Embodiment Construction
[0012] like image 3 As shown, a main drive connecting shaft for a three-roll continuous rolling mill is to connect the movable spline shaft 4-1 and the inner spline sleeve 4-3 with a flange 4-4 to form a sliding assembly. The fixed spline shaft 4-5 is arranged inside, and the spring 4-2 is installed between the fixed spline shaft 4-5 and the sliding assembly, and the spline on the fixed spline shaft completes the function of connecting the shaft to expand and contract. Spring 4-2 is made up of two identical springs, one is installed in the cavity of movable spline shaft 4-1, and the other is installed on the fixed spline shaft 4-5, and spacer ring 4-5 is arranged between two springs. 8. Play a supporting role. Add supporting studs 4-7 at the working position of the connecting shaft, and the supporting studs will fix the position of the moving spline shaft in the working position of the connecting shaft, so as to ensure that the connecting shaft will not come out when it is r...
