Abstract
(EN)
A full crowning formed on the outer diameter surface (13) of a roller (11) has a first crowning (14a), second crownings (14b), and third crownings (14c). When the length of the roller (11) in the direction of its rolling axis is not more than twice the radial length of the roller (11), the radius R1 of the curvature of the first crowning (14a) at a position apart by 32% of the length of the roller in its rolling axis direction from an end face (12a) of the roller (11) is from R551 to R1000, the radius R2 of the curvature of a second crowning (14b) at a position apart 23% of the length of the roller in its rolling axis direction from the end face (12a) of the roller (11) is from R321 to R550, and the radius R3 of curvature of a third crowning (14c) at a position apart 15% of the length of the roller in its rolling axis direction from the end face (12a) of the roller (11) is from R200 to R320.

La présente invention concerne la couronne entière formée sur la surface de diamètre extérieur (13) d'un rouleau (11) qui possède une première couronne (14a), des deuxièmes couronnes (14b), et des troisièmes couronnes (14c). Lorsque la longueur du rouleau (11) dans la direction de son axe de roulement n'est pas supérieure à deux fois la longueur radiale du rouleau (11), le rayon (R1) de courbure de la première couronne (14a) dans une position séparée par 32 % de la longueur du rouleau dans sa direction d'axe de roulement à partir d'une face d'extrémité (12a) du rouleau (11) est de R551 à R1000, le rayon (R2) de la courbure d'une deuxième couronne (14b) dans une position séparée par 23 % de la longueur du rouleau dans sa direction d'axe de roulement à partir de la face d'extrémité (12a) du rouleau (11) est de R321 à R550, et le rayon (R3) de courbure d'une troisième couronne (14c) dans une position séparée par 15 % de la longueur du rouleau dans sa direction d'axe de roulement à partir de la face d'extrémité (12a) du rouleau (11) est de R200 à R320.
