Abstract
A roller chain that includes a series of alternately arranged inner and outer link units has side links made of wire. The wire side links of the inner unit are welded to the end portions of roller-carrying bushings, and the side links of the outer units are welded to the end portions of pins which extend through the various bushings. An embodiment is disclosed in which the wire links of the outer link units are welded to short sleeves that are pressed onto the pins. Also, a form of the invention involves an arrangement wherein the wire side links of both the inner and outer units are welded to pins and the pins roll on each other to provide the necessary pivoting action of the chain.
