Hansen P4 Series User Manual

Combination of angular and radial misalignment
Angular and radial misalignment can occur simultaneously. The sum of the misalignments must satisfy the
following condition:
dr : measured radial misalignment
Δr : allowable radial misalignment
da : measured angular misalignment
Δa : allowable angular misalignment
6.4.2.2. Connection motor - gear unit : allowable misalignment at the high speed shaft (including all
shaft ends of single stage gear units)
(*) : Angular misalignment for coupling with a diameter of 100 mm or 10 inch
(**) : Radial misalignment for a spacer length of 100 mm or 1 inch
6.4.2.3 Alignment when mounting flexible gear couplings
When flexible gear couplings are mounted, the minimum allowable misalignment for the coupling may differ
from the values listed in the table of permissible misalignment (see above).
Refer to Hansen Industrial Transmissions nv to get the appropriate alignment instructions and service manual of
the gear coupling.
