Abstract: PROBLEM TO BE SOLVED: To provide a method of at least partially filling a keyway in a metal sleeve 8 of a rolling mill oil film bearing. SOLUTION: The method comprises a step of machining a pocket into the keyway. A metal key 16 has a shape complementary to that of the pocket with at least one external dimension exceeding each internal dimension of the pocket. The key 16 is thermally shrunk to reduce at least one external dimension to be sufficiently adaptable to insert the key 16 into the pocket. The thermally shrunk key 16 is then inserted into the pocket, and an interference fit is formed between the key 16 and the pocket by thermal expansion. COPYRIGHT: (C)2008,JPO&INPIT
