Calculation of Chain Tension
In general, in the beginning, tentatively ascertain the chain dimension to be utilized referring to “Tentative determination of chain size”. Then, acquire “Theoretical chain stress (T)” (P213) for your tentatively determined chain, and multiply the value by “Speed coefficient (K)”, to acquire “Substantial chain tension (Ta)”. For safety, the significant chain tension must be decrease compared to the “maximum allowable tension” stated during the table of dimensions of respective chains. Consequently, the condition under must be pleased.
Safety affliction of chain stress
Considerable chain stress (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Considerable chain tension (Ta) ＜Maximum allowable stress
If this problem is not satisfied, decide on a larger chain by one dimension and re-calculate.
Tentative determination of chain size
qDetermine the mass (excess weight) per unit length of components this kind of as chain and attachment ωc (kg/m or kgf/m) assuming that it can be 10 % in the mass (bodyweight) of your conveyed object ω1 (kg/m or kgf/m).
wIn reference on the calculation formulas on, receive “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain tension (Ta)” (kN or kgf).
eIn reference to the table of dimensions of chains,recognize the minimal chain, whose “maximum allowable tension” is higher than the “Substantial chain stress (Ta)”, and regard it as “tentatively decided chain”.
Value of pace coefficient (K)
The pace coefficient (K) expresses the severity of operation affliction in accordance to the traveling pace of chain because the affliction gets severer since the traveling pace of chain turns into higher.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to acquire “Substantial chain stress (Ta)”.
Once you design numerous conveyor methods utilizing little conveyor chains, the following essential conditions have to be content.
a. Chain stress: The actual tensile strength in operation should be significantly reduced compared to the specified power in the chain.
b. Strength of loaded components of chain: The actual loads utilized to attachments, such as rollers of base chain, leading rollers, side rollers, and so on. in operation have to be significantly smaller than the power of these parts.
c. Wear existence of chain: Lubrication circumstances to guarantee the wear daily life of chain must be fulfilled.
d. Sag adjustment of chain: The sag on the chain must be kept optimum by tension adjusters, take-up units, guides, and so on.
e. Many others: Suitable measures are taken to avoid rail put on, machine vibration and also other challenges.
The following complement the above.
