    減速機技術(shù)資料:


    在選擇減速機的型號時應(yīng)注意的幾個事項:盡量選用接近理想減速比:減速比=伺服馬達轉(zhuǎn)速/減速機出力軸轉(zhuǎn)速扭力計算:對減速機的壽命而言,扭力計算非常重要,并且要注意加速度的最大轉(zhuǎn)矩值(TP),是否超過減速機之最大負載扭力。
    適用功率通常為市面上的伺服機種的適用功率,減速機的適用性很高,工作系數(shù)都能維持在1.2以上,但在選用上也可以以自己的需要來決定,要點有二:A.選用伺服電機的出力軸徑不能大于表格上最大使用軸徑;B.若經(jīng)扭力計算工作,轉(zhuǎn)速可以滿足平常運轉(zhuǎn),但在伺服全額輸出時,有不足現(xiàn)象時,我們可以在電機側(cè)之驅(qū)動器,做限流控制,或在機械軸上做扭力保護,這是很必要的。
    通用減速機的選型包括提出原始條件、選擇類型、確定規(guī)格等步驟。
    相比之下,類型選擇比較簡單,而準確提供減速器的工況條件,掌握減速器的設(shè)計、制造和使用特點是通用減速器正確合理選擇規(guī)格的關(guān)鍵。
    規(guī)格選擇要滿足強度、熱平衡、軸伸部位承受徑向載荷等條件。
    1.按機械功率或轉(zhuǎn)矩選擇規(guī)格(強度校核)通用減速器和專用減速器設(shè)計選型方法的最大不同在于,前者適用于各個行業(yè),但減速只能按一種特定的工況條件設(shè)計,故選用時用戶需根據(jù)各自的要求考慮不同的修正系數(shù),工廠應(yīng)該按實際選用的電動機功率(不是減速器的額定功率)打銘牌;后者按用戶的專用條件設(shè)計,該考慮的系數(shù),設(shè)計時一般已作考慮,選用時只要滿足使用功率小于等于減速器的額定功率即可,方法相對簡單。
    通用減速器的額定功率一般是按使用(工況)系數(shù)KA=1(電動機或汽輪機為原動機,工作機載荷平穩(wěn),每天工作3~10h,每小時啟動次數(shù)≤5次,允許啟動轉(zhuǎn)矩為工作轉(zhuǎn)矩的2倍),接觸強度安全系數(shù)SH≈1、單對齒輪的失效概率≈1%,等條件計算確定的。
    所選減速器的額定功率應(yīng)滿足:PC=P2KAKSKR≤PN式中PC———計算功率(KW);PN———減速器的額定功率( KW);P2———工作機功率(KW);KA———使用系數(shù),考慮使用工況的影響;KS———啟動系數(shù),考慮啟動次數(shù)的影響;KR———可靠度系數(shù),考慮不同可靠度要求。
    目前世界各國所用的使用系數(shù)基本相同。雖然許多樣本上沒有反映出KS\ KR兩個系數(shù),但由于知己(對自身的工況要求清楚)、知彼(對減速器的性能特點清楚),國外選型時一般均留有較大的富裕量,相當于已考慮了KR\ KS的影響。
    由于使用場合不同、重要程度不同、損壞后對人身安全及生產(chǎn)造成的損失大小不同、維修難易不同,因而對減速器的可靠度的要求也不相同。系數(shù)KR就是實際需要的可靠度對原設(shè)計的可靠度進行修正。它符合ISO6336、GB3480和AGMA2001—B88(美國齒輪制造者協(xié)會標準)對齒輪強度計算方法的規(guī)定。目前,國內(nèi)一些用戶對減速器的可靠度尚提不出具體量的要求,可按一般專用減速器的設(shè)計規(guī)定(SH≥1.25,失效概率≤1/1000),較重要場合取KR=1.25=1.56左右。
    2、熱平衡校核通用減速器的許用熱功率值是在特定工況條件下(一般環(huán)境溫度20℃,每小時100%,連續(xù)運轉(zhuǎn)、功率利用率100%),按潤滑油允許的最高平衡溫度(一般為85℃)確定的。條件不同時按相應(yīng)系數(shù)(有時綜合成一個系數(shù))進行修正。
    所選減速器應(yīng)滿足:PCt=P2KTKWKP≤Pt式中 PCt———計算熱功率(KW);母線加工機KT———環(huán)境溫度系數(shù);KW———運轉(zhuǎn)周期系數(shù);KP———功率利用率系數(shù);Pt———減速器許用熱功率(KW)。
    3.校核軸伸部位承受的徑向載荷通用減速器常常須對輸入軸、輸出軸軸伸中間部位允許承受的最大徑向載荷給予限制,應(yīng)予校核,超過時應(yīng)向制造廠提出加粗軸徑和加大軸承等要求。
