Fixed-pad thrust bearing
For fixed-pad thrust bearings, the pad is fixed onto the substrate. With micro deformation, oil wedge is formed to generate dynamic pressure. To consider the heat dissipation due to friction, a pair of complete friction faces is divided into several pads circumferentially. This structure of fixed pad is integrated with the substrate, made of ZYTCu-lO. Based on QSn1O-1, the ZYTCu-lO material may improve the PV value, resistance to bonding and wear, and bearing resistance.
The main alloy elements include Cu, Nu, Sn, Pb, Zn, P, etc. This material features good resistance to wear, long life of fatigue, good speed performance, not easy to be seized.
