Calculation of Chain Stress
In general, at first, tentatively determine the chain size for being applied referring to “Tentative determination of chain size”. Then, receive “Theoretical chain tension (T)” (P213) to the tentatively established chain, and multiply the value by “Speed coefficient (K)”, to obtain “Substantial chain tension (Ta)”. For safety, the significant chain stress have to be reduce compared to the “maximum allowable tension” stated in the table of dimensions of respective chains. Consequently, the problem under should be happy.
Safety ailment of chain tension
Considerable chain stress (Ta) ＝Theoretical chain tension (T) ×Speed coefficient (K)
Significant chain stress (Ta) ＜Maximum allowable tension
If this issue is not pleased, decide on a larger chain by one particular size 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 10 percent in the mass (bodyweight) of your conveyed object ω1 (kg/m or kgf/m).
wIn reference towards the calculation formulas on, acquire “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain tension (Ta)” (kN or kgf).
eIn reference to your table of dimensions of chains,determine the minimal chain, whose “maximum allowable tension” is higher than the “Substantial chain stress (Ta)”, and regard it as “tentatively made a decision chain”.
Worth of speed coefficient (K)
The speed coefficient (K) expresses the severity of operation situation according towards the traveling velocity of chain since the situation turns into severer as the traveling speed of chain gets to be higher.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to obtain “Substantial chain stress (Ta)”.

When you layout a variety of conveyor methods using tiny conveyor chains, the following basic situations have to be satisfied.
a. Chain tension: The real tensile power in operation have to be drastically decrease than the specified power in the chain.
b. Strength of loaded parts of chain: The actual loads applied to attachments, such as rollers of base chain, leading rollers, side rollers, etc. in operation has to be considerably smaller sized compared to the power of those parts.
c. Wear daily life of chain: Lubrication circumstances to make sure the dress in daily life of chain needs to be fulfilled.
d. Sag adjustment of chain: The sag in the chain must be stored optimum by stress adjusters, take-up units, guides, and so on.
e. Others: Appropriate measures are taken to avoid rail put on, machine vibration along with other troubles.
The following complement the over.
