The invention discloses a step chain roller for a double-injection-molded escalator, relates to the technical field of step chain roller structures, and aims to solve the problems that the adhesiveness of an existing step chain roller for the escalator is poor, and when the existing step chain roller is subjected to external force, a gap is possibly formed between a polyurethane tire bead and a hub; and after a long time, falling and separation may occur. Grooves are formed in the two ends of the hub correspondingly, reinforcing ribs are arranged in the grooves, a bonding end is arranged at one end of the outer wall of the hub, a special-shaped groove is formed in the bonding end, limiting mounting grooves are formed in the two ends of the bonding end correspondingly, and friction stripes are arranged in the outer wall of the bonding end. A bonding end is arranged on one side of the tire body, a polyurethane tire bead is mounted on one side of the bonding end, a special-shaped connecting seat is arranged at one end of the polyurethane tire bead, limiting mounting ends are arranged on the two sides of the polyurethane tire bead, and a limiting clamping seat is arranged at one end of each limiting mounting end.

    本发明公开了一种双注塑自动扶梯用梯级链条滚轮,涉及梯级链条滚轮结构技术领域,为解决现有的自动扶梯用梯级链条滚轮的粘合性不好在受到外力时,聚氨酯胎圈可能会与轮毂之间出现缝隙,时间长久后可能出现脱落分离的情况问题。所述轮毂的两端均设置有凹槽,所述凹槽的内部设置有加强筋,所述轮毂外壁的一端设置有粘合端,所述粘合端的内部设置有异型槽,所述粘合端的两端均设置有限位安装槽,所述粘合端外壁的内部设置有摩擦条纹,所述粘合端的一侧安装有聚氨酯胎圈,所述聚氨酯胎圈的一端设置有异型连接座,所述聚氨酯胎圈的两侧设置有限位安装端,所述限位安装端的一端设置有限位卡座。
