Title:

METHOD OF PRODUCING CONNECTING ROD WITH BEARING, AND CONNECTING ROD WITH BEARING

Document Type and Number:

WIPO Patent Application WO/2006/059595

Kind Code:

A1

Abstract:

A method of producing a connecting rod with a bearing, in which both a process for producing a bearing separately from a connecting rod and a process for assembling the bearing to the connecting rod can be eliminated to reduce processes, labor, and costs to produce the connecting rod. A hollow cylindrical molding (38) of a bearing metal material is inserted and fitted, as an inner member, inside the inner surface of a circular large end hole (18) of a large end section (12) of a connecting rod (10). A tapered surface (30) of a rotary pressing tool (26) is pressed, while rotating, to the hollow cylindrical molding (38) to heat and soften the hollow cylindrical molding (38), causing the hollow cylindrical molding (38) of a bearing metal material to plastically flow axially and radially outward, thereby a bearing metal layer (22) is directly joined and formed on the inner surface of the large end hole (18).
