Patent number: 11434955Abstract: A method of making a powder metal bearing support insert includes filling a tool and die set with a powder metal. A compact is compacted from the powder metal using the tool and die set in which the compact includes a body having a pair of opposing ends on lateral sides thereof, a bearing-receiving surface positioned on a side of the body between the pair of opposing ends in which the bearing-receiving surface is for reception of a bearing therein, and a pair of holes extending through the body wherein each of the pair of holes are formed by sets of adjacent interdigitated slots having regions that abut one another to form a connected passageway therethrough that define the respective hole. The compact is sintered to form the powder metal bearing support insert. The powder metal bearing support insert may be cast into an engine component.Type: GrantFiled: August 26, 2020Date of Patent: September 6, 2022Assignee: GKN Sinter Metals, LLCInventors: Gary R.

Patent number: 10859117Abstract: A powder metal bearing support insert for casting into an engine component includes a pair of holes formed by interdigitated slots during a powder metal compaction process. Since they are formed by interdigitated slots, this pair of holes may receive the cast material therein during the casting step. Among other things, the cast material in these holes may be drilled or machined using tools graded to work the material of the casting in contrast to the material of the insert.Type: GrantFiled: March 7, 2018Date of Patent: December 8, 2020Assignee: GKN Sinter Metals, LLCInventors: Gary R.

Patent number: 8857390Abstract: A method of joining multiple powder metal components to form a powder metal component assembly using an adhesive is disclosed. By machining at least one of the powder metal components prior to the adhesive joining, otherwise difficult to machine features can be more easily machined for less cost and at higher production rates. Unlike high temperature joining techniques, the adhesive joins the powder metal components at room temperature. This room temperature adhesive joining eliminates the thermal distortions in pre-joined machined features common to high temperature joining techniques such as brazing or welding that bring these features out of specification during joining.Type: GrantFiled: June 5, 2009Date of Patent: October 14, 2014Assignee: GKN Sinter Metals, LLCInventors: Gerald Michael Malen, Timothy Costanzo, Ian W. Donaldson, Joel H. Mandel

Patent number: 8336425Abstract: A cast metal connecting rod of the type used in a reciprocating piston engine has a beam section between two end sections. The beam section and the end sections are integral with one another and are at least partially made of a cast metal material. At least the beam section of the connecting rod includes an insert made of a sintered powder metal material. The insert is at least partially encapsulated by the cast metal material of the connecting rod. The insert reinforces the connecting rod and can help match characteristics of surrounding or mating parts of the engine that are made of materials more similar to the material of the insert than the cast metal of the connecting rod. The cast metal material, for example aluminum alloy, of the connecting rod can also provide localized regions of high machinability where needed.Type: GrantFiled: July 19, 2006Date of Patent: December 25, 2012Assignee: GKN Sinter Metals, LLCInventors: Joel H. Mandel, Donald D. Cooper, Carl J. Langraff

Patent number: 8071016Abstract: A method is disclosed of forming a powder metal compact. Powder metal is placed in an annular space of a compaction die tool set in which the annular space has inner and outer cylindrical surfaces that form inner and outer cylindrical surfaces of the powder metal compact. An elastomeric tool has a first cylindrical surface adjacent to a fixed cylindrical surface of the compaction die tool set that is radially fixed and further has a second cylindrical surface, opposite to the first cylindrical surface, that touches the powder metal. The powder metal is compressed to form the powder metal compact by applying an external axial force on the elastomeric tool while maintaining the diameter of the fixed cylindrical surface so as to cause the elastomeric tool to compress the second cylindrical surface of the elastomeric tool against the powder metal.Type: GrantFiled: September 21, 2007Date of Patent: December 6, 2011Assignee: GKN Sinter Metals LLCInventors: Timothy M. Campbell, Joel H. Mandel, Donald J. Phillips, Donald D. Cooper, Henry J. Knott

Patent number: 7987569Abstract: A high performance main bearing cap has particular surfaces densified for improved fatigue crack resistance. The surfaces densified are the bolted face inside of a perimetral margin and outside of bolt head interface areas around the main bolt holes, the surfaces of the main bolt holes and the side bolt hole threads. Preferred methods of densification are single needle programmable pattern peening of the bolted face peened area, over-burnishing of the bolt holes, and forming the threads rather than cutting them for the side bolt threads.Type: GrantFiled: October 22, 2007Date of Patent: August 2, 2011Assignee: GKN Sinter Metals, LLCInventors: Terry M. Cadle, Susan M. Cadle, legal representative, Joel H. Mandel, Donald J. Phillips
