我们(men)有(you)许多应用，包括(kuo)定位(wei)(wei)系(xi)统，夹紧系(xi)统，测试和检查设备，蓄电池(chi)和分离器，以(yi)及(ji)取放系(xi)统。一位(wei)(wei)客户需要一个(ge)弹(dan)簧(huang)啮合的(de)空(kong)气(qi)释放制(zhi)动器，其(qi)扭矩在塑料热成(cheng)型机上(shang)承受(shou)885磅的(de)负载(zai)。弹(dan)簧(huang)接合，电动释放的(de)制(zhi)动器无法承受(shou)负载(zai)，负载(zai)由伺服电机和30毫(hao)米直(zhi)径(jing)的(de)滚珠(zhu)丝(si)杠驱动。我们(men)的(de)弹(dan)簧(huang)式空(kong)气(qi)释放制(zhi)动器提供保持力。制(zhi)动器通过弹(dan)性体联(lian)轴器连接到(dao)滚珠(zhu)螺杆的(de)非驱动端。耦合由两半(ban)组成(cheng)。一半(ban)有(you)一个(ge)夹紧轮毂和径(jing)向螺钉，可(ke)以(yi)连接到(dao)滚珠(zhu)丝(si)杠上(shang)。另(ling)一半(ban)具有(you)扩展轴和锥形夹紧元件，用于连接到(dao)制(zhi)动孔。这种设计使联(lian)轴器能(neng)够吸收由滚珠(zhu)丝(si)杠的(de)热膨胀产生的(de)轴向不(bu)对中(zhong)。

螺钉的外表面和螺母的内表面形成为具有互补的螺旋形螺纹，其横截面通常精密滚珠丝杠副厂家为半圆形。但是，螺钉的外径小于通过螺母形成的开口的内径。因此，螺钉的外表面和通过螺母形成的开口的内表面精密滚珠丝杠副厂家不会彼此(ci)接合(he)。而(er)(er)(er)是，多个球(qiu)(qiu)设(she)置在(zai)(zai)螺(luo)(luo)(luo)(luo)(luo)钉(ding)和(he)螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)之间。通(tong)常，螺(luo)(luo)(luo)(luo)(luo)钉(ding)连接到(dao)旋(xuan)转(zhuan)(zhuan)(zhuan)动(dong)(dong)(dong)力源，而(er)(er)(er)螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)被(bei)固定(ding)以(yi)便不可旋(xuan)转(zhuan)(zhuan)(zhuan)。因此(ci)，当螺(luo)(luo)(luo)(luo)(luo)杆(gan)(gan)旋(xuan)转(zhuan)(zhuan)(zhuan)时(shi)，螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)相对于(yu)螺(luo)(luo)(luo)(luo)(luo)杆(gan)(gan)线性移(yi)(yi)动(dong)(dong)(dong)。然(ran)而(er)(er)(er)，在(zai)(zai)某些(xie)情(qing)况(kuang)下(xia)(xia)，螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)被(bei)固定(ding)为(wei)静止，并且螺(luo)(luo)(luo)(luo)(luo)杆(gan)(gan)在(zai)(zai)其(qi)旋(xuan)转(zhuan)(zhuan)(zhuan)时(shi)轴(zhou)向移(yi)(yi)动(dong)(dong)(dong)。在(zai)(zai)一种(zhong)(zhong)情(qing)况(kuang)下(xia)(xia)，由于(yu)滚(gun)珠与螺(luo)(luo)(luo)(luo)(luo)钉(ding)和(he)螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)的(de)(de)滚(gun)动(dong)(dong)(dong)接合(he)，螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)或螺(luo)(luo)(luo)(luo)(luo)钉(ding)的(de)(de)这(zhei)种(zhong)(zhong)线性运动(dong)(dong)(dong)是在(zai)(zai)的(de)(de)摩擦下(xia)(xia)完成的(de)(de)。然(ran)而(er)(er)(er)，当螺(luo)(luo)(luo)(luo)(luo)杆(gan)(gan)旋(xuan)转(zhuan)(zhuan)(zhuan)时(shi)，滚(gun)珠在(zai)(zai)螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)中(zhong)(zhong)形成的(de)(de)螺(luo)(luo)(luo)(luo)(luo)纹(wen)中(zhong)(zhong)滚(gun)动(dong)(dong)(dong)。为(wei)了适应这(zhei)种(zhong)(zhong)情(qing)况(kuang)，已(yi)知提(ti)供一种(zhong)(zhong)允(yun)许球(qiu)(qiu)在(zai)(zai)无端(duan)环(huan)中(zhong)(zhong)从螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)的(de)(de)一端(duan)到(dao)另一端(duan)的(de)(de)装(zhuang)置。该球(qiu)(qiu)装(zhuang)置通(tong)常包括穿过螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)形成的(de)(de)一对孔和(he)在(zai)(zai)孔之间延伸(shen)的(de)(de)外管(guan)。孔径向延伸(shen)穿过螺(luo)(luo)(luo)(luo)(luo)母(mu)(mu)(mu)，与其(qi)中(zhong)(zhong)形成的(de)(de)螺(luo)(luo)(luo)(luo)(luo)纹(wen)的(de)(de)端(duan)部连通(tong)。该管(guan)具有(you)延伸(shen)到(dao)孔中(zhong)(zhong)的(de)(de)端(duan)部。管(guan)的(de)(de)端(duan)部的(de)(de)可以(yi)形成为(wei)具有(you)整体的(de)(de)偏转(zhuan)(zhuan)(zhuan)器，该偏转(zhuan)(zhuan)(zhuan)器将球(qiu)(qiu)引导进出(chu)线。

