Calculation of Chain Tension
Usually, at the outset, tentatively identify the chain dimension to get applied referring to “Tentative determination of chain size”. Then, get “Theoretical chain stress (T)” (P213) for your tentatively established chain, and multiply the value by “Speed coefficient (K)”, to acquire “Substantial chain stress (Ta)”. For security, the considerable chain tension need to be reduce than the “maximum allowable tension” stated in the table of dimensions of respective chains. Consequently, the affliction below should be content.
Safety situation of chain stress
Considerable chain stress (Ta) ＝Theoretical chain tension (T) ×Speed coefficient (K)
Considerable chain tension (Ta) ＜Maximum allowable stress
If this ailment is just not content, pick a bigger chain by one dimension and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (fat) per unit length of components such as chain and attachment ωc (kg/m or kgf/m) assuming that it truly is ten % on the mass (excess weight) with the conveyed object ω1 (kg/m or kgf/m).
wIn reference on the calculation formulas on, obtain “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “Substantial chain stress (Ta)” (kN or kgf).
eIn reference to your table of dimensions of chains,recognize the minimum chain, whose “maximum allowable tension” is larger compared to the “Substantial chain tension (Ta)”, and regard it as “tentatively made the decision chain”.
Worth of pace coefficient (K)
The speed coefficient (K) expresses the severity of operation situation according to the traveling speed of chain because the ailment gets severer because the traveling velocity of chain gets higher.
Multiply “Theoretical chain tension (T)” by “Speed coefficient (K)” to obtain “Substantial chain tension (Ta)”.
If you style and design several conveyor methods using small conveyor chains, the next basic conditions has to be pleased.
a. Chain tension: The actual tensile strength in operation need to be considerably reduced compared to the specified strength of your chain.
b. Strength of loaded components of chain: The real loads applied to attachments, this kind of as rollers of base chain, top rollers, side rollers, etc. in operation must be substantially smaller compared to the strength of those elements.
c. Wear existence of chain: Lubrication ailments to ensure the put on daily life of chain have to be fulfilled.
d. Sag adjustment of chain: The sag with the chain must be kept optimum by stress adjusters, take-up units, guides, etc.
e. Some others: Acceptable measures are taken to avoid rail dress in, machine vibration along with other troubles.
The next complement the above.
