Conveyor chain link, to travel along curved paths, has a structured joint bolt and joint head with guide surfaces, to allow lateral and vertical swing movements between the links

摘要

The conveyor chain link, to travel along curved paths, has a carrier section (1) with a carrier surface (2) to support the conveyed items, and a lower guide (3) with two side guide surfaces (4) and a lower lateral guide surface. One end, in the direction of travel (6), has two joint eyelets (7) near the side guides to take a joint bolt (8) with its axis parallel to the support surface and across the direction of travel. The free ends (8.1) of the bolt project over the side guides. The other end of the guide has a joint head (9), with a cylindrical opening on an axis at right angles to the support surface. A lateral opening (11) is parallel to the joint bolt. The joint body (12) in the opening has a drilling to take the joint bolt of the neighboring link, with the lateral opening, and extends over the lower guide surface of it neighbor, and the joint eyelets of the adjacent link cover the sides of the joint body.
