Patent ID: 8789880

Claim:
Link chain comprising: two or more rows of chain elements, wherein the chain elements of one row are rotatably connected to those of the adjacent row in a chain plane in such a manner that each chain element has two rotational axes; wherein each one of the two rotational axes of two different chain elements is in adjacent rows; toothing arrangements on facing ends of said chain elements interconnecting the chain elements of one row wherein the chain is flexible in the chain plane, wherein the rotational axes are configured in such a manner that the chain responds to a force that applies a turning moment to the axes to move to an adjusted position and remains in the adjusted position when the force is reduced and wherein the turning moment of the rotational axes is adjustable, wherein the rotational axes comprise a synthetic material disk and a synthetic material bushing, wherein the synthetic material disk and the synthetic material bushing are formed elastic synthetic material and wherein the synthetic material disk and the synthetic material bushing of the rotational axes are compressed by an adjustable amount of compression to thereby adjust the tuning moment of the rotational axes.
