Fig. 12: Cleaning
When using cleaning agents, ensure adequate ventilation.
Maintain a strict ban on smoking.
Remove old grease, dust, and fouling with lint-free cloths.
Remove foreign material from the support surface of the
mounting structure (including paint residue, welding beads,
burrs).
If necessary clean the support surface of the slew drive.
Strictly comply with industrial safety regulations.
5.2.3
Determination of flatness deviation, and perpendicularity deviation and
deformation of the mounting structure
IMPORTANT
If there are impermissibly high deviations in flatness and
perpendicularity in the mounting structure, then rotational
resistance of the slew drive may significantly increase and
damage the entire slew drive. In the worst case the slew
drive may block.
If the permissible values for flatness or perpendicularity
deviation are exceeded, the mounting structure of the
slew drive shall be replaced or reworked.
Determination of flatness deviation, and perpendicularity deviation of the mounting structure
The mounting structure can be measured using a measuring plate
and dial gauges.
Laser processes and measuring with 3D systems have also proven
to be effective. These systems can be used without additional
auxiliary material, and they can document the actual gradient of
the mounting structure and process it accordingly.
