– If the machine is fitted with grease collection chambers :
!
Rotor can fall out
If the machine is in a vertical position, the rotor can fall out while work is
being performed on the locating bearing. This can result in death, serious
injury or material damage.
Support or relieve the rotor when carrying out work with the machine in a
vertical position.
Grease types
For the standard operating range, a grease for temperatures down to -20 ºC
is normally used for the initial greasing of rolling bearings. If the machine has
been ordered for use in the extended temperature range of below -20 ºC, the
permissible type of grease is indicated on the lubricant plate.
Note
Grease quantity control
The grease quantity control only operates correctly if the specified greases
are used. This is specified on plates attached to the machine.
7.1.8.4 Cleaning
Cleaning the grease ducts and spent grease chambers
The spent grease collects outside each bearing in the spent grease chamber of
the outer bearing cap. When replacing bearings, remove the spent grease.
Note
Dismantle the bearing cartridges to replace the grease in the lubrication duct.
Cleaning the cooling air ducts
Regularly clean the cooling air ducts through which the ambient air flows.
The frequency of the cleaning intervals depends on the local degree of
fouling.
132
Unbolt the grease collection chambers at the intervals shown on the
notice plate with the motor stopped, and remove the used bearing
grease. If this is not done, the grease will clog and the bearings will
overheat.
