Calculation of Chain Tension
Generally, initially, tentatively identify the chain dimension for being used referring to “Tentative determination of chain size”. Then, get “Theoretical chain stress (T)” (P213) for that tentatively established chain, and multiply the worth by “Speed coefficient (K)”, to acquire “Substantial chain tension (Ta)”. For safety, the considerable chain stress should be decrease than the “maximum allowable tension” stated from the table of dimensions of respective chains. Consequently, the situation beneath should be pleased.
Security issue of chain stress
Considerable chain tension (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Substantial chain tension (Ta) ＜Maximum allowable tension
If this situation is just not content, select a larger chain by one dimension and re-calculate.
Tentative determination of chain dimension
qDetermine the mass (weight) per unit length of components this kind of as chain and attachment ωc (kg/m or kgf/m) assuming that it is actually 10 % from the mass (fat) with the 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 stress (Ta)” (kN or kgf).
eIn reference to your table of dimensions of chains,identify the minimal chain, whose “maximum allowable tension” is larger compared to the “Substantial chain stress (Ta)”, and regard it as “tentatively made a decision chain”.
Worth of speed coefficient (K)
The velocity coefficient (K) expresses the severity of operation situation according to your traveling velocity of chain since the ailment turns into severer since the traveling speed of chain gets increased.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to get “Substantial chain tension (Ta)”.
Whenever you design and style various conveyor methods using modest conveyor chains, the next basic disorders need to be pleased.
a. Chain tension: The real tensile strength in operation must be considerably reduce than the specified power of your chain.
b. Strength of loaded parts of chain: The actual loads applied to attachments, this kind of as rollers of base chain, top rollers, side rollers, and so on. in operation should be substantially smaller than the power of those elements.
c. Wear life of chain: Lubrication conditions to ensure the wear life of chain needs to be fulfilled.
d. Sag adjustment of chain: The sag with the chain needs to be kept optimum by stress adjusters, take-up units, guides, etc.
e. Others: Appropriate measures are taken to avoid rail put on, machine vibration and other troubles.
The following complement the above.
