Calculation of Chain Tension

Usually, in the beginning, tentatively determine the chain dimension for being utilized 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 get “Substantial chain tension (Ta)”. For safety, the considerable chain stress has to be reduced compared to the “maximum allowable tension” stated inside the table of dimensions of respective chains. Consequently, the affliction beneath really should be satisfied.

Safety situation of chain tension

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

Considerable chain tension (Ta) ＜Maximum allowable stress

If this affliction will not be content, select a larger chain by a single dimension and re-calculate.

Tentative determination of chain dimension

qDetermine the mass (excess weight) per unit length of parts this kind of as chain and attachment ωc (kg/m or kgf/m) assuming that it can be 10 percent of your mass (weight) of your conveyed object ω1 (kg/m or kgf/m).

wIn reference for the calculation formulas on, acquire “Theoretical chain tension (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,identify the minimum chain, whose “maximum allowable tension” is increased than the “Substantial chain tension (Ta)”, and regard it as “tentatively determined chain”.

Value of pace coefficient (K)

The speed coefficient (K) expresses the severity of operation affliction according to your traveling pace of chain because the situation turns into severer because the traveling pace of chain turns into increased.

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

After you design and style many conveyor systems making use of small conveyor chains, the following basic circumstances need to be happy.

a. Chain tension: The actual tensile power in operation have to be significantly reduce compared to the specified strength of your chain.

b. Strength of loaded components of chain: The actual loads utilized to attachments, this kind of as rollers of base chain, top rollers, side rollers, etc. in operation has to be considerably smaller sized than the power of those components.

c. Wear life of chain: Lubrication disorders to make certain the dress in existence of chain need to be fulfilled.

d. Sag adjustment of chain: The sag with the chain have to be kept optimum by stress adjusters, take-up devices, guides, and so on.

e. Other individuals: Acceptable measures are taken to avoid rail dress in, machine vibration and also other problems.

The following complement the above.
