Abstract

L'invention a pour but d'apporter une solution au problème des bagues élastiques de type E, de la technique antérieure, lié au fait que de telles bagues élastiques sautent aisément et que la fixation et l'enlèvement de celles-ci est difficile. A cet effet, il est prévu, dans la bague élastique selon l'invention, une pluralité d'encoches intérieures (3, 3a, ) et de saillies (4, 4a, ) qui sont formées en alternance sur la partie circonférentielle interne du matériau de base en forme de C, muni d'une ouverture (1) en un emplacement de la partie circonférentielle externe ; en outre, des encoches extérieures (5, 5a, ) sont formées aux emplacements de la partie circonférentielle externe correspondant aux parties situées entre les encoches intérieures (3, 3a, ), l'ouverture (1) étant élargie vers la face circonférentielle externe. Du fait que la bague est déformée élastiquement facilement, sans requérir une force plus que nécessaire au moment de la fixation et de l'enlèvement, la bague élastique pour arbre peut être fixée et retirée facilement, tout en l'empêchant de sauter brusquement, notamment au moment de la fixation.
