Calculation of Chain Stress
On the whole, at the 
outset, tentatively decide the chain dimension to become used referring to “Tentative determination of chain size”. Then, get “Theoretical chain tension (T)” (P213) for the tentatively established chain, and multiply the value by “Speed coefficient (K)”, to get “Substantial chain tension (Ta)”. For safety, the considerable chain tension have to be reduced compared to the “maximum allowable tension” stated from the table of dimensions of respective chains. Consequently, the situation beneath should be content.
Security condition of chain tension
Considerable chain tension (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Substantial chain stress (Ta) ＜Maximum allowable tension
If this condition is not pleased, select a larger chain by 1 size and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (fat) per unit length of parts this kind of as chain and attachment ωc (kg/m or kgf/m) assuming that it is actually 10 percent with the mass (excess weight) on the conveyed object ω1 (kg/m or kgf/m).
wIn reference for the calculation formulas on, receive “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 higher compared to the “Substantial chain stress (Ta)”, and regard it as “tentatively decided chain”.
Worth of velocity coefficient (K)
The speed coefficient (K) expresses the severity of operation condition in accordance to your traveling pace of chain since the ailment becomes severer because the traveling velocity of chain gets to be increased.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to acquire “Substantial chain tension (Ta)”.
Any time you style and design several conveyor systems applying little conveyor chains, the next fundamental circumstances should be happy.
a. Chain stress: The actual tensile strength in operation should be substantially decrease compared to the specified strength in the chain.
b. Strength of loaded parts of chain: The actual loads applied to attachments, this kind of as rollers of base chain, best rollers, side rollers, etc. in operation needs to be appreciably smaller sized than the power of those components.
c. Wear lifestyle of chain: Lubrication disorders to guarantee the wear daily life of chain must be fulfilled.
d. Sag adjustment of chain: The sag of your chain should be stored optimum by tension adjusters, take-up gadgets, guides, etc.
e. Many others: Suitable measures are taken to prevent rail dress in, machine vibration and other difficulties.
The following complement the above.
