Definitions

  • the present invention aims to permit rotation, without end play, of the rolls in a wire rolling unit in their bearings, as well as to permit vertical displacements, also without end play, of the bearings in the roll. housings of the unit, by the provision of a systemvv-hich ⁇ takes up yieldably all the play which would iniiuence the lateral shifting of a roll in the roll unit.
  • the two bearings of a roll may be mounted in a single block.
  • Such an arrangement is advantageous in that it brings about a thorough alignment of thetwo needle-shaped roller bearings and tends to decrease lateral thrusts caused by said rollers, but-it is notan indispensable feature of the invention.
  • Fig. 1 is a sectionallview showing the mounting of a roll in a wire rolling unit, according to the present invention
  • Y Fig. 2 is a iragmentaryview of another mounting of such a roll.
  • the block I is adapted to receive the needleshaped roller bearings 2 and 3 in cylindric members 4, 5, respectively, machined concentrically with respect to the axis of the roll 6 which has journals 'I and 8 adapted tov rotate inthe bearings 2 and 3.
  • the faces 9 and II of the block I which are I parallel to each other., are adapted to slide without playbetween the columns I2, I3, Hand I5 of the roll housing.
  • the springs 22 are selected to withstand lateral thrusts caused by the needle-shaped rollers and pass shapes. They permit the block ⁇ I to slide without any lateral play at right angles to the plane of the drawing. This sliding is necessary for the purpose of regulating the distance between the rolls.
  • the roll 6 itself is maintained without end play in the bearings as follows:
  • the journal l which is adapted to be motordrven at 24, may-rotate freely in the needleshaped roller bearings 2.
  • the journal 8 may rotate freely in the needleshaped roller bearing 3.
  • the free end of journal 8 carries, disposed between its shoulder 25 and a cup-like member 26 which is pressed by a nut 2l screwed on the threaded end- 2B of ⁇ journal 8, the central race 23 of a double thrust ball bearing of which one outer race 3
  • the other outer. race 33 of this ball bearing is strongly pressed, by a suitably shaped cap 34, acted upon by a spring composed for example of Belleville washers 35, surrounding a nipple 36 coaxial with the cap 34 and roll 6.
  • This spring is acted upon by an adjustable plug 3l which maybe screwed down or up within a cover member 38 adapted to maintain the cylindrical member 5 in place in the block- I .K
  • a cover member 38a holds members 2- and 4 in position.
  • the spring 35 is selected to withstand lateral thrusts due to inclinations of the needle rollers and pass sections.
  • FIG 2 whichI represents only one of the trunnions of the roll, there is shown a mounting in which account is taken of the fact that the rolling mill has its rolls inclined at an angle of 45 degrees. Owing to this inclination, the needle bearings are subjected to an end friction which subjects their lower end to a greater braking action, which causes them to be disposed in an inclined position about the axis 40. As a result of this inclination of the needles in the roller bearing, there is an axial reaction on the axis 40, similar to that obtained by screwing in a screw, which tends to displace the axis of the rolling mill upwardly. In operation this reaction tends to urge the roll with force against the stop 4I.
  • a spring 42 which is compressed between the race of the needle roller bearing and the race 43 of the thrust bearing by a cap 44 secured withinthe piece 5 ofthe block I and bearing against cover member 45, merely serves to maintain, against the force of gravity, the roll applied against its abutment whenever the machineis stopped, i. e., when the thrust due to the needle rollers ceases.
  • the structure of the embodiment of Fig. 2 is substantially like that of Fig. 1.
  • a bearing construction coinprising, a block having two parallel lateral faces, said block being slidable along said faces between said columns in a direction perpendicular to the axes of said rolls, fixed guiding slides on said columns engaging one end face of said block, seco-nd guiding slides on said columns engaging the opposite end face of said block, adjustable spring means acting on said second slides pressing the slides against said end face, bearing housings coaxially mounted in said block, said needle roller bearings being carried in said sliding members by said bearing housings and journaling the opposed necks of the working roll, a thrust bearing at one 'of said roller necks mounted in one of said bearing housings, said housing having an inner abutment engaging said thrust bearing, one race of said thrust bearing being fixed to said roller neck, and spring means acting on said thrust bearing to press the same against said abutment, said two spring means acting on said slides and said thrust bearing being of sufficient strength to
  • a bearing construction comprising, a block slidable with two lateral faces parallel tothe axes of said rolls between correspending faces of said columns in a direction perpendicular to said axes, fixed guiding slides on said columns perpendicular to said axes engaging one end face of said block, second guiding slides on said columns engaging the opposite end face of said block, both of said end faces being perpendicular to the axes of said rolls, adjustable spring means acting on said second slides pressing the slides against said end face, bearing housings coaxially mounted in said block, said needle roller bearings lbeing carried in said sliding members by said bearing housings and journalling the opposed necks of the.
  • a bearing construction for a rolling mill having inclined working rolls journalled in needle roller bearings and a frame with parallel columns perpendicular to said working rolls, said bearing construction comprising a block slidable with two-lateral faces between said columns in a di- ,Y rection perpendicular to said inclined rolls,
  • bearing housings coaxially mounted in said block, said needle roller bearings being carried with their outer races in said bearing housings and journalling the opposed necks of the work roll, a ball thrust bearing at the upper end of said inclined working roll mounted in one of said bearing housings, said housing having an inwardly facing abutment means, said thrust bearing having two concentrical races, the inner race of which being fixed to said upper r-oll neck above said needle roller bearing and the outer l race engaging said abutment, and a helical spring mounted about said roll neck between the outer races of said needle roller bearing and said ball 5 thrust bearing, said spring thereby pres-sing said Number thrust bearing against said abutment and being 1,891,579 of sufficient strength to counteract the weight 2,200,837 of the roll. 2,205,049 JEAN ROZIERES. 5 2,299,631
