For example, Japanese Unexamined Patent Application Publication No. Sho 6-96 mentioned in the section of the prior art.
In the 2-156007 publication, since the hollow roll shaft is extended to the outer periphery of the roll bearing on the outer periphery of the solid roll shaft, the roll neck diameter of the solid roll shaft becomes small,
The allowable rolling reaction force in the horizontal direction tends to be smaller than in the case of an integral roll having the same size. In addition, since there is a roll width adjusting device outside the roll bearing, the total length of the roll is long, and further, the axial length of the hollow roll shaft that requires highly accurate machining on both the inner surface and the outer surface is long, which increases the equipment cost. .

Also, in the Japanese Patent Laid-Open No. 61-17310, the hollow roll shaft is provided on the outer periphery of the solid roll shaft to the outside of the roll bearing. In comparison with the above case, the allowable rolling reaction force in the horizontal direction tends to be smaller, and the axial length of the hollow roll shaft, which requires high-precision machining on both the inner surface and the outer surface, becomes longer, resulting in higher equipment costs.

Further, in the one disclosed in Japanese Patent Laid-Open No. 62-176604, since the roll width adjusting screw is provided between the roll sleeves, the minimum roll width that can be adjusted tends to be large, and the web height is low.

Also, in the case of Japanese Unexamined Patent Publication No. 61-9905, since the roll width adjusting device is provided between the roll sleeves, the minimum roll width that can be adjusted tends to be large, and the material to be rolled is large. Dimensional restrictions become large, and the fitting between the roll sleeve and the roll shaft is released by high-pressure fluid when adjusting the roll width, which requires a high-pressure fluid generator and its introduction path, which increases equipment costs. In addition, the torque that can be transmitted between the roll sleeve and the roll shaft is limited to the range in which the inner diameter of the roll sleeve can be expanded by the high-pressure fluid, and the restriction on the rolling torque tends to increase.

[Function] Since the roll width adjusting screw is provided in the vicinity of the fitting portion between the roll shaft and the hollow shaft, it is not necessary to extend the hollow shaft to the outside of the roll bearing of the roll shaft, so that the inner roll shaft has the same shaft diameter. Since it can be taken like an integrated roll of the same size, the allowable rolling reaction force in the horizontal direction is the same as that of an integrated roll of the same size. In addition, the total length of the roll is the same as that of an integral roll with the same size, and the hollow shaft that requires highly accurate machining on both the inner and outer surfaces has a short shaft length, so the equipment cost is low.

Further, since the roll width adjusting screw is provided in the vicinity of the fitting portion between the roll shaft and the hollow shaft, there is no complicated roll width adjusting device between the hollow shafts and between the hollow shaft and the roll bearing. There are few restrictions on the minimum roll width and the maximum roll width to be obtained, and as a result, the roll width adjustment amount can be made large.

Further, since the roll shaft and the hollow shaft are connected by a slide key and the rolling torque is transmitted by the slide key, it is necessary to generate a high-pressure fluid between the roll shaft and the hollow shaft when adjusting the roll width. In addition, there is no need for an expensive high-pressure fluid generator, and the cost is low, and the restriction on rolling torque is small.

