Description
- This application is a divisional of U.S. patent application Ser. No. 10/467,701 for a FLANGE SLEEVE, METHOD FOR THE PRODUCTION THEREOF AND BENDING TOOL FOR PRODUCING FLANGES ON A SLEEVE, filed on Dec. 8, 2003.
- 1. Field of the Invention
- The invention relates to a flanged bush, in particular a flanged bush for plain bearings with at least one flange formed thereon, according to the precharacterizing clause of
claim 1, a method for the production thereof according to the precharacterizing clause of claim 9 and a bending die according to the precharacterizing clause ofclaim 13. - 2. Description of Related Prior Art
- Flanged bushes, which comprise either one or two flanges, are known in a very wide range of sizes, with diameters ranging from centimeters to decimeters. The materials used depend on the intended application, wherein the bush material may be of single- or multilayer construction. Single-layer bushes are known as solid bushes. Bushes of multilayer construction generally comprise a backing material and an overlay. The overlay may consist of a metal alloy or plastics. The invention relates to all flanged bushes, irrespective of their dimensions, intended purpose and the materials used, with the one reservation that the flanged bushes have to comprise at least one metallic layer.
- To produce flanged bushes, an edge of prefabricated bearing sleeves or bushes is bent into a flange in a secondary operation. A conventional method is bush wrapping, wherein a flat strip portion, the so-called blank, is wrapped round to form a bush or sleeve.
- In the case of wrapped bearing bushes, it is generally necessary for the butt joint to be closed when the bush is fitted, while the butt joint is generally not fully closed when the bearing bush is not fitted, since the material springs open to a greater or lesser degree depending on the method used to produce the bush 9c.f. DIN 1494,
part 1, Jun. 1983, p. 1). - Production methods for wrapped bushes are known and are described for example by Dipl.-Ing. Hugo Kotthaus in ‘Betriebstechnisches Taschenbush”, vol. 2, 7th edition, Karl Hanser Verlag Munich, 1967, pp. 212ff.
- To close open butt joints, it is proposed in DE-OS 23 17 564 to heat the bushes and simultaneously to prevent an increase in diameter as a result of thermal expansion.
- Both with this known method and with a shaping method described in DE-PS 517530, is it possible to close the butt gap in bushes.
- However, if such prefabricated bushes are shaped into flanged bushes, by bending the edge of the bush, the butt joint opens up again, wherein the gap width may assume considerable dimensions depending on the diameter and flange width.
- Flanged bushes with gaps can only be fitted using special tools, with which the flanged bush is compressed through the application of considerable force, wherein the flanged bush may possibly also warp, causing damage to the flanged bush.
- Relatively small flanged bushes, which are transported in large numbers in cartons as loose cargo, may become hooked together, often resulting in a chain of several flanged bushes. The buyer has to separate the flanged bushes laboriously and generally by hand before fitting them. There has therefore long been a desire for flanged bushes with closed butt joints.
- In flanged bushes, a closed butt joint could only be achieved by welding a ring forming the flange to a bush. The disadvantage of this method is that welding is more expensive than bending of the bush edge.
- It is therefore the object of the invention to provide a bush with closed or extensively closed butt joint which does not cost any more to produce than the conventional flanged bushes obtained by bending.
- A further object of the invention is to provide a suitable method and an appropriate device or bending die.
- As far as the method is concerned, the object is achieved in that, at least two points distributed around the flange in the circumferential direction, material-displacing recesses are formed at least in the metal layer of the flanged bush.
- It has surprisingly been demonstrated that the material displacement caused by the formation of the recess stretches the flange in the circumferential direction in such a way that the butt gap is closed.
- The formation of material-displacing recesses is a cost-effective method, especially if the recesses are produced, as preferred, by stamping.
- The recesses may be formed in the inner and/or outer surface of the flange. Where the recesses are formed depends on the structure of the flanged bush, the material and the intended application. If the flanged bushes are intended for diesel engines, for example, the bush consists as a rule of a metallic backing material, on which at least one overlay has been applied. In order not to damage the overlay by the formation of material-displacing recesses, the recesses are preferably formed in the inner surface of the flange.
- If, in the case of coated bushes, the recesses are to be formed additionally or solely in the outer surface of the flange, the recesses have to extend into the metallic backing layer, since otherwise not enough of the material causing the springing-open effect is displaced.
- The recesses are preferably produced when bending the bush edge. Incorporation into the bending process has the advantage that no additional method step is necessary, such that the production costs do not increase relative to conventional flanged bushes. If the material-displacing recesses are formed in the flange during bending, the butt joint cannot open in the first place.
- Closure of the butt joint may be controlled or the width of the butt joint may be specifically adjusted, depending on the intended purpose of the bush, by means of the size, number, shape and depth of the recesses.
- The flanged bush according to the invention, which comprises no butt gap or comprises a specifically adjusted butt gap, is characterized in that the flange comprises material-displacing recesses at least in the metallic layer at least two points distributed over the flange in the circumferential direction.
- The recesses preferably take the form of impressions, and are preferably located in the inner and/or outer surface of the flange. In a further preferred embodiment, the recesses extend as far as into the outer edge of the flange. It has been demonstrated that the material-displacing recesses are most effective, the further they are formed towards the outside, when viewed in the radial direction. The number of recesses may be markedly reduced relative to the number of recesses which do not extend as far as into the outer edge of the flange. The recesses preferably widen radially form the inside to the outside. In this way, greater material displacement is caused where the circumference becomes larger. The recesses are preferably semicircular or wedge-shaped.
- As an alternative or in addition to the widening of the recesses, it is advantageous for the recesses to increase in depth form the inside radially towards the outside, because the associated increase in material displacement takes account of the radially outward increase in circumference. The recesses preferably extend radially over the entire width of the flange.
- The bending die according to the invention is characterized in that elevations are provided at least two points distributed over the end face in the circumferential direction of the end face. The elevations are preferably arranged equidistantly in the circumferential direction. The elevations may exhibit a circular, oval or wedge-shaped structure. It is also possible for the elevations to take the form of radially extending webs. The elevations may be formed on the end face or take the form of exchangeable components which are inserted into the end face. Punches projecting relative to the end face are preferably inserted into the end face. The punches which may be inserted are preferably pins, which are inserted into corresponding drill holes in the end face of the bending die. It is thereby possible to arrange the bending die in variable ways, and thus, to adapt it to various widths of flanges, the diameter of the flanged bush remaining the same.
- The bending device according to the invention comprises a bending die and a pressure plate acting on the bush edge to be bent, wherein the bending die and/or the pressure plate comprise elevations on the surface facing the bush edge.
