The roller may have a first end, a second end, and a convex surface defined between the first end and the second end along a length of the roller. The convex surface of the roller includes a groove defined along an apex portion of the convex surface. The groove may support an O-ring, and the convex surface may support a flat belt mounted over the O-ring in the groove. 本发明题为"具有凹槽顶点的凸面辊"。本发明描述了一种用于输送机的辊。该辊可以具有第一端、第二端和沿该辊的长度限定在该第一端和该第二端之间的凸面。该辊的该凸面包括沿着该凸面的顶点部分限定的凹槽。该凹槽可以支撑O形环，并且该凸面可以支撑安装在该凹槽中的该O形环之上的平带。
