Patent

CA 2621321

This invention relates to epicyclic gears having a carrier (12), a generally central sun gear (11), an outer annular gear (13) and an intermediary helical planet gear (14) which is mounted on the carrier (12) by a flexible pin assembly (15). The gear further includes a reaction member in the form of a rolling ring (22) at each axial end of the helical planet gear (14) to provide a respective radially inward reaction load onto the planet gear (14) in a sense that the reaction members (22) together resist a twisting moment on the planet gear (14) arising from the tooth loads on that gear.

La présente invention concerne des engrenages épicycloïdaux qui comportent un support (12), un engrenage solaire généralement central (11), un engrenage annulaire extérieur (13) et un engrenage planétaire hélicoïdal intermédiaire (14) qui est monté sur le support (12) par un ensemble goupille flexible (15). L~engrenage comprend en outre un élément de réaction sous forme d~anneau roulant (22) au niveau de chaque extrémité axiale de l~engrenage planétaire hélicoïdal (14) pour fournir une charge de réaction respective vers l~intérieur de façon radiale sur l~engrenage planétaire (14) afin que les éléments de réaction (22) résistent conjointement à un moment de torsion sur l~engrenage planétaire (14) entraîné par les charges de dent sur cet engrenage.
