F系列減速電機應用案例FA97齒輪箱
F系列減速電(dian)機(ji)應用案例FA97齒(chi)輪(lun)箱(xiang)。我們平(ping)常使用(yong)的(de)(de)平(ping)行(xing)軸(zhou)減速機，都屬(shu)于(yu)旋轉體，由(you)于(yu)材質不(bu)均勻、毛坯缺(que)陷、加工及裝配中(zhong)產生(sheng)的(de)(de)誤(wu)差、設計時(shi)非(fei)對稱幾何形狀等各種因素，使F系列(lie)減速電機在旋轉過程(cheng)中(zhong)，因存在不(bu)平(ping)衡(heng)而(er)產生(sheng)離心慣性(xing)(xing)力，且隨著旋轉而(er)不(bu)斷周(zhou)期性(xing)(xing)地改變(bian)方向，使旋轉中(zhong)心的(de)(de)位(wei)置無法固(gu)定(ding)不(bu)變(bian)，進而(er)引起平(ping)行(xing)軸(zhou)減速機機械振動、噪音、軸(zhou)承磨損加速、機械壽命縮短，嚴重(zhong)時(shi)會引發(fa)破壞性(xing)(xing)安全(quan)事(shi)故(gu)。
平行軸減速機，F系列減速電機
F系列減(jian)(jian)速電(dian)機(ji)(ji)在(zai)(zai)(zai)更(geng)換低(di)帶軸齒(chi)(chi)輪(lun)后(hou)，齒(chi)(chi)輪(lun)存在(zai)(zai)(zai)明(ming)顯不(bu)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)，為此，必(bi)須對F系列減(jian)(jian)速電(dian)機(ji)(ji)進(jin)行(xing)(xing)(xing)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)試(shi)(shi)驗，使其工(gong)(gong)作在(zai)(zai)(zai)允許的(de)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)精度范圍內。為了不(bu)影(ying)響正常(chang)(chang)的(de)生產(chan)秩序，決定在(zai)(zai)(zai)施(shi)工(gong)(gong)現場(chang)對平(ping)(ping)(ping)(ping)行(xing)(xing)(xing)軸齒(chi)(chi)輪(lun)減(jian)(jian)速機(ji)(ji)的(de)齒(chi)(chi)輪(lun)進(jin)行(xing)(xing)(xing)現場(chang)靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)試(shi)(shi)驗。通常(chang)(chang)情況下，在(zai)(zai)(zai)齒(chi)(chi)輪(lun)發(fa)生靜態不(bu)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)時(shi)，需要將被 測零件安裝在(zai)(zai)(zai)芯軸上，在(zai)(zai)(zai)專用的(de)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)導(dao)軌支架上進(jin)行(xing)(xing)(xing)靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)試(shi)(shi)驗，常(chang)(chang)用的(de)靜平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)支架有圓柱形(xing)(xing)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)架和(he)棱形(xing)(xing)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)架兩(liang)種，結(jie)合(he)生產(chan)中的(de)實際情況，如(ru)果將平(ping)(ping)(ping)(ping)行(xing)(xing)(xing)軸減(jian)(jian)速機(ji)(ji)的(de)齒(chi)(chi)輪(lun)拆卸(xie)下來進(jin)行(xing)(xing)(xing)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)試(shi)(shi)驗，所需時(shi)間長，經濟投入大，于是決定嘗(chang)試(shi)(shi)在(zai)(zai)(zai)現場(chang)利用F系列減(jian)(jian)速電(dian)機(ji)(ji)箱體替代平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)導(dao)軌支架，結(jie)合(he)實際工(gong)(gong)礦條件進(jin)行(xing)(xing)(xing)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)試(shi)(shi)驗，這樣可(ke)又省(sheng)去拆除、裝配(pei)等工(gong)(gong)序，使平(ping)(ping)(ping)(ping)行(xing)(xing)(xing)軸減(jian)(jian)速機(ji)(ji)在(zai)(zai)(zai)工(gong)(gong)作狀態下即可(ke)獲得較高的(de)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)(heng)(heng)精度。
