SCWU軸裝式圓弧圓柱蝸桿減速機性能介紹

日期:2014-05-20 17:41點擊:

 SCWU軸裝式圓弧圓柱蝸桿減速機(JB/T6387 — 1992)直接套裝在工作機主軸上,包括 SCWU ,SCWS,SCWO 三個系列。工作條件:減速器蝸桿軸轉速不超過 1500 r/min;工作環境溫度為- 40~40 ℃,當工作環境溫度低于0 ℃時,啟動前潤滑油   加熱到0 ℃以上;減速器可正、反向運轉。

SCWU減速機蝸桿導程角()是蝸桿分度圓柱上螺旋線的切線與蝸桿端面之間的夾角,與螺桿螺旋角的關系為,蝸輪的螺旋角,大則傳動,當小於嚙合齒間當量摩擦角時,機構自鎖。
引入蝸桿直徑系數q是為了限制蝸輪滾刀的數目,使蝸桿分度圓直徑進行了標準化m   時,q大則大,SCWU減速機蝸桿軸的剛度及強度相應增大;   時,q小則導程角增大,傳動效率相應提高。
SCWU軸裝式蝸輪蝸桿減速機構的特點
SCWU軸裝式蝸輪蝸桿減速機可以很大的傳動比,其承載能力高於交錯軸斜齒輪機構蝸桿傳動相當於螺旋傳動,為多齒嚙合傳動,故傳動平穩、噪音很小具有自鎖性。當蝸桿的導程角小於嚙合輪齒間的當量摩擦角時,機構具有自鎖性,可實現反向自鎖,即只能由蝸桿帶動蝸輪,而不能由蝸輪帶動蝸桿。如在其重機械中使用的自鎖蝸桿機構,其反向自鎖性可起   保護作用傳動效率較低,磨損較嚴重。蝸輪蝸桿嚙合傳動時,嚙合輪齒間的相對滑動速度大,故摩擦損耗大、效率低。另一方面,相對滑動速度大使齒面磨損嚴重、發熱嚴重,為了散熱和減小磨損,常采用價格較為昂貴的減摩性與抗磨性較好的材料及良好的潤滑裝置,因而成本較高。
SCWU軸裝式減速機傳動比計算方法:
I=n1/n2=z/K
n1-蝸桿的轉速  n2-蝸輪的轉速  K-蝸桿頭數  Z-蝸輪的齒數
