防滑螺母

防滑螺母.jpg

钢丝螺套简称“丝套”,是一种新型的螺纹连接元件,是由高强度,高精度的耐腐蚀菱形不锈钢丝精制而成形如弹簧,旋入特定加大的专用螺孔内,其内表面形成新的螺孔,与螺钉(螺栓)配合时,可明显提高连接强度和耐磨性,特别在铝、镁、铸铁、塑料等低强度材料上。同时,改善了螺纹的受力情况,形成了弹性连接,消除了内外螺纹之间的螺距和牙型半角误差,使螺纹上的负荷均匀分布,保护了基体螺纹不被损坏,延长使用寿命。钢丝螺套由于优良的抗腐蚀、抗高温、抗磨损性能使之能在多种环境下确保其适用性,防止了螺纹锈死、卡死、脱扣现象发生。

     钢丝螺套还可以作为修复手段,在内螺纹脱扣或乱牙时,使其快速有效地修复到原状,各项性能均优于攻丝形成的螺纹。

目前,国外钢丝螺套技术广泛用于航天、航空、船舶、兵器工业、光学仪器、无线电等各类仪器仪表。同时, 大型机车机组汽车制造、冶金、电力、机械、化纤、化工等行业都广泛采用。

丝套安装后形成螺孔的公差带取决于丝套型面制造公差和丝套安装孔螺纹的公差带,主要取决于丝套安装孔的螺纹公差,即安装孔的攻丝精度,也就是专用丝锥的精度,通常达6H,精度高时可达5H,4H级公差带,使用者可以根据所需公差带选择丝锥和攻丝方法及润滑方式等,以达到所需要求。

The profile of the thread insert

   The thread insert is a kind of screw connecting component witch consist of diamond-section stainless material with high strength and accuracy and corrosive resistance.Particularly adopted for soft materials such as aluminum,magnesium,cast iron,palstic,it improves the connecting strength and wear resistance when it is fit with nut after screwed into tapping .ln the meantime,thanks to its elasticity strains are distributed along the whole thread length,by smoothing out unevenness in pitch and angle in thread walls.it makes screw load uniformly and prolongs it the life span.The thread insert may repair effectively these internal threads damaged,its all characteristic excel those tapping holes!

Now,the technique of the outside thread insert is widely used in aerospace aviation,shipbuilding military automotive metallurgy,chemical industries and so on.

The tolcromlc rcmge of the take hole formed by the thread insert is decided by the manufacture,tolerance of the moulding surface of the thread insert and the tolcramce range of the mounting hole,the latter is central,which is also the threading forecision of the mounting hole,which is the accurany of the special tap,usually to the tolcrance range of the 6H class,sometimes to 5Hor 4H class,with high accuranly,the users may slelect the tap,threading means and lubricate manner based on the needed tolerance range.
