PERMISSIBLE SHAFT LOAD
The value F
N
refers to the load at the middle of the shaft, distance L/2. It
is based on a sercive, life of 10,000 h and a speed of 1500 rpm. For other
speed and service life values, F
N
can be calculated with the aid of the graph
shown above. If additional axial forces occur, a recalculation of the bearing
load should be performed by the factory.
Example:
L
h
= 5000 h, n = 1000rpm
F/F
N
= 1.5 therefore F = 1.5 x F
N
OPERATION & MAINTENANCE
The KEB Combibox is shipped ready for installation with the air gap
preadjusted to the nominal value. NEMA, or IEC mounting dimensions on
the input and output ends allow for easy assembly to motors and gearboxes.
DO NOT FORCE FIT
when mounting. An antiseize lubricant should be used
on the shaft when mounting the Combibox. To avoid contamination of the
friction surfaces, do not use excessive amounts of lubricant.
Proper sizing of the Combibox in accordance with the application will
minimize wear and reduce maintenance. The air gap should be readjusted
according to the instructions when it reaches three times its nominal
