A DK conveyor chain has a structure, and also the names from the parts are stated during the drawing. These parts have functions specified beneath.
Pins
Pins help the many load acting on the chain together with plates, and when the chain is engaged with the sprockets, they slide along with bushings as bearings. They are really topic to put on and especially must have large shear strength, bending strength and put on resistance. Hardened and tempered hard steel, carburized steel, or induction-hardened steel is used.
Rollers
Rollers shield the chain from shocks with the sprockets, and once the chain is engaged using the sprockets, the rollers bend the chain smoothly and act to reduce the resistance once the chain runs on a rail. They are really needed to get high shock fatigue power, collapse strength and wear resistance. Hardened and tempered tough steel, carburized steel or induction-hardened steel is employed.
Bushings
Bushings are situated concerning pins and rollers and act as bearings for both the pins and rollers to not transmit the load obtained from the rollers immediately to the pins when the chain is engaged together with the sprockets. They can be expected to have high shock fatigue power, collapse power and wear resistance, and on the whole, carburized steel is applied.
Plates
Plates are topic to repeated stress in the chain and often to massive shocks. They can be essential to have high tensile strength, and particularly high shock strength and fatigue strength. Large tensile steel is utilised for normal chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins reduce the outer plates from disengaging from the pins. They are manufactured from soft steel given that pins are typically pressed-in the outer plates and consequently no huge force acts within the T-pins.
