Bearings, Rings And Shafts - DAL-BO PowerRoll 1030 Manual

Bearings, rings and shafts:



Removal of roller shaft with rings for replacement of bearings, rings or shaft.
Should be done at a workshop.
Side section - REMOVAL:
This requires an approved crane which can lift at least 1000 kg.
Park the roller with the section in question beneath the crane - preferably
connected to a tractor. If there is no tractor, an hydraulic pump with two
double-acting valves will be required. The pump must be able to supply a
pressure of at least 160 bar.
Tie the opposite section in to the guide shackle above the transport bearing so
that it can still be moved up and down. Lift the side sections free from the
transport bearing with the large rams (red hoses). Swing the side section in
question approx. 1 m out to the side with the swing ram (blue hoses).
Attach carefully with two chains/straps around the rings approx. 1 m apart.
Lift until the chains/straps are taut. Undo the nuts by the bearings. Lift with
the crane until the screws are loose. Remove them, and the entire shaft can be
manoeuvred off.
Clean the grease off the bearing housing. Clean the projecting shaft end with
a file to remove any burrs. Undo the stop screws in the bearings. The
bearings can now be pulled out.
When the stopring with the two stop screws has been removed, the roller rings
can be pulled off the shaft.
ASSEMBLY:
Cambridge rings. After the outside stopring, fig. 7 pos.1, start with a smooth
ring with its "nose" pointing in, see fig. 7. Follow this with a serrated ring
with the smooth side facing out. It should go right up over the hub ("nose") of
the smooth ring.
Continue in the same way until approx. 12 cm is left. Omit the last serrated
ring. Make sure that the rings are tight up against each other.
