When you design various conveyor programs using smaller conveyor chains, the next primary situations needs to be pleased.
a. Chain stress: The real tensile strength in operation needs to be considerably decrease compared to the specified strength of the chain.
b. Strength of loaded parts of chain: The actual loads applied to attachments, this kind of as rollers of base chain, leading rollers, side rollers, and so on. in operation must be significantly smaller sized compared to the strength of those parts.
c. Wear life of chain: Lubrication ailments to ensure the dress in daily life of chain should be fulfilled.
d. Sag adjustment of chain: The sag of the chain must be stored optimum by tension adjusters, take-up devices, guides, and so on.
e. Others: Proper measures are taken to stop rail put on, machine vibration together with other complications.
The following complement the over.

Calculation of Chain Tension
On the whole, at the outset, tentatively figure out the chain size to be applied referring to “Tentative determination of chain size”. Then, get “Theoretical chain stress (T)” (P213) to the tentatively established chain, and multiply the value by “Speed coefficient (K)”, to get “Substantial chain stress (Ta)”. For safety, the significant chain stress needs to be reduced compared to the “maximum allowable tension” stated while in the table of dimensions of respective chains. Consequently, the condition beneath ought to be satisfied.
Security issue of chain stress
Considerable chain stress (Ta) =Theoretical chain stress (T) ×Speed coefficient (K)
Substantial chain stress (Ta) <Maximum allowable stress
If this issue is just not satisfied, select a larger 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 percent of your mass (fat) in the conveyed object ω1 (kg/m or kgf/m).
wIn reference to the calculation formulas on, obtain “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “Substantial chain tension (Ta)” (kN or kgf).
eIn reference to your table of dimensions of chains,recognize the minimum chain, whose “maximum allowable tension” is greater than the “Substantial chain stress (Ta)”, and regard it as “tentatively made the decision chain”.
Value of pace coefficient (K)
The speed coefficient (K) expresses the severity of operation situation in accordance on the traveling pace of chain since the condition becomes severer since the traveling speed of chain gets larger.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to get “Substantial chain stress (Ta)”.
