When you layout several conveyor systems working with smaller conveyor chains, the following fundamental ailments needs to be pleased.
a. Chain tension: The real tensile strength in operation has to be appreciably reduced compared to the specified power with the chain.
b. Strength of loaded components of chain: The real loads utilized to attachments, this kind of as rollers of base chain, top rollers, side rollers, etc. in operation have to be appreciably smaller than the strength of these parts.
c. Wear life of chain: Lubrication situations to make sure the put on daily life of chain need to be fulfilled.
d. Sag adjustment of chain: The sag from the chain has to be stored optimum by tension adjusters, take-up gadgets, guides, and so on.
e. Other individuals: Appropriate measures are taken to prevent rail wear, machine vibration as well as other issues.
The next complement the over.
Calculation of Chain Stress
On the whole, in the beginning, tentatively identify the chain size to be applied referring to “Tentative determination of chain size”. Then, get “Theoretical chain tension (T)” (P213) for that tentatively established chain, and multiply the value by “Speed coefficient (K)”, to acquire “Substantial chain stress (Ta)”. For security, the significant chain tension must be reduced than the “maximum allowable tension” stated within the table of dimensions of respective chains. Consequently, the issue below must be happy.
Safety ailment of chain 
stress
Significant chain tension (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain tension (Ta) ＜Maximum allowable stress
If this condition isn’t satisfied, choose a larger chain by a single size and re-calculate.
Tentative determination of chain size
qDetermine the mass (excess weight) per unit length of elements such as chain and attachment ωc (kg/m or kgf/m) assuming that it is actually 10 percent of the mass (excess weight) from the conveyed object ω1 (kg/m or kgf/m).
wIn reference to the calculation formulas on, get “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain stress (Ta)” (kN or kgf).
eIn reference to your table of dimensions of chains,determine the minimal chain, whose “maximum allowable tension” is larger than the “Substantial chain stress (Ta)”, and regard it as “tentatively determined chain”.
Worth of velocity coefficient (K)
The velocity coefficient (K) expresses the severity of operation affliction according for the traveling pace of chain since the affliction gets severer as the traveling velocity of chain gets higher.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to acquire “Substantial chain stress (Ta)”.
