Title: Sliding bearing
Inventor: SUZUKI MIKIO
IPC: F16C33/08
Filed: 2008-03-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a sliding bearing allowing little intrusion of press-fitting remnants of a coating layer chipped away during press-fitting into a bearing device, a lubricating oil passage and a bearing sliding surface.  <P>SOLUTION: In this cylindrical sliding bearing 1 formed with a bearing alloy layer as the sliding surface on the inside of a steel back metal, the coating layer 2 of Bi or a Bi-based alloy is formed on the outer back surface of the steel back metal. Bi or the Bi-based alloy provides advantages same as those of Sn, Pb or an alloy thereof in terms that it is soft and lowers friction during the press-fitting to enhance the press fitting ability. Since the coating layer has a very low ductility and is less liable to flow plastically, if it is chipped at the end part of a bearing housing 4, it is subjected to brittle fracture, so that the press-fitting remnants become very fine, and does not remain and adhere to the end part of the bearing housing 4. That provides an advantage that the press-fitting remnants are less liable to intrude into the bearing device, the bearing lubricating oil passage and the bearing sliding surface.  <P>COPYRIGHT: (C)2010,JPO&INPIT
