Calculation of Chain Stress

In general, to start with, tentatively establish the chain dimension to get applied referring to “Tentative determination of chain size”. Then, get “Theoretical chain tension (T)” (P213) to the tentatively determined chain, and multiply the value by “Speed coefficient (K)”, to acquire “Substantial chain stress (Ta)”. For safety, the considerable chain stress needs to be lower compared to the “maximum allowable tension” stated from the table of dimensions of respective chains. Consequently, the issue beneath should be happy.

Security condition of chain tension

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

Substantial chain stress (Ta) ＜Maximum allowable stress

If this affliction is not content, choose a larger chain by 1 size and re-calculate.

Tentative determination of chain size

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

wIn reference for the calculation formulas on, obtain “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain stress (Ta)” (kN or kgf).

eIn reference for the table of dimensions of chains,identify the minimum chain, whose “maximum allowable tension” is higher than the “Substantial chain tension (Ta)”, and regard it as “tentatively made a 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 ailment gets to be severer as the traveling pace of chain gets to be higher.

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

When you style different conveyor systems using compact conveyor chains, the next basic problems need to be satisfied.

a. Chain stress: The actual tensile power in operation needs to be considerably lower than the specified power in the chain.

b. Strength of loaded components of chain: The real loads applied to attachments, this kind of as rollers of base chain, top rated rollers, side rollers, and so on. in operation needs to be appreciably smaller compared to the power of those components.

c. Wear daily life of chain: Lubrication problems to guarantee the wear existence of chain needs to be fulfilled.

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

e. Other individuals: Appropriate measures are taken to prevent rail wear, machine vibration together with other problems.

The following complement the above.
