초록 ▼

A process of manufacturing a member formed with a shaft-receiving opening in that a compact formed with a through hole and comprising a sinterable powder is subjected to liquid-phase sintering is improved in that a bushing, which is made of a material produced by fusion metallurgy and is dimensionally stable under the conditions under which the compact is to be sintered, is inserted into the through opening of the compact with a play which is smaller than the extent of the unrestrained radial shrinkage of the compact at its through opening during its liquid-phase sintering, and the compact is subjected to liquid-phase sintering after the bushing has thus been inserted.

대표청구항 ▼

In a process of manufacturing a member having a shaft-receiving opening, in which a sinterable compact formed with a through opening and comprising a sinterable powder is subjected to liquid-phase sintering under predetermined sintering conditions, under which said compact has a predetermined radial shrinkage at said through opening, the improvement comprising the steps of inserting into said through opening a bushing which is dimensionally stable under said sintering conditions and consists of a material produced by fusion metallurgy, the bushing being so dimensioned that the play between said bushing and said compact is smaller than the extent of said unrestrained radial shrinkage, and then subjecting said compact to said liquid-phase sintering while said bushing is inserted in said compact.
