Definitions

  • the invention relates to a method for coating the tread of a bearing component, in particular for a bearing of a turbomachine shaft.
  • the invention also relates to a bearing component.
  • Suitable materials offer a smooth, polished surface during the running-in period, unsuitable ones roughen up and tend to “eat.” Even with the right choice of material, for example due to lubrication failure, temperatures that reach the melting point of steel can occur locally at the points of contact used by turbine rotors For this reason, a bearing material with a low softening or melting point, for example white metal. This melts at temperatures that do not pose any danger to the cone. On page 96 of the same book it says: "The part of the bearing that contains the tread is called if it is undivided (or only slotted), liner. If it is divided, then the halves are called "bearing shells".
  • Bearing damage is described from page 65 onwards, which various causes of bearing damage can have. Soiling, wear, corrosion, washout / gravitation, fatigue, overheating, binding errors and installation errors are mentioned.
  • the object of the invention is to provide a method for coating the tread of a bearing component with a bearing material, which leads to a durable and reliable tread coating.
  • Another object of the invention is to provide a bearing component that has a long service life due to a durable coating of its running surface with a bearing material.
  • the object directed to a method is achieved by a method for coating the tread of a bearing component with a bearing material, in which the bearing material is applied to the tread of the bearing component and melted by means of a laser beam.
  • the running surface of the bearing component is the surface on which the component to be supported, for example a shaft, is guided.
  • the bearing material was applied the tread of a bearing component so far by pouring or spinning.
  • the invention is based on the knowledge that this application of the bearing material can lead to binding errors. These binding errors result e.g. B. from bubbles or cavities in the bearing material.
  • the bearing material is applied to the running surface of the bearing component by means of a laser beam.
  • dovetail grooves can be dispensed with in the bearing component. This reduces both the manufacturing effort and the material requirement for bearing material.
  • damage to the tread coating can be easily repaired by local application of the bearing material with the addition of heat.
  • the tread is preferably heated by the laser beam to such an extent that the bearing material forms a material connection with the tread.
  • a cohesive connection corresponds to an alloying of the bearing material to the bearing component.
  • a boundary layer is thus formed between the bearing component and the bearing material, which consists of an alloy of the bearing material with the base material of the tread.
  • Such an alloying of the bearing material to the running surface results in a particularly good connection of the bearing material.
  • the laser beam preferably heats the running surface locally in a heating spot, the bearing material being applied to the heating spot.
  • the laser beam is further preferably guided line by line over the running surface. This process can be automated well. Furthermore, certain construction elements, such as holes or bevels, can be processed in one step using laser technology.
  • the laser beam is preferably guided over the running surface in such a way that the tread is smoothed by remelting of the bearing material.
  • Applying the bearing material by means of the laser beam can result in humps forming along the guide of the laser beam, so that the tread - now formed by the bearing material - has a groove structure. Since the laser beam is preferably guided across the tread surface after line-by-line application, the re-melting, cell-shaped humps in the bearing material align with one another. The tread is smoothed.
  • a white metal is preferably applied as the bearing material.
  • White metals are lead-tin-based alloys.
  • the lead-rich alloys contain e.g. 10% by weight of tin, 15% by weight of antimony, 1% by weight of copper and the rest of lead.
  • a tin-rich alloy contains e.g. 80% by weight of tin, 12% by weight of antimony, 6% by weight of copper and the rest of lead. These alloys meet the basic requirements for a bearing material particularly well.
  • the bearing component is preferably a liner.
  • the bearing component is preferably a bearing shell.
  • a bearing shell of a bearing for a turbomachine shaft is further preferably coated with the bearing material.
  • the object directed to a bearing component is achieved by a bearing component with a base material and with a bearing material applied to the base material, the bearing material being applied in rows by means of a laser beam.
  • the bearing component thus has a line-like structure in the bearing material which can be uniquely assigned to the line-like local melting using a laser beam.
  • the bearing component is preferably part of a bearing of a turbomachine shaft.
  • the bearing material is preferably a white metal.
  • FIG. 1 shows the application of a bearing material to a bearing shell using a laser beam
  • FIG. 2 shows the method from FIG. 1 in a top view
  • FIG. 3 shows the method from FIG. 2 in an enlarged illustration in a longitudinal section
  • FIG. 4 the smoothing of a bearing material applied line by line
  • FIG 5 shows a section of a cross section through a bearing component
  • Figure 6 shows a liner
  • FIG. 1 shows a longitudinal section through a bearing component 1 designed as a bearing shell with a running surface 2.
  • a body (not shown) that is to be supported lies against the running surface 2, for example a shaft.
  • the bearing shell 1 can be rotated by means of the roller 25.
  • a laser beam 23 from a laser 21 strikes the running surface 2 of the bearing shell 1.
  • the heating spot 31 At the point of incidence of the laser beam 23 on the running surface 2, the heating spot 31, a wire material 13 is melted from a wire 13.
  • the bearing material 15 is thereby alloyed to the tread 2.
  • the bearing shell 1 is rotated by means of a roller 25, so that the laser beam 23 is guided in a cell shape over the running surface 2. This is explained in more detail with reference to FIG. 4.
  • FIG. 2 shows a top view of the arrangement in FIG. The laser beam 23 is guided along the feed direction 14. Bearing material 15 is melted from the wire 13 in the heating spot 31 of the laser beam 23.
  • FIG. 3 shows a further possibility of applying bearing material 15 to the running surface 2 of a bearing shell 1 by means of a laser beam 23.
  • the laser beam 23 strikes the running surface 2 of the bearing shell 1 in a heating spot 31.
  • the bearing material 15 is introduced into the heating spot 31 in powder form by means of a nozzle 33.
  • the bearing material 15 melts in the heating spot 31.
  • the bearing material 15 is therefore applied line by line to the bearing shell 1 with a leading melting lug 35.
  • FIG. 4 shows a longitudinal section through a bearing shell 1, onto which bearing material 15 is applied in a row-like manner.
  • a laser beam 23 is guided over the bearing material 15 in a feed direction 24 directed transversely to the lines formed by bumps 26.

Abstract

On applique un matériau pour paliers (15) sur le chemin de roulement (2) d'un élément palier (1), notamment destiné à un palier de turbomachine, à l'aide d'un faisceau laser (23). On obtient ainsi une meilleure adhérence du matériau pour paliers (15) sur l'élément palier (1) et donc une durée de vie prolongée de l'élément palier (1).
