When you style various conveyor systems applying little conveyor chains, the following primary situations have to be pleased.
a. Chain stress: The real tensile strength in operation should be drastically reduced compared to the specified strength of your chain.
b. Strength of loaded elements of chain: The real loads applied to attachments, this kind of as rollers of base chain, major rollers, side rollers, etc. in operation needs to be substantially smaller than the strength of these components.
c. Wear life of chain: Lubrication conditions to be sure the wear daily life of chain should be fulfilled.
d. Sag adjustment of chain: The sag in the chain has to be kept optimum by stress adjusters, take-up gadgets, guides, and so forth.
e. Other folks: Proper measures are taken to prevent rail put on, machine vibration along with other issues.
The next complement the over.
Calculation of Chain Tension
Normally, at first, tentatively decide the chain size to become applied referring to “Tentative determination of chain size”. Then, acquire “Theoretical chain stress (T)” (P213) for the tentatively established chain, and multiply the value by “Speed coefficient (K)”, to acquire “Substantial chain tension (Ta)”. For safety, the substantial chain tension should be reduced compared to the “maximum allowable tension” stated in the table of dimensions of respective chains. Consequently, the situation below must be content.
Security problem of chain tension
Substantial chain tension (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain stress (Ta) ＜Maximum allowable tension
If this condition is not satisfied, select a bigger chain by one particular size and re-calculate.
Tentative determination of chain size
qDetermine the mass (fat) per unit length of parts such as chain and attachment ωc (kg/m or kgf/m) assuming that it is 10 percent in the mass (fat) on the conveyed object ω1 (kg/m or kgf/m).
wIn reference for the calculation formulas on, obtain “Theoretical chain stress (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,identify the minimum chain, whose “maximum allowable tension” is higher than the “Substantial chain stress (Ta)”, and regard it as “tentatively made a decision chain”.
Value of pace coefficient (K)
The velocity coefficient (K) expresses the severity of operation problem in accordance towards the traveling velocity of chain since the problem becomes severer as the traveling velocity of chain gets to be greater.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to get “Substantial chain stress (Ta)”.
