A DK conveyor chain has a structure, and also the names on the parts are stated inside the drawing. These components have functions specified below.
Pins
Pins help every one of the load acting around the chain together with plates, and once the chain is engaged using the sprockets, they slide together with bushings as bearings. They can be subject to dress in and especially must have high shear strength, bending power and dress in resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is employed.
Rollers
Rollers guard the chain from shocks with all the sprockets, and when the chain is engaged with the sprockets, the rollers bend the chain smoothly and act to lessen the resistance once the chain runs on a rail. These are essential to have substantial shock fatigue strength, collapse strength and dress in resistance. Hardened and tempered tough steel, carburized steel or induction-hardened steel is utilized.
Bushings
Bushings are located concerning pins and rollers and act as bearings for both the pins and rollers to not transmit the load obtained by the rollers straight for the pins when the chain is engaged with all the sprockets. They are essential to get higher shock fatigue power, collapse strength and wear resistance, and generally, carburized steel is used.
Plates
Plates are subject to repeated tension in the chain and at times to huge shocks. They can be demanded to have higher tensile strength, and particularly high shock power and fatigue power. Large tensile steel is utilized for regular chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins protect against the outer plates from disengaging through the pins. They can be made of soft steel since pins are usually pressed-in the outer plates and thus no big force acts over the T-pins.
