隨著不(bu)同(tong)國(guo)家不(bu)同(tong)機(ji)(ji)型(xing)顎式(shi)(shi)(shi)破碎(sui)(sui)機(ji)(ji)產(chan)品(pin)的(de)(de)引進(jin)，對國(guo)內顎式(shi)(shi)(shi)破碎(sui)(sui)機(ji)(ji)的(de)(de)生(sheng)產(chan)廠(chang)商改進(jin)產(chan)品(pin)結構(gou)、提高產(chan)品(pin)技術水平、推出新機(ji)(ji)型(xing)也起到了促進(jin)和(he)推動(dong)作用(yong)。以下(xia)本(ben)文(wen)就顎式(shi)(shi)(shi)破碎(sui)(sui)機(ji)(ji)電動(dong)機(ji)(ji)安裝方式(shi)(shi)(shi)的(de)(de)不(bu)同(tong)結構(gou)進(jin)行分析，并(bing)進(jin)行優劣比較(jiao)，以期對國(guo)內顎式(shi)(shi)(shi)破碎(sui)(sui)機(ji)(ji)的(de)(de)改進(jin)和(he)創新起到拋磚引玉(yu)的(de)(de)作用(yong)。

不同的電動機安裝方式

顎式破碎(sui)機的動(dong)(dong)力來源一般(ban)是電動(dong)(dong)機，電動(dong)(dong)機通過帶輪和(he)三角(jiao)帶帶動(dong)(dong)偏(pian)心軸(zhou)轉動(dong)(dong)，從而帶動(dong)(dong)安裝在(zai)偏(pian)心軸(zhou)上(shang)動(dong)(dong)顎做周期性往復(fu)運動(dong)(dong)。

傳(chuan)統的(de)顎式破(po)碎(sui)機的(de)電動(dong)機都(dou)是(shi)安裝在滑軌結構的(de)電動(dong)機機座上(shang)(shang)，機座再安裝在混凝(ning)土或鋼結構的(de)基礎上(shang)(shang)。這種結構是(shi)通(tong)過(guo)在滑軌上(shang)(shang)移動(dong)電動(dong)機張緊(jin)三(san)角傳(chuan)動(dong)帶。電動(dong)機離破(po)碎(sui)機機體較遠(yuan)，傳(chuan)動(dong)三(san)角帶較長，需(xu)要在現場安裝調試，而且電動(dong)機需(xu)要占(zhan)用(yong)較大的(de)安裝空間(jian)。

一體化電動機安裝方式的優點

通(tong)過以上對顎(e)破電動(dong)(dong)機(ji)不同安(an)裝(zhuang)(zhuang)方式(shi)的分(fen)析(xi)，我們可(ke)以得出新型的顎(e)破電動(dong)(dong)機(ji)的一體化安(an)裝(zhuang)(zhuang)方式(shi)與電動(dong)(dong)機(ji)分(fen)體安(an)裝(zhuang)(zhuang)方式(shi)相(xiang)比具(ju)有以下(xia)優(you)點。

（1）電動(dong)機不(bu)需要在用(yong)戶使用(yong)現(xian)場安裝，因此破碎機安裝更簡(jian)單，并減(jian)少了設備(bei)基礎施工成本。

（2）減小了傳動(dong)三(san)角帶長(chang)度，三(san)角帶更(geng)易(yi)張(zhang)緊；而且(qie)電動(dong)機膠帶輪(lun)與(yu)主軸膠帶輪(lun)都在(zai)破碎機機體上，不存在(zai)相對運動(dong)，因此(ci)，傳動(dong)三(san)角帶的使用壽命更(geng)長(chang)。

（3）破碎機能(neng)夠使用(yong)標準的膠帶輪護罩(zhao)和(he)飛輪護罩(zhao)，從而不(bu)必(bi)要(yao)對(dui)防護罩(zhao)在現場(chang)進行施工，避(bi)免了用(yong)戶使用(yong)現場(chang)由于忽(hu)視安(an)(an)全工作而不(bu)安(an)(an)裝防護罩(zhao)的問題(ti)，設備使用(yong)更安(an)(an)全。

