(3)傳動效率高,可達0.98,節能效果明顯;
(4)維護保養方便,不需潤滑,維護費用低;
( 5 )速比范圍大,一般可達10,線速度可達50m/s,具有較大的功率傳遞范圍,可達幾瓦到幾百千瓦;
(6)可用于長距離傳動,中心距可達10m以上。
( 7 ) 相對于V型帶傳送,預緊力較小,軸和軸承上所受載荷小;
2.同步帶的安裝
同步帶的安裝方法
①安裝(zhuang)同(tong)步(bu)帶(dai)時,如果兩同(tong)步(bu)帶(dai)輪(lun城叼)的中(zhong)(zhong)心(xin)距(ju)可以(yi)移動,必須(xu)先將同(tong)步(bu)帶(dai)輪(lun)的中(zhong)(zhong)心(xin)距(ju)縮短,裝(zhuang)好同(tong)步(bu)帶(dai)后,再使中(zhong)(zhong)心(xin)距(ju)復(fu)位。若有(you)張(zhang)緊(jin)(jin)輪(lun)時,先把張(zhang)緊(jin)(jin)輪(lun)放松,然后裝(zhuang)上(shang)同(tong)步(bu)帶(dai),再裝(zhuang)上(shang)張(zhang)緊(jin)(jin)輪(lun)。
②往(wang)同(tong)(tong)(tong)步(bu)(bu)(bu)帶(dai)(dai)輪(lun)上裝(zhuang)同(tong)(tong)(tong)步(bu)(bu)(bu)帶(dai)(dai)時(shi)(shi),切記不(bu)要用力(li)過猛,或用螺絲刀硬撬同(tong)(tong)(tong)步(耕蝉bu)(bu)(bu)帶(dai)(dai),以防止同(tong)(tong)(tong)步(bu)(bu)(bu)帶(dai)(dai)中(zhong)的(de)抗拉層產生外觀覺察不(bu)到的(de)折斷現象。設計同(tong)(tong)(tong)步(bu)(bu)(bu)帶(dai)(dai)輪(lun)時(shi)(shi),最好選(xuan)用兩軸(zhou)能互相(xiang)移近的(de)結構(gou)(gou),若結構(g广妥ou)(gou)上不(bu)允許(xu)時(shi)(shi),則最好把(ba)同(tong)(tong)(tong)步(bu)(bu)(bu)帶(dai)(dai)與同(tong)(tong)(tong)步(bu)(bu)(bu)帶(dai)(dai)輪(lun)一起裝(zhuang)到相(xiang)應的(de)軸(zhou)上。
③控制適當的初張緊力(li)。
④同(tong)(tong)(tong)步(bu)帶(dai)(dai)傳動中(zhong),兩帶(dai)(dai)輪(lun)軸(zhou)(zhou)線的平行度要求比較高,否則(ze)同(tong)(tong)(tong)步(bu)帶(dai)(dai)在(zai)工作(zuo)時會產(chan)生跑偏,甚至跳出帶(dai)(dai)輪(lun)。軸(zhou)(zhou)線不平行遠(yuan)將引起壓力不均勻,是同(ton集葫g)(tong)(tong)步(bu)帶(dai)(dai)齒早期磨損。 ⑤支(zhi)撐同(tong)(tong)(tong)步(bu)帶(dai)(dai)輪(lun)的機架,必(bi)須(xu)有足夠的剛(gang)度,否則(ze)同(tong)(tong)(tong)步(bu)帶(dai)(dai)輪(lun)在(zai)運(yun)轉時就會造(zao)成兩軸(zhou)(zhou)線的不平行。
