Calculation of Chain Tension

On the whole, in the beginning, tentatively establish the chain size for being utilized referring to “Tentative determination of chain size”. Then, acquire “Theoretical chain stress (T)” (P213) for that tentatively determined chain, and multiply the value by “Speed coefficient (K)”, to acquire “Substantial chain stress (Ta)”. For security, the significant chain stress has to be lower compared to the “maximum allowable tension” stated while in the table of dimensions of respective chains. Consequently, the problem under must be happy.

Security ailment of chain stress

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

Considerable chain tension (Ta) ＜Maximum allowable tension

If this affliction isn’t content, select a bigger chain by one particular dimension and re-calculate.

Tentative determination of chain dimension

qDetermine the mass (excess weight) per unit length of parts this kind of as chain and attachment ωc (kg/m or kgf/m) assuming that it is ten % from the mass (weight) from the conveyed object ω1 (kg/m or kgf/m).

wIn reference on the calculation formulas on, get “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and calculate “Substantial chain tension (Ta)” (kN or kgf).

eIn reference on the table of dimensions of chains,determine the minimal chain, whose “maximum allowable tension” is higher compared to the “Substantial chain stress (Ta)”, and regard it as “tentatively determined chain”.

Worth of speed coefficient (K)

The velocity coefficient (K) expresses the severity of operation ailment in accordance to your traveling velocity of chain because the problem turns into severer as the traveling velocity of chain gets to be increased.

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

Whenever you layout different conveyor systems applying smaller conveyor chains, the following essential ailments must be satisfied.

a. Chain stress: The real tensile power in operation has to be appreciably reduce compared to the specified power on the chain.

b. Strength of loaded parts of chain: The real loads utilized to attachments, such as rollers of base chain, major rollers, side rollers, and so forth. in operation need to be significantly smaller than the power of these elements.

c. Wear lifestyle of chain: Lubrication problems to be sure the dress in lifestyle of chain has to be fulfilled.

d. Sag adjustment of chain: The sag on the chain need to be stored optimum by tension adjusters, take-up units, guides, and so forth.

e. Other people: Acceptable measures are taken to stop rail put on, machine vibration and various problems.

The following complement the above.
