Shambon Type Selection Calculation
一、Calculation for single-row ball slewing ring 1、Capacity of slewing ring C0 = f ·D·d In Equality:Co ——Capacity of bearing ,kN f ——Capacity factor ,0.108 kN / mm2 D ——Diameter of track center ,mm d ——Diameter of ball ,mm 2、Loading calculation
In Equality:Cp ——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。 二、 Calculation for 3-row-roller slewing ring bearing 1、Capacity of slewing ring C0 = f ·D·d In Equality:Co ——Capacity of bearing ,kN f ——Capacity factor ,0.172 kN / mm2 D ——Diameter of track center,mm d ——Upper row roller diameter,mm 2、Loading caculation In Equality:Cp ——Loading caculation,kN M ——Toppling movement ,kN·m Fa ——Axial force,kN 3、Safety factor calculation fs = Co / Cp fs see the following table 。 Slewing ring safety factor fs
