震(zhen)動電(dian)(dian)(dian)機(ji)由特制電(dian)(dian)(dian)機(ji)外(wai)加激(ji)(ji)振(zhen)重(zhong)塊組成,當(dang)電(dian)(dian)(dian)機(ji)通電(dian)(dian)(dian)旋轉時，激(ji)(ji)振(zhen)塊產生(sheng)激(ji)(ji)振(zhen)力，通過電(dian)(dian)(dian)機(ji)底腳(jiao)傳遞(di)縱橫振(zhen)動機(ji)械。震(zhen)動電(dian)(dian)(dian)機(ji)振(zhen)動頻率范圍大，只有激(ji)(ji)振(zhen)動力與功(gong)率配合(he)得當(dang)才能降(jiang)低機(ji)械噪音。在震(zhen)動電(dian)(dian)(dian)機(ji)使用如此普及的今天，相(xiang)信仍然有很多人(ren)不清(qing)楚震(zhen)動電(dian)(dian)(dian)機(ji)的振(zhen)動方式究竟是怎(zen)樣(yang)的，今天，就為大家科(ke)普一下。
震(zhen)動電(dian)機(ji)(ji)每端(duan)出軸(zhou)均有一個固定(ding)(ding)偏(pian)(pian)心(xin)(xin)(xin)塊(kuai)(kuai)和一個可(ke)調(diao)偏(pian)(pian)心(xin)(xin)(xin)塊(kuai)(kuai),調(diao)節可(ke)調(diao)偏(pian)(pian)心(xin)(xin)(xin)塊(kuai)(kuai)和固定(ding)(ding)偏(pian)(pian)心(xin)(xin)(xin)塊(kuai)(kuai)之(zhi)間的(de)(de)夾角(jiao)(jiao)可(ke)改(gai)變激(ji)振力(li)(li)的(de)(de)大小。出廠時(shi)可(ke)調(diao)偏(pian)(pian)心(xin)(xin)(xin)塊(kuai)(kuai)和固定(ding)(ding)偏(pian)(pian)心(xin)(xin)(xin)塊(kuai)(kuai)之(zhi)間的(de)(de)夾角(jiao)(jiao)為0度(du),這時(shi)的(de)(de)激(ji)振力(li)(li)為震(zhen)動電(dian)機(ji)(ji)的(de)(de)額定(ding)(ding)激(ji)振力(li)(li)F,不同(tong)(tong)夾角(jiao)(jiao)時(shi)的(de)(de)激(ji)振力(li)(li): 要特別注意,調(diao)整(zheng)激(ji)振力(li)(li)時(shi),要將震(zhen)動電(dian)機(ji)(ji)兩端(duan)出軸(zhou)上的(de)(de)可(ke)調(diao)偏(pian)(pian)心(xin)(xin)(xin)塊(kuai)(kuai)向同(tong)(tong)一個方向調(diao)整(zheng)為相同(tong)(tong)的(de)(de)角(jiao)(jiao)度(du)。
激振力(li)的調整步驟:
⒈ 拆除防護罩。
  ⒉ 旋(xuan)松外(wai)側(ce)偏心(xin)塊加緊螺栓。
⒊ 兩側偏(pian)心塊應同方向轉動,使軸上刻線對準偏(pian)心塊上激(ji)振(zhen)力示值(zhi)線至需(xu)要的激(ji)振(zhen)力值(zhi)處,并檢查兩端是(shi)否為相同的角度(du)。
一種是叫(jiao)做(zuo)圓(yuan)或(huo)橢圓(yuan)振(zhen)(zhen)動(dong)(dong)(dong)。振(zhen)(zhen)動(dong)(dong)(dong)體的(de)(de)(de)(de)振(zhen)(zhen)動(dong)(dong)(dong)軌(gui)跡在水平(ping)面上(shang)的(de)(de)(de)(de)投(tou)影(ying)是一條直線(xian)，而在垂直面上(shang)的(de)(de)(de)(de)投(tou)影(ying)為(wei)一圓(yuan)或(huo)橢圓(yuan)者，其振(zhen)(zhen)動(dong)(dong)(dong)形式稱為(wei) 圓(yuan)或(huo)橢圓(yuan)型振(zhen)(zhen)動(dong)(dong)(dong)。圓(yuan)形或(huo)橢圓(yuan)形振(zhen)(zhen)動(dong)(dong)(dong)發生在與震(zhen)動(dong)(dong)(dong)電(dian)機(ji)(ji)轉(zhuan)軸相垂直的(de)(de)(de)(de)平(ping)面上(shang)，其形式則看震(zhen)動(dong)(dong)(dong)電(dian)機(ji)(ji)與整機(ji)(ji)的(de)(de)(de)(de)相對位置而定(ding)。通(tong)常將一臺(tai)震(zhen)動(dong)(dong)(dong)電(dian)機(ji)(ji)安裝在振(zhen)(zhen)動(dong)(dong)(dong)機(ji)(ji)械機(ji)(ji)體上(shang)，既可產生這種運動(dong)(dong)(dong)。機(ji)(ji)體強度大(da)，激振(zhen)(zhen)力與出力配合(he)適(shi)當，激振(zhen)(zhen)力大(da)，可按照不同的(de)(de)(de)(de)用(yong)途(tu)選擇振(zhen)(zhen)動(dong)(dong)(dong)頻率和振(zhen)(zhen)幅，能滿足(zu)各類振(zhen)(zhen)動(dong)(dong)(dong)機(ji)(ji)械的(de)(de)(de)(de)工作需要。
