Abstract

PURPOSE: To produce a bearing metal of good quality and accuracy by a simple technique by packing powder for bearing alloy in the clearance between a cylindrical back metal and a core jig of a coefft. of expansion higher than that of this inserted to the bore of said metal, heating these in this state and sintering the same compactly.
CONSTITUTION: A back metal 1 is disposed concentrically on the outside circumference of a core jig 2 of a coefft. of expansion higher than that thereof. Powder 4 for bearing alloy is packed in the annular clearance between the inside circumferential surface 11 of the metal 1 and the columnar outside circumferential surface 27 of the jig 2. Then, the metal 1 and the jig 2 in this state are loaded into a heating furnace and are heated to a required sintering temp. in a reducing or inert atmosphere. As a result, the powder 4 is strongly compressed by the columnar part 23 of the expanded jig 2, and is surely melt-stuck to the inside circumferential surface 11 by this high-temp. compression; in addition, the entire part is consolidated, and is sintered as a bearing alloy 4' of less unevenness on the surface and high density.
