Definitions
- the invention relates to a pin seal for roller bearings, wherein the pin seal comprises:
- An annular sealing body which is rotatably connected with its coaxial with the roll axis bearing surface is connected to a roll neck and with at least two of the roll axis directed away, spaced, webs is formed which are directly or indirectly in contact with a ring shoulder of the roller bearing;
- Tap seals of this type are preferably used to seal roll neck bearings in roller mills; they are designed to prevent the escape of oil from the bearings and to prevent the ingress of foreign bodies, such as coolant or roller sinter into the bearing.
- the high rotational speeds of the rolls of a rolling train have a corresponding load on the bearings and the sealing devices by occurring centrifugal force effects result.
- the sealing bodies are reinforced with a reinforcing element.
- the reinforcing element is incorporated in the sealing body or arranged outside between the spaced webs.
- a seal for the tapered region of a roll neck of a roll stand.
- the seal comprises a flexible circular seal body having a central axis and at least one radially outwardly extending flange connected by a connecting bridge to an angularly extending lip having convergent first and second sides.
- the connecting bridge has a reduced thickness compared to the thickness of the flange and the lip.
- the converging first and second sides of the lip lead to an enlarged rim and the lip has first and second outer surfaces converging in an outer edge parallel to central axis A in a reference plane.
- a sealing device for roller bearings in which the roll neck between the roller end face and the bearing journal has a conical section on which an annular, flexible sealing body can be pushed, which on the side facing the roller end face a, extending in the axial direction annular sealing rib, wherein when pushing the sealing body on the conical Waizzenzapfenabites by thereby becoming effective radial pressure, applying a bending moment, the annular sealing lip in a, inclined to the axial direction, applied to the outer surface of the conical roll neck portion position becomes.
- the sealing body has at its, the outer surface of the conical portion of the roll neck facing inner ren ring surface axially offset relative to the annular sealing lip annular shoulder approaches that apply under the axial pressure on the sealing body a bending moment, which is directed opposite to the bending moment applied to the annular sealing lip.
- Pin seals with two webs, which are formed with sealing lips, and a reinforcing element supporting the sealing body are known from DE 37 21 265 A1, EP 1 430 962 A1, EP 1 442 804 B1, EP 1 447 149 A2, WO 2005/037 455 A1 and US 4,099,731.
- the oil slipping lip on the oil-side sealing lip can bend so far that it comes into contact with the running diameter of the oil-side sealing lip.
- journal seal for roller bearings
- the journal seal comprises: an annular seal body which is connected with its roll surface coaxial with the roller axis rotationally fixed with a roll neck and with at least two away from the roll axis, spaced, webs is formed, which are directly or indirectly in contact with an annular shoulder of the roller bearing, - a reinforcing element for reinforcing the sealing body, and wherein the reinforcing element has a width which is greater than the outer spacing of the two webs.
- reinforcing element By embedded in the sealing body reinforcing element, whose axial extent is greater than the outer distance of the webs, ensures that when pulling / pushing the pin seal and its rotation during rolling on the roll neck no tilting moment acts on the webs. Thus, there is a most extensive decoupling between the area of the pin seal having the webs (directed away from the roll axis) and the area of the pin seal between the reinforcing element and the bearing surface (pointing to the roll axis).
- the bearing surfaces which are in contact with the roll neck are in each case formed symmetrically to the radial center planes of the webs and the bearing surfaces which are formed independently of one another are configured so that the radial compression of the annular sealing body takes place such that the prestressing the webs and their continuation, the sealing lips, is equal to the ring approach.
- no unwanted tilting moments are transmitted to the webs and the sealing lips assigned to the annular shoulder.
- the voltage applied to the roll neck bearing surfaces of the seal body are slightly displaced. However, the displaced material of the sealing body is at least partially penetrated along the reinforcing element into a cavity, so that no forces or moments act on the webs.
- the gap thus serves as a powerless collecting space for the displaced material.
- the material to be displaced of the sealing body is thereby, seen in the radial direction, on the side facing the roll neck side, ie the opposite side of the webs of the reinforcing element.
- the bearing surfaces in contact with the roll neck are each formed symmetrically to the radial center planes of the webs. Such a design of the surfaces ensures that the forces acting radially outward on the reinforcing element, over the width of which are the same size.
