Embodiment Construction

[0069] Referring now to the drawings and illustrating embodiments, a chain section 10 for transporting products along a transport system, such as a material handling or handling system, includes a pair of side links 12a, 12b and a center link 14 ( Figure 1-3 ). The central link 14 is held between the side links 12a, 12b by a stud or stud-type pin 16 which extends through the central region 14a of the central link 14 and into each side link 12a, 12b. The opening 13 of the opening 13 is held in it by a corresponding fixing piece or nut 18. The stud 16 includes a spherical or annular spherical member 20 generally seated at the midpoint and intermediate region of the shaft portion 16 a of the stud 16 . The chain 10 comprises a plurality of links connected together in a continuous loop around the conveyor system, as is known in the art. To simplify the description, only one group or part of the chain connections are shown, and the other chain connections are basically the same. ...

Abstract

A section of chain for conveying product along a material handling system includes a pin connecting a center link between two side links. The pin may have a sleeve portion around and at least partially along the shaft portion of the pin. The sleeve portion may engage a center link of the section of chain and may be movable relative to the shaft portion. The sleeve portion may comprise a polymeric material. The sleeve portion may be molded over an I-pin or the like, or may be slid or pressed onto a stud-ended pin or bolt or the like. The pin may include a generally spherical-shaped ball member or portion on the shaft portion to enhance flexibility of the section of chain. The pin may be dialable or selectably positioned at the side links to control and adjust the wear surface of the pin relative to the chain links.

Description

technical field [0001] The present invention relates generally to chains of transmission systems and, in particular, to tethered or pinned chains allowing pivotal movement between a central chain and a pair of side chains about an axis defined by a bolt or pin extending therefrom. Background technique [0002] Chains used in power transmission or material handling systems, such as chains used to move multiple rollers or the like along a path in a processing plant, warehouse, etc., bend as the chain travels along a predetermined path. As the chain travels along a desired path, the chain may deform to turn sideways and / or bend up or down along the path, and links of the chain may move relative to pins or bolts that Define the joints of the chain. The relative movement of the links and the pins or bolts causes wear on the components and eventually leads to failure of the chain and / or the pins or bolts. Wear may increase if friction between the pins and links increases, such a...
