Figure 5-16 Alignment process based on the example of a exible coupling
Note
It is advisable to insert shims or metal sheets under the mounting feet in order to align the drive
components in the vertical direction. It is helpful to use support paws with adjusting screws on
the foundation to adjust the drive components laterally.
Note
Gear unit with motor bell housing
Couplings do not have to be aligned if the gear unit and motor are connected through a motor
bell housing.
Further information
You can nd additional information about the permissible alignment errors for Flender
couplings in the complete documentation for the gear unit.
If couplings from other manufacturers are to be used, then, specifying the radial loads that
occur, ask the manufacturer which alignment errors are permissible.
Hollow output shaft and output ange shaft
There is no need to install the output-side coupling for gear units with a hollow output shaft or
anged output shaft.
