SAEJ1199公制外螺紋鋼制緊固件機(jī)械性能與材料要求中文版

1、Mechanical and Material Requirements for Metric Externally Threaded Steel Fasteners公制外螺紋鋼制緊固件機(jī)械性能與材料要求1. Scope 范圍1.1 This SAE Standard covers the mechanical and material requirements for eight property classes of steel, externally threaded metric fasteners in sizes M1.6 through M36, inclusive,

2、and suitable for use in automotive and related applications. 本SAE 標(biāo)準(zhǔn)涵蓋汽車及相關(guān)工業(yè)使用，尺寸在M1.6到M36鋼鐵外螺紋緊固件的八個性能等級的機(jī)械性能與材料要求。1.2 Products included are bolts, screws, studs, U-bolts, preassembled screw and washer assemblies (sems), and products manufactured the same as sems except without washer. 產(chǎn)品包括：螺栓、螺釘、

3、螺柱、U型螺栓、預(yù)裝配的螺釘和墊片組件以及與預(yù)裝配組件一樣加工的無墊圈產(chǎn)品。1.3 Products not covered are tapping screws, thread-rolling screws, and self-drilling screws. Mechanical and material requirements for these products are covered in other SAE documents. 產(chǎn)品不包括自攻螺釘、自擠螺釘、鉆尾螺釘。這些產(chǎn)品的機(jī)械性能與材料要求包含在SAE另外的標(biāo)準(zhǔn)中。1.4 The term stud as ref

4、erred to herein, applies to a cylindrical rod of moderate length, threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared, or similar products which are more closely characterized by requirements shown herein for bolts. 螺柱這里是指適用于中等長度圓

5、柱桿，螺紋在一端有或兩端都有，或全螺紋的產(chǎn)品。它并不適用于有頭的、帶定位的或類似于本文中所要求的螺栓特性近似的產(chǎn)品。1.5 For specification purposes, this document treats U-bolts as studs. Thus, wherever the word studs appears, U-bolts is also implied. U-bolts covered by this document are those used primarily in the suspension and related areas of

6、vehicles. (Designers should recognize that the U configuration may not sustain a load equivalent to two bolts or studs of the same size and grade; thus actual load-carrying capacity of U-bolts should be determined by saddle load tests.) 為了規(guī)范，本標(biāo)準(zhǔn)將U型螺栓是為螺柱。因此，本文中涉及到的螺柱要求，U型螺栓同樣適用。本文所提及的U型螺栓是使用于車輛

7、懸掛位置或相關(guān)位置的產(chǎn)品。（設(shè)計者應(yīng)了解到同樣尺寸、等級的U型螺栓與兩個螺栓或螺柱的載荷是不相等的，因此，U 型螺栓的實(shí)際承載應(yīng)以鞍型荷重測試方法來判定。2 References 參考資料2.1 Applicable Publications The following publications form a part of this specification to the extent specified herein. Unless otherwise indicated, the latest issue of SAE publications shall apply. 適用
