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.

Two-piece retainer for epicyclic transmissions

An epicyclic speed reducing transmission having cylindrical rollers for transmitting torque between first and second confronting surface regions includes a retainer for radially and axially positioning the rollers relative to the first and second confronting surface regions. The retainer includes first and second rings which contain lobes thereon having holes therein which accommodate a series of roller pins. Each of the roller pins has an enlarged roller body portion which rotatably supports the rollers.

Pin controlled retainer for epicyclic transmission

A retainer for retaining and controlling a plurality of rollers rollingly engaging and transmitting torque between conjugate epitrochoidal-like and hypotrochoidal-like races has elongated slots formed therein which function to centrifugally load only those rollers located in a relatively stable position and not centrifugally load other rollers located in an inherently unstable position. Hence, smooth operation of the epicyclic speed reducing transmission is achieved.
