  Technical Data
 
The admissible radial load on the shaft
page 1 to 1
The allowed radial load force on the shaft is calculated with the following formula:

Fre      (N) Resulting radial load
M (Nm) Torque on the shaft
D (mm) Diameter of the transmission member mounted on the shaft
Fr (N) The admitted radial load force (see relative tables)
f z = 1.15 gear pinion
        1.4 chain wheel
        1.75 v-pulley
        2.5 flat pulley
When the resulting radial load is not applied on the centre line of the shaft, it is necessary to calculate
the effective load with the following formula:

a = worm casing constant
b = worm casing constant
x = distance of load from shaft shoulder(mm)
The values of a , b , x are given in the following tables
