Calculation of Chain Tension
On the whole, at the outset, tentatively identify the chain size to become employed referring to “Tentative determination of chain size”. Then, obtain “Theoretical chain stress (T)” (P213) for that tentatively established chain, and multiply the worth by “Speed coefficient (K)”, to obtain “Substantial chain tension (Ta)”. For security, the substantial chain tension have to be reduced than the “maximum allowable tension” stated inside the table of dimensions of respective chains. Consequently, the condition under needs to be content.
Security problem of chain stress
Substantial chain tension (Ta) ＝Theoretical chain tension (T) ×Speed coefficient (K)
Significant chain tension (Ta) ＜Maximum allowable tension
If this situation is just not pleased, decide on a larger chain by one particular 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 is actually ten percent from the mass (weight) with the conveyed object ω1 (kg/m or kgf/m).
wIn reference on the calculation formulas on, acquire “Theoretical chain stress (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain tension (Ta)” (kN or kgf).
eIn reference to your table of dimensions of chains,determine the minimal chain, whose “maximum allowable tension” is larger compared to the “Substantial chain stress (Ta)”, and regard it as “tentatively decided chain”.
Value of pace coefficient (K)
The speed coefficient (K) expresses the severity of operation situation according for the traveling pace of chain because the issue gets severer as the traveling speed of chain gets greater.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to acquire “Substantial chain tension (Ta)”.
If you style and design several conveyor methods working with little conveyor chains, the following primary disorders must be pleased.
a. Chain tension: The real tensile strength in operation has to be appreciably reduce compared to the specified power of your chain.
b. Strength of loaded elements of chain: The actual loads utilized to attachments, this kind of as rollers of base chain, top rollers, side rollers, and so forth. in operation should be substantially smaller sized compared to the power of these elements.
c. Wear lifestyle of chain: Lubrication conditions to ensure the dress in daily life of chain should be fulfilled.
d. Sag adjustment of chain: The sag in the chain must be stored optimum by stress adjusters, take-up units, guides, and so on.
e. Some others: Proper measures are taken to stop rail dress in, machine vibration and other troubles.
The next complement the over.
