Definitions

  • a coupling for a mill roll and the like comprises a connector having a coupling bore therein, with the bore having a first surface shaped for close fitting engagement with a neck portion of the roll adjacent one extremity of the coupling engagement therebetween and a second surface shaped for close fitting engagement with the roll neck adjacent the opposite extremity of such engagement and a third surface disposed generally between the first and said second surfaces shaped for an increasingly close fit with the roll neck as the roll neck is increasingly inserted into the connector.
  • the present invention relates to a coupling for mill rolls, and more particularly to a coupling of a character described which is structured to facilitate a quick and reliable coupling of the components thereof for roll changing purposes.
  • the present invention provides means for quickly and reliably aligning the several components of a mill roll coupling arrangement such that a close fit at the ends of the engagement between the coupling and the roll neck are obtained. This results in positive mating of the coupling components.
  • tapering surface configurations together with adequate champfering ensure that liberal clearances are available for insertion of the roll neck into the coupling. Close engagement. is accomplished near the end of the entering operation, as increasingly close clearances guide the roll neck into a quick and reliable coupling.
  • close clearances are provided at parallel roll neck flats for imparting maximum torque to the work roll.
  • I also desirably provide a similar coupling wherein said second surface is formed on a projection sup ported in said connector and insertable into a complementary shaped recess in. said roll neck.
  • I also desirably provide a similar coupling including a roll neck portion shaped for insertion into said coupling bore, said portion including. constant tolerance surfaces for close fitting engagement with said first andsaid second connector surfaces and avarying tolerance portion shaped for increasingly close engagement with said third connector surface.
  • I also desirably provide a similar coupling wherein driving; flats are separated by diametric portions of said third surface, said third surface portions having a conical. configuration.
  • FIG. 1 is a longitudinally sectioned view of one form of mill roll coupling arranged in accordance with the invention
  • FIG. 2 is a cross-sectional view of the coupling as shown in FIG. 1 and taken along reference line IIll thereof;
  • FIG. 3 is another cross-sectional view of the coupling as shown in FIG. 1 and taken along reference line III- III thereof. r
  • the exemplary form of the mill roll coupling 10 shown therein comprises a connector 12 having a coupling bore 14 therein.
  • the coupling bore 14 is arranged for an initial, relatively loose fitting engagement and then a close-tolerance engagement with roll neck 16.
  • the roll neck 16 includes a coupling end portion 18 constructed in accordance with the invention for a surprisingly quick-attack but reliable engagement with the connector 12.
  • the roll neck end portion 18 comprises a pair of driving or torque transmitting flats 20, 22 FIG. 3), which, when inserted into the connector 12 closely engage a complementary pair of driving flats 24, 26 of the connector 12.
  • the torque transmitting flats 20-26 of the roll neck and connector are substantially parallel and are formed with close-fitting tolerances.
  • the connector 12 can be fabricated from a high-grade steel for maximum torque carrying capability.
  • the connector 12 can be provided with replaceable liners (not shown) at its driving flats 24, 26 for engagement with the roll neck flats 20, 22.
  • the remainder of the arcuate surfaces of the coupling end portion 18 of the roll neck 16 desirably are cylindrical at reference characters 40, 42.
  • The'corresponding surfaces of the connector 12 likewise are of complementary cylindrical configuration.
  • the purpose of the conical surfaces 32-38 is the provision of relatively looseor liberal clearances between the coupling end portion 18 of the roll neck and the connector 12 when the roll neck initially is inserted into the coupling bore 14.
  • the tolerances become "tighter until a close coupling fit is attained when the cylindrical portions 40; 42 of the roll neck are inserted into the complementarily shaped portion of the connector 12.
  • This can provide a very close fit adjacent one end of the engagement between the roll neck 16 and the connector 12 without, however, interferring with the initial entry of the roll neck end portion 18 into the connector 12.
  • a quick-attach but reliable engagement between the connector 12 and the roll neck 16 is attained.
  • the use of constant, close-fitting tolerances at the driving flats 2026 has been found unexpectedly to not interfer with initial, quick insertion of the roll neck 16 into the connector 12, assuming proper alignment of the roll.
  • a second close fit is surprisingly provided by the coupling arrangement adjacent the other end of the engagement between the roll neck 16 and the connector 12.
  • a supporting disc 44 or other suitably shaped member is secured in the connector 12 (as by welding or shrink-fitting) adjacent the inward extremity of its coupling bore 14.
  • a sturdily constructed projection 46 formed for example integrally with the support disc 44, protrudes toward the roll neck 16, when the latter is engaged with the connector 12.
  • the projection 46 includes an annular extension 50 which is closely seated in annular recess 52 milled in the adjacent end surface of the roll neck 16 when the roll neck is fully engaged within the connector 12, as best shown in FIG. 1.
  • an operating clearance 54 remains at the bottom of the annular recess 52.
  • the projection 46 and its engagement with the adjacent end of the roll neck end portion 18 provides a second close-tolerance fit, which is most appropriately located adjacent the other extremity of the engagement between the connector 12 and roll neck end portion 18. This close engagement is accomplished near the end portion of the entering operation, as the tapered pilot clearances at the conical or tapered surfaces 32-38 guide the roll neck end portion 18 and the connector 12 into a close-tolerance coupling fit.
  • the roll neck end portion 18 can be quickly removed from the connector 12 simply by withdrawing these components longitudinally.
  • a replacement roll can be quickly engaged with the coupling 10 simply by initial engagement of the champfered portions 28, 30 followed by an increasingly close tolerance entry movement as the neck end portion 18 of the replacement roll is inserted into the connector 12.
  • a thrust plate 64 of the spindle 58 engages through thrust button 66 the adjacent surface of the connector support disc 44 of the coupling 10 for purposes of thrust absorption.
  • a coupling for a mill roll and the like comprising a connector having a coupling bore therein, said bore having a first surface shaped for close fitting engagement with a neck portion of said roll adjacent one longitudinal extremity of a coupling engagement therebetween, a second surface shaped for close fitting engagement with said roll neck adjacent the opposite extremity of said coupling engagement, and a third surface disposed generally between said first and said second surfaces and shaped for an increasingly close fit with said roll neck as said roll neck is increasingly inserted into said connector.
  • the combination according to claim 1 including a roll neck portion shaped for insertion into said coupling bore, said portion including constant tolerance surfaces for close fitting engagement with said first and said second connector surfaces and avarying tolerance portion shaped for increasingly close engagement with said third connector surface.
  • each of said first, said second and said third surfaces is disposed to prevent angular displacement of said roll neck relative to said coupling bore when said roll neck is fully inserted into said connector.
  • each of said first and said second surfaces are shaped for initially and continuously close-fitting engagement with complementary surfaces respectively of said roll neck as said roll neck is progressively inserted into said coupling bore.
  • each of said first and said second surfaces is shaped to prevent angular displacement of said roll neck relative to said coupling as said roll neckis progressively inserted into said coupling bore.
