11.6 Measures to be Taken in the Case of Faulty Assembly
Note: The following measures apply only to a rotor with a step
interference fit. Assembly mistakes for rotors with a smooth
shaft cannot be corrected!
Error:
Spindle gets stuck in the rotor during the shrink-fitting process
before reaching its final position.
Proceed as follows:
1. Let the rotor and spindle cool.
2. Seal one of the two pressure oil connections on the rotor with a
threaded pin. This means screwing the threaded pin in all the way
and securing it against turning with LOCITE 620 (for gluing
guidelines, see section 11.3). The threaded pin must be glued into
place in such a way that it completely seals the connection against
oil pressure.
3. Force the rotor off of the spindle with the help of the pressure oil (as
described below under "Removing the rotor from the spindle").
4. Check the tolerances of the press fits.
5. If necessary, remove burrs from the inside diameter of the rotor and
at press fits
Ød1 and Ød2 of the spindle.
Note: Both the spindle and the rotor must be absolutely free of
burrs!
Shrink-fit the rotor onto the spindle again.
Error:
The spindle is warped after the rotor has been shrink-fitted.
Tension in the step interference fit can occur during shrink-fitting. These
can cause spindle deformations in the micrometer size range. This
tension and the deformations are removed by forcing oil into the step
interference fit.
