Project Planning for Gear Units

On the input side:

Overhung load

conversion for

off-center force

application

Important: only applies to gear units with input shaft assembly:

Consult SEW-EURODRIVE for off-center force application on the drive end.

On the output

side: Overhung

load conversion

for off-center

force application

The permitted overhung loads must be calculated according the selection tables using

the following formulae in the event that force is not applied at the center of the shaft end.

The smaller of the two values F

(according to bearing life) and F

(according to shaft

strength) is the permitted value for the overhung load at point x. Note that the calcula-

tions apply to T
