Calculation of Chain Tension

On the whole, initially, tentatively identify the chain dimension for being utilized referring to “Tentative determination of chain size”. Then, get “Theoretical chain stress (T)” (P213) for your tentatively established chain, and multiply the worth by “Speed coefficient (K)”, to get “Substantial chain tension (Ta)”. For safety, the substantial chain stress needs to be lower compared to the “maximum allowable tension” stated in the table of dimensions of respective chains. Consequently, the affliction below needs to be pleased.

Safety problem of chain tension

Considerable chain stress (Ta) ＝Theoretical chain tension (T) ×Speed coefficient (K)

Considerable chain stress (Ta) ＜Maximum allowable tension

If this ailment isn’t pleased, pick a bigger chain by one particular size and re-calculate.

Tentative determination of chain dimension

qDetermine the mass (excess weight) per unit length of parts such as chain and attachment ωc (kg/m or kgf/m) assuming that it can be ten % in the mass (weight) with 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 determine “Substantial chain stress (Ta)” (kN or kgf).

eIn reference towards the table of dimensions of chains,determine the minimum chain, whose “maximum allowable tension” is larger than the “Substantial chain stress (Ta)”, and regard it as “tentatively made the decision chain”.

Worth of pace coefficient (K)

The speed coefficient (K) expresses the severity of operation issue according to your traveling velocity of chain because the condition gets severer because the traveling velocity of chain becomes increased.

Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to get “Substantial chain tension (Ta)”.

Any time you style different conveyor techniques making use of smaller conveyor chains, the following standard conditions need to be content.

a. Chain stress: The real tensile power in operation has to be drastically reduce than the specified strength on the chain.

b. Strength of loaded elements of chain: The real loads applied to attachments, such as rollers of base chain, best rollers, side rollers, and so forth. in operation have to be significantly smaller compared to the strength of those elements.

c. Wear lifestyle of chain: Lubrication disorders to ensure the wear life of chain must be fulfilled.

d. Sag adjustment of chain: The sag with the chain need to be stored optimum by tension adjusters, take-up units, guides, and so on.

e. Many others: Appropriate measures are taken to prevent rail dress in, machine vibration along with other challenges.

The next complement the above.
