Capacity enhancement in HDD conical micro-bearings
Journal Title: Tribologia - Year 2009, Vol 226, Issue 4
Abstract
This paper presents a method of pressure and carrying capacity calculation in slide conical micro-bearing occurring in HDD computer discs. The authors compare they’re own results of pressure and capacity distributions with the results that are obtained G.H. Jang. Considered microbearings have intelligent memory features. G.H. Jang attain memory properties through the nano- grooves on the cylindrical micro-bearing surfaces which implies the whirling motion and whirling flows of the lubricant in the bearing gap. In the presented paper, the proper pressures and capacity distributions and memory effects the of course are obtained by the conical shapes of the journal and sleeve and additionally by the grooves with depth of about 25 nm. Such shapes increase and regulate the pressure and capacity distributions and the effect of whirling motion and therefore increase the bearing memory properties.<br/><br/>
