圓弧圓柱蝸桿減速器與普通圓柱蝸桿減速器相比較,具有結(jié)構(gòu)緊湊、體積小、質(zhì)量輕的優(yōu)點(diǎn)。蝸桿齒廓為ZC1的蝸桿減速器有四種型式:基本型圓弧圓柱蝸桿減速器、軸裝式圓弧圓柱蝸桿減速器、立式圓弧圓柱蝸桿減速器、ZC1型雙級蝸桿及齒輪-蝸桿減速器。
CW型圓弧圓柱蝸桿減速器(JB/T 7935-1999)采用滲碳、淬火及磨削的ZC1蝸桿傳動,承載能力大、傳動效率較高、壽命長。適用于冶金、礦山、起重、運(yùn)輸、化工、建筑、建材、能源、輕工等行業(yè),是應(yīng)用范圍廣泛的通用減速器。
工作條件:蝸桿轉(zhuǎn)速不超過1500r/min;工作環(huán)境溫度為-40~40℃,當(dāng)工作環(huán)境溫度低于0℃時,啟動前潤滑油必須加熱到0℃以上,或采用低凝固點(diǎn)的潤滑油,當(dāng)工作溫度高于40℃時,必須采取冷卻措施;減速器可正反向運(yùn)轉(zhuǎn)。

1.輸入功率和輸出轉(zhuǎn)矩
CW型蝸桿減速器額定輸入功率P1N(KW)各額定輸出轉(zhuǎn)矩了T2(N·n)見表3.4。表3.4中的額定輸入功率P1及額定輸出轉(zhuǎn)矩T2適用于如下工作條件:減速器工作載荷 平穩(wěn),無沖擊,每日工作8h,每小時啟動10次,啟動轉(zhuǎn)矩不超過額定轉(zhuǎn)矩的2.5倍,小時負(fù)荷率JC=100%,環(huán)境溫度為20℃。當(dāng)上述條件不能滿足時,應(yīng)依據(jù)表3.6~表3.9進(jìn)行修正。
2. 傳動效率
CW型蝸桿減速器的傳動效率見表3.5。

表3.6中的FR是根據(jù)外力作用于輸出軸軸端的中點(diǎn)確定的,見圖3.2。
CW系列圓弧圓柱蝸桿減速器承載能力傳動效率(JB/T 7935-1999)
當(dāng)外力作用點(diǎn)偏離中點(diǎn)△L時,其許用徑向載荷應(yīng)由式(3.1)確定:
式中的正負(fù)號分別對應(yīng)于外力作用點(diǎn)由軸端中點(diǎn)向外側(cè)及內(nèi)側(cè)偏移的情形。

2.選用方法
(1)選用減速器應(yīng)已知原動機(jī)、工作機(jī)類型能參數(shù)、載荷性質(zhì)及大小、每日運(yùn)行時間、每小時啟動次數(shù)、環(huán)境溫度和軸端載荷等。
(2)已知條件與表3.4規(guī)定的工作條件相同時,可直接由表3.4選取所需減速器的規(guī)格。
(3)已知條件與表3.4規(guī)定的工作條件不同時,應(yīng)由式(3.2)~式(3.5)進(jìn)行修正計算,再由計算結(jié)果的較大值由表3.4選取承載能力相符或偏大的減速器。
或 P1J=P1Bf1f2 (3.2)
P1R= P1Bf3f4 (3.3)
T2J=T2Bf1f2 (3.4)
T2R=T2Bf3f4 (3.5)
式中Pu——減速器計算輸入機(jī)械功率,kW;
P1R——減速器計算輸入熱功率,kW;
T2J——減速器計算輸出機(jī)械轉(zhuǎn)矩,N·m;
T2R——減速器計算輸出熱功率,N·m;
P1B——減速器實際輸入功率,kW;
T2R——減速器實際輸出轉(zhuǎn)矩。N·m。
(3)初選好減速器的規(guī)格后,還應(yīng)校核減速器的最大尖峰載荷不超過額定承載能力的2.5倍,并按表3.6進(jìn)行減速器輸出軸上作用載荷的校核。
2. 選用示例
試為一建筑卷揚(yáng)機(jī)選擇CW型蝸桿減速器,已知電動機(jī)轉(zhuǎn)速n1=725r/min,傳動比iN=20,輸出轉(zhuǎn)矩T2B=2555 N·m,啟動轉(zhuǎn)矩T2max=5100 N·m,輸出軸端徑向載荷FR=11000N,工作環(huán)境溫度30℃,減速器每日工作8h,每小時啟動次數(shù)15次,每次運(yùn)行時間3min,中等沖擊載荷,裝配型式為第Ⅰ種。
由于給定條件與表3.4規(guī)定的工作應(yīng)用條件不一致,故應(yīng)進(jìn)行有關(guān)選型計算。
由表3.6查得f1=1.2,由表3.7查得f2=1.1,由表3.8計算查得f3=0.93,由表3.9查得f4=1.14,由式(3.4)、式(3.5)計算得:
T2J=T2Bf1f2
=2555×1.2×1.1
=3372.6 N·m
按計算結(jié)果最大值3372.6 N·m及iN=20,n1=725r/min,由表3.4初選減速器為a=200mm,T2=4400N·m,大于要求值,符合要求。
對減速器輸出軸軸端載荷及最大尖峰載荷進(jìn)行的校核均滿足要求,故最后選定減速器的型號為:CW200-20-IF。
