Calculation of Chain Stress
Usually, at the outset, tentatively figure out the chain size to become utilized referring to “Tentative determination of chain size”. Then, get “Theoretical chain stress (T)” (P213) for that tentatively established chain, and multiply the value by “Speed coefficient (K)”, to obtain “Substantial chain stress (Ta)”. For safety, the substantial chain tension has to be lower than the “maximum allowable tension” stated during the table of dimensions of respective chains. Consequently, the ailment beneath must be content.
Safety affliction of chain tension
Considerable chain tension (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Substantial chain tension (Ta) ＜Maximum allowable tension
If this issue isn’t pleased, choose a bigger chain by a single dimension and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (weight) per unit length of elements this kind of as chain and attachment ωc (kg/m or kgf/m) assuming that it truly is ten % of the mass (bodyweight) with the conveyed object ω1 (kg/m or kgf/m).
wIn reference towards the calculation formulas on, get “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “Substantial chain stress (Ta)” (kN or kgf).
eIn reference for the table of dimensions of chains,determine the minimum chain, whose “maximum allowable tension” is greater than the “Substantial chain tension (Ta)”, and regard it as “tentatively determined chain”.
Value of velocity coefficient (K)
The speed coefficient (K) expresses the severity of operation situation in accordance towards the traveling pace of chain since the affliction gets to be severer since the traveling velocity of chain gets to be greater.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to get “Substantial chain tension (Ta)”.

If you layout different conveyor methods using little conveyor chains, the next essential conditions have to be satisfied.
a. Chain stress: The actual tensile strength in operation have to be substantially reduce than the specified power on the chain.
b. Strength of loaded parts of chain: The real loads utilized to attachments, such as rollers of base chain, major rollers, side rollers, etc. in operation has to be substantially smaller sized compared to the strength of those components.
c. Wear daily life of chain: Lubrication conditions to be sure the dress in life of chain has to be fulfilled.
d. Sag adjustment of chain: The sag of the chain need to be stored optimum by stress adjusters, take-up units, guides, and so forth.
e. Other individuals: Suitable measures are taken to stop rail wear, machine vibration and also other issues.
The next complement the over.
