A method for producing an internally structured slide bearing bushing involves the following steps:
a) providing a slide bearing bushing with at least one bearing region which is formed as a hollow cylinder with an internal surface and which has an external diameter and an internal diameter,b) providing an external tool with a through-opening,c) providing an internal tool which has an integral cylindrical operating region with an external surface with a structure,d) inserting the internal tool into the bearing region of the slide bearing bushing,e) introducing the slide bearing bushing and the internal tool into the conical widened portion of the through-opening of the external tool,f) pressing the slide bearing bushing into the through-opening of the external tool,g) removing the slide bearing bushing from the through-opening of the external tool, andh) radially widening the slide bearing bushing. |

1. Method for producing an internally structured slide bearing bushing comprising the following successive method steps:
a) providing a slide bearing bushing with at least one bearing region which is formed as a hollow cylinder with an internal surface and which has an external diameter and an internal diameter, b) providing an external tool with a through-opening, the smallest internal diameter thereof being smaller than the external diameter of the bearing region of the slide bearing bushing provided, wherein the through-opening on at least one side has a conical widened portion, the maximum internal diameter thereof being larger than the external diameter of the bearing region of the slide bearing bushing provided, c) providing an internal tool which has an integral cylindrical operating region with an external surface with a structure, wherein the maximum external diameter of the operating region is smaller than the internal diameter of the bearing region of the slide bearing bushing provided, d) inserting the internal tool into the bearing region of the slide bearing bushing, e) introducing the slide bearing bushing and the internal tool into the conical widened portion of the through-opening of the external tool, f) pressing the slide bearing bushing by means of the internal tool into the through-opening of the external tool, reducing the external and internal diameters of the bearing region of the slide bearing bushing, so that the internal surface of the bearing region is pressed onto the external surface of the internal tool and an internal structure is stamped into the internal surface of the bearing region as a negative shape of the structure of the external surface of the internal tool, g) removing the slide bearing bushing from the through-opening of the external tool, h) radially widening the slide bearing bushing so that the internal tool is able to be removed from the slide bearing bushing. |