Normally, rolling is performed with the clutch 11 being discontinuous. The horizontal rolling reaction force passes from the roll sleeves 5a and 5b through the hollow shafts 3a and 3b, and through the fitting surfaces of the hollow shafts 3a and 3b and the roll shaft 1, from the roll shaft 1 to the roll bearing 2a,
2b, and further transmitted to the bearing boxes 9a, 9b. As for the axial rolling reaction force, the horizontal rolling reaction force passes from the roll sleeves 5a and 5b through the hollow shafts 3a and 3b, and is passed through the screw between the hollow shafts 3a and 3b and the screw sleeves 7a and 7b.
a, 7b, the threaded sleeves 7a, 7b and the axial contact surfaces of the roll shaft 1 are passed through the roll shaft 1 to the roll bearing 2
c, transmitted to the bearing box 9a. The rolling torque is transmitted from the roll shaft 1 to the hollow shafts 3a and 3b and the roll sleeves 5a and 5b through the slide keys 4a and 4b between the roll shaft 1 and the hollow shafts 3a and 3b. At this time, the screw sleeves 7a and 7b are pressed against the axial contact surface of the roll shaft 1 by the axial rolling reaction force, rotate in synchronization with the roll shaft 1 by the frictional force, and the hollow shaft 3a. , 3b are also rotated in synchronization with the roll shaft 1 by the slide keys 4a, 4b, so that the screw sleeves 7a, 7b and the hollow shafts 3a, 3b are rotated in synchronization with each other in the rotation direction. Since there is no relative speed difference, the roll width is kept constant. Further, the rotary shaft 12 rotates in synchronization with the screw sleeves 7a and 7b via the gears 13a and 13b and the pinions 8a and 8b, but the rotation is transmitted to the rotary drive device 10 because the clutch 11 is in an intermittent state. The roll width is kept constant.

When adjusting the roll width, the clutch 11 is engaged, the rotary drive unit 10 is activated to rotate the rotary shaft 12, and the screw sleeves 7a and 7b are rotated via the gears 13a and 13b and the pinions 8a and 8b. At this time, since no rolling is performed, reaction force in the axial rolling is not generated,
Therefore, since the screw sleeves 7a and 7b are not restrained by the roll shaft 1, the screw sleeves 7a and 7b rotate independently of the roll shaft 1 independently. Also, the hollow shafts 3a, 3b
Since it is connected to the roll shaft 1 by the slide keys 4a and 4b, it does not rotate independently of the roll shaft 1. As a result, the screw sleeves 7a and 7b are attached to the hollow shaft 3
The hollow shafts 3a and 3b are rotated with a relative speed difference, and a screw is formed between the hollow shafts 3a and 3b and the screw sleeves 7a and 7b. It moves in the axial direction with respect to 7a and 7b. Since the screw sleeves 7a and 7b are embedded in the roll shaft 1 and cannot move in the axial direction with respect to the roll shaft 1, the hollow shaft 3
a and 3b move in the axial direction with respect to the roll shaft 1. Since the screws engraved on the hollow shafts 3a and 3b are right-handed screws and left-handed screws having an equal pitch, respectively, the roll width can be adjusted by evenly distributing them to the center of the line.

In the embodiment shown in FIG. 1, the screw sleeve 7
Although an example is shown in which a and 7b are embedded in the roll shaft 1 so as to loosen both in the rotational direction and in the axial direction, the screw sleeves 7a and 7b are attached to the roll shaft 1 to the screw sleeve 7 as shown in FIG.
a and 7b are tightly fitted so as not to loosen, a passage for introducing high pressure fluid is provided between the roll shaft 1 and the screw sleeves 7a and 7b, and normally, the roll shaft 1 and the screw sleeves 7a and 7b are provided.
The threaded sleeves 7a and 7b are locked by the roll shaft 1
When the roll width is adjusted, the high pressure fluid is introduced into the high pressure fluid introduction passage to expand the inner diameters of the sleeves 7a and 7b, so that the roll shaft 1 and the screw sleeves 7a and 7b are fitted together. Release the screw sleeve 7a,
The configuration may be such that 7b is freely rotatable with respect to the roll shaft 1. At this time, the roll shaft 1 and the screw sleeve 7a,
The fitting between 7b may be a tightening margin that can be transmitted with a torque corresponding to the moment of inertia of the screw sleeves 7a and 7b, and does not require a torque for transmitting rolling torque, so that the pressure of the high pressure fluid is relatively high. It can be low-pressure and does not require a special high-pressure generator, so the cost is low. Further, the rolling torque is transmitted from the roll shaft 1 to the hollow shafts 3a and 3b and the roll sleeves 5a and 5b through the sliding keys 4a and 4b between the roll shaft 1 and the hollow shafts 3a and 3b. It goes without saying that it has a high allowable rolling torque without being affected by the fitting between the No. 1 and the screw sleeves 7a and 7b.
