Abstract
An epicyclic speed reducing transmission having first and second sets of conjugate epitrochoidal and hypotrochoidal races and first and second sets of rollers transmitting torque between respective sets of races includes a retainer structure for the first and second sets of rollers. The retainer structure is apertured so as to receive the rollers, and independent retainer elements for each set of rollers are provided, with both of these elements being conjointly orbitally driven. The retainer structure may be positively orbitally driven by means of a cam driven spider provided either centrally of or externally of the pair of epitrochoidal races.
