Analysis of the harmonics losses and bearing load for motorized high speed spindle part I: Modeling

Abstract: Angular contact bearings are the most popular type of bearings used in the motorized high speed spindle. An initial preload and operating-induced load control are managed to ensure its rigidity, but the centrifugal force and temperature will rise with the rapid increase of spindle speed. Although the centrifugal force and thermo induced bearings load are applied on the spindle assembly. This paper aims to study innovative structure solution of spindle and develop a new type of super precision bearings which wi… Show more

“…Therefore, it was impossible to conduct the reliability test for a long time period. JS Chen and KW Chen 10 and SC Chen et al 11 developed two kinds of loading test systems for the motorized spindle using the mechanical spring and hydraulic cylinder. However, the accuracy of the dynamic and static performance was affected evidently by the friction that occurred between the tested spindle and the loading device.…”

“…Based on researches, we can conclude that the proportion of comprehensive displacement of machine processing resulting from spindle parts accounts for 60%~80% of total displacement errors [1][2] . Hence, it is great significance to analysis the static and dynamic characteristics of turning center's spindle [3][4] .…”
