Get Price1994-9-15u2002·u2002The example in the diagram, figure 6, shows a comparison of bearings for a high speed internal grinding spindle. At a speed of 40,000 r/min the radial stiffness of a particular hybrid bearing has been reduced to 70 % of the static stiffness, while for a comparable bearing with steel balls the stiffness has been reduced to 61 %.
Get Price1998-5-1u2002·u2002Previous spindle-bearing models simplify either spindle or bearing dynamics to the extent of prohibiting a detailed analysis of a spindle with high speed motion. At high speeds, centrifugal loading in the bearing causes stiffness softening, creating a change in natural frequency. Therefore, spindle modeling requires a comprehensive ...
