  • Dynamics of Machine Tool Spindle/Bearing Systems

    2017-2-7 · The small gap between the analytical result and the experimental data at the spindle speed of 2000 r/min is caused by the increment in the bearing preload. In addition, spindle stiffness is proportional to bearing stiffness, and the relationship between the bearing stiffness and preload can be observed in Figure 18, which illustrates that a larger bearing preload results in greater spindle stiffness. So far, the method employed in this article combines the bearing temperature rise, bearing ...
