13、九、 钢丝螺套的装配使用过程···························· -18-一、 钢丝螺套简介1、 钢丝螺套及应用 钢丝螺套（Wire Thread Insert），简称丝套，是一种新型内螺纹紧固件。将其镶入金属或非金属材料上形成高强度、耐磨损、具有互换性的标准内螺纹。在铝、镁合金、塑料、密度板等低强

14、度工程材料上应用可明显提高强度和耐磨性；应用在钢件、铸钢、铸铁上，可以提高螺钉的耐用性，防止由于各种振动引起螺钉松动、疲劳断裂及提高螺钉连接时的耐疲劳强度。 在出现螺纹加工错误或对已损坏的内螺孔修复时，使用钢丝螺套作为修复手段，可以不增加重量和体积，获得经济地维修，拯救重要部件，快速有效地修复到原始状态，并可使用原规格螺钉。 利用钢丝螺套进行公制英制螺纹孔转换，非常方便、快速。 钢丝螺套是用高强度、高精度、表面光洁的冷轧菱形不锈钢丝精确成形的螺旋线圈，为高精度内、外螺纹同心体，钢丝螺套装好后能形成一个符合国际标准的高精度内螺纹，其各项性能均优于攻好丝形成的螺纹。钢丝螺套安装后螺孔公差带取决于钢

15、丝螺套型面制造公差和钢丝螺套安装孔螺纹公差带；后者主要取决于钢丝螺套安装孔的攻丝精度，通常形成6H级，精度高时可达5H、4H级公差带。钢丝螺套使用部门可以根据所需公差带选择丝锥和攻丝方法（手攻、机攻）及润滑方式等，以确保达到您的要求。2、钢丝螺套的分类（1）按钢丝螺套材料分类A、不锈钢材料：通过强度和材料的组合，在通常情况下使用，在轻微型结构、铝合金结构、海水、含氯液体、增加抗腐蚀性下使用。B、铜合金材料：在要求用铜的情况下或经常调节转动的螺纹连接时使用；在要求用于导电或自润滑等情况时使用。C、高温合金材料：温度在500750时耐热使用；对宇航装配技术、飞机发动机、内燃机涡轮压气机在750内作

16、业时使用。（2）按钢丝螺套使用功能分类A、普通型钢丝螺套（Free-Running Inserts）记号“FR”B、锁紧型钢丝螺套(Screw Lock Inserts)记号“SL”（3）按钢丝螺套的螺纹体制分类A、国际标准ISO“M，MJ”系列钢丝螺套螺纹系列标记“M”，“MJ”；火花塞螺纹（Spark plug Thread）丝套在此系列B、统一螺纹“UN”系列钢丝螺套(UNIFIED Thread Series)粗牙螺纹标记“UNC”，细牙螺纹标记“UNF”，超细牙螺纹标记“UNEF”C、非螺纹密封的管螺纹(British Standard Pipe Thread)螺纹标记号为“G”（4

17、）按钢丝螺套的旋转方向分类A、右旋钢丝螺套B、左旋钢丝螺套（5）按钢丝螺套安装柄有无分类：A、有安装柄钢丝螺套B、无安装柄钢丝螺套（6）按钢丝螺套表面有无镀层分类A、表面无镀层钢丝螺套B、表面有镀层钢丝螺套 如：镀银、镀镉等。3、钢丝螺套的特点A、 自由状态的钢丝螺套直径比其欲装入的螺孔直径稍大，装配时使钢丝螺套经过安装扳手螺纹引导圈受扭力从而使其直径变小，进入螺孔中，装好以后，钢丝螺套产生类似弹簧膨胀的作用，使其牢固地固定在螺纹孔内，不会因螺钉的旋出而被带出，不会随螺钉的运动而运动。 B、增加螺纹连接的承载能力和疲劳强度：钢丝螺套使螺钉与安装钢丝螺套的螺孔之间形成弹性连接，因而消除了内外螺纹

18、之间的螺距和牙型半角误差，可在规定的长度上使每圈螺纹上的负荷均匀分布，从而加强了内螺纹，并能减振，因此可以提高零件螺纹连接的疲劳强度。 C、耐磨： 钢丝螺套由极硬的冷轧钢丝绕制而成，似镜的表面减少了磨擦和磨损，可使螺钉上由于磨擦而产生的扭力减少90%，从而用最小的旋紧螺钉力矩得到最大予紧力矩和螺钉拉力，防止螺钉松脱，使合金钢螺钉处于最佳使用状态。 D、耐腐蚀：由于钢丝螺套优良的抗腐蚀性能使之能在多种材料和通常环境条件下确保其适用性，使用钢丝螺套的组合件不会滞住。 E、耐热：钢丝螺套在高温下可以阻止螺纹连接卡死或擦伤。 F、与普通标准内螺纹相比，在同样的强度条件下，使用钢丝螺套后，为了尽可能好的

19、利用屈服极限，可选用尺寸较小，强度较高的螺钉，这样就可以大量节约材料，减轻重量和缩小体积。 G、锁紧型钢丝螺套能把螺钉锁紧在钢丝螺套安装后形成的螺纹孔中，在受振和冲击时，可使螺钉不致松扣，比通常锁紧装置工艺性能好。、 钢丝螺套的材料及适用条件 表1材料牌号室温抗拉强度稳定工作温度表面状态适用性和应用示例不锈钢1Cr18Ni9>1400 Mpa425短时间315长时间无镀层通常情况下使用增强抗腐蚀性轻型结构的螺纹摩擦、海水含氯液体1Cr18Ni9Ti表面涂抹润滑00 Cr17Ni14Mo2镀镉镀银铜合金QSn6.5-4>1000 Mpa300短时间250长时间无镀层镀镉用于导电或自润
