Tab. 3
Determining the deformation of the mounting structure
Under maximum operating load an appropriate deformation of the
mounting structure occurs. The dimensions can be detected via
dial gauges, laser measurement processes, or 3D measuring
systems.
Because in some cases measurement in operation is difficult,
determination of deformation can also be executed
mathematically, e.g. with the finite element method.
Alternatively you can also reference comparable measurements on
test rigs.
For slew drives that are between the specified sizes, always
assume the smaller value. For slew drives that are larger than
the largest diameter, use the largest specified value.
The slew drive must be supported by the mounting structure up
to the diameter specified in the slew drive drawing. All the
installed dimensions as specified in the drawing must be
complied with.
