Verfahren zum Verbinden von Zylinderbüchsen in Bohrungen eines Motorblocks.

摘要

Method of bonding cylinder liners to cylinder bore walls, comprising: (a) inserting a cylindrical work hardenable liner (10) into a complementary sized cylindrical bore wall (11) of the block, with a uniform annular radial spacing therebetween of about .0125 CM (0.005 inch), and (b) forcing a nondeformable mandrel (14) throughout the interior length of the cylindrical liner to uniformly circumferentially expand the radially outer surface of the liner (10) into full annular surface-to-surface heat exchange relationship with the interior surface of the bore wall, the mandrel (14) having a cross-sectional radius greater than the interior radius of the liner by a dimension which is at least .0025 cm (.001 inch) in excess of such radial spacing.
