Calculation of Chain Stress
Normally, in the beginning, tentatively figure out the chain dimension to become made use of referring to “Tentative determination of chain size”. Then, obtain “Theoretical chain tension (T)” (P213) for the tentatively determined chain, and multiply the value by “Speed coefficient (K)”, to obtain “Substantial chain stress (Ta)”. For safety, the significant chain tension have to be reduced than the “maximum allowable tension” stated inside the table of dimensions of respective chains. Consequently, the ailment below need to be satisfied.
Safety issue of chain stress
Considerable chain tension (Ta) ＝Theoretical chain tension (T) ×Speed coefficient (K)
Substantial chain stress (Ta) ＜Maximum allowable tension
If this problem is not really satisfied, select a bigger chain by a single dimension and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (bodyweight) per unit length of parts such as chain and attachment ωc (kg/m or kgf/m) assuming that it really is 10 % from the mass (excess weight) on the conveyed object ω1 (kg/m or kgf/m).
wIn reference on the calculation formulas on, get “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “Substantial chain tension (Ta)” (kN or kgf).
eIn reference towards the table of dimensions of chains,recognize the minimal chain, whose “maximum allowable tension” is larger than the “Substantial chain stress (Ta)”, and regard it as “tentatively made the decision chain”.
Worth of speed coefficient (K)
The pace coefficient (K) expresses the severity of operation affliction in accordance towards the traveling velocity of chain since the situation turns into severer because the traveling velocity of chain gets to be larger.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to get “Substantial chain stress (Ta)”.

If you style and design many conveyor methods working with little conveyor chains, the following basic circumstances have to be content.
a. Chain tension: The actual tensile strength in operation have to be substantially lower than the specified power from the chain.
b. Strength of loaded components of chain: The actual loads applied to attachments, this kind of as rollers of base chain, top rollers, side rollers, etc. in operation needs to be significantly smaller sized compared to the power of these elements.
c. Wear existence of chain: Lubrication disorders to ensure the wear daily life of chain has to be fulfilled.
d. Sag adjustment of chain: The sag with the chain have to be kept optimum by stress adjusters, take-up products, guides, etc.
e. Many others: Ideal measures are taken to prevent rail wear, machine vibration together with other problems.
The next complement the over.
