1.适用范围 本国际标准为用于往复机械的薄壁翻边轴瓦规定了主要尺寸范围和公差。不能期望从毛坯开始所有表列的主要尺寸都是有用的,但选用标准尺寸能使加工装置成本降低。 本标准所规定的一系列薄壁翻边轴瓦的主要尺寸和公差,适用于轴承座孔(内径)直径为40～～250mm的轴瓦,很少用于较大或较小内径的翻边轴瓦。 本标准对薄壁翻边轴瓦的特定部位也规定了尺寸和公差。对某一部位采用特殊的设计取决于使用者的经验。
1. Scope This International Standard specifies the main dimensional range and tolerances for thin flanged bushings for reciprocating machinery. It is useful to expect that the major dimensions of all the listed rows from the blank will not be useful, but the use of standard sizes will result in lower processing equipment costs. This standard specifies the main dimensions and tolerances of a series of thin-walled flanged bushings, suitable for bearing housing hole (ID) 40 ~ 250mm diameter bearing, rarely used for larger or smaller diameter flanged bearing. This standard also specifies the size and tolerances for the specific location of thin flanged bush. Using a particular design for a site depends on the user’s experience.
