The invention provides an escalator roller. The escalator roller comprises a rolling bearing, a metal core and a plastic rim; a bearing seat is arranged in the metal core and used for installing the rolling bearing, and stop pieces are arranged on the two sides of the bearing seat and used for axially fixing the bearing; the plastic rim is arranged on the outer side of the metal core in the circumferential direction; the plastic rim is made of first plastic; a plastic hub is further arranged between the metal core and the rim and is made of second plastic; annular grooves are formed in the two sides of the metal core correspondingly, and the annular grooves are symmetrical, so that the cross section of the metal core is I-shaped; and on the cross section, the open end of each annular groove is roughly rectangular, and the closed end of each annular groove is rounded. According to the escalator roller, the noise in the running process of the roller is lowered, the stability of the roller is improved, the cracking of the outer ring is effectively prevented, and meanwhile, the cost of the roller is reduced under the condition that the bearing capacity strength of the roller is not reduced.
本发明提供一种自动扶梯滚轮,包括:滚动轴承、金属芯和塑料轮缘。其中,金属芯中设有轴承座,用于安装该滚动轴承,轴承座的两侧设有止挡件,用于将轴承轴向固定;而该塑料轮缘设置在金属芯的周向外侧;所述塑料轮缘由第一塑料制成;在金属芯和轮缘之间还设有塑料轮毂,所述塑料轮毂由第二塑料制成。在金属芯的两侧,还各自设置有环形凹槽,环形凹槽是对称的,使得金属芯的横截面呈“工”字形;在横截面上,环形凹槽的开放端呈大致矩形的形状,其封闭端呈倒圆形状。通过本发明,降低了滚轮运行过程中的噪音、提高了滚轮的稳定性、有效防止了外圈的开裂,同时还在不降低滚轮承载力强度的情况下降低了滚轮的成本。
