  • Effect of bearing preload on the dynamic

    In order to investigate the effect of the bearing preload on the performance of the spindle, we developed a spindle test rig. In this paper. The effect of bearing preload on the dynamic characteristics of the spindle-bearing system was investigated. The working principle of fixed position preloading method of the spindle-bearing system are introduced.

  • Spindle Bearings, Back Gears, Triple Gear Mechanism.

    In many cases the spindle bearings are lubricated by means of a simple oil hole closed by a plug of brass. In others a short vertical tube is inserted and covered by a cap which entirely encloses it. In still others the 'plain brass oil cup'is used, that is, a simple receptacle, usually urn-shaped, whose top is closed by a cover screwing into it.

  • Thermo-mechanical modeling of high speed spindles ...

    2012-4-1 · For the specific preloading mechanism encountered in this spindle configuration, rear bearings have constant axial load while front bearing axial load varies with speed and time ; however, equilibrium implies that the axial forces be the same in the two front bearings. This time variation is mainly due to the relative thermal expansion of the shaft and housing.

  • Active piezoelectric spindle bearing preload

    One of the variable preload techniques is using clutch principle by adapting the constant position and constant pressure mechanism on the spindle bearing. When the spindle rotates at low speed, the clutch is actuated to switch to the fixed position preload mechanism for providing the bearing a higher rigidity and supporting capacity. When the spindle rotates at high speed, switch to the constant pressure preload mechanism for providing the bearing …
