When you layout various conveyor programs utilizing little conveyor chains, the following basic problems should be content.
a. Chain tension: The actual tensile strength in operation have to be considerably lower than the specified power from the chain.
b. Strength of loaded components of chain: The actual loads utilized to attachments, such as rollers of base chain, top rated rollers, side rollers, etc. in operation should be appreciably smaller compared to the strength of those elements.
c. Wear lifestyle of chain: Lubrication circumstances to make certain the put on daily life of chain should be fulfilled.
d. Sag adjustment of chain: The sag with the chain needs to be stored optimum by tension adjusters, take-up devices, guides, and so on.
e. Some others: Ideal measures are taken to prevent rail wear, machine vibration and other challenges.
The next complement the above.

Calculation of Chain Stress
Usually, at the outset, tentatively determine the chain dimension to get used referring to “Tentative determination of chain size”. Then, acquire “Theoretical chain stress (T)” (P213) for that tentatively determined chain, and multiply the worth by “Speed coefficient (K)”, to acquire “Substantial chain stress (Ta)”. For safety, the considerable chain tension has to be lower compared to the “maximum allowable tension” stated within the table of dimensions of respective chains. Consequently, the condition under should be happy.
Safety condition of chain stress
Considerable chain tension (Ta) =Theoretical chain tension (T) ×Speed coefficient (K)
Considerable chain tension (Ta) <Maximum allowable stress
If this situation will not be satisfied, choose a larger chain by one particular dimension and re-calculate.
Tentative determination of chain size
qDetermine the mass (weight) per unit length of elements such as chain and attachment ωc (kg/m or kgf/m) assuming that it really is ten percent with the mass (weight) of the conveyed object ω1 (kg/m or kgf/m).
wIn reference for the calculation formulas on, get “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “Substantial chain stress (Ta)” (kN or kgf).
eIn reference towards the table of dimensions of chains,recognize the minimum chain, whose “maximum allowable tension” is greater compared to the “Substantial chain stress (Ta)”, and regard it as “tentatively made the decision chain”.
Value of speed coefficient (K)
The speed coefficient (K) expresses the severity of operation situation according to the traveling velocity of chain since the issue becomes severer since the traveling speed of chain gets to be greater.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to get “Substantial chain tension (Ta)”.
