Abstract

Mécanique. Dispositif destiné à améliorer la lubrification dans un accouplement rotoidal, caractérisé en ce que l'une des surfaces de l'accouplement rotoïdal présente une rugosité réglée, pour permettre la présence dans celle-ci d'un canal capillaire pour l'huile lubrifiante, constitué par un sillon hélicoïdal ou par une série de sillons parallèles. Moteur endothermique.
