摘要： PURPOSE:To ensure caused oil film pressure to surely prevent seizure, by providing an oil pocket at the rear part of the loaded surface of a bearing member and opening oil supply holes into the ends of the oil pocket at the loaded surface. CONSTITUTION:A shell 4 is provided on the inside surface of a bearing member 3. An oil pocket 5 for assuring a prescribed quantity of supplied oil is provided inside the rear part of a loaded surface 3a, on which oil film pressure is caused. A plurality of oil supply holes 6 opened at a regular spacing in the axial direction and extending into the ends 5a of the oil pocket 5 at the loaded surface 3a are connected to an oil tank 9 through pipes, a cooler 7 and an oil pump 8. Oil controlled to a prescribed temperature is supplied into the gap between the shell 4 and a sleeve 2 on a rotary shaft 1 through the oil supply holes 6 and the oil pocket 5 and revolved together with the rotary shaft 1 so that the oil is brought to the loaded surface 3a. Since the gap between the sleeve 2 and the shell 4 becomes smaller, the oil film pressure is caused.

摘要： PURPOSE:To freely incline an upper roll group during the operation of leveling and to contrive miniaturization of an apparatus for rolling reduction by adding an inclining moment of the upper roll group by an exclusive inclining device provided to a hausing. CONSTITUTION:On the working side and the driving side of a leveler housing 6, inclining devices 16a, 16b are provided to advance and a retreat cylinder rods 15a, 15b in the progressing direction Z of a sheet 1. Further, at the time of inclining the upper roll group 4, for adjusting an intermesh during the leveling work, a fluid pressur is fed to a prescribed hydraulic cylinder of inclining device to incline. At this time, the rolling reduction force of the apparatus 7a, 7b of rolling reduction is enough only with the rolling reduction force of leveling. Therefore, the upper roll group 4 is freely inclined during the operation of leveling and the apparatus for rolling reduction is miniaturized.

摘要： PURPOSE:To straighten plates in a wide thickness range using one leveler by facing small straightening roll units to large straightening rolls arranged at vertically zigzag positions and setting a means to move the small roll unit up and down. CONSTITUTION:Large straightening rolls 2a, 2a' are arranged zigzag in the up and down sides of the passing direction Z of a plate 1 and small straightening roll units 12, 12' are arranged to face the large rolls 2a, 2a'. The units 12, 12' consist of small straightening rolls 10, 10' and backup rolls 11a-11b' respectively and are moved up and down separately by a lifter 15. Both the large and small roll groups are used to straighten a thin plate of 4.5-20mm thickness and the large roll group is sued to straighten a thick plate of 20-50mm thickness with the small roll groups inactivated. Therefore, plates in a wide thickness range are straightened by the one leveler, so that both an equipment cost and an installation space are reduced.

摘要： PURPOSE:To improve considerably the capacity for leveling a sheet material with simple modification of the conventional roller leveler in a roller leveler which passes the sheet material between upper and lower leveling roll groups by providing a pinch roll group before said roll groups on the sheet feed side. CONSTITUTION:The sheet material 3 having a defective shape is fed between the upper and lower rolls of the leveling roller group A constituted of the upper and lower leveling rolls 1, 1..., 2, 2..., by which the shape is corrected. The pinch roll group B consisting of the roll pairs of upper and lower pinch rolls 4, 5 is provided before the roll group A on the material 3 feed side. The group B grasps under the pressure the material 3 between the rolls 4 and 5 and transfers the material into a direction X so as to feed the material into the group A. The internal stress distribution of the defective shape material having edge waves is thus increased and the stress distribution is created particularly in the top end of the sheet as well. The satisfactory leveling effect is thus obtd.

摘要： PURPOSE:To prevent the generation of seizure and cracks at a fitting part by providing ceramic coating to the outer circumferential surface of the taper neck- part of a roll and the inner circumferential surface of a sleeve, in a oil-film bearing constituted of a roll journal-part and a bearing box. CONSTITUTION:A taper sleeve 3 is fitted to the outer circumferential surface 2a of a taper neck-part 2 of roll 1, and is tightly fastened and fixed to the neck- part 2 by a sleeve holder 9 and a lock nut 10, and a shell 5 surrounding the outer circumference of sleeve 3 is internally attached to a bearing 4. Next, lubrication-oil supplying holes and oil feeding ports are formed at the box 4 and the shell 5 respectively, to form an oil-film bearing between the sleeve 3 and the shell 5. At that time, ceramic coating is provided to the outer circumferential surface 2a of neck part 2 and the inner circumferential surface 3a of sleeve 3. In this way, fretting phenomena at the fitting parts of the outer circumferential surface of taper neck-part and the inner circumferential surface of taper sleeve are eliminated, thereby preventing the generation of seizure and cracks at the fitting part.

摘要： PURPOSE:To produce a bearing for a great material with an Al alloy, by forming a plating layer consisting of a soft metal simple substance on the inside circumferential face of the backing metal of the bearing and laminating an Al alloy layer on this plating layer and joining these layers with press-contacting. CONSTITUTION:After the inside circumference of a backing metal 1 is subjected to surface treatments such as degreasing and cleaning, a plating layer (intermediate layer ) 2 consisting of a soft metal simple substance such as Sn and Cu is formed. Next, an Al alloy layer 3 is formed on the inside circumferential face of the bakcing metal by the centrifugal casting method or the like. In this case, lower one of melting points of the Al alloy layer 3 and the intermediate layer 2 is used as the reference temperature to bring rolls 4 into press-contact with the backing metal 1 and the layer 3, and they are adhered closely completely. After the Al alloy layer 3 is brought into press-contact with the backing metal 1, the layer 3 is cut and finished, thus completing an alloy bearing.

摘要： PURPOSE:To straighten plates being in the range from thin to thick using only one leveler by separating upper and lower work roll groups into a fixed roll group and an adjustment work roll group vertically movable and setting roll shift mechanisms. CONSTITUTION:An upper work roll group for a plate 1 to be straightened consists of an upper fixed work roll group 12a and an upper adjustment work roll group 12b vertically movable by lifting mechanisms 20 and 21. The structure of lower roll groups is the same as that of the upper roll groups. A lower roll frame 15' is provided with shift and adjustment mechanism 31a, 32-34. In that structure, a thin plate is straightened by using the upper and lower adjustment work roll groups and the upper and lower fixed work roll groups and by adjusting roll positions by the shift mechanisms. A thick plate is straightened by using the fixed work roll groups whose positions are properly adjusted by the shift mechanisms and by inactivating the adjustment work roll groups, so that the one leveler straightens plates being in the range from thin to thick.

摘要： PURPOSE:To straighten the strain of a strip plate and to elevate the accuracy in thickness by giving a rolling function to at least one pair of the upper and lower rolls and by widening the straightening limit thereof in the roller leveller arranging multiple rolls to perform a shape straightening with pressing a strip plate from the up and down. CONSTITUTION:A strip plate M is flattened with being bent in zigzags by upper and lower roll groups 5, 6 and with removing an inner part stress. A rolling function is given by a rolling reduction mechanism 10 by opposing the at least one pair of upper and lower rollers 9a, 9b among the roller groups 5, 6. The shape accuracy is improved with giving an elongation to the strip plate M by a rolling and the residual stress is removed with giving a bend by other levelling rolls. By giving this rolling the straightening limit of the strip plate is enlarged.
