Calculation of Chain Stress
Generally, in the beginning, tentatively establish the chain dimension to get used referring to “Tentative determination of chain size”. Then, acquire “Theoretical chain stress (T)” (P213) to the tentatively established chain, and multiply the value by “Speed coefficient (K)”, to obtain “Substantial chain stress (Ta)”. For security, the significant chain tension needs to be decrease compared to the “maximum allowable tension” stated inside the table of dimensions of respective chains. Consequently, the situation below ought to be happy.
Safety situation of chain tension
Considerable chain tension (Ta) ＝Theoretical chain tension (T) ×Speed coefficient (K)
Significant chain tension (Ta) ＜Maximum allowable tension
If this situation will not be satisfied, decide on a bigger chain by 1 size and re-calculate.
Tentative determination of chain dimension
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 can be 10 % of the mass (weight) on the conveyed object ω1 (kg/m or kgf/m).
wIn reference to your calculation formulas on, obtain “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain stress (Ta)” (kN or kgf).
eIn reference to the table of dimensions of chains,determine the minimal chain, whose “maximum allowable tension” is greater than the “Substantial chain tension (Ta)”, and regard it as “tentatively made the decision chain”.
Worth of velocity coefficient (K)
The pace coefficient (K) expresses the severity of operation ailment in accordance to your traveling speed of chain since the problem gets severer since the traveling speed of chain turns into higher.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to obtain “Substantial chain stress (Ta)”.
Any time you design numerous conveyor systems working with modest conveyor chains, the next standard ailments has to be happy.
a. Chain tension: The real tensile power in operation should be substantially reduced compared to the specified power of your chain.
b. Strength of loaded elements of chain: The actual loads utilized to attachments, this kind of as rollers of base chain, prime rollers, side rollers, and so forth. in operation need to be substantially smaller sized than the power of those elements.
c. Wear life of chain: Lubrication ailments to ensure the put on existence of chain should be fulfilled.
d. Sag adjustment of chain: The sag on the chain has to be kept optimum by stress adjusters, take-up units, guides, and so on.
e. Other folks: Ideal measures are taken to avoid rail wear, machine vibration together with other problems.
The following complement the above.
