A chain link for a roller chain or a sleeve-type chain that has a plurality of link plates with openings for receiving chain sleeves that can be brought into engagement with a sprocket wheel to transmit force. The chain sleeve has a central region that is engaged with the sprocket wheel and that has a larger outer diameter than its end regions that are held in the link plate openings. A method is disclosed for producing a chain sleeve for a chain link of a chain, which is produced by deep drawing, or by machining.

Chain link and chain sleeve of a chain, and method for producing a chain sleeve

A method or producing rollers and sleeves for chains, particularly for roller chains or sleeve-type chains. The rollers and sleeves are of cylindrical form and they are deep-drawn from a sheet metal material. The drawn components can remain attached to the sheet metal for convenience in transporting them and later separated from the sheet as they are needed. Alternatively, the drawn components can be separated from the sheet metal material and can be pressed into the openings that remain in the sheet metal, again for convenient transportation.
