Abstract

L'invention concerne un accouplement de transmission à vis et écrou à billes. Dans cet accouplement la vis est une vis flexible constituée par un ressort hélicoïdal précompressé, selon le brevet principal, le ressort hélicoïdal précompressé est constitué par un élément filiforme enroulé sous la forme d'une hélice cylindrique et ayant une section d'une forme telle que l'élément définisse, entre deux spires en contact l'une avec l'autre, une gorge hélicoïdale extérieure dont le pas est égal au pas du ressort et dont la section est sensiblement semi-cylindrique. L'invention s'applique à la réalisation d'accouplement de transmission.
