The invention discloses an escalator roller. The escalator roller comprises a bearing capable of rotating around the rotation axis of the roller, a wheel body, a wheel flange, a first side surface, a second surface and grooves, wherein the wheel body and the wheel flange are both located on the bearing capable of rotating around the rotation axis, the first side surface and the second side surface are perpendicular to the rotation axis, and the grooves repeatedly appear on the first side surface and the second side surface on the wheel body in the radial direction; each of the first side surface and the second side surface has two end regions and one or more intermediate regions, wherein one end region is located around the bearing and the other end region is located near the wheel flange, and the one or more intermediate regions are arranged between the end regions; a distance between the first side surface and the second side surface is smaller in the intermediate regions than an end region forming an inner arc surface on a common region of pillars.
一种自动扶梯滚轮,包括:可绕滚轮的旋转轴线旋转的轴承和轮体以及轮缘,两者都位于可绕旋转轴线旋转的轴承上;垂直于旋转轴线的第一和第二侧表面以及轮体上在第一和第二侧表面上径向重复出现的凹槽,其中,第一和第二侧表面都具有两个端部区域,一个位于轴承周围,并且一个位于轮缘附近,以及布置在端部区域之间的至少一个中间区域,第一和第二侧表面之间的距离在中间区域比在支柱的公共区域上形成内弧表面的端部区域小。
