Title (EN) METHOD AND APPARATUS FOR GRINDING PISTON RINGS
(FR) METHODE ET APPAREIL DE RODAGE DES SEGMENTS DE PISTON
Abstract: front page image
(EN)A method and apparatus for grinding a split piston ring (10) having at least one inwardly converging top or bottom wall member (16, 18) by bringing such wall into engagement with a rotating grinding member (45) having a spherical segment working surface (45a), the path of relative movement being along a line which is coincident with the axis (10a) of the piston ring (10) and also coincident with a radius of the spherical surface (45a) of the grinding member (45), whereby all of the inwardly converging surface (16, 18) of the split piston ring (10) is concurrently ground to conform to the curvature of the spherical segment surface (45a) of the grinding member (45).
(FR)Methode et appareil de rodage d"un segment de piston fendu (10) ayant au moins un sommet convergeant vers l"interieur ou un membre de paroi de fond (16, 18), consistant a amener une telle paroi en engagement avec un organe de rodage rotatif (45) ayant une surface de travail a segment spherique (45a), le chemin du mouvement relatif se faisant suivant une ligne qui coincide avec l"axe (10a) du segment de piston (10) et qui coincide aussi avec un rayon de la surface spherique (45a) de l"organe de rodage (45), de maniere a ce que la surface convergeant vers l"interieur (16, 18) du segment de piston fendu (10) soit rodee en adoptant la courbure de la surface de segment spherique (45a) de l"organe de rodage (45).
