Fig. 11 shows the experimental data obtained for the pivot-supported bearing. In the performance test (Fig. 11(a)), except the large friction coefficient caused by contact friction at low speed (100 r min−1) and heavy load (0.4, 0.5 MPa) conditions, the variation of the friction coefficient is as expected, which decreases with the increase of the load, but decreases first and then rises with the increase of the speed. In the durability test (Fig. 11(b)), the friction coefficient remained below

Aiming at the demand of marine shaft-less rim-driven thrusters(RDTs) for high load capacity, long life, low friction and low vibration water lubricated hydrodynamic thrust bearings(WLHTBs), three types of WLHTBs were designed and manufactured: pivot-supported, rubber-supported and fixed pads bearings. A series of experiments were carried out to study their tribological and vibration performance. Axial force, friction torque, axial displacement of the thrust collar, water temperature and vibration characteristics under different working conditions were acquired by a load cell, a torque meter, 4...