此外，空气释放(fang)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)具有电(dian)动(dong)(dong)(dong)(dong)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)的(de)优点，因(yin)为(wei)在(zai)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)脱离时不(bu)消耗功(gong)率(lv)。这意味着空气释放(fang)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)节能。它们使(shi)用(yong)大约1.2瓦(wa)来(lai)(lai)为(wei)气动(dong)(dong)(dong)(dong)控制(zhi)(zhi)阀供电(dian)。电(dian)动(dong)(dong)(dong)(dong)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)使(shi)用(yong)线圈来(lai)(lai)保持(chi)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)脱离，消耗功(gong)率(lv)并在(zai)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)内产生热量。过(guo)多的(de)热量会减(jian)少(shao)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)的(de)保持(chi)能力(li)。大多数事故不(bu)是在(zai)正(zheng)常操作(zuo)条(tiao)件下(xia)发(fa)生的(de)，而是在(zai)编(bian)程，维护(hu)(hu)，修理和测试期(qi)间发(fa)生的(de)。因(yin)此，在(zai)执(zhi)行(xing)维护(hu)(hu)任务或部分启动(dong)(dong)(dong)(dong)设备(bei)时，需(xu)要采取适当的(de)措施，线性(xing)运动(dong)(dong)(dong)(dong)轴的(de)负载移动(dong)(dong)(dong)(dong)。即使(shi)在(zai)水平运动(dong)(dong)(dong)(dong)中，许多系统也使(shi)用(yong)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)(qi)(qi)来(lai)(lai)减(jian)少(shao)在(zai)由可移动(dong)(dong)(dong)(dong)装置或其他打开而触发(fa)的(de)机(ji)器(qi)(qi)(qi)停止期(qi)间滑行(xing)。

滚珠(zhu)丝(si)(si)(si)杠副可以(yi)使用(yong)(yong)(yong)(yong)润滑(hua)脂(zhi)(zhi)或(huo)(huo)油润滑(hua)。建议在大(da)多数正常(chang)应用(yong)(yong)(yong)(yong)中(zhong)使用(yong)(yong)(yong)(yong)润滑(hua)脂(zhi)(zhi)。这(zhei)是因为(wei)润滑(hua)脂(zhi)(zhi)不(bu)需(xu)(xu)要(yao)润滑(hua)系统，并且需(xu)(xu)要(yao)比(bi)油少的润滑(hua)脂(zhi)(zhi)。高速(su)应用(yong)(yong)(yong)(yong)或(huo)(huo)需(xu)(xu)要(yao)时可能(neng)(neng)需(xu)(xu)要(yao)油。滚珠(zhu)丝(si)(si)(si)杠用(yong)(yong)(yong)(yong)于(yu)运(yun)(yun)动(dong)(dong)控制，但需(xu)(xu)要(yao)轴(zhou)承支(zhi)撑和(he)(he)电机联(lian)轴(zhou)器才能(neng)(neng)工作(zuo)。通过将滚珠(zhu)丝(si)(si)(si)杠与线性平(ping)台(tai)结合使用(yong)(yong)(yong)(yong)，我们能(neng)(neng)够(gou)为(wei)许(xu)多应用(yong)(yong)(yong)(yong)产生稳定(ding)(ding)的线性平(ping)移。因此，滚珠(zhu)丝(si)(si)(si)杠应用(yong)(yong)(yong)(yong)于(yu)多种行业，从车库(ku)门开启(qi)器到工作(zuo)台(tai)滑(hua)块。滚珠(zhu)丝(si)(si)(si)杠通常(chang)不(bu)用(yong)(yong)(yong)(yong)于(yu)需(xu)(xu)要(yao)小于(yu)球(qiu)直径(jing)的摆(bai)动(dong)(dong)运(yun)(yun)动(dong)(dong)的应用(yong)(yong)(yong)(yong)中(zhong)。这(zhei)种类型的运(yun)(yun)动(dong)(dong)会移除(chu)润滑(hua)层并导(dao)(dao)致错误(wu)增加。这(zhei)可以(yi)使用(yong)(yong)(yong)(yong)较小的滚珠(zhu)丝(si)(si)(si)杠和(he)(he)润滑(hua)脂(zhi)(zhi)来解决(jue)。大(da)多数需(xu)(xu)要(yao)程度的定(ding)(ding)期维护; 但是一些特种球(qiu)螺钉(ding)不(bu)需(xu)(xu)要(yao)维护！导(dao)(dao)轨没有(you)水(shui)，污垢，灰尘和(he)(he)碎屑(xie)等污染物(wu)。
