Abstract (en)
[origin: EP2738377A2] Producing cylinder crankcase (10) comprising wet- and hanging bushes (16), comprises closing a casting mold, introducing at least one steel sleeve into the casting mold for forming at least one cylinder chamber (14), filling the casting mold with a molten metal, extending the steel sleeve after solidification of the melt, opening the mold, removing the cylinder crankcase from the casting mold, and inserting a wet hanging bush into the respective cylinder chambers. The sidewalls bounding the cylinder chamber, before inserting the bushes, are mechanically processed. Producing cylinder crankcase (10) comprising wet- and hanging bushes (16), comprises (a) closing a casting mold, (b) introducing at least one steel sleeve into the casting mold for forming at least one cylinder chamber (14), (c) filling the casting mold with a molten metal, (d) extending the steel sleeve after solidification of the melt, (e) opening the mold, (f) removing the cylinder crankcase from the casting mold, and (g) inserting a wet hanging bush into the respective cylinder chambers formed by the steel sleeve. The sidewalls bounding the cylinder chamber, before inserting the bushes, are mechanically processed, in which a first section of larger diameter is produced between a second axial section of smaller diameter and a third axial section of smaller diameter, which are formed by the steel sleeve.
