Fatigue Life Prediction for Large-Diameter Elastically

Mar 05, 2008· Therefore, the appliion of large-diameter ball and roller bearing rings as the critical components in rotating machines becomes more of a design task than making a alog selection. The analytical and finite element approach for fatigue life prediction of such a bearing appliion is presented.

Lubricants | Free Full-Text | Field Tests on Hydrodynamic

Oct 31, 2017· In vertical shaft pump turbines operating in pumped storage power plants an important role is played by a thrust bearing. Due to the bidirectional character of operation, thrust bearing tilting pads have to be supported symmetrically, which is known to be unfavourable from the point of view of their performance. Large thrust bearings have to be …