一體化電動機安裝要注意的問題

采用一體化電(dian)動機安裝方式要注意以下三方面問題：

（1）如(ru)果是對傳(chuan)統破碎機進(jin)行(xing)一(yi)體(ti)化電動機安裝改造(zao)，那么由(you)于電機膠帶(dai)輪與大膠帶(dai)輪中心(xin)距(ju)縮短，需要重(zhong)新對三角帶(dai)傳(chuan)動進(jin)行(xing)計算，確(que)定三角帶(dai)的數量和長度。

（2）電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)與顎破一(yi)(yi)體化安(an)裝(zhuang)(zhuang)后，顎破的(de)(de)整機(ji)(ji)(ji)平(ping)衡性會(hui)產生變化，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)越(yue)重(zhong)(zhong)對(dui)整機(ji)(ji)(ji)平(ping)衡性影(ying)響越(yue)大。對(dui)于Y2系列電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)來說，在相同電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)功率的(de)(de)情(qing)況(kuang)下，4級(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)輕(qing)(qing)于6級(ji)和8級(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)，有的(de)(de)型號(hao)重(zhong)(zhong)量(liang)還(huan)相差很大，比如，90kW的(de)(de)4級(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)Y2-280M-4（重(zhong)(zhong)量(liang)667kg）比6級(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)Y2-315M-6（重(zhong)(zhong)量(liang)1080kg）輕(qing)(qing)413kg。而且(qie)，4級(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)體積也要小(xiao)于6級(ji)或8級(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)。因(yin)此，對(dui)于顎破一(yi)(yi)體化電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)安(an)裝(zhuang)(zhuang)結(jie)構來說，更宜(yi)采用4級(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)。但(dan)是(shi)，如果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)膠帶輪(lun)的(de)(de)三角(jiao)(jiao)帶包角(jiao)(jiao)過小(xiao)，導致(zhi)三角(jiao)(jiao)帶數量(liang)太(tai)多不好(hao)布置，也可采用6級(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)。

（3）對于傳統的顎破電機(ji)(ji)分(fen)體安(an)裝結構來說，如(ru)果(guo)改為一體化(hua)的電機(ji)(ji)安(an)裝，破碎(sui)機(ji)(ji)的平(ping)(ping)(ping)衡(heng)配重要進行(xing)重新(xin)調(diao)整。這(zhe)是(shi)因為電動(dong)機(ji)(ji)安(an)裝在破碎(sui)機(ji)(ji)上之(zhi)后，整個(ge)設備的平(ping)(ping)(ping)衡(heng)性(xing)就發(fa)生(sheng)了改變，如(ru)果(guo)不對平(ping)(ping)(ping)衡(heng)配重進行(xing)重新(xin)調(diao)整，運轉時會產(chan)生(sheng)較大的振動(dong)，影響設備的正常使用(yong)和壽命(ming)。

總之，顎式(shi)(shi)破碎機(ji)一體化電動(dong)(dong)機(ji)安裝(zhuang)(zhuang)具有設備安裝(zhuang)(zhuang)簡便、基礎施工成本低(di)、傳(chuan)動(dong)(dong)帶更短、使(shi)(shi)(shi)用壽命更長以(yi)及(ji)設備使(shi)(shi)(shi)用安全性好的優點，使(shi)(shi)(shi)設備的操作(zuo)使(shi)(shi)(shi)用更具人(ren)性化。因此，筆者(zhe)認為應(ying)該推廣(guang)采用一體化電動(dong)(dong)機(ji)安裝(zhuang)(zhuang)方(fang)式(shi)(shi)，并通(tong)過設備改造，逐步取代(dai)傳(chuan)統的電動(dong)(dong)機(ji)分體安裝(zhuang)(zhuang)方(fang)式(shi)(shi)，使(shi)(shi)(shi)我國的顎式(shi)(shi)破碎機(ji)產品水平得以(yi)提高，并逐漸達到世界先進水平。