- the cavity is located between the two surfaces and is designed so that the material to be displaced opposes no resistance.
- the cavity in cross-section, for example, the shape of a right triangle, one of whose cathodes is aligned parallel to the roll axis.
- the reinforcing element made of steel, steel fabric, plastic fabric, Kevlar, aramid or carbon fiber.
- fabric or fibers it is possible to simplify the production of a reinforcing element having different rigidity, for example by forming one region of the reinforcing element from five layers and another region from eight layers.
- the cross section of the reinforcing element is S-shaped or U-shaped.
- the legs of the U-shaped reinforcement element point towards or away from the roll axis.
- FIG. 2 shows a partially sectioned side view of a sealing device, comprising a sealing body and a reinforcing element supporting the sealing body;
- FIGS. 1a to 1f show known plug seals 3 which have a sealing body 50 with a reinforcing element 51.
- the dot-dash line shows the position of a roll axis 52.
- the exact arrangement of pin seal, roller, etc. is shown in FIG.
- the sealing body 50 has a bearing surface 53 directed in the roll axis 52 and at least two webs 54, 55 pointing radially away from the roll axis 52.
- the sealing body 50 is formed with an embedded reinforcing element 51 in the form of a wire rope / a coil spring and a between the webs 54, 55 arranged reinforcing element 51 in the form of a metal strip.
- the bearing surface 53 extends from a left end 56 to a rake end 57 and has a contour which at different locations in the installed state against the roll neck (not shown).
- the left end 56 and the right end 57 also has different contours, a reinforcement of the right end 57 in the form of another reinforcing element is shown.
- a centrifugal lip 58 which deflects the oil emerging from the gap between the journal bush and the bearing bush 6 (see FIG. 2).
- sealing lips are formed, which have different shapes in Figure 1 b.
- the sealing body 50 shown here has no embedded reinforcing element but only one between the webs 54, 55 arranged reinforcing element 51.
- Figure 1c shows a pin seal 3 as in Figure 1b, the webs 54, 55 are equipped with mirror-image formed sealing lips.
- Figure 1d shows the configuration of a pin seal 3 according to Figure 1b with the reinforcing elements 51 of Figure 1a.
- Figure 1e shows the embodiment of Figure 1a, wherein the web 54 is changed.
- Figure If shows the embodiment of a pin seal 3, in which the webs 54, 55 have no sealing lips.
- a roller 1 is shown with a roll neck 2 in a partially sectioned side view.
- a pin seal 3 by means of a pin bushing 4, which is rotatably mounted on the roll neck 2, pushed.
- the pin bushing 4 holds the annular pin seal 3 in Position.
- the roll neck 2 with the rotatably mounted pin bushing 4 are arranged in a bearing housing 5 with bearing bush 6. Between the rotating pin bush 4 and the fixed bearing bush 6 there is a gap 8, through which a lubricant is conveyed, which is removed by a discharge chamber 9 from this region of the bearing. For deflecting the oil in a certain direction, a centrifugal lip 58 is formed on the pin seal 3.
- FIG. 3 an embodiment of the sealing device according to the invention is shown in cross section.
- the reinforcing element 51 is greater in its width 60 than the outer spacing 59 of the webs 54 and 55.
- the sealing lip 56 of the sealing body 50 is designed so elastically that it can be brought from the initial state (shown in phantom) in their installed state without major force.
- the sealing lip 57 of the sealing body 50 can be designed, for example, as known from FIGS. 1a to 1f.
- the bearing surfaces 53-1 and 53-2 of the annular seal body 50 are separated by a circumferential cavity 64 and each can be formed independently.
- the contact forces for the overlying webs 54 and 55 are adjusted with the attached sealing lips 65 so that the two sealing lips 65 each have the same biasing force against the bearing located on the bearing ring projection 7 (see Figure 2).
- the bearing surfaces 53-1 and 53-2 are each arranged symmetrically to the respective center axis 61 or 62 of the webs 54 or 55.
- the reinforcing element 51 and / or the material of the sealing body (50) located respectively between the reinforcing element 51 and the bearing surface 53-1, 53-2 can have an increasingly greater rigidity. This can be achieved, for example, by using materials with different moduli of elasticity. 5 list of reference numerals
