Description
Technical field:
The utility model relates to a kind of parts of steel rolling continuous annealing furnace, refers more particularly to hanging arm roll in a kind of stove.
Background technology:
In metallurgical industrial furnace, metal pipe material, bar adopt hanging arm roll to carry conveying in annealing furnace, and at present, the furnace roller on market is made up of the body of roll, roll neck, spindle nose, and the body of roll, roll neck, spindle nose weld together.Hanging arm roll is in stove, driving part is outside stove, and therefore furnace roller cantilever is very long, and hanging arm roll deadly defect is jib-length and payload, owing to operating under high temperature hostile state, the Rigidity and strength of roll shaft is lower, easily causes roll shaft flexural deformation, and welding seam failure ftractures, very cause the phenomenon of disengaging, whole furnace roller cannot be used, cause the waste of material, add the labour intensity of maintenance cost and workman.
Summary of the invention:
The purpose of this utility model is to provide a kind of rational in infrastructure, is convenient to repair, and can improve work-ing life, reduce hanging arm roll in the stove of production cost.
The purpose of this utility model is achieved in that hanging arm roll in a kind of stove, comprise bearing, roll shaft, bearing assembly, bearing outer end has been fastened by bolts motor reducer, motor reducer cogs to cog with roll shaft and engages, it is characterized in that: roll shaft stove the inner cover has roller shell, and being fixed on roll shaft by stop nut, on roller shell the other end roll shaft, uniform vertical is welded with four preset piecess; Roll shaft stove outer end cover has flange, is provided with snap ring in flange shoulder hole; Described roll shaft is set to tubular shaft, and roll shaft stove the inner is welded with silently, and silently inner side is welded with water pipe fixed block, and water pipe fixed block inner sleeve has water-cooled tube; There is swivel joint described roll shaft stove outer end by Flange joint, is provided with sealing-ring between roll shaft end face and swivel joint; Described water-cooled tube is tightened together by set nut with swivel joint.
Described snap ring inner ring is stuck in the ring groove of roll shaft.
Described set nut is provided with gas thread.
Described preset pieces is stuck in the locating slot of roller shell end face.
Described roller shell cylindrical is provided with V-type groove, and the angle of V-type groove is 140 ° ~ 160 °, and roller shell inside is set to hollow structure.
Described water pipe fixed block is provided with cooling-water duct.
Described stop nut is welded after tightening with roller shell and roll shaft.
The utility model is rational in infrastructure, is convenient to repair, and improves work-ing life, reduces production cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is I enlarged view in Fig. 1;
Fig. 3 is II enlarged view in Fig. 1;
In figure 1, bearing, 2, roll shaft, 3, preset pieces, 4, roller shell, 5, water pipe fixed block, 6, stop nut, 7, silently, 8, water-cooled tube, 9, bearing assembly, 10, motor reducer, 11, flange, 12, snap ring, 13, sealing-ring, 14, set nut, 15, swivel joint.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, hanging arm roll in a kind of stove, comprise bearing 1, roll shaft 2, bearing assembly 9, bearing 1 outer end has been fastened by bolts motor reducer 10, motor reducer 10 cogs to cog with roll shaft 2 and engages, it is characterized in that: roll shaft 2 stove the inner cover has roller shell 4, and is fixed on roll shaft 2 by stop nut 6, and on roller shell 4 the other end roll shaft, uniform vertical is welded with four preset piecess 3; Roll shaft 2 stove outer end cover has flange 11, is provided with snap ring 12 in flange 11 shoulder hole; Described roll shaft 2 is set to tubular shaft, and roll shaft stove the inner is welded with silently 7, and silently inner side is welded with water pipe fixed block 5, and water pipe fixed block inner sleeve has water-cooled tube 8; Described roll shaft 2 stove outer end is connected with swivel joint 15 by flange 11, is provided with sealing-ring 13 between roll shaft 2 end face and swivel joint 15; Described water-cooled tube 8 is tightened together by set nut 14 with swivel joint 15.Described snap ring 12 inner ring is stuck in the ring groove of roll shaft 2.Described set nut 14 is provided with gas thread.Described preset pieces 3 is stuck in the locating slot of roller shell end face.Described roller shell 4 cylindrical is provided with V-type groove, and the angle of V-type groove is 140 ° ~ 160 °, and roller shell 4 inside is set to hollow structure.Described water pipe fixed block 5 is provided with cooling-water duct.Described stop nut 6 is welded after tightening with roller shell 4 and roll shaft 2.
During concrete enforcement, motor reducer is rotated by drive gears action roller shaft, and roll shaft drives roller shell to rotate by preset pieces and stop nut, and several roller-ways form conveying belt, conveying steel pipe in stove.Logical circulating cooling water cooling in roll shaft, controlled cooling model water intake pressure is: 0.4MPa, inflow temperature≤33 °, leaving water temperature(LWT)≤48 °.The utility model in use, difficult drop-off, cracking, long service life, once welding seam failure cracking, whole furnace roller (roll shaft and axle sleeve form furnace roller) also can not be made to use, again can continue after welding to use, the waste of material can not be caused, fall and lacked maintenance cost.
