Calculation of Chain Tension
Generally, to start with, tentatively establish the chain dimension to become 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 obtain “Substantial chain tension (Ta)”. For safety, the significant chain tension must be lower than the “maximum allowable tension” stated within the table of dimensions of respective chains. Consequently, the ailment below must be content.
Safety situation of chain tension
Significant chain stress (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain stress (Ta) ＜Maximum allowable stress
If this problem is just not satisfied, choose a larger chain by a single dimension and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (bodyweight) per unit length of components such as chain and attachment ωc (kg/m or kgf/m) assuming that it’s ten percent with the mass (weight) on the conveyed object ω1 (kg/m or kgf/m).
wIn reference on the calculation formulas on, receive “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain stress (Ta)” (kN or kgf).
eIn reference on the table of dimensions of chains,determine the minimal chain, whose “maximum allowable tension” is greater than the “Substantial chain stress (Ta)”, and regard it as “tentatively determined chain”.
Worth of pace coefficient (K)
The pace coefficient (K) expresses the severity of operation condition in accordance to your traveling velocity of chain since the ailment gets to be severer since the traveling speed of chain becomes higher.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to get “Substantial chain stress (Ta)”.
Once you design numerous conveyor techniques employing little conveyor chains, the following essential circumstances has to be pleased.
a. Chain tension: The real tensile strength in operation must be significantly lower compared to the specified power of your chain.
b. Strength of loaded elements of chain: The real loads utilized to attachments, such as rollers of base chain, top rollers, side rollers, etc. in operation needs to be substantially smaller sized compared to the strength of those components.
c. Wear lifestyle of chain: Lubrication disorders to ensure the wear life of chain needs to be fulfilled.
d. Sag adjustment of chain: The sag from the chain have to be stored optimum by tension adjusters, take-up gadgets, guides, and so on.
e. Others: Proper measures are taken to prevent rail put on, machine vibration and various difficulties.
The next complement the above.
