Calculation of Chain Stress
Usually, at first, tentatively determine the chain dimension to get employed referring to “Tentative determination of chain size”. Then, acquire “Theoretical chain tension (T)” (P213) for your tentatively established chain, and multiply the value by “Speed coefficient (K)”, to get “Substantial chain tension (Ta)”. For safety, the considerable chain stress should be reduce compared to the “maximum allowable tension” stated inside the table of dimensions of respective chains. Consequently, the problem beneath needs to be satisfied.
Safety situation of chain tension
Substantial chain stress (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain stress (Ta) ＜Maximum allowable stress
If this affliction is not satisfied, select a larger chain by a single dimension and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (excess weight) per unit length of components such as chain and attachment ωc (kg/m or kgf/m) assuming that it truly is 10 % in the mass (excess weight) of the conveyed object ω1 (kg/m or kgf/m).
wIn reference towards the calculation formulas on, receive “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “Substantial chain tension (Ta)” (kN or kgf).
eIn reference on the table of dimensions of chains,identify the minimal chain, whose “maximum allowable tension” is higher compared to the “Substantial chain tension (Ta)”, and regard it as “tentatively made the decision chain”.
Value of speed coefficient (K)
The speed coefficient (K) expresses the severity of operation problem according for the traveling speed of chain since the issue turns into severer since the traveling speed of chain gets to be larger.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to acquire “Substantial chain tension (Ta)”.
When you layout several conveyor methods making use of smaller conveyor chains, the next primary 
situations should be happy.
a. Chain tension: The actual tensile strength in operation should be considerably reduced than the specified strength in the chain.
b. Strength of loaded components of chain: The actual loads applied to attachments, this kind of as rollers of base chain, leading rollers, side rollers, and so forth. in operation need to be considerably smaller compared to the strength of these elements.
c. Wear existence of chain: Lubrication circumstances to make sure the wear life of chain have to be fulfilled.
d. Sag adjustment of chain: The sag with the chain must be stored optimum by stress adjusters, take-up units, guides, and so forth.
e. Other individuals: Proper measures are taken to stop rail wear, machine vibration as well as other troubles.
The following complement the over.
