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。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、運輸、化工、建筑、建材、能源、輕工等行業(yè),是應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,或采用低凝固點的潤滑油,當工作溫度高于40℃時,必須采取冷卻措施;減速器可正反向運轉(zhuǎn)。

表3.6中的FR是根據(jù)外力作用于輸出軸軸端的中點確定的,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)
當外力作用點偏離中點△L時,其許用徑向載荷應由式(3.1)確定:
式中的正負號分別對應于外力作用點由軸端中點向外側(cè)及內(nèi)側(cè)偏移的情形。

2.選用方法
(1)選用減速器應已知原動機、工作機類型能參數(shù)、載荷性質(zhì)及大小、每日運行時間、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,應由式(3.2)~式(3.5)進行修正計算,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
試為一建筑卷揚機選擇CW型蝸桿減速器,已知電動機轉(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)定的工作應用條件不一致,故應進行有關(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行的校核均滿足要求,故最后選定減速器的型號為:CW200-20-IF。
