振(zhen)動平臺振(zhen)源(yuan)軸承進灰怎么辦
混凝土(tu)振動(dong)(dong)平臺振源軸承(cheng)進灰拆裝(zhuang)辦法,而振動(dong)(dong)電(dian)機是振動(dong)(dong)篩最主要(yao)的(de)激振源,其(qi)重要(yao)地(di)位可想而知。混凝土(tu)振動(dong)(dong)平臺振源選用重型軸承(cheng),均可承(cheng)載(zai)一定的(de)軸向負(fu)荷(he),不(bu)(bu)論安裝(zhuang)方向如(ru)何,軸承(cheng)壽命不(bu)(bu)受軸向負(fu)荷(he)力的(de)影響。
1.折卸(xie)軸承(cheng)
 (1)拆下混凝(ning)土(tu)振(zhen)(zhen)動平臺振(zhen)(zhen)源兩端的(de)防(fang)護罩(立式振(zhen)(zhen)動電機無(wu)防(fang)護罩),記錄偏心塊工(gong)作時(shi)的(de)激振(zhen)(zhen)力百分值,以(yi)便在安裝時(shi)恢復原工(gong)作狀態(tai);
(2)將(jiang)兩軸(zhou)端的軸(zhou)用擋圈去掉;
(3)旋松外(wai)偏心塊緊(jin)固螺栓(shuan),卸(xie)下(xia)外(wai)偏心塊,有軸鍵者(zhe)卸(xie)下(xia)軸鍵。旋松內(nei)偏心塊緊(jin)固螺栓(shuan),卸(xie)下(xia)內(nei)偏心塊;
(4)卸下軸(zhou)承座壓緊(jin)螺(luo)栓,用(yong)合適(shi)的螺(luo)栓擰入軸(zhou)承座拆卸螺(luo)孔(kong),將(jiang)軸(zhou)承座從(cong)機殼內(nei)頂出;
(5)將軸承(cheng)壓(ya)(ya)蓋(gai)從(cong)軸承(cheng)座上卸下(xia),把軸承(cheng)從(cong)軸承(cheng)座內壓(ya)(ya)出(chu)或(huo)用合(he)適的螺栓頂出(chu);
 (6)如軸承為內外套(tao)可分離的圓柱(zhu)滾子軸承,應將軸承內套(tao)從軸上取(qu)下,并放入(ru)原配軸承外套(tao)中(zhong);
(7)徹底清洗各(ge)部件油污。
2.安裝(zhuang)軸承(cheng)
混(hun)凝土振動平臺振源(yuan)更換新(xin)軸(zhou)承時,必須使用與(yu)原型號相同的軸(zhou)承。
(1)軸承(cheng)(cheng)(cheng)(cheng)用(yong)煤油洗凈(jing),壓(ya)入軸承(cheng)(cheng)(cheng)(cheng)座,向軸承(cheng)(cheng)(cheng)(cheng)外(wai)圈的(de)滾柱處填充殼牌三號鋰基脂(zhi)至(zhi)三分之二滿,用(yong)凈(jing)手涂抹均(jun)勻,裝上軸承(cheng)(cheng)(cheng)(cheng)壓(ya)蓋,用(yong)加涂螺(luo)栓(shuan)防松膠的(de)緊(jin)固螺(luo)栓(shuan)壓(ya)緊(jin)軸承(cheng)(cheng)(cheng)(cheng)壓(ya)蓋;
(2)軸承(cheng)為內外套(tao)可分離的圓柱滾子(zi)軸承(cheng),應(ying)將(jiang)軸承(cheng)內套(tao)裝于(yu)轉軸上并到位;
(3)將軸(zhou)承座裝于機殼上(shang),如有潤滑脂(zhi)注油孔,必(bi)須對準位置(zhi)。用加涂螺栓防松膠的(de)緊固螺栓壓(ya)緊軸(zhou)承座;
(4)內外偏心(xin)塊裝于轉軸(zhou)(zhou)上并到位,有軸(zhou)(zhou)鍵者(zhe)應將軸(zhou)(zhou)鍵裝入鍵槽內再裝外偏心(xin)塊,將軸(zhou)(zhou)用擋圈裝于轉軸(zhou)(zhou)上;
(5)緊固定偏心塊緊固螺(luo)栓,轉動(dong)可(ke)調偏心塊,使其到達卸下前的(de)角度位置(zhi)并擰緊其緊固螺(luo)栓。以上(shang)組裝完(wan)成后,轉軸應有一定的(de)軸向串(chuan)動(dong);
  (6)上混凝土振動平臺振源兩端的防護罩(zhao),用螺釘緊固(gu)。
