  • Patent number: 4159152
    Abstract: An oil film bearing for a roll neck in a rolling mill, wherein a sleeve with a tapered bore in mounted on a tapered section of the roll neck for rotation therewith, the sleeve being journalled in a non-rotatable bushing contained in a bearing chock. During rolling, a film of high pressure oil is maintained hydrodynamically between the sleeve and bushing at the bearing load zone. In order to provide lubrication at the roll neck/sleeve interface, a portion of the hydrodynamic oil is bled from the sleeve/bushing interface via holes extending radially through the sleeve into a plurality of longitudinal primary grooves in the sleeve bore. This conventional arrangement is improved by the addition of a plurality of secondary grooves in the sleeve bore. Oil is forced from the primary grooves into the second grooves via connecting grooves in the sleeve bore. The connecting grooves create a pressure differential which opposes reverse flow of oil from the secondary grooves into the primary grooves.

  • Patent number: 4098393
    Abstract: An apparatus for laterally separating a group of elongated magnetic elements, for example steel bars which are moving longitudinally along a conveyor. A rotatable fanning roll extends transversally across the path of the bars. The fanning roll has a magnet associated therewith. The magnet attracts the bars towards the fanning roll while simultaneously creating repulsion forces tending to laterally separate the bars. A deflecting roll located in advance of the fanning roll is employed to deflect the bars out of their normal path of travel in relation to the surface of the fanning roll to thereby produce a momentary separation between the front ends of the bars and the fanning roll. During this momentary separation, the magnetically induced repulsion forces are not impeded by frictional resistance between the bars and the surface of the fanning roll, and this in turn improves the resulting lateral bar separation.

  • Patent number: 4095901
    Abstract: An apparatus for observing the relative alignment of two pairs of guide rollers on a rolling mill roller guide. The roller guide is positioned with its guide roller pairs spaced along an axis extending between two light sources. A dichroic mirror is arranged between each pair of guide rollers and its adjacent light source. One dichroic mirror reflects blue light while transmitting red light, and the other dichroic mirror reflects red light while transmitting blue light. The light reflected from both dichroic mirrors is recombined by a third dichroic mirror and is then projected onto a screen as red and blue images which may be compared visually with a reference outline on the screen, the said outline being representative of proper guide roller alignment. When the roller pairs are properly aligned, the red and blue images coincide on the screen to produce a white image aligned with the reference outline.
