Abstract
A number of variations disclosed may include a product which may include a casting having a surface defining a main bearing feed groove and a surface defining at least one oil feed groove, the surface defining the main bearing feed groove and surface defining the at least one oil feed groove intersecting without any sharp corners or edges so that a smooth flow path is defined through the main bearing feed groove and into the at least one oil feed groove.
Claims20
A product comprising:
- a casting having a surface defining a main bearing feed groove and a surface defining at least one oil feed groove, the surface defining the main bearing feed groove and surface defining the at least one oil feed groove intersecting without any sharp corners or edges so that a smooth flow path is defined through the main bearing feed groove and into the at least one oil feed groove.
A method comprising:
- placing a casting core in a casting mold and pouring molten metal into the casting mold;
- allowing the molten metal to cool to form a solidified metal and the form at least a portion of a casting;
- removing the casting core to leave a cavity in the solidified metal configured to receive a bearing;
- forming a main bearing feed groove in the solidified metal communicating with the cavity in the solidified metal, wherein the main bearing feed groove is defined by a main bearing feed groove surface and the cavity in the solidified metal is defined in part by at least an oil feed groove surface, and wherein the main bearing feed groove surface and the at least one oil feed groove surface define an oil flow path free of sharp corners or edges.
1 more element
A product comprising:
- a casting core having an inverse mouth portion including a flat surface having a first end and an opposite second end, a first curved surface connected to a first end of the flat surface so that the first curved surface and the first end of the flat surface form a first corner, and a second curved surface connected to the second end of the flat surface so that the second curved surface and the second end of the flat surface form a second corner, and wherein the first curved surface curves away from a first imaginary line extending perpendicular to the flat surface and intersecting the first corner, and wherein the second curved surface curves away from a second imaginary line extending perpendicular to the flat surface and intersecting the second corner.
