Plain bearing and method for producing the same

1. A plain bearing, comprising:

a single bearing base body made from a single metallic material;

an intermediate layer made from a second metallic material applied directly onto the bearing base body comprising one of an arrangement of wires, a perforated plate and an open-celled metal foam, wherein the arrangement of wires or the perforated plate forms undercuts;

one of a copper film coated on both sides with solder to solder the single bearing base body to the intermediate layer or an adhesive layer to bond the intermediate layer onto the bearing base body; and

a plain-bearing layer made from polyether ether ketone applied onto the intermediate layer.

2. The plain bearing according to claim 1 , wherein the arrangement of wires is one of a wire fabric, a wire mesh, and a knitted wire fabric.

3. The plain bearing according to claim 1 , wherein the plain-bearing layer made from polyether ether ketone is melted onto the one of the arrangement of wires, the perforated plate, and the open-celled metal foam.

4. The plain bearing according to claim 1 , wherein the arrangement of wires are formed from at least one of steel, high-grade steel, and copper.

5. The plain bearing according to claim 1 , wherein the arrangement of wires comprises wires made from different metallic materials.

6. The plain bearing according to claim 1 , wherein the arrangement of wires of the intermediate layer are galvanically coated.

7. The plain bearing according to claim 1 , wherein the single metallic material is steel.

8. The plain bearing according to claim 1 , wherein the solder is a silver alloy solder.

9. A plain bearing, comprising:

a single bearing base body made from a single metallic material;

a plain-bearing layer made from a non-metallic material; and

a surface of the bearing base body has undercuts configured as threads,

wherein the plain-bearing layer is formed as a layer made from polyether ether ketone applied directly onto the bearing base body in the region of the surface forming the undercuts.

10. A method for producing a plain bearing comprising:

providing a single bearing base body made from a single metallic material;

applying an intermediate layer made from a second metallic material, which is constructed as one of an arrangement of wires, a perforated plate, and an open-celled metal foam directly onto the bearing base body;

one of soldering the single bearing base body to the intermediate layer using a copper film coated on both sides with solder or adhesively bonding the intermediate layer onto the bearing base body; and

applying a plain-bearing layer, which is formed from polyether ether ketone, onto the intermediate layer.

11. The method according to claim 10 , wherein

the plain-bearing layer is melted onto the one of the arrangement of wires and the perforated plate.

12. The plain bearing according to claim 10 , wherein the solder a silver alloy solder.

13. A method for producing a plain bearing comprising:

providing a single bearing base body made from a single metallic material;

introducing undercuts into a surface of the bearing base body configured as threads; and

applying a plain-bearing layer, which is formed as a layer made from polyether ether ketone, directly onto the surface of the bearing base body forming the undercuts.

14. The method according to claim 13 , wherein one of:

the undercuts on the surface of the bearing base body are constructed by at least one of milling, blasting, laser processing, or spark erosion; and

the plain-bearing layer made from polyether ether ketone is melted onto the surface of the bearing base body forming the undercuts.
