Calculation of Chain Tension
On the whole, at first, tentatively determine the chain size to be utilized referring to “Tentative determination of chain size”. Then, obtain “Theoretical chain stress (T)” (P213) for the tentatively established chain, and multiply the worth by “Speed coefficient (K)”, to get “Substantial chain tension (Ta)”. For security, the significant chain tension has to be reduced than the “maximum allowable tension” stated within the table of dimensions of respective chains. Consequently, the condition below must be pleased.
Security issue of chain stress
Significant chain stress (Ta) ＝Theoretical chain tension (T) ×Speed coefficient (K)
Significant chain tension (Ta) ＜Maximum allowable tension
If this condition is just not happy, decide on a bigger chain by one particular dimension and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (weight) per unit length of elements such as chain and attachment ωc (kg/m or kgf/m) assuming that it can be ten % in the mass (weight) on the conveyed object ω1 (kg/m or kgf/m).
wIn reference to your 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 to the table of dimensions of chains,determine the minimal chain, whose “maximum allowable tension” is larger compared to the “Substantial chain stress (Ta)”, and regard it as “tentatively determined chain”.
Value of pace coefficient (K)
The velocity coefficient (K) expresses the severity of operation problem according for the traveling pace of chain because the problem gets severer because the traveling speed of chain gets larger.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to acquire “Substantial chain stress (Ta)”.

Once you layout many conveyor techniques employing tiny conveyor chains, the following standard conditions should be pleased.
a. Chain tension: The real tensile strength in operation has to be appreciably reduced compared to the specified strength with the chain.
b. Strength of loaded parts of chain: The actual loads utilized to attachments, such as rollers of base chain, leading rollers, side rollers, etc. in operation has to be substantially smaller sized than the strength of these elements.
c. Wear lifestyle of chain: Lubrication disorders to make sure the put on life of chain has to be fulfilled.
d. Sag adjustment of chain: The sag from the chain must be stored optimum by stress adjusters, take-up products, guides, and so forth.
e. Many others: Acceptable measures are taken to stop rail put on, machine vibration as well as other difficulties.
The following complement the over.
