    微耕機傳動比分配的基本原則
    時間:2014-11-27 來源:微耕機 作者:管理員

     

      微耕機是一種高效實用的新型鏈條式開溝培土裝置,今天小編為大家介紹的是微耕機傳動比分配的基本原則:
     
      1、各種傳動的傳動比,均有其合理應用的范圍,通常不應超過;
     
      2、各級傳動的承載能力近于相等;
     
      3、各級傳動中的大齒輪浸入油中的深度大致相近,從而使潤滑最為方便;微耕機
     
      4、分配傳動比時,應注意使各傳動件尺寸協調、結構勻稱,避免發生相互干涉。 如設計二級齒輪減速傳動時,若傳動比分配不當,可能會導致中間軸大齒輪與低速軸發生干涉;
     
      5、對于多級減速傳動,可按照“前小后大”(即由高速級向低速級逐漸增大)的原則分配傳動比,且相鄰兩級差值不要過大。這種分配方法可使各級中間軸獲得較高轉速和較小的轉矩,因此軸及軸上零件的尺寸和質量下降,結構較為緊湊。增速傳動也可按這一原則分配;
     
      6、在多級齒輪減速傳動中,傳動比的分配將直接影響傳動的多項技術經濟指標。例如:傳動的外廓尺寸和質量很大程度上取決于低速級大齒輪的尺寸,低速級傳動比小些,有利于減小外廓尺寸和質量。 
     
      閉式傳動中,齒輪多采用濺油潤滑,為避免各級大齒輪直徑相差懸殊時,因大直徑齒輪浸油深度過大導致攪油損失增加過多,常希望各級大齒輪直徑相近。故適當加大高速級傳動比,有利于減少各級大齒輪的直徑差。
