5.4.4i Short flex
5.4.4ii Single plane
5.4.4iii Cardan shafts
Short flex is for most
common types of
“compact” flexible
coupling. Coupling results
may be displayed either
as ‘Angle/Offset’ or ‘Gap/
Offset’.
Single plane is for simple
non-flexible couplings which
are usually just two flanges
bolted together. Coupling
results may be displayed
either as ‘Angle’ or ‘Gap’.
Cardan is for couplings with
large offsets joined together
by a spacer shaft and
universal joints. Results are
displayed in cardan angles.
