Type and quality of the shaft bearing have a major influence on the well-functioning
and the service life of the M.S.
Therefore, before installation of the M.S. both the
concentricity accuracy of the shaft
and the run-out accuracy between shaft and machine housing
have to be checked.
The maximum permitted axial displacements have to be considered, and the
instructions of the manufacturer have to be observed.
Concentricity accuracy
of the shaft (acc. to DIN ISO 5199):
Shaft diameters up to 50 mm:
max. 0.05 mm
Shaft diameters 50 mm - 100 mm:
max. 0.08 mm
Eccentricity
and
run out
as specified by EagleBurgmann!
Eccentricity
of the inner surface of the seal
chamber to the shaft:
max. 0.2 mm
Run-out accuracy
of the vertical contacting
surface between seal chamber and shaft axis:
Shaft speed ≤ 750 rpm: max. 0.2 mm
Shaft speed 1000 rpm: max. 0.15 mm
Shaft speed 1500 rpm: max. 0.08 mm
Shaft speed 3000 rpm: max. 0.025 mm
In case of installation into other machines the shown values apply as directive.
Prepare the assembly place, take away any not required tool, cuttings, dirty
cleaning wool etc.
Cover the work bench with a piece of clean, non-fibrous cardboard.
