A DK conveyor chain has a framework, and also the names of the parts are stated in the drawing. These elements have functions specified below.
Pins support every one of the load acting to the chain together with plates, and when the chain is engaged with all the sprockets, they slide together with bushings as bearings. They can be subject to dress in and especially should have high shear power, bending power and wear resistance. Hardened and tempered tough steel, carburized steel, or induction-hardened steel is utilised.
Rollers shield the chain from shocks using the sprockets, and once the chain is engaged with all the sprockets, the rollers bend the chain smoothly and act to reduce the resistance when the chain runs on a rail. They can be essential to get high shock fatigue power, collapse strength and dress in resistance. Hardened and tempered difficult steel, carburized steel or induction-hardened steel is employed.
Bushings are found concerning pins and rollers and act as bearings for the two the pins and rollers not to transmit the load received by the rollers directly towards the pins when the chain is engaged together with the sprockets. They are essential to have substantial shock fatigue strength, collapse strength and wear resistance, and in general, carburized steel is utilised.
Plates are subject to repeated stress in the chain and at times to big shocks. They can be necessary to have higher tensile power, and especially higher shock strength and fatigue power. Higher tensile steel is applied for standard chains and heat-treated alloy steel for heavy-duty chains.
T-pins stop the outer plates from disengaging through the pins. They’re made of soft steel since pins are normally pressed-in the outer plates and hence no big force acts around the T-pins.
