DRY LUBRICANT FILM COMPOSITION AND SLIDE BEARING HAVING DRY LUBRICANT FILM COMPOSITION AS SLIDING LAYER

摘要

PPROBLEM TO BE SOLVED: To provide a slide bearing improving bearing performance, particularly, non-seizure property, initial conformability and cavitation resistance. PSOLUTION: A sliding layer 2 is disposed on a surface of a bearing alloy layer 1 made of copper alloy or aluminum alloy. The sliding layer 2 uses polyamide-imide resin as a main component, and includes resin binder in the form of polymer alloy obtained by adding polyamide resin and applying high-shear, and 1-75 mass% solid lubricant. Therefore, toughness and stiffness are given to the sliding layer 2, and the non-seizure property, initial conformability and cavitation resistance can be improved. PCOPYRIGHT: (C)2009,JPO&INPIT
