Contact Degradation in Tilting of Pivoted Journal and Thrust Pads
Tilting pad radial and thrust bearings are designed with mechanical pivots which introduce minimal resistance to rotation. Recent works have shown the degradation in tilting associated with friction and resisting moments across this contact. For used bearings, deformation or fretting wear on one or both surfaces of the contact has the likelihood of further degrading the circumferential tilting. The impact on deformation on the friction is evaluated using contact mechanics, considering elastic and plastic deformation.
