标准摘要
[中文适用范围]： 本文件规定了符合ISO 3601-1标准的A类O型密封圈的密封槽尺寸，以及用于特定公制尺寸硬件（如液压缸孔和活塞杆）的B类O型密封圈的密封槽尺寸。这些O型密封圈适用于一般液压和气动应用，无论是否使用防挤出环（背环）。O型密封圈的尺寸（d1和d2）、尺寸代码（SC）及公差均符合ISO 3601-1标准。本文件还考虑了不同行业中的设计方法，这在硬件尺寸的表格结构中有所体现。以O型密封圈为起点设计最佳硬件尺寸的方法在表3、表5和表8中有所反映。而以固定硬件尺寸（即孔/杆）为基础并选择最适合的O型密封圈的方法则在表4和表6中有所体现。用于航空航天应用的O型密封圈的密封槽尺寸（在ISO 3601-1中规定的）在附录A中有所说明。注1：特殊应用的O型密封圈密封槽尺寸应由O型密封圈制造商与用户协商确定。注2：本文件中，“密封槽”一词用于描述O型密封圈所装配的凹槽或腔体，以及与之配合的表面，这两者共同限制O型密封圈的运动。 [外文原描述]： This document specifies the housing dimensions for class A O-rings for general industrial applications conforming to ISO 3601-1, as well as housing dimensions for class B O-rings used on selected metric-dimensioned hardware, e.g. fluid power cylinder bores and piston rods. These O-rings are for use in general hydraulic and pneumatic applications without and with anti-extrusion rings (back-up rings). The dimensions of the O-rings (d1 and d2), size codes (SC) and tolerances conform to ISO 3601-1. This document also addresses different design approaches in industry, and this is reflected in the table structures for hardware dimensions. Using the O-ring as a starting point to design the optimal hardware dimensions is reflected in Tables 3 , 5 , and 8 . Using fixed hardware dimensions (i.e. bore/rod) and choosing the most appropriate O-ring to fit is reflected in Tables 4 and 6 . Housing dimensions for the O-rings intended for aerospace applications that are specified in ISO 3601-1 are addressed in Annex A . NOTE 1 It is expected that O-ring housing dimensions for special applications be agreed upon between the O-ring manufacturer and the user. NOTE 2 The term “housing”, in this document, is used to describe the groove or cavity, into which the O-ring is fitted, and the mating surface, which between them confine the O-ring.
