  普通型螺纹护套

  标准:DIN814(普通\自锁型)

  规格:M2-M36,3/16-1”

  材质:304\316,A2\A4

  长(zhang)度说(shuo)明:以螺纹的(de)直(zhi)径(jing)倍(bei)数为单位(wei),1倍(bei)直(zhi)径(jing)的(de)长(zhang)度=1D,例如(ru)M5*2D=5*2=10MM,M6*2.5D=6*2.5=15MM。

  常用规格(ge)有1D,1.5D,2D,2.5D,3D。

  表面处理:本色

  使(shi)用范围: 螺纹(wen)(wen)(wen)(wen)(wen)(wen)护(hu)套(tao)是(shi)一种新型内螺纹(wen)(wen)(wen)(wen)(wen)(wen)紧固件,是(shi)由(you)高(gao)强(qiang)度(du),高(gao)精(jing)度(du)的(de)耐腐蚀菱形不锈钢丝精(jing)制而成(cheng)(cheng),形如(ru)弹簧,安装在(zai)(zai)基本(ben)特定(ding)螺纹(wen)(wen)(wen)(wen)(wen)(wen)孔中,其内表面(mian)形成(cheng)(cheng)标准螺纹(wen)(wen)(wen)(wen)(wen)(wen),与螺钉(螺栓)配合(he)时,可(ke)明显提(ti)高(gao)连接强(qiang)度(du)和耐磨性(xing),特别(bie)在(zai)(zai)铝、镁、铸铁、塑料(liao)等(deng)低强(qiang)度(du)材料(liao)上。同时,改善(shan)了(le)(le)螺纹(wen)(wen)(wen)(wen)(wen)(wen)的(de)内力(li)情(qing)况,形成(cheng)(cheng)了(le)(le)弹性(xing)连接,消除了(le)(le)内外螺纹(wen)(wen)(wen)(wen)(wen)(wen)之间的(de)螺距和牙(ya)型半角(jiao)误差(cha),使(shi)螺纹(wen)(wen)(wen)(wen)(wen)(wen)上的(de)负荷(he)匀分(fen)布,保护(hu)了(le)(le)基本(ben)螺纹(wen)(wen)(wen)(wen)(wen)(wen)不被损坏,延长使(shi)用寿命。螺纹(wen)(wen)(wen)(wen)(wen)(wen)护(hu)套(tao)由(you)于(yu)优良的(de)抗(kang)腐、抗(kang)高(gao)温、抗(kang)磨损,能在(zai)(zai)多种环(huan)境下确保其造用性(xing),防止了(le)(le)螺纹(wen)(wen)(wen)(wen)(wen)(wen)锈死、卡死、脱扣现象发(fa)生。螺纹(wen)(wen)(wen)(wen)(wen)(wen)护(hu)套(tao)还可(ke)以作(zuo)为(wei)修(xiu)复手段(duan),在(zai)(zai)内螺纹(wen)(wen)(wen)(wen)(wen)(wen)脱扣或乱牙(ya)时,使(shi)其快速有效地(di)修(xiu)复到原(yuan)状,各项性(xing)能均优于(yu)攻丝形成(cheng)(cheng)的(de)螺纹(wen)(wen)(wen)(wen)(wen)(wen)。

  目前,螺纹护套技术广泛用(yong)于(yu)适用(yong)于(yu)航天、航空、船舶、兵器(qi)工(gong)业、光学仪器(qi)、无线电等各类仪器(qi)表。同时,大(da)型机车、机组、汽车制造、冶金(jin)、电力、机械、化纤、化工(gong)行业都(dou)广泛采用(yong)。丝套安(an)(an)装(zhuang)(zhuang)后形成螺孔的(de)公(gong)(gong)差(cha)(cha)带(dai)取决于(yu)丝套型面制造公(gong)(gong)差(cha)(cha)和丝套安(an)(an)装(zhuang)(zhuang)孔螺纹的(de)公(gong)(gong)差(cha)(cha)带(dai),主要取决于(yu)丝套安(an)(an)装(zhuang)(zhuang)孔的(de)螺纹公(gong)(gong)差(cha)(cha),即安(an)(an)装(zhuang)(zhuang)孔的(de)工(gong)攻(gong)丝精(jing)度,也就是(shi)专用(yong)丝锥的(de)精(jing)度,通常(chang)达6H级,精(jing)度高时可达5H、4H级的(de)公(gong)(gong)差(cha)(cha)带(dai),使用(yong)者可以根据所需(xu)公(gong)(gong)差(cha)(cha)带(dai)选择(ze)丝锥和攻(gong)丝方法及润(run)滑方式,以达到所需(xu)要求(qiu)。
