Abstract
(EN)
This method of acquiring a contact angle of an angular contact ball bearing comprises: a first detection step for detecting the rotational speed of one raceway ring 12 of an angular contact ball bearing 10; a second detection step for detecting, from the outside, the deformation of the other raceway ring 11 according to the revolution of a ball 13 of the angular contact ball bearing 10; and a calculation step for obtaining a contact angle α of the ball 13 by using the detection result of the first detection step, the detection result of the second detection step, and specification data of the ball 13.
(FR)
Cette invention concerne un procédé d'acquisition d'un angle de contact d'un roulement à billes à contact angulaire, comprenant : une première étape de détection consistant à détecter la vitesse de rotation d'une bague de chemin de roulement (12) d'un roulement à billes à contact angulaire (10) ; une seconde étape de détection consistant à détecter, à partir de l'extérieur, la déformation de l'autre bague de chemin de roulement (11) en fonction de la révolution d'une bille (13) du roulement à billes à contact angulaire (10) ; et une étape de calcul consistant à obtenir un angle de contact alpha de la bille (13) à l'aide du résultat de détection de la première étape de détection, du résultat de détection de la seconde étape de détection, et de données de spécification de la bille (13).
