If you style and design numerous conveyor methods making use of modest conveyor chains, the following essential problems have to be satisfied.
a. Chain tension: The real tensile power in operation have to be considerably lower than the specified strength from the chain.
b. Strength of loaded parts of chain: The actual loads applied to attachments, this kind of as rollers of base chain, top rollers, side rollers, etc. in operation has to be significantly smaller than the power of these parts.
c. Wear existence of chain: Lubrication circumstances to ensure the put on lifestyle of chain must be fulfilled.
d. Sag adjustment of chain: The sag in the chain have to be kept optimum by tension adjusters, take-up products, guides, and so forth.
e. Other folks: Acceptable measures are taken to avoid rail put on, machine vibration and various difficulties.
The next complement the above.

Calculation of Chain Tension
Normally, at the outset, tentatively decide the chain size to be employed referring to “Tentative determination of chain size”. Then, get “Theoretical chain stress (T)” (P213) for your tentatively determined chain, and multiply the value by “Speed coefficient (K)”, to acquire “Substantial chain stress (Ta)”. For safety, the substantial chain stress should be reduce compared to the “maximum allowable tension” stated inside the table of dimensions of respective chains. Consequently, the ailment below should be satisfied.
Safety issue of chain stress
Considerable chain tension (Ta) =Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain tension (Ta) <Maximum allowable tension
If this condition is not happy, decide on a bigger chain by 1 dimension and re-calculate.
Tentative determination of chain size
qDetermine the mass (excess weight) per unit length of parts such as chain and attachment ωc (kg/m or kgf/m) assuming that it’s 10 percent from the mass (bodyweight) with the conveyed object ω1 (kg/m or kgf/m).
wIn reference towards the calculation formulas on, acquire “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “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 compared to the “Substantial chain tension (Ta)”, and regard it as “tentatively decided chain”.
Value of speed coefficient (K)
The pace coefficient (K) expresses the severity of operation situation according for the traveling pace of chain because the ailment gets to be severer because the traveling pace of chain turns into higher.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to get “Substantial chain stress (Ta)”.