二種(zhong)是直線(xian)振(zhen)動(dong)(dong)(dong)(dong)(dong)。振(zhen)動(dong)(dong)(dong)(dong)(dong)體(ti)的(de)(de)(de)振(zhen)動(dong)(dong)(dong)(dong)(dong)軌跡在(zai)水平(ping)面及垂(chui)直面上(shang)的(de)(de)(de)投影都是直線(xian)者，其振(zhen)動(dong)(dong)(dong)(dong)(dong)形(xing)式稱為直線(xian)型振(zhen)動(dong)(dong)(dong)(dong)(dong)。將兩(liang)臺(tai)相(xiang)同型號的(de)(de)(de)震(zhen)動(dong)(dong)(dong)(dong)(dong)電機(ji)(ji)(ji)安裝在(zai)振(zhen)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)械機(ji)(ji)(ji)體(ti)上(shang)，使兩(liang)個轉軸處于(yu)互(hu)相(xiang)平(ping)行的(de)(de)(de)位置，運行時電機(ji)(ji)(ji)轉向相(xiang)反，則兩(liang)臺(tai)電機(ji)(ji)(ji)運轉必然同步，機(ji)(ji)(ji)體(ti)產(chan)生直線(xian)形(xing)振(zhen)動(dong)(dong)(dong)(dong)(dong)。兩(liang)軸端(duan)各一塊(kuai)，上(shang)軸端(duan)為固(gu)定偏心(xin)塊(kuai)，下軸端(duan)為可(ke)調偏心(xin)塊(kuai)。在(zai)上(shang)下偏心(xin)塊(kuai)的(de)(de)(de)外側各裝有一組附加(jia)塊(kuai)，通過調節附加(jia)塊(kuai)的(de)(de)(de)數量，可(ke)以分級調節震(zhen)動(dong)(dong)(dong)(dong)(dong)電機(ji)(ji)(ji)的(de)(de)(de)激振(zhen)力。
三(san)種(zhong)叫做旋(xuan)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)。當(dang)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)體的(de)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)軌跡(ji)(ji)在(zai)(zai)水平面(mian)(mian)上(shang)的(de)投影(ying)(ying)是一圓或橢圓者(zhe)(zhe)，其振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)稱為(wei)(wei)旋(xuan)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)。因為(wei)(wei)震(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)電機是強(qiang)阻(zu)型(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)而不是共振(zhen)(zhen)，所以(yi)有穩定的(de)振(zhen)(zhen)幅。旋(xuan)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)又可分為(wei)(wei)平旋(xuan)型(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)、渦旋(xuan)型(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)、復旋(xuan)型(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)三(san)種(zhong)形式(shi)。當(dang)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)體的(de)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)軌跡(ji)(ji)在(zai)(zai)垂直(zhi)面(mian)(mian)上(shang)的(de)投影(ying)(ying)為(wei)(wei)一水平直(zhi)線(xian)者(zhe)(zhe)，其振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)稱為(wei)(wei)平旋(xuan)型(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong);當(dang)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)體的(de)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)軌跡(ji)(ji)在(zai)(zai)垂直(zhi)面(mian)(mian)上(shang)的(de)投影(ying)(ying)為(wei)(wei)一斜直(zhi)線(xian)者(zhe)(zhe)，其振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)稱為(wei)(wei)渦旋(xuan)型(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong);當(dang)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)體的(de)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)軌跡(ji)(ji)在(zai)(zai)垂直(zhi)面(mian)(mian)上(shang)的(de)投影(ying)(ying)為(wei)(wei)一圓或橢圓者(zhe)(zhe)，其振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)形式(shi)稱為(wei)(wei)復旋(xuan)型(xing)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)。震(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)電機的(de)激振(zhen)(zhen)力可以(yi)無級調(diao)節，使用方便。
