The oil supply hole penetrate the carrier ring from the outer peripheral side to an inner peripheral side and extends toward a rear side in a rotational direction of the rotating shaft as the oil supply hole goes radially inward with respect to the axis. | 2020-08-20 |

20200263737 | SLIP-BETWEEN-CENTER PROPELLER SHAFT ASSEMBLY WITH RADIAL THRUST RINGS - A propeller shaft assembly including a first shaft that presents a plurality of external splines, and a second shaft that has an internal wall which defines an axial bore. The axial bore receives the first shaft and presents a plurality of internal splines that are interleaved with the external splines of the first shaft for providing relative axial movement between the first and second shafts while rotationally fixing the first and second shafts to one another. At least one thrust ring is positioned against the internal wall of the second shaft and surrounds the external splines of the first shaft. The at least one thrust ring has at least one contact portion that is radially deformed in a bending manner against the external splines for causing a radial preload against the external splines. The at least thrust ring extends between a pair of ends that are disposed in spaced relationship with one another to define a gap between the ends. | 2020-08-20 |
