1.适用范围 本标准规定了内径为6～200mm的整体铜合金圆桶衬套,翻边衬套的尺寸与公差。 内径是根据已知的轴径和现有的国际标准来选择这类轴承的基本尺寸。 为了提供用其它材料制造滑动轴承与采用尺寸的可能性,允许使用不同强度的材料。本标准包括了两个系列的外径尺寸。 本标准适用于一般用途的衬套;其中较厚的衬套常用于特殊场合。 2.参考标准 ISO/ R286: ISO极限和配合制系统-第一部分:总则、公差和偏差 ISO/ R468:表面粗糙度 ISO/ R775:圆柱和1/10圆锥轴端 ISO2340:U形销-公制系列 ISO2341:带头U形销-公制系列 ISO2795:烧结材料制滑动轴承尺寸与公差 ISO3547 滑动轴承卷制衬套尺寸、公差和检验方法 3.符号(见图1.2) D-衬套外径 e-止推边厚度
1. Scope This standard specifies the overall diameter of 6 ~ 200mm copper alloy drum bushing, flange bushing dimensions and tolerances. The inner diameter is based on the known shaft diameter and the existing international standards to choose the basic dimensions of such bearings. In order to provide the possibility of using other materials for the production of plain bearings and the use of dimensions, the use of materials of different strengths is permissible. This standard includes two series of outer diameter size. This standard applies to general purpose bushings; thicker bushings commonly used in special occasions. 2.
