Load Carrying Capacity of Microbearings with Parabolic Journal

Abstract:

Article Preview

This paper presents the load carrying capacity (load capacity) and friction coefficient calculation of hydrodynamic HDD micro-bearing with parabolic profile of journal. One of the reason of such journal profile is that this journal profile contributes to the variation (an increase or decrease) the memory capacity of HDD drive operating on hydrodynamic micro-bearings. Such properties are very important and required in HDD micro-bearings. Up to now, the dynamic behavior of HDD spindle system with fluid micro-bearings was considered by Jang at al. [3]. They simulated an increase in the memory capacity by increase in the bearing width and by application herringbone or spiral grooves on the sleeve and journal surfaces of HDD micro-bearings.
