Outline of Final Research Achievements

The present study has been carried out to improve the performance characteristics of the electric sliding contacts operating under lubricated condition by a combination of disk with circular grooves and rider with a spherical surface. The results show that increasing the cross-sectional area of the circular grooves on the disk extends the operation condition yielding the metal contact to a region of higher sliding velocity and a lower applied load. These are attributable to the fact that a larger radius of circular groove enhances a leakage of oil lubricant from the contact region to the downstream region through the circular grooves and reduces the oil-film force in the clearance between the rider and disk. The results also show that sliding disks made of porous material used for conventional sintered metal bearings yield more stable current-carrying properties during long period than conventional solid disks.
