Abstract: A chain, in particular a technical chain, preferably a unidimensionally movable chain (plate link chain), more preferably a bolt chain or roller chain, has at least one or more chain links. The at least one chain link is constructed with pretensioning. A manufacturing method includes the following steps: assembling at least one chain link from at least two link plates with link plate holes and two bolts or sleeves. In the non-assembled state, the link plate is not straight, in particular has a curved form, and/or the link plate and the link plate holes have a hole axis, wherein the hole axis is not right-angled, and/or, in the non-assembled state, the bolt or the sleeve is not straight, in particular has a curved form. The chain is assembled from at least two chain links and at least one chain link is manufactured in this way.

Abstract: A sound-damping unit for a sprocket has a mounting foot for connection to a sprocket and an elastic body placed on the mounting foot that is suitable for cushioning a chain running onto the sprocket. The elastic body is provided with a protective cap or protective layer. A sprocket according to the invention includes a circular sprocket disc having a number of teeth and tooth gaps in the circumferential direction. The sprocket is equipped with at least one sound-damping unit that is configured to reduce the noise upon a chain running onto said sprocket. The sound-damping unit is at least one sound damping unit as above.

Abstract: Drive means for the polygonally-compensated drive of a sprocket, comprising two pulling means wheels (1, 2), a pulling means (3) running on them with an top span (31) and a bottom span (32), and a tensioning means acting on the pulling means (3), wherein the tensioning means comprises a first non-circular compensation wheel (4), which can come into contact with the top span (31), a second non-circular compensation wheel (5), which can come into contact with the bottom span (32), a rocker (6) adapted for rotatably receiving the first compensation wheel (4) and the second compensation wheel (5), wherein the rocker (6) is pivotably supported on a fixed bearing. The invention also relates to a chain drive, comprising at least a sprocket (7), a drive means, wherein the sprocket (7) is driven by the drive means, wherein the drive means is a drive means according to at least one of the claims 1 to 17.
