Design chain pull(F_d)
4,775N
Pass

4.775 kN · 1,073 lbf

Effective pull multiplied by service factor.

Effective pull multiplied by service factor.

Also computed

Effective pull(F)3,183N

3.183 kN · 715.6 lbf

F = P / v.

Chain speed(v)1.571m/s

v = pi*D*n/60 at the pitch line.

Sprocket torque(T)159.2N·m

T = F*D/2.

Load utilization(U)0.5968

Design pull / allowable chain load.

Method notes 3 notes
  • Effective chain pull comes from transmitted power divided by pitch-line speed: F = P/v.
  • This is a steady running-tension check. Starting shock, impact, polygonal speed variation, chain sag, centrifugal pull, lubrication, wear and sprocket tooth capacity are not included.
  • Use the chain manufacturer rating, service factor and installation guidance for final selection.
