  • Dynamics Analysis of Unbalanced Motorized Spindles ...

    (c) Figure 10(c) shows the impact of the bearing clearance on the critical speed. Preload makes the bearing in a negative clearance state and improves the stability of the spindle system, which also can reduce the effect of MS. (d) Figure 10(d) shows that the critical speed rises with the increase of ball number. This is because the increase of ...

  • BEARINX -online Spindle Calculation

    The screwed spindle press has a ram which is fitted with a nut (5) to receive the spindle (3). The screw threads of the spindle and of the nut are formed with a clearance between their mating surfaces. This clearance gap is filled with lubricating oil to form a hydraulic bearing. The size of the gap can be differently adjusted over the length of the bearing surface.
