The device is supplied assembled.
For the mounting, prepare the unit as follows :
- remove the drum �.
- take the safety-ring � and the closing-ring
from the hub �.
Mounting
After fitting the key into its housing :
- slide the driving member consisting of
the hub �, the inertia-blocks �, the springs
� etc... on the shaft ;
- stop this block laterally by means of either a
nut with its lock washer, or a safety-ring or a ring
with a screw, which will have to be locked by using
a thermoplastic liquid like for example “LOCTITE
brake-normal
thread”;
Warning
- For this setting process, never strike on the checks
� and springs �. Place a piece of soft alloy bet
ween the hub � and the system chosen for
pushing the block on the shaft.
- Center the drum � on the driven member or on
the frame of the machine and screw it into place.
Lock the screws energetically ;a thermoplastic
liquid like for example “LOCTITE brake-normal
thread” will provide for their stopping.
- Check in a few places, by using wedges, whether
the play between the inertia-blocks � packing and
the
internal diameter of the drum � is roughly
regular.
- Fit the closing-washer ➑ and put the safety-ring
� into its groove. To prevent the closing-washer
➑ rubbing against the drum �, keep the length
“L”.
- Counter-bore 2 holes opposite one another in
the driven member or in the frame of the machine
through the already existing ones in the
drum � and slip elastic pins of, for example, the
“MECANINDUS” type into these holes. (except
special drum)
- Engage or brake a few times in getting the
machine to work.
5 NOTES
Keep the inertia-blocks � packing off grease and
water, otherwise a reduction of the braking torque
could follow.
6 ADJUSTMENT
The centrifugal device FC-G needs no further
adjustment since it is originally set for a given torque.
The wear of the packing depends on the work
absorbed by this device
For replacing of used inertia-blocks, remove the
block consisting of the hub �, the inertia-blocks �,
the springs � etc... from the machine.
6. 1 – Disassembly
- take away the safety-ring � and the closing-
washer. �
- remove the screws fixing the drum �.
- dismount the drum � by screwing two of the fixing
screws into the tapped holes specially designed
for this purpose. (except special drum)
- remove from the shaft, the block consisting
of the hub �, the inertia-blocks � the
springs
� etc...
After having removed the above sub-assembly
- Insert conical wedges into space “A”, namely
between the 2 moving parts of the release-spring
� so that the inertia-blocks � do not bear any
more on the periphery of the hub � as a result of
the pressure from the springs �. If the
device is equipped with traditional draw
springs, stretch these springs with pliers in
order to relieve the inertia-blocks from the
pressure exerted by the springs.
- Remove the screws � on each face of the flanges
� and withdraw the used inertia-blocks. Do not
reverse the assembling direction of the springs.
- Put the new inertia-blocks � between the flanges
�, install the screws � while not for getting to
lock them by means of a thermoplastic liquid like,
for example, “LOCTITE brake-normal thread”.
- Drive away the conical wedges or let down
the draw-springs � in order to bring the inertia-
blocks
� into contact with the hub �.
- Reassemble the device on the machine. For this
process, see chapter 4 - ASSEMBLY.
