微耕机传动比分配的根本准绳
时间:2014-11-17 来源:微耕机 作者:管理员

 

  微耕机是一种高效适用的新型链条式开沟培土安装,今天小编为大家引见的是微耕机传动比分配的根本准绳:
 
  1、各种传动的传动比,均有其合理应用的范围,通常不应超越;
 
  2、各级传动的承载才能近于相等;
 
  3、各级传动中的大齿轮浸入油中的深度大致相近,从而使光滑最为便当;微耕机
 
  4、分配传动比时,应留意使各传动件尺寸谐和、构造匀称,防止发作互相干预。 如设计二级齿轮减速传动时,若传动比分配不当,可能会招致中间轴大齿轮与低速轴发作干预;
 
  5、关于多级减速传动,可依照“前小后大”的准绳分配传动比,且相邻两级差值不要过大。这种分配办法可使各级中间轴取得较高转速和较小的转矩,因而轴及轴上零件的尺寸和质量降落,构造较为紧凑。
 
  6、在多级齿轮减速传动中,传动比的分配将直接影响传动的多项技术经济指标。例如:传动的外廓尺寸和质量很大水平上取决于低速级大齿轮的尺寸,低速级传动比小些,有利于减小外廓尺寸和质量。 
 
  闭式传动中,齿轮多采用溅油光滑,为防止各级大齿轮直径相差悬殊时,因大直径齿轮浸油深渡过大招致搅油损失增加过多,常希望各级大齿轮直径相近。故恰当加大高速级传动比,有利于减少各级大齿轮的直径差。
