The invention relates to the technical field of driving speed reduction, in particular to an axle-sticking running driving speed reducer of a large-axle-load self-propelled metallurgical vehicle with the axle load reaching 40 tons or above, and discloses an axle-sticking running driving speed reducer of a large-axle-load self-propelled metallurgical vehicle. The transmission system is of a two-stage gear reduction structure, and an input gear shaft of the transmission system is installed in first bearing holes of a lower box body and an upper box body through bearings; the input gear shaft is meshed with the first-stage large gear; the first-stage large gear is connected to the second-stage gear shaft in a flat key and interference mode. The secondary gear shaft is mounted in second bearing holes of the lower box body and the upper box body through bearings; the secondary gear shaft is meshed with the output bull gear; the output large gear is connected to the driving axle in an interference mode. The axle box is mounted on the driving axle through a bearing; the axle box is connected with the lower box body and the upper box body through a bolt group and a pin shaft; the lower box body and the upper box body are connected into a whole through a bolt set and a double-end stud.
