the first axis hole and the second axis hole
In the top of the second axis hole of the second axis hole group.
Further, first axis hole is regular hexagon structure.
Further, second axis hole is circular configuration.
Further, the inscribe for the regular hexagon structure that the circular configuration that second axis hole is in is in by the first axis hole
Circle.
Further, the distance between two neighboring first axis hole and the second axis hole and two neighboring axle in same axis hole group
The distance between two neighboring first axis holes of Kong Zuzhong and the second axis hole are equal.
Beneficial effects of the present invention are：Structure of the present invention is novel, easy for installation, can effectively improve the intensity of axle.
Brief description of the drawings
Fig. 1 is structure chart of the present invention.
Fig. 2 is connecting axle structure figure of the present invention.
Embodiment
To make technical scheme become apparent from clearly, below the present invention is described further, it is any to this

One layer of crawler belt of cladding on a kind of good digging machine chassis of stability, including two 7 each crawler bodies of crawler body, two
It is arranged in parallel between individual crawler body, connected between two crawler bodies by connecting shaft；
6 claddings of the connecting shaft set a bushings, and the connecting shaft is the column structure that end face is square structure, bushing
Interference fit is fixed on outside connecting shaft, and bushing periphery is cylindrical structure, and the length of bushing is less than the length of connecting shaft；
The bushing includes liner body 1, axial on liner body alternate to be provided with the first axis hole group 2 and the second axis hole group 3；
First axis hole group and the second axis hole group are arranged alternately composition, the first axle of the first axis hole group by the first axis hole 4 and the second axis hole 5
Hole position is in the top of the second axis hole of the second axis hole group.
Further, first axis hole is regular hexagon structure.
Further, second axis hole is circular configuration.
Further, the inscribe for the regular hexagon structure that the circular configuration that second axis hole is in is in by the first axis hole
Circle.
Further, the distance between two neighboring first axis hole and the second axis hole and two neighboring axle in same axis hole group
The distance between two neighboring first axis holes of Kong Zuzhong and the second axis hole are equal.
