Definitions
- the invention relates to a device for returning oil from the area of the side surface of the bale and the circumferential surface of the journal of rolling mill rollers mounted in the bearing of a bearing chock, in which a sealing race arranged between the bearing elements and the side surface of the bale is mounted on the journal ,
- the object of the invention is to improve the known oil return systems in such a way that the risk of leakage, even from small quantities of oil, is eliminated with great reliability and with little maintenance.
- a device for returning oil of the type mentioned at the outset which is achieved by an outer cone surface, the inclination of which is inclined from the ball side, by a cone ring body which is seated on the outer surface of the seal race and is sealed against it runs in the direction of the roller axis and a further, fixedly arranged in the bearing housing second cone ring body with an inner cone surface, which lies opposite the cone surface of the first cone ring body at a distance, forms with this a hydraulic pumping gap that promotes oil away from the bale side of the roller ,
- the end of the pump gap facing the roll bale can open into an annular inlet chamber, the side surfaces of the first cone ring body which run axially and inclined thereto, the radial side surface of a flange-ring-shaped extension of the second cone ring body which is at a distance from it and an outer surface portion of the sighting race is formed.
- the outlet end of the pump gap facing away from the roll bale can open into an annular oil collecting chamber, which comes from a radially extending side surface of the second cone ring body, a side surface opposite this at a distance from a flange-shaped ring shoulder arranged firmly in the bearing housing and a side wall section of the first cone ring body is formed, with the oil collection chamber, radial guide channels arranged in the bearing housing and a discharge channel downstream of these being assigned.
- the first conical ring body can have an axially radial contact surface for contact with an annular support surface, which also extends axially radial, in the stationary part of the bearing and can be made of a wear-resistant material at an axial distance from the outlet end of the pump gap.
- This device is not only characterized by greater reliability with a construction work comprising only a few parts; it can also be installed in existing sealing systems of roller bearings without any particular additional effort, since it does not build larger than the space required by the double sealing systems that are no longer required.
- the device is also suitable for use in rolling mill bearings for other purposes.
- FIG. 2 shows a detail from the illustration of FIG. 2 on an enlarged scale
- FIG. 3 shows the detail of FIG. 2 on a further enlarged scale.
- the roller bearing consists of a pair of radial roller bearings seated on the journal WZ of the roller W and one on the end WZE of the journal facing away from the roller barrel WB of the roller.
- the radial roller bearings are pushed into the bearing insert LES and the Radiax bearing RDL is seated in an end ring body ARK, which is attached to the bearing insert LES on the side facing away from the roll barrel WB.
- An intermediate ring body ZRK is located on the other side of the bearing chock LES facing the rolled bale WB set up, which is equipped with sealing elements and sealing devices which will be explained in more detail below.
- Oil is supplied to the bearings in a manner not shown via feed channels ZFK and adjoining guide channels FK and discharged again via discharge channels AK.
- a sealing race DLR is mounted on the journal WZ, the outer circumferential surface of which is connected to an elastic labyrinth ring which is firmly connected to the intermediate ring body ZRK LR is sealed. Furthermore, a first conical ring body KRK1 with a cylindrical inner surface is drawn onto the cylindrical outer circumference of this seal race DLR, the outer ring surface ARF of which runs in the direction away from the roll bale WB and inclined towards the roll axis x-x (FIG. 1).
- the first conical ring body KRK1 has, with an axial distance from the outlet end of the pump gap PS, an annular, axially radial contact surface ANF for the contact with a likewise axially radial axis Contact surface OPEN on a bearing-fixed ring piece RS of the bearing and is made of wear-resistant material.
- the gap PS formed between the two acts as a hydraulic centrifugal pump, which flows out of the bearing in the area of the end face ST of the roll barrel and the outer surface of the seal race Oil parts that have entered the suction chamber EK are sucked off and led back into the oil circulation of the bearing via the oil collection chamber OSK, the guide channels FK and the discharge channel AF and thus prevent the oil from reaching the end face ST of the roll barrel WB and via this onto the peripheral surface of the roll barrel.
- the device is also suitable for suctioning off smaller quantities of liquids, such as cooling water or lubricating emulsion residues, which come from the outside of the roll bale into the bearing via defective seals, and discharge them via the oil circuit of the bearing.
- liquids such as cooling water or lubricating emulsion residues
