Abstract

Système de refroidissement pour coussinet hydrodynamique d'allure annulaire disposé dans un corps support (7), muni de moyens de distribution d'huile froide sous pression vers un arbre tournant dans le coussinet, caractérisé en ce que le coussinet est constitué d'une coquille annulaire mince (1) dont la surface externe est montée ajustée dans l'alésage dudit corps support (7), des rainures (11) étant pratiquées dans une partie dudit alésage correspondant à la zone angulaire du coussinet sur laquelle s'exerce la charge en fonctionnement, lesdites rainures (11) étant alimentées en huile froide prélevée en aval des moyens de distribution.
