초록 ▼

A method of designing and manufacturing a bearing pin having an external bearing pin geometry includes generating a first pin model conforming to the external bearing pin geometry. One or more operational loads to be applied to the bearing pin are then simulated on the first pin model to identifying at least one first internal region of the first pin model in which at least one of stress, strain, and displacement are below a first predetermined limit. The method further includes generating a final pin model based on the first pin model by forming a first void by removing the at least one first internal region from the first pin model. The bearing pin is then manufactured in accordance with the final pin model.

1. A bearing pin comprising: a bearing pin body comprising: a first internal region having a first density;at least one second internal region having a second density, wherein the second density is less than the first density; andan annular sleeve and a central pin extending axially through said annular sleeve, wherein said annular sleeve comprises said at least one second internal region. 2. The bearing pin in accordance with claim 1, wherein said at least one second internal region comprises a void defined by said bearing pin body. 3. The bearing pin in accordance with claim 2, wherein said at least one second internal region further comprises at least one reinforcing member extending through said void. 4. The bearing pin in accordance with claim 2, wherein said at least one second internal region further comprises a lattice disposed within said void. 5. The bearing pin in accordance with claim 1, wherein said first internal region comprises a first material having the first density and said at least one second internal region comprises a second material having the second density. 6. The bearing pin in accordance with claim 1, wherein said at least one second internal region comprises a metal foam. 7. The bearing pin in accordance with claim 1, wherein said bearing pin body further comprises: a forward end;an aft end axially opposite said forward end; andan annular shoulder disposed between said forward end and said aft end, wherein said annular shoulder comprises said at least one second region. 8. A bearing comprising: a bearing housing;a bearing surface; anda bearing pin extending through said housing, wherein said bearing surface is disposed between said bearing housing and said bearing pin, and wherein said bearing pin comprises: a bearing pin body comprising: a first internal region having a first density;at least one second internal region having a second density, wherein the second density is less than the first density; andan annular sleeve and a central pin extending axially through said annular sleeve, said annular sleeve comprising said at least one second internal region. 9. The bearing in accordance with claim 8, wherein said at least one second internal region includes a void defined by said bearing pin body. 10. The bearing in accordance with claim 9, wherein said at least one second internal region comprises at least one of: a reinforcing member disposed within said void;a lattice disposed within said void; anda metal foam disposed within said void. 11. The bearing in accordance with claim 8, wherein said bearing pin body further comprises: a forward end;an aft end axially opposite said forward end; andan annular shoulder disposed between said forward end and said aft end, wherein said annular shoulder comprises said at least one second internal region.
