Abstract

An overrunning radial coupling assembly having dual bearing support is provided. The assembly includes an inner member having an outer peripheral surface and an outer member having an inner peripheral surface adjacent the outer peripheral surface in radially inner and radially outer relationship. At least one of the members is mounted for rotation about an axis. One of the members includes pockets angularly spaced about the axis. Each of the pockets has a closed end and an open end located axially opposite the closed end. The assembly further includes a plurality of pawls. Each of the pawls is located in a pocket and is supported to pivot toward the peripheral surface of the other of the members. The assembly still further includes a retainer secured to one of the members. The retainer covers the open end of the pockets. The inner and outer peripheral surfaces define a first radial bearing interface adjacent the closed end of each of the pockets. The retainer has a bearing surface which together with one of the peripheral surfaces define a second radial bearing interface adjacent the open end of each of the pockets. The first and second radial bearing interfaces react and carry an internal moment load to prevent contact of the peripheral surfaces during overrunning.
