Once you design numerous conveyor methods working with little conveyor chains, the following standard circumstances has to be satisfied.
a. Chain stress: The actual tensile power in operation need to be substantially lower compared to the specified strength from 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 need to be appreciably smaller compared to the power of those components.
c. Wear lifestyle of chain: Lubrication problems to make certain the put on life of chain have to be fulfilled.
d. Sag adjustment of chain: The sag on the chain needs to be stored optimum by stress adjusters, take-up products, guides, and so forth.
e. Others: Proper measures are taken to stop rail dress in, machine vibration and various problems.
The next complement the above.

Calculation of Chain Stress
Normally, at first, tentatively figure out the chain size to become employed referring to “Tentative determination of chain size”. Then, receive “Theoretical chain stress (T)” (P213) for the tentatively established chain, and multiply the worth by “Speed coefficient (K)”, to acquire “Substantial chain tension (Ta)”. For safety, the substantial chain tension have to be decrease compared to the “maximum allowable tension” stated inside the table of dimensions of respective chains. Consequently, the condition below must be satisfied.
Safety problem of chain tension
Substantial chain tension (Ta) =Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain tension (Ta) <Maximum allowable stress
If this affliction isn’t pleased, choose a bigger chain by one dimension and re-calculate.
Tentative determination of chain size
qDetermine the mass (excess weight) per unit length of components this kind of as chain and attachment ωc (kg/m or kgf/m) assuming that it’s ten % on the mass (bodyweight) on the conveyed object ω1 (kg/m or kgf/m).
wIn reference to your calculation formulas on, obtain “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain stress (Ta)” (kN or kgf).
eIn reference on the table of dimensions of chains,identify the minimum chain, whose “maximum allowable tension” is larger compared to the “Substantial chain tension (Ta)”, and regard it as “tentatively determined chain”.
Worth of speed coefficient (K)
The velocity coefficient (K) expresses the severity of operation problem according towards the traveling speed of chain since the condition becomes severer because the traveling velocity of chain becomes higher.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to obtain “Substantial chain tension (Ta)”.
