Power Take-Off (PTO) on Transfer Case Rotational Speed Per Distance Traveled (meter) Equations and Calculators

 

If the power take-off is operating on the transfer case and its operation is distance-dependent, its rotational speed n_N is given in revolutions per meter of distance covered. It is calculated from the following:

The distance s in meters covered per revolution of the power take-off (reciprocal value of n_N) is calculated with:

Distance per revolution, power take-off on the transfer case:

Where:

n_N = Power take-off rotational speed, in rpm
i_A = Final drive gear ratio
i_V = Transfer case gear ratio
r = Tire radius = 2 π r (m)
U = Tire circumference, (m) Typ. On-road = 1.007, typ. off-road = 1.652
s = Distance travelled, (m)
