Patent attributes
A roller chain is provided, which is composed of more than one roller and a carrier belt. The roller chain helps make sure of keeping the rollers against moving on the skew even under carrying high loads while the carrier belt is made to have a large space to reserve lubricant sufficient to ensure good lubrication. The carrier belt is comprised of a pair of continuous bands lying to carry or bear axially opposite ends of the roller across an area set off-center from an axis of the roller, and more than one U-type separator to join the continuous bands together with one another. The U-type separators 6 are each composed of a pair of legs joined together with their associated continuous bands, and a horizontal bridge interconnecting the sidewise spaced leg with each other.
