同(tong)步(bu)帶(dai)(dai)(dai)(dai)對于(yu)大多數同(tong)行來(lai)說(shuo)，應該司(si)空見慣了。同(tong)步(bu)帶(dai)(dai)(dai)(dai)傳(chuan)動(dong)(dong)(dong)(dong)通過傳(chuan)動(dong)(dong)(dong)(dong)帶(dai)(dai)(dai)(dai)內(nei)表面上(shang)(shang)等距(ju)(ju)分布的橫向齒(chi)和(he)帶(dai)(dai)(dai)(dai)輪(lun)上(shang)(shang)的相應齒(chi)槽的嚙合來(lai)傳(chuan)遞運(yun)動(dong)(dong)(dong)(dong)。與摩擦型(xing)(xing)帶(dai)(dai)(dai)(dai)傳(chuan)動(dong)(dong)(dong)(dong)比(bi)較(jiao)，同(tong)步(bu)帶(dai)(dai)(dai)(dai)傳(chuan)動(dong)(dong)(dong)(dong)的帶(dai)(dai)(dai)(dai)輪(lun)和(he)傳(chuan)動(dong)(dong)(dong)(dong)帶(dai)(dai)(dai)(dai)之間沒有相對滑動(dong)(dong)(dong)(dong)，能(neng)夠保證嚴格的傳(chuan)動(dong)(dong)(dong)(dong)比(bi)。但(dan)同(tong)步(bu)帶(dai)(dai)(dai)(dai)傳(chuan)動(dong)(dong)(dong)(dong)對中心距(ju)(ju)及其尺寸穩(wen)定性要求(qiu)較(jiao)高。在(zai)(zai)(zai)這(zhe)(zhe)組機(ji)(ji)構(gou)中，同(tong)步(bu)帶(dai)(dai)(dai)(dai)通過同(tong)步(bu)帶(dai)(dai)(dai)(dai)齒(chi)板(ban)、同(tong)步(bu)帶(dai)(dai)(dai)(dai)壓板(ban)的雙面壓緊帶(dai)(dai)(dai)(dai)動(dong)(dong)(dong)(dong)直線模(mo)組的運(yun)動(dong)(dong)(dong)(dong)。顯而易見，這(zhe)(zhe)種傳(chuan)動(dong)(dong)(dong)(dong)機(ji)(ji)構(gou)比(bi)較(jiao)實惠，而且(qie)同(tong)步(bu)帶(dai)(dai)(dai)(dai)傳(chuan)動(dong)(dong)(dong)(dong)具有準確的傳(chuan)動(dong)(dong)(dong)(dong)比(bi)，傳(chuan)動(dong)(dong)(dong)(dong)效率高，且(qie)傳(chuan)動(dong)(dong)(dong)(dong)平穩(wen)，具有緩沖、減振(zhen)作用(yong)。但(dan)是缺點是占用(yong)空間比(bi)較(jiao)大，對于(yu)緊湊型(xing)(xing)的機(ji)(ji)構(gou)來(lai)說(shuo)可能(neng)不(bu)(bu)太(tai)適用(yong)，而且(qie)傳(chuan)動(dong)(dong)(dong)(dong)負載也不(bu)(bu)是很(hen)大。同(tong)步(bu)帶(dai)(dai)(dai)(dai)齒(chi)板(ban)和(he)壓板(ban)在(zai)(zai)(zai)市面上(shang)(shang)也能(neng)采購到，它上(shang)(shang)面的齒(chi)形是以同(tong)步(bu)齒(chi)形帶(dai)(dai)(dai)(dai)為標準加(jia)工(gong)而成的，材質(zhi)一般為45#發(fa)黑或者鋁合金(jin)陽極氧化。這(zhe)(zhe)種移料機(ji)(ji)構(gou)有一點需要注意(yi)，請勿在(zai)(zai)(zai)同(tong)步(bu)帶(dai)(dai)(dai)(dai)上(shang)(shang)開安裝孔，會大大影(ying)響模(mo)型(xing)(xing)的使用(yong)和(he)壽命。接下(xia)來(lai)還是看一下(xia)這(zhe)(zhe)組機(ji)(ji)構(gou)的設計細節，
首(shou)先是直(zhi)線(xian)(xian)(xian)導軌，在設(she)計過程(cheng)中，每次用到直(zhi)線(xian)(xian)(xian)導軌需(xu)要考(kao)慮的細(xi)節就是直(zhi)線(xian)(xian)(xian)導軌和(he)滑塊的安裝基(ji)準，以及運動中的限位，包(bao)括(kuo)硬限位和(he)軟限位。
同(tong)(tong)樣，在(zai)(zai)使用(yong)同(tong)(tong)步(bu)(bu)(bu)(bu)帶(dai)傳動(dong)時，也(ye)應(ying)該考慮同(tong)(tong)步(bu)(bu)(bu)(bu)帶(dai)的漲緊(jin)問題。在(zai)(zai)本機構中兩處(chu)(chu)使用(yong)了同(tong)(tong)步(bu)(bu)(bu)(bu)帶(dai)。在(zai)(zai)第一處(chu)(chu)，電機傳動(dong)使用(yong)了同(tong)(tong)步(bu)(bu)(bu)(bu)帶(dai)，通過螺釘調節(jie)(jie)電機的安裝座整體來調節(jie)(jie)同(tong)(tong)步(bu)(bu)(bu)(bu)帶(dai)的漲緊(jin)。此處(chu)(chu)由于空間有限(xian)，電機安裝在(zai)(zai)底板底部(bu)，所以對(dui)調節(jie)(jie)漲緊(jin)可能會(hui)不方(fang)便。第二處(chu)(chu)調節(jie)(jie)漲緊(jin)就是普通的通過調節(jie)(jie)同(tong)(tong)步(bu)(bu)(bu)(bu)輪(lun)安裝座來調節(jie)(jie)漲緊(jin)程度。
