木工排钻轴承种类

时间:2019-11-28 02:39:48
  木结构设备木工排钻刚性主轴的设计中对滑动轴承和滚动轴承都采用,但大多数情况下采用是采用滚动轴承,因为滚动轴承具有尺寸小、转速高、寿命长、装配简单、密封和润滑也比较简单,而且可以直接从样本中选用等优点。但是,因为滑动轴承抗震性好,径向尺寸较小,所以在刚性轴设计中经常被采用。在该设计中,由于所设计的木结构设备-木工排钻属于有较小震动的机床,因此选用滚动轴承做为支撑。
 
  1、轴承种类的选用:
 
  排钻设计中,采用滚动轴承的种类很多,根据主轴所受载荷的大小,方向和转速的不同而不同,常采用的滚动轴承有以下几种:单列向心球轴承、单列圆锥滚子轴承,单列向心推力球轴承,双列向心短圆柱滚子轴承、单列推力球轴承单列向心短圆柱滚子轴承等。其中向心轴承主要承受径向载荷,也能承受不大的轴向载荷;推力轴承只能承受轴向载荷;向心推力轴承既能承受轴向载荷,又能承受径向载荷。排钻本设计中,主轴即承受轴向载荷,有承受径向载荷,因此选用单列圆锥滚子轴。
