垫圈和缩减垫圈的紧固件零件标准(英制尺寸规格

[中文适用范围]： 本 SAE 零件标准涵盖根据美国机械工程师协会尺寸标准制造的选定英制尺寸垫圈和锁紧垫圈。该 SAE 标准涵盖了船舶系统和设备中最常用的材料，但其用途可适用于使用所涵盖材料的垫圈的任何地方。本标准允许通过本标准中定义的识别号 (PIN) 的一部分来识别和订购垫圈。本文件的目的是帮助设计人员和其他人员提供最常用垫圈和锁紧垫圈的要求和零件或识别号。所有军事应用通常都需要零件或识别号 (PIN)，并且提供了一种以非常简洁的方式向供应商和制造商传达垫圈和锁紧垫圈要求的有用方法。 [外文原描述]： This SAE Part Standard covers selected inch dimensioned washers and lock washers manufactured in accordance with American Society for Mechanical Engineers dimensional StandardDetails. This SAE standard covers material most often used in ship systems and equipment but its use may be applied wherever washers of the covered materials are used. This standard permits the washers to be identified and ordered by a part identification number (PIN) as defined in this standard.Appendix A provides a means of establishing PINs for non-standard flat washers.Appendix B establishes StandardDetails for lock plates and tab lock washers often used in Navy designs.Appendix C identifies other military and non-government StandardDetails for flat washers, helical and toothed lock washers. It identifies the materials covered by each standard with a comparison of those dimensions with those SAE J2655 washers.Cross Reference: AMS2412,AMS2485,AMS2487,AMS2488,ASME B18.18.2,ASME B18.2.6,ASME B18.21.1,ASME B18.22.1,ASTM A 342/1 342M,ASTM B 695,ASTM F 1136,ASTM F 1137,ASTM F 1470,ASTM F 1941,ASTM F 436,ASTMA380,ASTMB580,ASTMD4066,J2280_202112,MIL-DTL-16232,QQ-N-286
