Table A-7: Maximum permissible shaft misalignment values during operation
You can calculate the numerical values in the table and their intermediate values as follows:
ΔKr
perm
= ΔS
perm
= (0.1 + DA / 1,000) · 40 / √n Coupling speed n in rpm
DA in mm (see Speeds, geometry data and
weights (Page 63))
Radial misalignment ΔKr
perm
in mm
The values in column "250 rpm" of the table above apply for speeds of < 250 rpm.
