If you style different conveyor programs working with smaller conveyor chains, the next essential disorders should be pleased.

a. Chain tension: The actual tensile strength in operation has to be substantially decrease than the specified strength in the chain.

b. Strength of loaded elements of chain: The real loads applied to attachments, such as rollers of base chain, top rated rollers, side rollers, etc. in operation has to be considerably smaller compared to the power of those parts.

c. Wear life of chain: Lubrication ailments to be sure the dress in lifestyle of chain have to be fulfilled.

d. Sag adjustment of chain: The sag on the chain needs to be stored optimum by tension adjusters, take-up products, guides, etc.

e. Other folks: Proper measures are taken to prevent rail dress in, machine vibration and various issues.

The next complement the over.

Calculation of Chain Tension

On the whole, at the outset, tentatively determine the chain dimension to get utilised referring to “Tentative determination of chain size”. Then, obtain “Theoretical chain tension (T)” (P213) to the tentatively determined chain, and multiply the value by “Speed coefficient (K)”, to obtain “Substantial chain stress (Ta)”. For security, the considerable chain stress needs to be decrease compared to the “maximum allowable tension” stated in the table of dimensions of respective chains. Consequently, the problem beneath need to be content.

Safety issue of chain tension

Considerable chain tension (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)

Considerable chain tension (Ta) ＜Maximum allowable tension

If this condition will not be pleased, pick a bigger chain by a single size 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’s ten percent with the mass (bodyweight) of the conveyed object ω1 (kg/m or kgf/m).

wIn reference for the calculation formulas on, obtain “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,recognize the minimal chain, whose “maximum allowable tension” is increased than the “Substantial chain stress (Ta)”, and regard it as “tentatively made the decision chain”.

Value of speed coefficient (K)

The velocity coefficient (K) expresses the severity of operation condition according on the traveling speed of chain because the problem gets to be severer since the traveling velocity of chain turns into larger.

Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to acquire “Substantial chain tension (Ta)”.
