When you design and style many conveyor methods utilizing small conveyor chains, the following primary disorders has to be satisfied.
a. Chain tension: The real tensile power in operation should be considerably decrease than the specified strength on the chain.
b. Strength of loaded elements of chain: The real loads applied to attachments, such as rollers of base chain, top rollers, side rollers, etc. in operation have to be drastically smaller sized compared to the power of those components.
c. Wear life of chain: Lubrication circumstances to ensure the put on daily life of chain have to be fulfilled.
d. Sag adjustment of chain: The sag in the chain needs to be kept optimum by tension adjusters, take-up products, guides, etc.
e. Other individuals: Suitable measures are taken to avoid rail wear, machine vibration together with other challenges.
The following complement the above.

Calculation of Chain Tension
Usually, in the beginning, tentatively establish the chain size to get applied referring to “Tentative determination of chain size”. Then, obtain “Theoretical chain stress (T)” (P213) for the tentatively determined chain, and multiply the value by “Speed coefficient (K)”, to obtain “Substantial chain tension (Ta)”. For security, the substantial chain tension should be reduce than the “maximum allowable tension” stated during the table of dimensions of respective chains. Consequently, the situation beneath need to be happy.
Safety condition of chain stress
Considerable chain stress (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain stress (Ta) ＜Maximum allowable tension
If this issue isn’t happy, choose a bigger chain by one particular dimension and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (weight) per unit length of elements such as chain and attachment ωc (kg/m or kgf/m) assuming that it is ten percent of the mass (bodyweight) with the conveyed object ω1 (kg/m or kgf/m).
wIn reference to the calculation formulas on, obtain “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “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 tension (Ta)”, and regard it as “tentatively made a decision chain”.
Worth of pace coefficient (K)
The speed coefficient (K) expresses the severity of operation issue in accordance on the traveling speed of chain since the problem gets severer because the traveling speed of chain becomes greater.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to acquire “Substantial chain tension (Ta)”.
