The openings have therein bearing lips to retain axially opposite end surfaces of the rollers, the bearing lips extending inside from an edge around the opening at locations corresponding with diametrically opposite ends of the major axis. The bearing lips end into wedged bearing edges deformable elastically. The bearing edges have bearing slants adapted to conform to the end surfaces of the roller to bear the roller thereon. The bearing slants are in diametrically symmetric relation to each other. | 2012-01-19 |
20120014629 | Porous hydrodynamic bearing - There is provided a porous hydrodynamic bearing including a sleeve supporting a shaft, wherein the sleeve is formed of a sintered body containing at least one metal powder selected from a group consisting of SUS 304, SUS 430, and iron (Fe). In the sleeve formed of the sintered body containing at least one metal powder selected from the group consisting of SUS 304, SUS 430, and iron (Fe), surface pores and inner pores are not in communication with each other, whereby a leakage phenomenon of dynamic pressure may be reduced, as compared to a sleeve made of an alloy of Cu and Fe in which opened pores are formed. | 2012-01-19 |
