If you layout many conveyor methods applying tiny conveyor chains, the next simple problems needs to be satisfied.
a. Chain stress: The actual tensile strength in operation has to be considerably reduce than the specified strength from the chain.
b. Strength of loaded parts of chain: The actual loads utilized to attachments, such as rollers of base chain, best rollers, side rollers, and so on. in operation should be drastically smaller compared to the power of those components.
c. Wear existence of chain: Lubrication situations to make sure the put on daily life of chain has to be fulfilled.
d. Sag adjustment of chain: The sag in the chain should be stored optimum by tension adjusters, take-up products, guides, etc.
e. Other individuals: Appropriate measures are taken to stop rail wear, machine vibration as well as other challenges.
The following complement the above.
Calculation of Chain Tension
Normally, initially, tentatively establish the chain dimension to be utilized referring to “Tentative determination of chain size”. Then, acquire “Theoretical chain stress (T)” (P213) for that tentatively established chain, and multiply the value by “Speed coefficient (K)”, to get “Substantial chain tension (Ta)”. For safety, the significant chain stress have to be lower than the “maximum allowable tension” stated in the table of dimensions of respective chains. Consequently, the condition below need to be content.
Safety problem of chain stress
Considerable chain tension (Ta) ＝Theoretical chain tension (T) ×Speed coefficient (K)
Substantial chain stress (Ta) ＜Maximum allowable tension
If this ailment is just not pleased, select a bigger chain by 1 size and re-calculate.
Tentative determination of chain dimension
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 ten percent in the mass (bodyweight) with the conveyed object ω1 (kg/m or kgf/m).
wIn reference towards the calculation formulas on, get “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain tension (Ta)” (kN or kgf).
eIn reference towards the table of dimensions of chains,identify the minimum chain, whose “maximum allowable tension” is increased than the “Substantial chain tension (Ta)”, and regard it as “tentatively 
made the decision chain”.
Value of pace coefficient (K)
The velocity coefficient (K) expresses the severity of operation issue in accordance to the traveling speed of chain because the issue gets severer as the traveling velocity of chain gets to be increased.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to get “Substantial chain stress (Ta)”.
