  Calculation For Slewing Ring
     AddTime:2008-7-9
 

匯、Calculation for single-row ball slewing ring
1、Capacity of slewing ring
 C0 = f ,D,d
 In EqualityCo !!Capacity of bearing N
        f !!Capacity factor 110 N / mm2
        D !!Diameter of track center mm
        d !!Diameter of ball mm
2、Loading calculation
  Cp = P + 4370 MD + 3.44 Fr
  In EqualityCp !!Loading caculation kN
        M !!Toppling movement kN,m
        Fa !!Axial force kN
        Fr !!Radial force kN
3、Safety factor calculation
  fs = Co / Cp
   fs see the following table。
屈、 Calculation for 3-row-roller slewing ring bearing
1、Capacity of slewing ring
  C0 = f ,D,d
  In EqualityCo !!Capacity of bearing N
        f !!Capacity factor 147N / mm2
        D !!Diameter of track centermm
        d !!Upper row roller diametermm
2、Loading caculation
   Cp = P + 4500 MD
    In EqualityCp !!Loading caculationkN
        M !!Toppling movement kN,m
        Fa !!Axial forcekN
3、Safety factor calculation
  fs = Co / Cp
  fs see the following table 。
