1、应用范围 本国际标准规定一般用途的,与ISO3547所规定的卷制衬套一起使用的止推垫片的一个范围。 本标准适用于内径从6至80mm的止推垫片。 注、本标准所列出的尺寸在市场上不一定都有供应,但采用本标准的尺寸将导致工具成本的降低。 2、有关标准 ISO3547-滑动轴承-卷制衬套-尺寸,公差与检验方法。 3、定义 环形止推垫片:不剖分的圆环,通常装在轴承座的凹座内,用于承受旋转轴的轴向推力和轴向定位（见图1）。 1 Scope of application This International Standard specifies a range of general purpose thrust washers for use with a roll bushing as specified in ISO 3547. This standard applies to the diameter from 6 to 80mm thrust washer. Note that the sizes listed in this standard may not always be available in the market, but the use of the standard dimensions will result in lower tool costs. 2, the standard ISO3547 - plain bearings - roll bushing - dimensions, tolerances and test methods. 3, the definition of annular thrust washer: Non-segmented ring, usually mounted in the bearing seat recess for axial thrust to withstand axial and axial positioning (see Figure 1).
