PROCESS FOR PRODUCING A SLIDING BEARING LOCATION IN A CAST COMPONENT WHICH IS PREFERABLY DESIGNED AS A TENSIONING LEVER OF A BELT TENSIONER, AND CAST COMPONENT ITSELF

摘要

A process for producing a sliding bearing bush (4) in a cast component composed of lightweight metal, preferably a tensioning lever (1) of a belt tensioner, comprising the following steps: a die which forms the seat for a sliding bearing bush (4) to be pressed in and has radially outer groove drawing noses is inserted into a lightweight metal pressure die-casting die. After the liquid lightweight metal has been injected into the lightweight metal pressure die-casting die and subsequently solidified, the die is then drawn out of the lightweight metal pressure die-casting die in such a way that an aperture (5) provided with a groove profile is formed as a seat for the sliding bearing bush (4) to be pressed in.
