4.4 Permissible shift values
Flender H / HDS coupling
Never under any circumstances exceed the following shift
values of the coupling during operation.
4.4.1 Coupling size
Design H and HDS
The following table contains a list of coupling designations
and drill hole diameters.
4.4.2 Axial shift
U
S2
Design H and HDS
The following tables contain lists of permissible values for ax-
ial shift.
4.4.3 Angular shift
U
Kw
Angular shift
U
Kw is useful to measure as the difference of
gap dimension ( U S2=S2max - S2min). Permissible values
for the gap dimension may be seen in Tabelle 9.
4.4.4 Radial shift
U
Kr
The following table lists permissible shaft shift values for radi-
al shift
