Choose appropriate chain from table 14.2 on page 550 for 15.600000 kW power transmitted at 1400.000000 rpm

Here, we choose chain 12B (18.15 kW rating)

Pitch circle diameter of the driving sprocket(D1) = 103.673741 mm

Pitch circle diameter of the driven sprocket(D2) = 206.462975 mm

Number of chain links(Ln) = 105.683011 or 106.000000

Correct centre distance between the sprockets(asag) = 763.496160 mm
