Definitions

  • ABSTRACT An apparatus for axially adjusting a work roll in a rolling mill.
  • the apparatus includes an annular piston cylinder assembly surrounding one end of the work roll.
  • the cylinder is fixed relative to the roll chock and the piston, which is hydraulically actuated for reciprocal adjustment in opposite directions parallel to the rotational axis of the work roll, is connected through a thrust bearing assembly to the roll sleeve, the latter being fixed relative to the work roll and being both rotationally journalled in and movable axially relative to the roll chock.
  • the adjustment mechanism of the present invention is hydraulically rather than mechanically actuated. This eliminates interfaces between gears, screw threads, levers, etc., and the resulting backlash which has consistently plagued the mechanically actuated prior art mechanisms.
  • Other objects of the present invention include the provision of a hydrau lically actuated mechanism which can be remotely adjusted from a central control station, and which responds instantaneously, thereby permitting precise axial adjustments to be made to the rolls during the rolling operation.
  • a still further object of the present invention is the provision of an improvedaxial roll adjustment mechanims which is simple in design, witha minimum number of operating components, thereby facilitating both installation and maintenance of the roll bearings into which the adjustment mechanism is incorporated.
  • the hearing assembly includes a roll chock 12 which is conventionally adapted to be mounted in a roll housing.
  • the chock is lined with a bushing 14 which provides a bearing surface as at 16 for the roll sleeve 18, the latter being tightly seated on and keyed against rotation relative to the truncated conical neck portion 20 of a work roll 22.
  • the work roll 22 is further provided with cylindrical end extensions 24 and 26 separated by a reduced diameter section forming a wide groove 28.
  • An annular cylinder 30, which may conveniently comprise as assembly of two mating sections 30a and 30b, surrounds the roll end and is both held together and affixed to the end of chock 12 by means of bolts indicated typically at 32.
  • the cylinder 30 defines a cir cular chamber having an inner wall 34 and oppositely disposed front and rear walls 36 and 38.
  • a circular piston 40 protrudes radially into the cylinder chamber. The thickness of piston 40 is less thanthe distance between the front and rear chamber walls 36 and 38, thereby creating annular spaces 42 and 44 therebetween.
  • Piston 40 is further provided with a somewhat cylindrical base 46 which is carried on one end of an intermediate sleeve connector 48.
  • the connector has a groove 50 into which the piston base 46 is seated.
  • the piston base is held against a shoulder 52 at one end of the groove 50 by means of a lock nut 54 which is threaded on the sleeve connector as at 56.
  • sleeve connector 48 is slidably re- .ceived as at 59 in the chock l2 and is interiorly notched as at 58 to receive the outer race 60a of a thrust bearing assembly generally indicated at 60.
  • the outer race is held against rotation relative to the sleeve connector 48 by means of a pin 62, and is retained in notch 58 by a keeper ring 64 and bolts 66.
  • the inner bearing race 60b is seated on a lip 68 which extends axially from the end of roll sleeve 18. The inner race is held in place initially against shoulder 67 by means of a snap ring 69.
  • An exteriorly threaded split ring 70 is seated in the groove 28 on the roll end and is temporarily held together by a coiled spring 72.
  • a nut member 74 is threaded onto the split ring 70 and when tightened, its forward end 76 acts through the inner thrust bearing race 60b to axially seat the roll sleeve 18 on the truncated conical neck portion 20 of the roll 22.
  • passageways 78 and 80 lead inwardly from the exterior of cylinder 30 to the annular chamber containing piston 40.
  • the interior end of the passageway 78 tenninates in an opening 78' in communication with annular space 42, and likewise the interior end of passageway 80 terminates in an opening 80' in communication with annular space 44.
  • the exterior ends of the passageways 78 and 80 are threaded as at 81 for connection to a hydraulic system which can be of conventionally known design.
  • the invention operates in the following manner:
  • the work roll is axially fixed by maintaining a zero flow condition in passageways 78 and 80.
  • a linear transducer 84 is preferably mounted on and extends through the bearing end cap 86 to provide a means of precisely and remotely measuring the axial adjustments being imparted to the work roll.
  • apparatus for axially adjusting the work roll comprising: cylinder means supported by and fixed relative to the chock assembly, said cylinder means defining a chamber containing a piston which is reciprocally movable therein in opposite directions parallel to the rotational axis of the work roll, means for introducing hydraulic fluid into said chamber on one side or the other of said piston while simultaneously withdrawing hydraulic fluid from said chamber on the opposite side of said piston, with the result that the piston is reciprocated within said chamber, and intermediate means including a thrust bearing assembly for connecting said piston to the roll sleeve, said intermediate means being effective to transfer the reciprocal movement of said piston to the roll sleeve and the roll to which the sleeve is fixed, while permitting the roll and sleeve to rotate relative to said piston and cylinder.
  • said intermediate means further includes a sleeve member surrounding the said one end of the work roll, one end of said sleeve member being connected to said piston, the other end of said sleeve member being connected to said thrust bearing assembly.
  • said thrust bearing assembly includes inner and outer rela tively rotatable races, the said outer race being affixed to the said other end of said sleeve member, the said inner race being seated in a groove in the roll sleeve, and retaining means rotatable with the work roll for holding said inner race in said groove.
  • said retaining means includes a threaded ring supported by and fixed against axial movement relative to the work roll, and a nut member threaded onto said ring to a tightened position at which said nut member contacts said inner race and exerts a retaining force thereon which holds said inner race in said groove.
