Detailed Description
The following description fully illustrates the specific embodiments of the invention to enable those skilled in the art to practice and reproduce it.
Fig. 1 is a schematic diagram of the overall structure of the D-shaped split rear axle housing assembly of the mining dump truck.
D-shaped split rear axle housing assembly of mining dump truck, which comprises: the rear axle housing 1, the half axle sleeve 2 and the bolts 3, wherein the two half axle sleeves 2 are respectively connected to the two ends of the rear axle housing 1 through the bolts 3.
As shown in fig. 2, a rear axle housing 1 in the present invention is shown in a sectional view.
The rear axle housing 1 is provided with inner cylindrical surfaces 11 at both ends, and the inner cylindrical surfaces 11 at both ends have the same diameter.
As shown in fig. 3, a side view of the rear axle housing 1 in the present invention.
The rear axle housing 1 is provided with a D-shaped screw hole group at the end of the outer side of the inner cylindrical surface 11, the D-shaped screw hole group including: a C-shaped set of threaded holes 12 and a longitudinal set of threaded holes 13. The longitudinal screw hole group 13 comprises at least two screw holes, and a plurality of screw holes are arranged in a straight line; the plurality of threaded holes in the C-shaped set of threaded holes 12 are arranged in a C-shape.
