Abstract
The utility model relates to an axially regulating device for a roller of a rolling mill, which adopts that a transmission worm screw (10) drives an eccentric shaft (6) with a worm wheel. The movement of the eccentric shaft (6) vertical to the axial direction of a roller can be decomposed, through slide blocks on both ends of the eccentric shaft (6) slide in the lining on the wall of a fixed sleeve (3); the movement along the axial direction of the roller can be transferred to a sliding sleeve (1) sliding in the fixed sleeve (3) through a shaft sleeve (4) inlaid on the wall of the sliding sleeve (1); the sliding sleeve (1) can drive a locating bearing, causing that the roller does axial movement. The utility model is in self-locking transmission and has no looseness, simple adjusting, facility, quick response, short stress line, larger stiffness and small size. The utility model is particularly suitable for various miniature rolling mills.
Description
The utility model relates to a kind of adjusting device that moves axially of rolling mill roll, is specially adapted to bar milk.
At present, the roll axial-adjustment unit that particularly generally adopts on the bar milk of milling train at home mainly contains the bolt adjustment type roll axial-adjustment unit that the GY type short stress path rolling mill of University of Science ﹠ Technology, Beijing is adopted; The major diameter screw thread shell type adjusting device by female fully locking of the SY type milling train of Beijing metallurgical equipment research institute; Use and have in the world the axial adjusting device of " red circle " milling train of the Italian Pomini company of extensive report at home, it is to be linked to be whole helical gear by one of worm-drive and thread bush, thread bush is rotated carry out axial adjustment; And German KruPP company prestressed rolling mill roll axial-adjustment unit, it is to shake the moving a pair of eccentric shaft of cornice by screw rod, drives thrust bearing by sliding sleeve again and moves and carry out axial adjustment.Find to exist many problems in this several adjusting devices use in the past.Mainly be that device is difficult for locking, often loosening, and wearing clearance appears after long-term the use, cause the roll axial float; The axial stress line length, stressed member is more, and axial rigidity is little; Volume is big, and accommodation is little; The adjustment process complexity that has, low-response, dumb.
The purpose of this utility model is intended to make improvements according to above-mentioned problems of the prior art, to obtain a kind of new adjusting device, reliably self-locking, not loosening, can eliminate wearing clearance to prevent that roll mandrel is to play, and the axial stress line is short, rigidity is big, and volume is little, and accommodation is big, adjustment process is simple, flexible, response is fast, to satisfy modern milling train for the high-level demand of roll axial-adjustment unit.
For achieving the above object, the technical solution that the utility model proposes mainly is to adopt the eccentric shaft of transmission worm screw rotating band worm gear, and eccentric shaft drives sliding sleeve, and sliding sleeve drives thrust bearing axially moves roll.
Accompanying drawing 1 is depicted as the utility model roll axial section.
Accompanying drawing 2 is depicted as the utility model vertical roller axial section.
Below with reference to Figure of description and embodiment the utility model is done detailed description: as shown in Figure 1 and Figure 2, the bearing block lengthening of the journal bearing of roller neck is made fixed cover (3), the sliding sleeve (1) that is enclosed within the roller neck shaft washer can endwisely slip along roll in fixed cover (3), on sliding sleeve (1) inwall, be shaped on screw thread and a threaded ring (2) is housed, the outer ring of turning in it and sliding sleeve (1) one end thrust bearing clamps, and sliding sleeve (1) is connected with bearing outer ring is fastening.Correspondence has corresponding two through holes respectively on the sliding sleeve (1) of threaded ring (2) opposite side and fixed cover (3) wall, studs with axle sleeve (4) in sliding sleeve (1) hole, studs with lining (5) in fixed cover (3) hole.One eccentric shaft (6) vertical roller axle is contained in two axle sleeves (4), it is thick smooth shaft in axle sleeve (4), its two ends are eccentric thin axle (7) outside sliding sleeve (1), be with the slide block (8) that in lining (5), slides on the thin axle (7), it is clipped in two thick smooth shaft interludes and is made into worm gear, this worm gear is meshed with a transmission worm screw (10) in a worm bracket (9), the spiral part both sides of transmission worm screw (10) are smooth shaft, be contained on two sliding bearings on the screw rod frame (9), worm bracket (9) is connected by key (16) in the middle of being clipped in two axle sleeves (4).In the end of fixed cover (3) protective sleeve (11) is housed, dust cap (12) is housed on the protective sleeve (11).
On sliding sleeve (1) outer wall, have an axial pass trough (13), outside groove, on the corresponding fixed cover (3) a radial column pin-and-hole (14) is arranged, pin is housed, in the hole so that sliding sleeve 1 does not rotate.Being positioned on sliding sleeve (1) inner eccentric shaft (6) two side portions at each axle sleeve respectively has a screw (15), and its head withstands on the threaded ring (2), to eliminate wearing clearance.Slide block (8) in the lining of making by bronze (5), do perpendicular to eccentric shaft to slip, transmission worm screw (10) is provided with perpendicular to eccentric shaft (6), its section of being exposed at dust cap (12) outside is polygon, is convenient to rotate transmission worm screw (10).Protective sleeve (11) can cover column pin hole (14), comes out to prevent pin, and protective sleeve (11) is screwed on fixed cover (3), between it and fixed cover (3) and the dust cap (12) Mi Quan is arranged all.Whole adjusting device is designed to biasing, to reserve the dismounting space of axial restraint screw, makes the roll mounting or dismounting convenient.
When rotating transmission worm screw (10) and drive eccentric shaft (6) rotation, the eccentric thin axle (7) at its two ends is just done eccentric rotary, since be enclosed within slide block (8) on the eccentric thin axle (7) can only in lining (5), do perpendicular to roll mandrel to eccentric shaft to slip, and lining (5) is set in the fixed cover (3), thus eccentric rotary cause eccentric shaft (6) by axle sleeve (4) drive sliding sleeve (1) in fixed cover (3), do roll to move.
Compared with prior art, the utlity model has following characteristics, worm and wormwheel self-locking transmission, reliable and stable, not loosening, can steplessly adjust, adjustment process is simple; Directly adjust roll, response rapidly, flexibly during adjustment; Stressed member is few, and the axial stress line is short, rigidity is big; Can eliminate wearing clearance, make it can not cause the roll axial float because of long-term the use; Volume is little, applicable to various milling trains bar milk particularly.
