Calculation of Chain Tension
In general, to start with, tentatively determine the chain size to become used referring to “Tentative determination of chain size”. Then, receive “Theoretical chain stress (T)” (P213) for that tentatively established chain, and multiply the value by “Speed coefficient (K)”, to get “Substantial chain stress (Ta)”. For security, the substantial chain stress have to be decrease compared to the “maximum allowable tension” stated during the table of dimensions of respective chains. Consequently, the affliction below must be happy.
Safety affliction of chain stress
Substantial chain stress (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Substantial chain tension (Ta) ＜Maximum allowable stress
If this ailment just isn’t happy, select a larger chain by 1 dimension and re-calculate.
Tentative determination of chain size
qDetermine the mass (fat) per unit length of elements this kind of as chain and attachment ωc (kg/m or kgf/m) assuming that it’s ten percent of your mass (weight) of your conveyed object ω1 (kg/m or kgf/m).
wIn reference towards the calculation formulas on, receive “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “Substantial chain tension (Ta)” (kN or kgf).
eIn reference for the table of dimensions of chains,recognize the minimum chain, whose “maximum allowable tension” is higher than the “Substantial chain tension (Ta)”, and regard it as “tentatively made a decision chain”.
Worth of pace coefficient (K)
The pace coefficient (K) expresses the severity of operation condition according for the traveling velocity of chain since the condition gets severer since the traveling velocity of chain becomes increased.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to obtain “Substantial chain tension (Ta)”.
After you style and design various conveyor programs using compact conveyor chains, the following essential situations has to be satisfied.
a. Chain stress: The actual tensile strength in operation needs to be significantly reduce than the specified strength with the chain.
b. Strength of loaded parts of chain: The actual loads applied to attachments, this kind 
of as rollers of base chain, leading rollers, side rollers, and so on. in operation should be drastically smaller than the strength of these parts.
c. Wear life of chain: Lubrication circumstances to be sure the wear existence of chain have to be fulfilled.
d. Sag adjustment of chain: The sag on the chain need to be kept optimum by tension adjusters, take-up units, guides, and so on.
e. Some others: Suitable measures are taken to avoid rail put on, machine vibration together with other difficulties.
The following complement the over.
