滑環整體依靠彈力(li)搭(da)接原理(li)、滾(gun)動(dong)搭(da)接原理(li)、或(huo)密(mi)(mi)封原理(li),以(yi)及(ji)巧妙的(de)(de)(de)運(yun)動(dong)結構(gou)(gou)與密(mi)(mi)封結構(gou)(gou)設(she)(she)計(ji)、精密(mi)(mi)的(de)(de)(de)零件制作配(pei)合、合理(li)的(de)(de)(de)選材等(deng),構(gou)(gou)成穩(wen)定(ding)可(ke)靠的(de)(de)(de)旋(xuan)轉(zhuan)(zhuan)連通系統。只(zhi)要(yao)將滑環附著于無限(xian)旋(xuan)轉(zhuan)(zhuan)的(de)(de)(de)設(she)(she)備上,就可(ke)以(yi)給旋(xuan)轉(zhuan)(zhuan)體提供動(dong)力(li)能源(yuan),使旋(xuan)轉(zhuan)(zhuan)體在無限(xian)旋(xuan)轉(zhuan)(zhuan)運(yun)動(dong)的(de)(de)(de)同時(shi),還能進行其它運(yun)動(dong)、或(huo)檢(jian)測旋(xuan)轉(zhuan)(zhuan)狀(zhuang)態(tai)下的(de)(de)(de)工作狀(zhuang)況。
近代,在(zai)工(gong)業設(she)備(bei)的(de)(de)高端領(ling)域(yu)中,多(duo)有諸如公(gong)轉、自轉等多(duo)元相對(dui)運(yun)動的(de)(de)要求。即機械設(she)備(bei)360°連續旋(xuan)轉運(yun)動的(de)(de)同時,旋(xuan)轉體上還需(xu)要多(duo)元運(yun)動。有運(yun)動,就需(xu)要能(neng)(neng)源(yuan)(yuan),如電(dian)(dian)能(neng)(neng)源(yuan)(yuan)、流體壓(ya)力能(neng)(neng)源(yuan)(yuan)等。有時,也需(xu)要控制(zhi)信(xin)號源(yuan)(yuan),如光(guang)纖(xian)信(xin)號、高頻信(xin)號等。任何相對(dui)連續旋(xuan)轉360°的(de)(de)電(dian)(dian)氣部件之間(jian)需(xu)要傳輸功能(neng)(neng)電(dian)(dian)源(yuan)(yuan)、弱電(dian)(dian)信(xin)號、光(guang)信(xin)號、氣壓(ya)、水壓(ya)、油壓(ya)等不同能(neng)(neng)源(yuan)(yuan)介質,以確保電(dian)(dian)器在(zai)旋(xuan)轉運(yun)動時還能(neng)(neng)自由運(yun)動的(de)(de)機電(dian)(dian)設(she)備(bei),都(dou)必須(xu)使用旋(xuan)轉連通(tong)裝置。
