Title (EN) GREASE COMPOSITION FOR BALL-TYPE CONSTANT VELOCITY JOINTS
(FR) COMPOSITION DE GRAISSE POUR JOINT HOMOCINÉTIQUE DE TYPE À BILLES
(JA) ボール型等速ジョイント用グリース組成物
Abstract: front page image
(EN)Disclosed is a grease composition for constant velocity joints, which contains the following components (a to h): (a) a base oil; (b) a diurea-based thickening agent; (c) a zinc dialkyldithiophosphate; (d) a molybdenum dialkyldithiocarbamate; (e) a melamine cyanurate; (f) a calcium carbonate; (g) a zinc dialkyldithiocarbamate; and (h) a sulfur/nitrogen-based extreme pressure additive. The grease composition for constant velocity joints improves abrasion resistance and flaking resistance, by the combination of additives.
(FR)L'invention concerne une composition de graisse pour joint homocinétique de type à billes, laquelle contient les composants (a) à (h) suivants: (a) une huile de base, (b) un agent épaississant de type diurée, (c) un dialkyldithiophosphate de zinc, (d) un dialkyldithiocarbamate de molybdène, (e) un cyanurate de mélamine, (f) un carbonate de calcium, (g) un dialkyldithiocarbamate de zinc ainsi que (h) un additif extrême pression de type soufre-azote. Cette composition de graisse pour joint homocinétique permet d'augmenter la résistance à l'abrasion et à l'écaillage, grâce à sa combinaison d'additifs.
(JA) 本発明により、下記の成分(a)~(h)を含有する等速ジョイント用グリース組成物を提供する。 (a)基油、 (b)ジウレア系増ちょう剤、 (c)ジアルキルジチオリン酸亜鉛、 (d)ジアルキルジチオカルバミン酸モリブデン、 (e)メラミンシアヌレート、 (f)炭酸カルシウム、 (g)ジアルキルジチオカルバミン酸亜鉛、及び (h)硫黄-窒素系極圧添加剤。 本発明の等速ジョイント用グリース組成物は、添加剤の組み合わせにより耐摩耗性を改善し、耐フレーキング性を向上させる。
