In the hot-strip production process, all be to use the transportation of roller-way usually with steel.At present, the hot-strip rollgang of prior art generally comprises base, roller, roll shaft, shaft shoulder plate, left shaft holder, the right bearing seat, left side self-aligning bearing, right self-aligning bearing, bearing plate, end cap, logical lid, shaft coupling and frequency control motor, roller is enclosed within outside the roll shaft, and be connected with roll shaft by shaft shoulder plate, left shaft holder and right bearing seat are enclosed within the two ends, the left and right sides of roll shaft respectively, and be rotatably connected by left self-aligning bearing and right self-aligning bearing and roll shaft respectively, left shaft holder and right bearing seat are all by being bolted on the base, bearing plate is close on the wall of a left self-aligning bearing inner ring left side, and be connected with the roll shaft left end, end cap is close on the wall of a left self-aligning bearing outer ring left side, and be connected with the left shaft holder left end, logical lid is enclosed within on the roll shaft right-hand member, its left end is close on the right wall of right self-aligning bearing outer ring, and be connected with the right bearing seat, frequency control motor is connected with the roll shaft right-hand member by shaft coupling.Though the hot-strip rollgang of said structure can make roller have aligning preferably, but also there is a weak point in it in actual application: well-known, roller in the hot-strip rollgang should bear high temperature, bear the load of band steel again, therefore its condition of work is very abominable, work long hours and be easy to wear damage, and when its damage needs to change, the staff needs earlier end cap and bearing plate to be pulled down, and then after pulling down left shaft holder and bolt that base is connected, could unload from left shaft holder by knocking the roll shaft that left shaft holder will be connected with roller, after replacing was finished, the staff need install to the new roll shaft that is connected with roller on the left shaft holder again, and then left shaft holder is fixed on the base, load onto bearing plate and end cap at last successively, so roll change work bothers very.
The utility model content
The technical problems to be solved in the utility model is, a kind of roll shaft easy accessibility is provided, thereby can make the roll change work simple hot-strip rollgang that becomes.
For solving the problems of the technologies described above, the utility model provides a kind of hot-strip rollgang of following structure: comprise base, roller, roll shaft, shaft shoulder plate, left shaft holder, the right bearing seat, self-aligning bearing, bearing plate, end cap, logical lid, shaft coupling and frequency control motor, roller is enclosed within outside the roll shaft, and be connected with roll shaft by shaft shoulder plate, left shaft holder and right bearing seat are all by being bolted on the base, the right bearing cover for seat is at the roll shaft right-hand member, and be rotatably connected by self-aligning bearing and roll shaft, logical lid is enclosed within on the roll shaft right-hand member, its left end is close on the right wall of self-aligning bearing outer ring, and be connected with the right bearing seat, frequency control motor is connected with the roll shaft right-hand member by shaft coupling, left shaft holder is enclosed within the roll shaft left end, wherein, the cylinder roller bearing that also comprises a NU type, left shaft holder is rotatably connected by cylinder roller bearing and roll shaft, bearing plate is close on the wall of a cylinder roller bearing inner ring left side, and be connected with the roll shaft left end, end cap is close on the wall of a left side, cylinder roller bearing outer ring, and be connected with the left shaft holder left end, the external diameter of bearing plate is less than cylinder roller bearing inner ring external diameter, and the shaft hole diameter of left shaft holder is greater than cylinder roller bearing inner ring external diameter.
Hot-strip rollgang described in the utility model, wherein, end cap is provided with left oil filler point, and logical covering is provided with right oil filler point.
After adopting said structure, compared with prior art, the utlity model has following advantage: because the utility model hot-strip rollgang has adopted inner ring and outer ring separable between left shaft holder and roll shaft, and inner ring does not have the NU type cylinder roller bearing of rib, and the external diameter of bearing plate is less than cylinder roller bearing inner ring external diameter, the shaft hole diameter of left shaft holder is greater than cylinder roller bearing inner ring external diameter, therefore, when the roller damage needs to change, the staff need not end cap and bearing plate are pulled down, only need the bolt that left shaft holder is connected with base is pulled down, then left shaft holder is removed left, can make in succession cylinder roller bearing inner ring and bearing plate of the roll shaft that is connected with roller pass in the axis hole of left shaft holder and separate with left shaft holder, after pulling down roll shaft, the staff can pull down bearing plate and cylinder roller bearing inner ring easily from roll shaft, and then be connected on the new roll shaft that is connected with roller, at last, the staff only need in succession the new roll shaft of cylinder roller bearing inner ring and bearing plate from new clothes to the left shaft holder on, and by bolt left shaft holder is fixed on the base and gets final product, and, in the process of above-mentioned replacing roller, because the inner ring and the frictional force between the ball of cylinder roller bearing are very little, therefore, the staff can separate left shaft holder and assemble easily with roll shaft, and need not to use very big strength, therefore, the utility model hot-strip rollgang greatly facilitates the dismounting of roll shaft, makes roll change work become simple.
Being located at the left oil filler point on the end cap in the utility model hot-strip rollgang and being located at the effect of leading to the right oil filler point that covers is that the staff can directly need not to pull down end cap and Tong Gai by left oil filler point and right oil filler point to the oiling of roll shaft two ends, thereby can make things convenient for the carrying out of oiling work greatly.
