Problems solved by technology

[0009] On the other hand, in the method (2) disclosed for the purpose of solving the above-mentioned problems in the method (1), it is necessary to recreate the lost model and embed the model by sand molding every time, and, Since runners and risers, which are indispensable in sand casting, cannot be commercialized, there is a problem that it is difficult to say that it is an efficient and inexpensive manufacturing method.

Embodiment

[0030] Specific embodiments of the present invention will be described based on the drawings.

[0031] This embodiment is a manufacturing method based on vertical centrifugal casting, figure 1 (a)~ figure 1 (j) is a process chart showing the manufacturing process in time series.

[0032] As the first process diagram figure 1 (a) is a cross-sectional view of the inner cylinder 1 used for assembling the solid lubricant. On its peripheral wall 2, it matches the embedding pattern of the solid lubricant in the solid lubricant-embedded composite sliding bearing product to be manufactured A through hole 3 for embedding and fixing the solid lubricant 4 is opened. As the material of the inner cylinder 1, any material that can withstand repeated use at high temperatures is sufficient. In this embodiment, an S45C round tube machined to a size of 40 mm in outer diameter, 30 mm in inner diameter, and 95 mm in height is used. 40 through-holes 3 with a diameter of 8 mm are opened in the perip...

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.

Description

Technical field [0001] The present invention relates to a method for manufacturing a sliding member in which a solid lubricant is embedded in a metal base, that is, a composite sliding bearing embedded with a solid lubricant for supporting a shaft on its inner peripheral surface so as to be rotatable. Background technique [0002] As a composite sliding bearing embedded with a solid lubricant, known image 3 As shown, for example, a graphite-based solid lubricant is embedded and fixed in a metal base of a round tube made of a copper-based or iron-based alloy. As a method of manufacturing such a type of composite sliding bearing embedded with a solid lubricant, there are the following methods (refer to Patent Document 1 and Patent Document 2): (1) In a round tube manufactured by continuous casting or extrusion, etc. On the metal substrate, a predetermined shape / a predetermined number of solid lubricant embedding holes are opened by mechanical processing, the solid lubricant is embe...
