Abstract

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.

Claims (3)

1. A method for producing rollers and sleeves for roller chains and sleeve-type chains, including the steps of: providing a sheet metal material; deep-drawing components in the form of at least one of rollers and sleeves from the sheet metal material; separating the deep-drawn components from the sheet metal material; and pressing the separated components into openings in the sheet metal material that result from the separation.

2. A method in accordance with claim 1 , including the step of removing the components from the sheet metal material at the end of fabrication.

3. A method in accordance with claim 1 , including the step of fabricating the components in a plurality of paths that are parallel to each other.
