5.3.6 Radial wobble of bowl
spindle
•
Spindle wobble is indicated by rough bowl run
(vibration).
The bowl spindle wobble should be checked if the
bowl spindle has been dismantled or if rough bowl
running (vibration) occurs.
NOTE
Spindle wobble will cause rough bowl run.
This leads to vibration and reduces lifetime of
ball bearings.
Check the wobble before mounting the bowl.
Before measuring, make sure that the buffer
plugs are properly tightened.
•
Fit a dial indicator in a support and fasten it to
the frame.
•
Remove the motor to get access to the
coupling drum. Use the coupling drum to
revolve the spindle manually.
•
Measure the wobble at the top of the tapered
end of the spindle. Maximum permissible
radial wobble is 0.15 mm.
•
If wobble is too large, renew all the ball
bearings on the spindle.
Measure wobble after assembly. If it is still
excessive, the spindle is probably damaged and
must be renewed, contact your Alfa Laval
representative.
