Abstract
An epicyclic transmission having first and second confronting surface regions and cylindrical rollers for transmitting torque therebetween includes a two-piece retainer for axially and radially positioning the rollers relative to the confronting surface regions. A first retainer piece includes a top and bottom surface interconnected by a plurality of bars shaped and arranged into pairs for rotatably supporting the rollers so that one end face of the rollers contacts and is supported by the bottom surface. A second retainer piece confronts the top surface so as to support an opposite end face of the rollers.
