AN IMPROVED PROCESS AND DEVICE OF BONDING OF BABBITT METAL ON A SUBSTRATE OF PRODUCE BABBITTED BEARIING

摘要

This invention relates to a process and device of bonding of babbitt metal on a substrate to produce babbitted bearing by pouring molten babbitt metal in the molding space (8 and 10) in a bearing shell assembly (S) to form an integrated bonding of the babbitt metal with a HP liner (7) on directional solidification of the said metal to form an edge defect free bonding (8) with the HP liner circumferentially at the inner side of the bearing surface of the HP liner and also at the edges of the bearing shell (HP liner) by forming a collar (10). The bearing shell is attached to fixture plates (6) at both side and the bearing shell assembly is fixed on a centrifugal casting machine, wherein the molten metal is poured in the integrated molding space (8 and 10) of the preheated bearing shell assembly through preheated ladle to form a babbitted bonding of the HP liner on solidification on cooling.
