The present invention relates to a chain (10) comprising an alternating succession of inner chain links (14) and outer chain links (16), each inner chain link (14) having a pair of inner link plates (18) contacting the lateral faces of two rollers (30) and each outer chain link (16) having a pair of two outer link plates (20, 20') contacting the inner link plates (18) of adjacent inner chain links (14). A pin (32) connects two outer link plates (20) and two inner link plates (18) and a roller (30), wherein the inner surfaces (26) of a pair of opposite outer link plates (20, 20') comprise protrusions (36) in the area between the adjacent inner link plates (18). The circumference and/or diameter of the protrusion is at least 60% and/or maximum 140% the circumference and/or diameter of the eyes (60) of the outer link plate.
本发明涉及一种链条(10),包括交替连续的内链节(14)和外链节(16),每个内链节(14)具有接触两个滚子(30)的侧面的一对内链节板(18),且每个外链节(16)具有接触相邻内链节(14)的内链节板(18)的一对两个外链节板(20、20')。销(32)连接两个外链节板(20)和两个内链节板(18)和滚子(30),其中一对相对的外链节板(20、20’)的内表面(26)包括在相邻的内链节板(18)之间的区域中的凸起(36)。凸起的圆周和/或直径为外链节板的孔眼(60)的圆周和/或直径的至少60%和/或最大140%。
