Title:
METHOD OF MANUFACTURING COMPOSITE BUSH BEARING EMBEDDED WITH SOLID LUBRICANT
Document Type and Number:
WIPO Patent Application WO/2010/119767
Kind Code:
A1
Abstract:
Provided is a solid lubricant enveloped casting material efficiently and inexpensively in order to eliminate the process for boring a hole to be embedded with a solid lubricant in the metal base of a round pipe, and embedding and securing the solid lubricant in the hole with adhesive interposed therebetween when a composite bush bearing embedded with solid lubricant is manufactured. Molten metal (13) is supplied by centrifugal casting to a cylindrical air gap (11) formed between the inner circumferential surface of a mold (5) and the outer circumferential surface of an inner tube (1) where a solid lubricant (4) is embedded while projecting to the outer circumferential surface incorporated in the inner space of the mold, and a cylindrical solidification layer of the metal where the solid lubricant is enveloped by casting and compounded is formed in the air gap, thus a solid lubricant enveloped casting material is obtained.
