Detailed Description
The following description sufficiently illustrates specific embodiments of the invention to enable those skilled in the art to practice and reproduce it.
As shown in fig. 1, is an assembly and decomposition schematic view of the split rear axle structure of the dump truck for medium and mining use of the utility model; as shown in fig. 2, the structure of the split rear axle structure of the dump truck for medium and mining use of the present invention is schematically illustrated.
Split type rear axle structure of mining tipper includes: rear-axle housing 1, left axle sleeve pipe 2, right axle sleeve pipe 3, O type sealing washer 4, packing ring 5 and bolt 6. The left half-shaft sleeve 2 and the right half-shaft sleeve 3 have the same structure.
The sleeve connecting end surfaces of the left half-shaft sleeve 2 and the right half-shaft sleeve 3 are respectively connected with the rear axle housing connecting end surfaces arranged at the left side and the right side of the rear axle housing 1 by bolts 6 and washers 5; and O-shaped sealing rings 4 are arranged between the laminating end faces of the left half-shaft sleeve 2, the right half-shaft sleeve 3 and the rear axle housing 1 to prevent oil in the axle housing from leaking outwards.
As shown in fig. 3, it is a schematic structural diagram of the rear axle housing 1 of the present invention.
The rear axle housing connection end faces of the two sides of the rear axle housing 1 are respectively provided with a first connection flange 11, and the first connection flanges 11 are provided with a plurality of installation threaded holes 12. The rear axle housing has a circular connecting end face and a plurality of mounting threaded holes 12 are arranged in a circle.
As shown in fig. 4, is a schematic structural view of the middle left axle sleeve 2 of the present invention.
The sleeve connecting end faces of the left half-shaft sleeve 2 and the right half-shaft sleeve 3 are provided with a second connecting flange 21, and the second connecting flange 21 is provided with a plurality of mounting through holes 22. The ferrule connection end face is circular, and a plurality of mounting through holes 22 are arranged in a circle.
The positions of the mounting threaded hole 12 and the mounting through hole 22 correspond, and the bolt 6 provided with the washer 5 passes through the mounting through hole 22 and is connected to the mounting threaded hole 12.
