Definitions

  • the invention relates to a sealing device for roller bearings in roll stands, in which the roll neck has a conical section between the end face of the roll and the area of the roll neck equipped with a journal bushing, which is mounted in a bearing bush in the bearing housing, with a one-piece, ring-shaped, flexible and by means of wire rope and if necessary a wire band stabilized sealing body, which is pushed onto the conical section and rests with ring sealing lugs on the latter, the ring sealing lug on the journal bushing side being stabilized by means of a helical spring and the sealing body with the outer ring end having at least one of two radial, elastic ring ribs arranged at an axial distance elastic frictional contact can be applied to at least one housing-fixed or cover-fixed annular sealing surface arranged on the side of an annular collar.
  • Such a sealing device has become known from DE-OS 36 01 238.
  • the area between the two ring ribs is surrounded by a steel band.
  • the steel band counteracts the centrifugal forces and keeps the sealing body in shape. So that the sealing body remains stable in itself the middle area of which is provided with a wire rope ring and a coil spring surrounding it.
  • the ring seal shoulder on the journal sleeve side is provided with a helical spring in order to ensure that the ring seal shoulder sits securely against the roll neck against the centrifugal force.
  • the invention has for its object to improve a generic sealing device in such a way that a consistently good sealing effect and low wear of the sealing elements is ensured even at high rotational speeds.
  • the sealing body region holding the ring rib on the journal bushing in one piece is reinforced by a wire rope ring.
  • the wire ring has the effect that this area of the sealing body and the ring rib connected in one piece with it cannot move outwards following the centrifugal force onto the sealing surface. At the same time, this area is prevented from being able to bend around the integrally formed connecting web to the sealing body, so that the sealing rib is always aligned parallel to the fixed annular collar of the bearing housing.
  • the wire rope ring can be held securely in a certain position.
  • wire ring is provided in the end region of the sealing body on the journal sleeve side, it is ensured that all areas of the sealing body are adequately reinforced, so that no deformation and bending can occur on the elastic sealing body.
  • FIG. 1 of the drawing shows a sealing body 1, as it can be used at arbitrarily high speeds.
  • the sealing body 1 is pushed onto the conical shoulder 2 of a roll neck 3.
  • the roll neck 3 of the roll 4 is seated in a pin bush 5 which is in contact with the roll neck 3 turns.
  • the bearing bush 5 is mounted in a bearing bush 6 of the fixed bearing housing 7.
  • the gap between the journal bush 5 and the bearing bush 6 is constantly supplied with oil.
  • a gutter 8 of the bearing housing 7 forms an oil sump. The oil flows out for reprocessing via a drain hole 9.
  • the sealing body 1 is intended to prevent the oil emerging from the bearing gap from reaching the roller. In cases in which coolant is applied to the rolling stock or the roll, the sealing body is also intended to prevent the oil from mixing with the cooling liquid.
  • the sealing body has two ring sealing lugs 10, 11 in order to seal tightly with the lug 2 of the roll neck 3 both on the oil side and on the coolant side.
  • a helical spring 12 is assigned to the ring seal attachment 10 in order to ensure a secure pressure on the attachment 2.
  • a combination of a coil spring 13 and a wire rope ring 14 serves to reinforce the sealing body 1.
  • the cylindrical outer peripheral surface of the sealing body 1 is enclosed by a steel band 15 as a reinforcing element.
  • An annular sealing element 16 can be used in wet operation.
  • Ring ribs 17, 18 are integrally formed on the sealing body 1.
  • the tips of the ring ribs 17, 18 merge into ring lips 19, 20.
  • the annular lips 19, 20 run on fixed sealing surfaces 21 which are firmly connected to the cover 27 of the bearing housing 7.
  • An annular collar 22, which is between the annular ribs 17, 18 is arranged and points to the sealing body 1.
  • the ring ribs 17, 18 with their ring lips 19, 20 and the ring collar 22 form a labyrinth in which oil or coolant particles that have passed the ring lips can catch.
  • An oil-deflecting lug 23 is provided on the sealing body 1 and is intended to guide the oil emerging from the bearing gap into the oil sump.
  • a wire rope ring 25 surrounded by a helical spring 24 is vulcanized into the sealing body 1.
  • This wire rope ring 25 with its helical spring 24 also serves to reinforce the sealing body 1.
  • the wire rope ring 25 is arranged in such a way that the area 26 of the sealing body 1, which has the sealing rib 18 and the oil-repelling nose 23, has a relatively large mass remains stable at high speeds.
  • FIG. 2 showed the behavior of a known sealing body 1 at high speeds of rotation. With the large mass of the region 26, the flying force causes it to be moved by being strongly bent outwards.
  • the annular rib 18 is no longer aligned parallel to the annular collar 22 and can grind on the annular collar 22 even with small axial displacements of the roller and thus of the sealing body 1, as a result of which the annular rib 18 is destroyed.
  • the pressure on the annular lip 20 is so strong that its tip bends back onto the sealing body 1.
  • the sealing lip 20 is subjected to very heavy wear. In this position, perfect sealing is essential Ring lip 20 no longer possible, so that a lot of oil can get into the labyrinth. Here it either mixes with the coolant and can then no longer be used, or it even reaches the rolling stock, where it reduces the quality of the rolling stock.
  • the sealing body can be further damaged in that the oil-repelling nose 23 rubs on the sealing surface 21 and is destroyed in the process.
