The radial loads is proportional to the requested torque and inversely proportional to the transmission member diameter following this formula.

FR =

2000 . T . T.e.f. N

D

FR = Radial load

T = Nm (Torque)

T.e.f. = Transmission element factor

T.e.f. = 1,15 gear

= 1,4 chain spocket

= 1,75 v-pulley

= 2,5 flat-pulley

D = Transmission element diameter

When the radial loads is not applied on the centre line of the shaft it is necessary to use the following formula.

FRx ≤

FR . a N

(b+x)

9

FR = Radial load on the centre line a,b,x = see table
