Patent attributes
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 of a bearing metal material is inserted and fitted, as an inner member, inside an inner surface of a circular large end hole of a large end section of a connecting rod. A tapered surface of a rotary pressing tool is pressed, while rotating, to the hollow cylindrical molding to heat and soften the hollow cylindrical molding, causing the hollow cylindrical molding of the bearing metal material to plastically flow axially and radially outward, whereby a bearing metal layer is directly joined and formed on the inner surface of the large end hole.
