The supporting traverse of described forward and backward side is provided with coaxial step mounting hole, the outside of described step mounting hole is connected with lower oil sealing mounting plate by connecting lateral plate, on described lower oil sealing mounting plate, offers the lower seal mounting hole coaxial with step mounting hole.
Described upper box is enclosed and is welded by multiple upper cover side plates, the forward and backward side of described upper box is provided with bearing cover, on described bearing cover, offer the upper bearing bracket mounting hole corresponding with step mounting hole on lower box, the outside of described upper bearing bracket mounting hole is connected with upper oil sealing mounting plate by connecting lateral plate, and described upper oil sealing mounting plate is provided with semicircular upper seal mounting hole.
Upper bearing bracket mounting hole and step mounting hole corresponding on described upper box and lower box enclose a complete bearing support mounting hole, and corresponding upper seal mounting hole and lower seal mounting hole enclose a complete seal mounting hole.Described upper box and lower box are bolted.
Advantage of the present invention and beneficial effect are:
1. bore hole quantity of the present utility model significantly reduces, and has reduced manufacturing procedure.
2. the utility model is owing to having cancelled forging crossbeam, and the weight of casing significantly reduces, and the riser after thickening just no longer needs the reinforcing plate structure of original gear case, in having saved material, has also reduced welding process like this, has shortened the manufacturing cycle.
3. the utility model has reduced the quantity of structural member, to reduce welding difficulty and to reduce workload.
4. the utility model has adopted module design, has improved design efficiency, has reduced design error.
