應用領域

1、直(zhi)線導(dao)軌主要用在(zai)自動化(hua)機械上比較多，像德國(guo)進(jin)口(kou)的機床，自動化(hua)設備配件，折彎機，激(ji)光焊接機等(deng)等(deng)，當然直(zhi)線導(dao)軌和直(zhi)線軸(zhou)是配套用的。

2、直(zhi)線導(dao)軌主(zhu)要是用(yong)在(zai)精度要求比較高(gao)的機械結構上(shang)(shang)，直(zhi)線導(dao)軌的移(yi)動元(yuan)件和固定元(yuan)件之間不用(yong)中間介質，而用(yong)滾動鋼球(qiu)。因為滾動鋼球(qiu)適應于高(gao)速運動、摩擦(ca)系數(shu)小、靈(ling)敏度高(gao)，滿足運動部(bu)件的工作要求，如(ru)機床(chuang)的刀架，拖板等。如(ru)果作用(yong)在(zai)鋼球(qiu)上(shang)(shang)的作用(yong)力太大(da)(da)，鋼球(qiu)經受預加負荷時間過長(chang)，導(dao)致支(zhi)架運動阻力增大(da)(da)。

直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)(gui)又被稱為線(xian)(xian)(xian)(xian)性(xing)導(dao)(dao)軌(gui)(gui)、滑(hua)軌(gui)(gui)、線(xian)(xian)(xian)(xian)性(xing)導(dao)(dao)軌(gui)(gui)、線(xian)(xian)(xian)(xian)性(xing)滑(hua)軌(gui)(gui)，用(yong)以(yi)高(gao)精度或快速(su)直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)往(wang)復(fu)運動(dong)場所，且(qie)能夠擔負(fu)一(yi)定的扭距，可以(yi)從高(gao)負(fu)載的情形(xing)下完成(cheng)高(gao)精密(mi)度的勻(yun)速(su)直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)運動(dong)。直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)(gui)可以(yi)分(fen)為：滾(gun)軸直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)(gui)，圓柱(zhu)體直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)(gui)，鋼(gang)0珠直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)(gui)三種，就(jiu)是用(yong)來(lai)支撐(cheng)和正確引導(dao)(dao)健身運動(dong)構件，按給出方向做往(wang)復(fu)式勻(yun)速(su)直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)運動(dong)。依按磨(mo)擦特性(xing)來(lai)定，勻(yun)速(su)直(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)運動(dong)導(dao)(dao)軌(gui)(gui)可分(fen)為滾(gun)動(dong)摩(mo)擦導(dao)(dao)軌(gui)(gui)、滾(gun)動(dong)摩(mo)擦力(li)導(dao)(dao)軌(gui)(gui)、彈力(li)磨(mo)擦導(dao)(dao)軌(gui)(gui)、液體磨(mo)擦導(dao)(dao)軌(gui)(gui)等類型

直(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)（linear slider）又稱線(xian)(xian)(xian)(xian)軌(gui)、滑(hua)軌(gui)、線(xian)(xian)(xian)(xian)性導(dao)(dao)軌(gui)、線(xian)(xian)(xian)(xian)性滑(hua)軌(gui)，可分(fen)為滾(gun)輪直(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)，圓柱直(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)，滾(gun)珠(zhu)直(zhi)線(xian)(xian)(xian)(xian)導(dao)(dao)軌(gui)三種。

直線(xian)(xian)(xian)(xian)導軌(gui)用于高(gao)精(jing)或高(gao)速直線(xian)(xian)(xian)(xian)往復運(yun)動(dong)場(chang)合，且(qie)可以(yi)承擔一定的(de)扭(niu)矩，可在高(gao)負(fu)載的(de)情況(kuang)下實(shi)現高(gao)精(jing)度的(de)直線(xian)(xian)(xian)(xian)運(yun)動(dong)。在大陸稱直線(xian)(xian)(xian)(xian)導軌(gui)，臺灣一般稱線(xian)(xian)(xian)(xian)性導軌(gui)，線(xian)(xian)(xian)(xian)性滑軌(gui)。

分為方形滾珠直(zhi)線(xian)導軌，雙軸芯滾輪直(zhi)線(xian)導軌，單(dan)軸芯直(zhi)線(xian)導軌。
