數控切割(ge)(ge)機的運作(zuo)，牢固(gu)性是至(zhi)關重要的基本，這一方面取決于數控切割(ge)(ge)機把持(chi)體(ti)系等(deng)軟件的牢固(gu)性，另(ling)一方面則須要相干機械部件的硬(ying)件支撐，如驅動體(ti)系的牢固(gu)性。以目前市(shi)道上(shang)數控切割(ge)(ge)機常用的驅動把持(chi)體(ti)系來看，其傳動組成重要分(fen)為兩大類(lei)，為了便利(li)用戶辨別跟理(li)解，公司將重要就這兩類(lei)傳動體(ti)系予以簡單介紹及說明。

1、同步齒形帶

同步齒(chi)形(xing)帶(dai)(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)是一種新型(xing)的(de)(de)(de)(de)(de)帶(dai)(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)。它利(li)用(yong)(yong)齒(chi)形(xing)帶(dai)(dai)的(de)(de)(de)(de)(de)齒(chi)形(xing)與(yu)帶(dai)(dai)輪的(de)(de)(de)(de)(de)輪齒(chi)順次(ci)齒(chi)合傳(chuan)(chuan)遞(di)活動(dong)(dong)(dong)(dong)跟(gen)能源，因此(ci)兼(jian)有帶(dai)(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)及鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)的(de)(de)(de)(de)(de)優(you)點(dian)，且無滑動(dong)(dong)(dong)(dong)，均勻(yun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)比較正確，傳(chuan)(chuan)動(dong)(dong)(dong)(dong)精度高(gao)。齒(chi)形(xing)帶(dai)(dai)無需特別張緊，故作用(yong)(yong)在(zai)軸(zhou)跟(gen)軸(zhou)承上的(de)(de)(de)(de)(de)載荷小，傳(chuan)(chuan)動(dong)(dong)(dong)(dong)效力也高(gao)，現(xian)已在(zai)數控機床上普遍利(li)用(yong)(yong)。齒(chi)形(xing)帶(dai)(dai)的(de)(de)(de)(de)(de)強度高(gao)、厚度小、分(fen)量輕，可用(yong)(yong)于(yu)高(gao)速(su)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)。同步齒(chi)形(xing)帶(dai)(dai)的(de)(de)(de)(de)(de)重(zhong)要數與(yu)規(gui)格(ge)如下

1)齒(chi)距——齒(chi)距為(wei)相鄰兩齒(chi)在節線(xian)上的間隔。因為(wei)強(qiang)力層在工作時度不(bu)變，所以強(qiang)力層的中心線(xian)被劃定為(wei)齒(chi)形帶的節線(xian)。

2)模數(shu)——模是齒形帶尺寸盤算的一(yi)個重要(yao)依據。

3)其它參(can)數——齒形帶的其它參(can)數跟尺寸(cun)與漸開線齒條(tiao)基本雷同。

2、齒(chi)輪傳(chuan)動(dong)裝置

與采取(qu)同步齒形帶比(bi)較，在數控(kong)機床進給(gei)傳(chuan)動(dong)(dong)(dong)(dong)鏈中采取(qu)齒輪減(jian)速(su)裝置(zhi)，更(geng)易產生(sheng)低(di)頻振蕩(dang)，因(yin)此減(jian)速(su)機構中常配置(zhi)阻(zu)尼器來改良動(dong)(dong)(dong)(dong)態機能。齒輪傳(chuan)動(dong)(dong)(dong)(dong)是(shi)(shi)利用十分普遍的(de)一(yi)種機械傳(chuan)動(dong)(dong)(dong)(dong)，各種機床的(de)傳(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)中多少(shao)乎都(dou)有(you)(you)齒輪傳(chuan)動(dong)(dong)(dong)(dong)。在數控(kong)機床伺(si)服進給(gei)體系中采取(qu)齒輪傳(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)的(de)目(mu)標有(you)(you)兩個。一(yi)是(shi)(shi)將高轉(zhuan)速(su)的(de)轉(zhuan)矩(ju)的(de)伺(si)服電機的(de)輸(shu)出轉(zhuan)變(bian)為(wei)低(di)轉(zhuan)速(su)大(da)轉(zhuan)矩(ju)的(de)履行件的(de)輸(shu)入(ru)；另一(yi)是(shi)(shi)使滾珠絲杠(gang)跟工作臺的(de)轉(zhuan)動(dong)(dong)(dong)(dong)慣(guan)量在體系中專(zhuan)有(you)(you)較小的(de)比(bi)重(zhong)。

為了(le)盡量減(jian)小齒(chi)(chi)(chi)側縫隙對數控(kong)機床加工精度的影(ying)響，經(jing)常在結構上采取(qu)辦(ban)法，以減(jian)小或(huo)消(xiao)除齒(chi)(chi)(chi)輪副(fu)的空程(cheng)誤差。如采取(qu)雙片齒(chi)(chi)(chi)輪錯齒(chi)(chi)(chi)法、利用偏心套(tao)調(diao)劑(ji)齒(chi)(chi)(chi)輪副(fu)中心距或(huo)采取(qu)軸向墊片調(diao)劑(ji)法消(xiao)除齒(chi)(chi)(chi)輪側隙，讓機械運行跟(gen)機器切割都能達(da)到(dao)更好的后果(guo)！
