    • PURPOSE:To obtain the economical mass production of a sliding bearing with high precision without any mechanical processing by arranging the first layer in an outer mold with a core for shaping optional number of synthetic resin layers around the first layer by injection and finally taking out the core from the first layer. CONSTITUTION:The outer diameter of a core 4 is shaped in consideration of the contracted portion due to shaping, and its surface is processed by precise finishing such as mirror face finishing. The inner surface of an outer mold 5 is roughed by shot-blasting, other mechanical processings, etching, or the like. Synthetic resin 9 is injected into a space 8 to shape the first layer to be used for a bearing layer. When the core 4 with the first layer 1 is arranged in the second outer mold 10 and synthetic resin 12 is injected into a space between the first layer and the outer mold 10 to shape the second layer 2 to be used for a supporting layer, the inner surface of the second layer 2 is roughed to correspond to the rough surface of the periphery of the first layer 1, and as contraction goes on, the first and the second layers are combined tight.
    • 目的:为了通过将第一层布置在外模具中的第一层,通过注射成型可选数量的合成树脂层,最后取出 核心从第一层。 构成:芯4的外径由于成形而考虑到收缩部分的形状,并且其表面通过精加工如镜面整理加工。 外模5的内表面通过喷丸,其它机械加工,蚀刻等粗糙化。 将合成树脂9注入到空间8中,以形成用于承载层的第一层。 当具有第一层1的核心4布置在第二外部模具10中并且合成树脂12被注入到第一层和外部模具10之间的空间中以形成用于支撑层的第二层2时, 第二层2的内表面被粗糙化以对应于第一层1的周边的粗糙表面,并且随着收缩,第一层和第二层被组合紧密。
