If you style various conveyor methods applying tiny conveyor chains, the following simple situations have to be happy.
a. Chain stress: The actual tensile power in operation need to be drastically reduce compared to the specified power in the chain.
b. Strength of loaded parts of chain: The real loads utilized to attachments, this kind of as rollers of base chain, leading rollers, side rollers, etc. in operation have to be appreciably smaller compared to the strength of these components.
c. Wear lifestyle of chain: Lubrication ailments to make certain the put on lifestyle of chain need to be fulfilled.
d. Sag adjustment of chain: The sag with the chain must be stored optimum by tension adjusters, take-up devices, guides, etc.
e. Other people: Suitable measures are taken to stop rail wear, machine vibration and other issues.
The following complement the above.
Calculation of Chain Stress
On the whole, initially, tentatively figure out the chain size to be utilized referring to “Tentative determination of chain size”. Then, receive “Theoretical chain tension (T)” (P213) for the tentatively established chain, and multiply the value by “Speed coefficient (K)”, to obtain “Substantial chain tension (Ta)”. For safety, the substantial chain tension have to be lower compared to the “maximum allowable tension” stated while in the table of dimensions of respective chains. Consequently, the situation below needs to be happy.
Safety problem of chain stress
Substantial chain tension (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain stress (Ta) ＜Maximum allowable stress
If this ailment just isn’t content, choose a bigger chain by one size and re-calculate.
Tentative determination of chain size
qDetermine the mass (weight) per unit length of components such as chain and attachment ωc (kg/m or kgf/m) assuming that it really is ten percent with the mass (fat) with the conveyed object ω1 (kg/m or kgf/m).
wIn reference to your calculation formulas on, acquire “Theoretical chain tension (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 minimum chain, whose “maximum allowable tension” is larger compared to the “Substantial chain stress (Ta)”, and regard it as “tentatively made the decision chain”.
Value of speed coefficient (K)
The velocity coefficient (K) expresses the severity of operation issue according for the traveling pace of chain because the situation becomes severer as the traveling velocity of chain gets to be higher.
Multiply “Theoretical chain tension (T)” by 
“Speed coefficient (K)” to get “Substantial chain stress (Ta)”.
