单排球式回转支承的造型计算Calculation for single-row ball slewing ring bearing:
1、计算回转支承的额定静容量capacity of slewing ring bearing
    Co=f·D·d
   式中:
Co额定静容量,N(capacity of bearing)   f静容量系数,110N/mm2(capacity factor)
  D滚道中心直径,mm(diameter of track center)d钢球公称直径,mm(diameter of ball)。

  2、根据组合后的外载荷,计算当量轴向载荷loading calculation
     Cp=P+0.00437M/D+3.44Fr
    式中:
Cp-当量轴向载荷,N   M-总倾覆力矩,N·m(total toppling movement)
   P-总轴向力,N(total axial force) Fr-总径向车,N(total radial force)。
3、计算安全系数(safety factor calculation)
     fs=Co/Cp
    fs值可按下表选取(see the following table)。
三排柱式回转支承的造型计算Calculation for 3-row-roller slewing ring bearing:
1、计算额定静容量capacity of slewing ring bearing
     Co=f·D·d
    式中:

  D-滚道中心直径,mm(diameter of track center)   d-上排滚柱直径,mm(upper row roller diameter)
2、根据组合后的外载荷,计算当量轴向载荷loading calculation
Cp=p+0.0045M/D
式中:
Cp-当量轴向载荷,    N        M-总倾覆力,N·m(total toppling movement)
P总轴承向力,N(total axial force)
3、计算安全系数(safety factor calculation)
fs=Cp/Cp
fs值可按下表选取(see the following table);
