U.S. TSUBAKI ATTACHMENT CHAIN SELECTION GUIDE
Attachment Chain Selection Guide SELECTION PROCEDURE Step 3
Calculate chain tension Next, the chain tension should be calculated using the actual weight of the conveyor chain and material conveyed, as shown below.
U.S. Tsubaki ASME/ANSI single and double pitch roller chain is widely used for conveyor service. The following procedure is useful for economical and quick chain selection. Step 1 : Confirm the operating conditions of the conveyor Step 2 : Tentatively select the chain size Step 3 : Calculate the design chain tension (actual chain tension) Step 4 : Verify the chain selection Step 5 : Verify the allowable roller load Step 1 Confirm the operating conditions of the conveyor The following information is needed to design a chain conveyor. Type of conveyor (slat conveyor, bucket elevator, etc.) Method of chain travel (horizontal, inclined, or vertical conveyor) Type, weight, and size of materials to be conveyed Weight of materials to be transported per foot of conveyor length
1. Chain rolling
Conveyor speed Conveyor length Lubrication Considerations for special environments
Step 2 Tentatively select chain size To tentatively select the chain size, estimate the chain tension (T) by the following formula. A chain with an allowable load equal to or over the above calculated chain tension may be tentatively selected. T (lbs.) = M T • f • k 1 ................ (1)
M T : Total weight of material conveyed (lbs.) f : Coefficient of friction, sliding and/or rolling (f 1 and/or f 2 of Table I and II) k 1 : Chain speed coefficient (Table III)
