Abstract

The utility model discloses a front-back double roller damping bearing support of a hot-rolling plate rough mill. A bearing assembled with a roller is mounted in a bearing sheath taking the shape of an octagonal prism; a bearing blank cover and a bearing transparent cover, mounted at two ends of the bearing sheath in a matched manner, are fixedly connected with the bearing sheath through bolts, so as to form an octagonal bearing support; a fabric neoprene bearing support cushion is sleeved outside the octagonal bearing support; two sides walls of the bearing support cushion are matched with symmetrical vertical outer walls of the octagonal bearing support; and notches matched with the roller shaft are reserved on the front and back walls of the octagonal bearing support, and seal seat cushions are arranged below the notches. Two octagonal bearing supports mounted with bearing support cushions are mounted in concave holes of a double roller bearing base, and the concave holes are matched with the bearing cushions in shape; a pressure plate is mounted on the double roller bearing base between the two octagonal bearing supports through a bolt; and two slopes at two ends of the pressure plate are matched with the corresponding inclined outer walls of the octagonal bearing supports. The damping bearing support can flexibly fix the bearing supports, reduce rigid shock and shake, protect bearing, realize reliable positioning and convenient disassembly and assembly, and prolong the service life of the bearings.

Description

Duplex roller damping bearing seat before and after the hot rolled plate roughing mill

Technical field

The utility model belongs to the improvement of steel rolling mill's hot rolled plate roughing mill front and back duplex roller bearing holder structure, particularly hot rolled plate roughing mill front and back duplex roller damping bearing seat.

Background technology

The structure of the hot rolled plate roughing mill front and back duplex roller axle bearing that steel rolling mill is relatively more commonly used at present, the rigid unitary bearing block forms that adopt more, steel billet produces powerful shock loading to it when steel rolling, often cause the damage of the loosening and bearing of bearing block set bolt, change bearing during maintenance and need integral disassembly, assembly, often cause maintenance overtime.

Summary of the invention

The purpose of this utility model is to provide a kind of hot rolled plate roughing mill front and back duplex roller damping bearing seat, makes the bearing block flexible fastening, can reduce rigid shock and vibrations, the protection bearing, and the location is reliable, is convenient to dismounting, improves the service life of bearing.

The purpose of this utility model is achieved in that a kind of hot rolled plate roughing mill front and back duplex roller damping bearing seat, profile is in the bearing sheath of octagonal prism the bearing that is equipped with roller to be installed, cooperate the bearing stifle be installed in bearing sheath two ends and bearing air cover by bolt and the bearing sheath formation octagonal bearing block that fixes as one, fabric neoprene bearing seat cushion at the outside suit of octagonal bearing block, the upright outer wall of the two side of its bottom bracket pad and octagonal bearing block symmetry matches, the front and rear wall of octagonal bearing block is reserved the breach that matches with the roller roll shaft, breach is following for sealing seat cushion, two octagonal bearing blocks that the bearing seat cushion is housed are installed in the duplex roller bearing pedestal shrinkage pool that matches with bearing cushion profile, by bolt pressing plate is installed on the duplex roller bearing pedestal between two octagonal bearing blocks, pressing plate matches with the inclination outer wall of corresponding octagonal bearing block respectively by the inclined-plane at its two ends.

The utility model is owing to be installed with octagonal bearing sheath on duplex roller bearings at both ends, the saturating lid and the stifle that are positioned at bearing sheath two ends fix as one by bolt and bearing sheath, constitutes the octagonal bearing block.Fabric neoprene bearing seat cushion at the outside suit of octagonal bearing block, and in the shrinkage pool that matches of the duplex bearing pedestal of packing into together, fix with pressing plate.The impact and the vibrations that at work can the damping steel billet cause, the location is reliable and be convenient to the dismounting of roller.The utility model makes the bearing block flexible fastening, has reduced rigid shock and vibrations, the protection bearing, and the location is reliable, is convenient to dismounting, has improved the service life of bearing.

The specific embodiment

Duplex roller damping bearing seat before and after a kind of hot rolled plate roughing mill, as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Figure 9, profile is in the bearing sheath 2 of octagonal prism the bearing 1 that is equipped with roller 8 to be installed, cooperate the bearing stifle 4 be installed in bearing sheath 2 two ends and bearing air cover 3 by bolt and the bearing sheath 2 formation octagonal bearing block that fixes as one, fabric neoprene bearing seat cushion 5 at the outside suit of octagonal bearing block, the upright outer wall of the two side of its bottom bracket pad 5 and octagonal bearing block symmetry matches, the front and rear wall of octagonal bearing block is reserved the breach that matches with roller 8 roll shafts, breach is following for sealing seat cushion, two octagonal bearing blocks that bearing seat cushion 5 is housed are installed in duplex roller bearing pedestal 9 shrinkage pools that match with bearing seat cushion 5 profiles, by bolt pressing plate 10 is installed on the duplex roller bearing pedestal 9 between two octagonal bearing blocks, pressing plate 10 matches with the inclination outer wall of corresponding octagonal bearing block respectively by the inclined-plane at its two ends.Make the flexible fastening of the radial and axial equal energy of roller bearing, under the impact of big radial load and less axial force, bearing 1 suffered rigid shock reduces, and avoids the bearing premature failure.The locating convex block 7 of symmetry is being set on the bottom surface of duplex roller bearing pedestal 9, and locating convex block 7 matches with groove on the roller-way support 6, and duplex roller bearing pedestal 9 is fixed on the roller-way support 6 by bolt.Because front, rear, left and right all are being provided with locating convex block 7 on duplex roller bearing pedestal 9 bottom surfaces, duplex roller bearing pedestal 9 fixes as one by foundation bolt and roller-way support 6, has avoided impacting the moving phenomenon of the bolt bolt that causes.Match with the supporting surface of roller-way support 6 in the bottom surface of bearing seat cushion 5.
