Definitions

  • the invention relates to a seal assembly for sealing the roll side of a roll bearing wherein at least one elastic seal element on the roll stub rides on an annular seal surface, the seal element and seal surface being mounted on respective supports one of which is stationary and the other of which is movable with the roll stub.
  • seal assemblies have long been used in oil-film bearings.
  • seal elements are used which on the one hand prevent oil from getting from the oil-film bearing to the roll body and on the other hand prevent particle-carrying coolant and lubricant from getting from the roll body into the oil-film bearing.
  • the roll stub can get radially offset in its mount.
  • the seal space between the roll-stub sleeve and the bearing sleeve is less in a lower region, whereas the gap is greater in the opposite upper region. If the roll is working and pressure is being exerted from the mount through the bearing to the roll, the bearing gap between the roll-stub sleeve and the bearing sleeve is greater in the lower region whereas in the opposite upper region it decreases. This radial offset created by different loads must be compensated out by the seal elements.
  • the invention attains this object in that the seal element and/or the seal surface are supported by at least one elastic support element on the holder, the elastic support element being less stiff than the seal lips of the seal element.
  • the seal lip of the seal element is not changed in shape in a smaller seal gap, but as a result of its greater stiffness the forces are applied to the elastic support element carrying the seal element, which is compressed in this region of the seal gap.
  • the elastic support element can expand in the larger seal gap so that here also the seal lip sits without substantial movement in an optimal manner on the seal surface.
  • the seal element and/or the seal surface is retained in its holder between at least one clamp body and if necessary an abutment, the clamping permitting a radial movement of the seal elements and/or of the seal surface, angular movement of the seal element being prevented.
  • a stationary seal element is not entrained by friction with the seal surface while being able to follow radial movement.
  • the elastic support element can be an O-ring or closed-end tube that e.g. is filled with an elastomer so as to ensure an optimal equalization of radial offset.
  • the clamp body and if necessary the extension and/or the surface of the seal element and/or the seal surface that engage the abutment and if necessary the abutment are coated with Teflon. This makes possible radial movement of the seal element or of the seal surface in its holder.
  • FIG. 1 is a view of a roll with an oil-film bearing
  • FIG. 2 is a detail of the seal.
  • FIG. 1 shows a roll 1 having a roll stub 2 .
  • the roll stub 2 is supported as shown in FIG. 2 by a roll-stub sleeve 3 in a bearing sleeve 4 which in turn is carried by a mount 5 .
  • the roll-stub sleeve 3 carries a roll-stub sleeve extension 6 having a seal surface 7 .
  • the mount carries a holder 8 that in turn carries seal elements 9 and 10 .
  • the seal elements 9 and 10 themselves are pressed by a clamping body 11 against an abutment 12 such that the seal elements 9 and 10 can move radially but not angularly in the holder 8 .
  • Between the holder 8 and the seal elements 9 and 10 is an elastic support element 13 .
  • the elastic support element 13 is formed as a closed tube filled with an elastomer.
  • the seal elements 9 and 10 compensate out this radial offset. Since the elastic element 13 is not as stiff as the lips 14 and 15 of the seal element 9 and 10 , the elastic support element 13 can take up the radial offset without substantial bending of the seal lips 14 and 15 . This ensures that the seal lips 14 and 15 are always seated on the seal surface 7 for optimal sealing. In addition with this positioning of the lips 14 and 15 there is minimal wear.
  • the illustrated embodiment shows only that the seal elements 9 and 10 are supported by the elastic support element 13 . It is also within the scope of the invention that such an elastic support element be provided between the seal surface 7 and the roll-stub extension 6 , or that both the seal element and the seal surface are supported by respective elastic support elements.
