WebIn Figure 15 the shear force in the lubrication film is plotted for three different cavity depths. As shown, the shear force decreases when the dimple depth increases from 8 to 22.8 μm. The result is lower friction and thus a reduced friction coefficient. Thus, a minimum value of F x = 0.46 N is found for a cavity depth of 22.8 μm. However to ...
