|Title:||A bi-directional rotating fluid bearing system||Authors:||Zhang, Q.D.
|Issue Date:||Aug-2002||Citation:||Zhang, Q.D., Chen, S.X., Yang, J.P., Winoto, S.H. (2002-08). A bi-directional rotating fluid bearing system. Microsystem Technologies 8 (4-5) : 271-277. ScholarBank@NUS Repository. https://doi.org/10.1007/s00542-001-0122-1||Abstract:||Most fluid bearing systems with grooves on the journal/thrust bearing surfaces were designed to rotate in a specified direction and cannot be reversed. This feature of such fluid bearings limits their application range and hence, a bi-directional rotating fluid bearing system is proposed. The results of numerical simulation on the dynamic characteristics of such bearing system are presented and compared with those of one-directional rotating fluid-bearing system. It shows that for the same load capacity and stiffness requirement, the bi-directional rotating fluid bearing system has a higher power consumption than that of the one-directional counterpart. However, the bidirectional rotating fluid bearing system provides the freedom of rotating spindle motor in either direction and widens the application range of fluid bearing spindle motors.||Source Title:||Microsystem Technologies||URI:||http://scholarbank.nus.edu.sg/handle/10635/73003||ISSN:||09467076||DOI:||10.1007/s00542-001-0122-1|
