Title: Sliding bearing
Inventor: KATAGIRI TAKESHI
IPC: F16C17/02
Filed: 2002-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To prevent occurrence of partial early fatigue of a sliding bearing.  <P>SOLUTION: A back plate 21 of portions A, B, C making contact with a part large in rigidity of a housing is thinned and a bearing alloy 22 is thickened on the sliding bearing to be mounted on a large end part of a connecting rod. Consequently, rigidity of the portions A, B, C is lowered, and when oil film pressure at the portions becomes higher as a large load works on the portions, a surface of the bearing alloy 22 is recessedly deflected and deformed by the oil film pressure. As a result, the oil film pressure is extensively dispersed and lowered, and the early fatigue is prevented.  <P>COPYRIGHT: (C)2004,JPO
