Key words : Chain conveyor Tensioning device Performance Structure Design The chain type transports the machine with the chain a conduct and actions loading with lead the organization completes the material of transport the work.The chain belongs to the gentle lead organization , its characteristics is to loads the ability strong, bear to negative heavy the hour the amount of elongation small; can round the diameter smaller chain round, lead round, pulley and tail round; can is above it to fix very and expediently every kind of transport a piece.It leads with another gentle lead the organization and belt conveyer is similar, all needing to bring to the stretch to regulate the device, transporting otherwise machine cant normal work. therefore, bring to the stretch the device is a chain type to transport the indispensable importance in machine constitutes the part. its usually establishes at transport the machine. 1.The function tensioning device 1The chain packs in to transport the machine empress, ising flabby under the situation of diding not is brought to the stretch, cant normal work, only make its winning prepared to bring to the stretch the dint namely early tension certainly, then can make transport the normal movement in machine. 2Usually transport the tail a friction for is all passive round, depending with chain an of the machine make its revolve.Only passing to bring to the stretch device then can make lead a friction for ising enough and big with tail a creation arouses the tail rotates to move, this for light an and take the tail round of the slot light an is particularly for importance. 3 the chain a stanza is apart from to become gradually big because of wear and tear, the c
