•
Wobbling: shows how much the girth gear is not perpendicular to the axis of rotation.
It is a +/- value (blue arrow)
•
"Peak at": indicates the angle where the peak of the wobble is located. It is counted in
degrees after F9 was pressed. It is analogue to the value in radial direction (see above)
•
Straightness Deviation: shows the maximal deviation from the ideal plane surface.
It is a +/- value (green arrows)
•
Total Run-Out: is the combination of wobbling with straightness deviation. It corresponds
directly to the measured values. The Total Run-Out is a +/- value (red arrows)

Limits

TomTom-Tools GmbH does not provide guide lines about acceptable run-out limits.
It has to be according to the equipment manual or discussed with the suppliers, how much run-out
and roundness error can be allowed.
Out of experience the following table can be taken as an example for kiln girth gears but might
need to be adjusted to the specific case:
Run-Out [mm] As Installed
Radial ±0.035 M
Axial ±0.00015 D - 0.25
& Straightness Deviation
Need Re-Alignment
±0.0875 M
±0.000375 D - 0.25
